@Situ

some news about the FC3000 USB port. In the Spanish Telegram group there is this guy who has his controller connected to a PC. and that's what his pc does. Looks like the controller is some sort of custom USB device, so you seem right, the FC3000 USB connector seems to be wired to the GPIOs, and the stock firmware uses some sort of custom USB driver.

Some Updates...

UBOOT

• Raised RAM Speed from 156MHz to 216MHz (FC3000 did not boot with higher values)

GMENU2X

• Using Sourcecode from @Apaczer (miyoo-beta)

• Raised Max CPU from 864MHz(702MHz) to 960MHz (FC3000 hangs with higher values)

• Added Reboot option to PowerDialog

• Fixed the Battery Icons

• Reset CPU Speed for links is set to 960MHz

TODO

• Gather more current sourcecodes from emus/apps or executeables atleast

• Remove Experimental USB cause it seems USB is wired to GPIO instead to USB Port on ARMCPU

• ??? maybe still some things or EOL

@situ

do you let these guys intimidate you now?  stealing the work from others (ip, copyrighted games) and encrypting it in WST files and selling it for a profit.  According to the German law, he violated some things.  and he makes stress here because of "his" operating system?  Please go ahead and let the guy talk.

@司徒  @Kike

it worked!  thank's

@Situ

thank you <3

ok, i got the RB411-11A image working, it was the wrong initial code.

@Situ

i have an user from spain, he has the RB411-11A display, he downloaded my RB411-11A linux image but his display stays black.
i tried to recompile the uboot and gave him the image, stil black screen.

can you please compile a IPS1 (RB411-11A) uboot for me or look into source code why his display stays black?
maybe compiling a new uboot.img is enough and the issue lies at me.

thank you very much

PS:
I saw in the ips kernel patch file the last 2 lcd init cmd/data are

Lcd_Cmd(0x1020)
Lcd_Dat(0x1020)

But in your new kernel and uboot code, there is only

Lcd_Cmd(0x1020)

Is that correct or can be that the fault?

Here is a video of the new FC3000 firmware (crappy recording, looks much better in reallife)

https://youtu.be/C0NxH0gfZoY

@EVERYONE

@MOD: Please Delete post #1187, thank's

Updated Post #1187 with new Download Links for V1 old rev TFT and V2 IPS

@Situ
thanks for your commit, it works now.

@situ

do have have a little bit time for the old v1 tft1 uboot dual boot?
your commit did not work, sorry.

and i should tell you, a very big thank's and greetings from the 4PDA.RU forum

@zjzixuan

I saw your lcd ribbon and pcb pictures, looks not like an FC3000 handheld.
So our FC3000 images are not for your hardware if i see it correct.

what a genius!!!

now add 3D acceleration support , hahaha , just kidding

ok, another unknown display. do you tried different images?
if not, try the ips2 first please.

hint: if you look from an another angle onto your display and your images stays the the, you have an IPS display, if your image differs or inverts / change colors, you have an TFT display.

@zjzixuan

can you provide what is written on your LCD or LCD Ribbon cable?

ex:  WL-28H105-A1 or T2812-M106-24C-7D

@Situ

i just found out that your dual boot uboot did not start on the tft1 (variant=3) version, nothing happens(or it starts the stock rom, cant really tell cause my stock rom is wiped).
i tried an older working uboot source code and copied over your patched start.s and uboot did not boot into linux.

the tft1 version has no multiplex lines, SELECT is on (4*32)+3  (PE3)

PS: I bypassed your dual boot function for the FC3000 V1 TFT T2812-M106-24C-7D until you maybe feel like fixing it
(i have no clue of arm assembler).

kind regards and thank you so much for your work and help

@Situ

what do you think about my solution with dualboot?
remount /boot as RW and mount it as /mnt, and the fsck if dirty bit is set script?

@司徒

Why making an image?
My purpose was that we do not need an image anymore.
So the enduser did not have to resize partitons.

ok, after rethinking about it, i believe writing an image to sdcard and resize it is easier for an end-user.
maybe we can make a little tool for that? anyway, good job Stewen.

i got eduke32 source code from the official website i think.
would be great if we can compile higher versions.
you need todo some work to compile that code (Makefiles, Code editing etc).

https://dukeworld.duke4.net/eduke32/synthesis/old/2013/20131102-4128/

PS: i added more gore/guts and xxx patch (complete naked girls)

nude patched grp file
duke3d_20221006-1817.7z

more guts/gore GAME.CON (put file in dir where eduke32 executeable is)
GAME_CON.7z

thank you, it is compressing an eternity and downloads 3 x 2GB archive files.

ok, just fixed eduke32....

compiled eduke32_20131102-4128 successfully and it is working without disappearing/flicker issues.
still savegame and demo not working. and playanim() function need to be fixed again.

decodeframe() function patched, animations playing back again.

maybe i will try to compile higher versions.

@司徒

man, you are so skilled.
really strange how this CPU seems to not had math lessons in the elementary school, hahahha.

here is the "image" (!! FOR TESTING PURPOSE ONLY, NO FINAL IMAGE GUYS !!)
https://drive.google.com/file/d/1eEUu4_tPvH7hVs_U-Gwim441el1uvHnv/view?usp=sharing

1.    Create Partition 1 with 32MB in size (FS is not important)

2.    Create Partition 2 with the rest of your sdcard (fat32)
    (Windows does not allow bigger partitions than 32GB, only with third party tools like minitool partition wizard)

3.    Save Partition table to disk

4.    Delete Partition 1 so it is unallocated, save Partition table to disk

5.    DD your current/dualboot uboot.img to Partition 1

6.    Extract archive to the Fat32 Partition

7.    i added a fsck.vfat script when dirty bit is set (unclean shutdown), so it can take some time
    to boot if dirty bit is set.
    i do not know how important it is on an fat32 fs, but i added it because my solution is
    to remount /boot as RW and mount /boot on /mnt in inittab.
    maybe you can make it better (script is in /etc/vfatfsck.sh and is called in /etc/main).

- updated gmenu2x (press menu button for poweroff option)
- added reboot link in settings section

@司徒

you are soooo amazing man!!!!    so it seems a math error on fc3000 hardware. i will take a look into G_MoveActors().
but I think that not only X is the problem, I think Y and Z are also affected.

PS: bypassing A_GetZLimits(int32_t iActor) in source/gameexec.c keeps the enemies on screen. they still have some bugs but did not disappear or flicker (i can fight against them).

finaly some results!!!! 
thank you so much for your info <3

PPS: looks like the issue lies in getzrange() in build/src/engine.c, bypassing getzrange() in A_GetZLimits() has the same effekt as bypassing A_GetZLimits() complete.

@Situ

new system done!!

Created 2 partitions with minitool partition wizard, one 32MB and one with the rest of sdcard (win10 did not allow create fat32 partitions bigger than 32GB).
Deleted the first 32MB partition (32MB unalocated, 57GB Fat32).
dd uboot+kernel into the unallocated 32MB partition.
copied over my modded linux systemfiles to the big Fat32 partition, now the stock firmware and linux can access the /roms folder.
But looks like that the Stock NeoGeo emu accepts WST roms only.

- updated gngeo

EDUKE32
i think the error lies in drawsprite() function in engine.c, but i have not such a fast eye for buggy source code as you .

@Situ

i tried your dual boot feature. we have the problem now, stock firmware search roms on the first partition (FC3000) where the rootfs is.
this partition has not enough space and our other roms are on the second partition (OD).

only solution that came in mind is to put all files in first partition and mount that as /mnt, so we have /roms folder in stock firmware and /mnt/roms in linux firmware.

or link the folders if possible, idk.

@Situ

I solved the sound problem!
The FC3000 hardware doesn't seem to like the original VOC sound files.
I have now extracted all VOC files from duke3d.grp, converted them to WAV, renamed it to VOC and put it back into duke3d.grp.
no currupted sounds anymore!

duke3d.7z

i saved it, but preview picture is currupt, can not load back the save game, errors or savegame currupt in log file.

regarding sound issues:

i created a EDUKE.CON file with
"definesound ID FILE 0 0 0 0 0"
entrys from ID 0 to ID 2500.
every sound was replaced with a dummy wav file(a door close sound), no more currupt sounds, confused!

SAVEGAME + LOG
egam0.7z
eduke32.log.txt

MY EDUKE.CON + WAV FILE
EDUKE.CON.txt
NULL.7z

sorry, what do you mean exactly with savestate?

Thank's i will try that

@Situ

i try to change sounds from .grp file to wav/voc/ogg maybe that helps.

I play the same version on qemu and fc3000, on qemu eduke works fine but on fc3000 the enemies seems to fall trough the floor. (i saw 2 enemies in water but they had to be on the ground above).
enemies sometimes flicker or disappearing, very strange.

do you have any clue? i do not!

@Situ

duke has no sound problems in qemu, still has underruns but sound is not currupt as on the FC3000 hardware, enemies do not disappear in qemu also.

whats the difference between FC3000 HW and QEMU?

eduke32 is running without issues on QEMU!

Ahh, ok, get it. So if i want above 702 i must change the resistors like on the first pages, ok

Does it mean i can overclock the fc3000 now?
Everytime system hangs while starting an app when i set cpu over 702mhz.
Or is a resistor change mandatory?

X11?

does your gdb show something while the enemies are disappearing? maybe thats another kind of memory problem.

@司徒

A4) yes the V1 one but only in uboot L204, kernel is ok

regarding duke, you can set sound to on, sound is playing but distorted and currupt. it sounds like sound engine is not stoping playback, or has problems with alsa.

timidity has nothing todo with the game sound.

here is my rootfs with working tmidity setup if you want

Video of my Eduke32 sound and enemies issues
https://youtu.be/qUdhwwFIhHs

@司徒

do you have an FC3000 emulator?  why does the duke nukem screenshots have a window?

@司徒

Thank you very much <3 for the kind words.

It's amazing how you changed the compilation process and added the uboot logo, very good work.

A lot of people are contacting me over youtube for the linux images, looks like we helped a lot of users.

I will try it tomorrow.

Thank you for your help, i am curious about eduke32

Has anyone a clue why some emulators on linux are a bit slower than on the stock firmware.

Hi there,

here is my IPS V2 (WL-28h105-A1) Linux image.

- updated FBA
- added RetroArch
- added Duke3D Atomic Edition (but buggy as hell, sound and enemie issues)
- added Bootlogo
- Some little fixes

!! this time it has a new installation method in windows, watch my video !!

FC3000 in action
https://youtu.be/BlkkFCp-XCE

@Situ

Is your FC3000 running linux now?

@Apaczer

thank you very much, eduke32 has now music.
I copied over timidity.cfg, instruments/ and libSDL_mixer.so libs from miyoo rootfs and put it into the FC3000 rootfs.

todo...

- sound is very curupted (cracking and seems to play every sound file in the grp file)
- enemies deisappearing when duke looks at them or gets closer

ok guys, eduke32 is starting now...

- no music playing
- sound is distorted
- had to change in game.c var logoflags to (logoflags = LOGO_TITLESCREEN) in G_DisplayLogo() else eduke32 is exiting
- no mouse of course, was able to control duke with dpad

Ok, found out that libmi_sys.so is for an sigmastar cpu or something, maybe a miyoo needed library.

ahhh very cool, another CPU but a known LCD, uboot_ips2.img should work out of the box

@司徒

thank you very much. i have no clue about repos and maintaining them.
maybe you can look over mykernel and myuboot and replace your kernel and uboot sources (backup your kernel/uboot of course)
oh, the battery symbol is not showing the current battery level, maybe that needs to fix.

just found eduke32 on your website, i compiled it but on fc3000 init is failed cause no mouse found and libmi_sys.so not found.
is there a chance to get duke3d running on fc3000?

@Situ

i saw in your kernel source code you already patched in the ips init code, do you have the old tft init code still
(your lcd init code in sunivfb.c matches the kernel_fc3000_ips.patch)?

user @Aksenenkoav1990 is using the fc3000_tft_od_jckl_no_roms.img.7z image.
and i wanted to compile a uboot with his bootlogo for him.

PS: it looks like the same code atleast. or do the two displays have almost the same init code?

Forget the png2hex thing, here is a better tool i got from @Aksenenkoav1990

only thing you need is to add things like "uint16_t hex_splash[]={" and "};" manually

lcd-image-converter.7z

All right, i will still try it. Hope your FC3000 arrives fast 😄🤗.

I do not know this day, but happy midfall day

@Situ

ok, i converted your png2hex program to FreeBASIC, but something went wrong, bugfixing time... again!

buggy source code and windows executeable
img2hex.7z

screenshot

Thank you

@司徒

no, sadly did not work either. 
tft - screen flashes bright shortly, blackscreen/no backlight, logo flashes shortly before gmenu starts.
ips -screen flashes shortly but dimmed, blackscreen/no backlight, logo flashes shortly before gmenu starts.

i think there must be a (backlight on/off) command somewhere in the code.
ps: my logo seems a 24bit image, must create a 16bit.

https://youtu.be/mTNIlMzeqyE

@司徒

I will try it, but i think my backlight is off during this, seems like backlight is going on shortly before gmenu kicks in.
On the IPS FC3000 atleast.

@司徒

i do not want X11, it is an option for someone who is able to code linux. this device is allready open now and is running linux, in theory X11 on framebuffer should be doable, but i do not need it.

PS: just got the keypad working correctly now.

only thing i could need is how to enable boot logo again, i tried many things, but no logo was shown during boot

it is currently running linux without X11 but with an SDL based menu.
there is Doom, Quake, Lot of Emulators, Audio/Video Player ....

but i need to fix some butons, when you press L1, SELECT key is pressed too, R1 is START also.

are you a user(Txuseol) from a spanish forum?

Thank you, i just downloaded your fba binary, works great

@Situ
Thank you very much <3

I present you..... DOOM runing on the FC3000 V2 IPS (WL-28H105-A1) but guess what, the buttons are mapped different or my keyboard.c code is messed up.

feels like L1 is strafe left and SELECT, R1 is strafe right and START at the same time in Doom.
START and SELECT do nothing in Doom.

and I noticed with both FC3000 that the image has tearing, as if no vsync is on or something. can we fix that?

hahaha, farewell FC3000.

i tried already some init codes, only st7789 in swap RB order give me some garbage on screen and i can see that your test program tries to write data on the left side (the RGB stripes), but they are all Black and White

Just saw you already have an wl-28h105-a1 stock dump on github.  Only need to figure out what driver this display use

Yeah, me hahaha, i only need the display initial code as i learned.

I tried your lcd test image and i got garbage on screen, ips linux image shows nothing only backlight.

I must see how i can read the flash, in circuit or desolder it and try to solder pins on or something, as i do not have such adapter.

@Situ

a friend of mine brought an FC3000 v2 IPS, can i use the dump image you gave me to dump his stock rom.
he wants linux on his too, but i want to backup his stock rom first for safety reasons.

What? You mean fba?   I was playing a game and wanted load another rom, but "I" menu key did nothing.

I compiled the kernel source from you via wget from your github

I know somebody already mentioned that the I(Menu) key us not working in FBA, is there a solution or source code?

hahaha 😊 
PS: it is done! happy downloading

@司徒

Noise is gone when setting backlight to 100.
Unmodded= you provided me the code for "dac.c" to poweron the amp chip, but only what happend was that the green led lights up.
So i bypassed the shutdown pin from the sound amplifier to 3.3v, cause uboot did not poweron the amplifier.
I got it working in "dac.c", green led on, and amp on.
So, everyone can use our linux version without modify the hardware.

I want to dump my OS like your linux images...

Partition 1 - 32MB empty (uboot)
Partition 2 - 256MB fat32 FC3000 (rootfs,mininit)
Partition 3 - ~2GB fat32 OD (folders,configs,menu etc)

All in one .img file.

The user has to expand Partition 3 after flashing on sdcard to the rest space

@司徒

thank you, i will add variant 3 for fc3000_old

@司徒

[A1] no problem, not important

[A2] "I" now working without modification  "I_MENU    = ((32 * 0) + 3);"

[A3] ahhh, that's logical then

[A4] till now i do not knew how to set the brightness, now after configure the system to 100% brightness, all went fine

[A5] Danke<3

[A6] just came in my head, only an idea

I thank you so much for your help, my FC3000 would be complete dump without you. i am happy to work with you, was a lot of fun.
i wil try to optimice the modified code, maybe add a new variant (fc3000_old).
i will even try to enable the snd_shutdown pin via gpio, so everyone who needs this firmware can use it without hardware modification.
can you tell me how i can add a new variant?

i saw in an other forum that someone got the .wst files decrypted, do you have the tool or can you maybe ask the user for his tool please (User: aoa)?
https://boards.dingoonity.org/other-game-systems/fc3000-linux-porting-from-scratch/100/

@Situ

All buttons but I(Menu) working now.
Since my I button connects to PA3 i think this pin is not in input mode!?
PS: when reading ((32 *4) + 6) system does not boot when Green LED is on via DAC.C (your attempt to enable sound but only did the Green LED Light up)

AND....  the coil noise is gone when setting backlight to 100%

PPS: Thats not me in the twitch stream

@司徒

L1/R1 are electrical connected with A/B, i must cut the trace and connect it to any free pin on the mcu if possible.
atleast i want to get A,B,X,Y,START,SELECT,I working.
the whinig noise in the speaker comes from the LCD, when i press I the noise is little lower.

i will take photos from the pcb for you of course.

yes, multimeter and my eyes with magnification glas
The line from start and select beeps when I check the negative pole of the battery

START -> PE4
SELECT -> PE3

@Situ

Tracing my buttons done!
L1 = A
R1 = B

i tried this, but results are not as expected (UP/DOWN/LEFT/RIGHT are working)

suniv-keypad.c in function static int __init kbd_init(void)

else if(suniv_variant == 2) {

        I_UP    = ((32 * 5) + 0);
        I_DOWN  = ((32 * 5) + 5);
        I_LEFT  = ((32 * 5) + 4);
        I_RIGHT = ((32 * 4) + 2);
        I_A     = ((32 * 4) + 7);       //PE7
        I_B     = ((32 * 4) + 5);       //PE5
        I_X     = ((32 * 4) + 9);       //PE9
        I_Y     = ((32 * 4) + 8);       //PE8
        I_L1    = ((32 * 4) + 7);       //PE7 (L1 = A)
        I_R1    = ((32 * 4) + 5);       //PE5 (R1 = B)

        I_L2    = ((32 * 4) + 10);
        I_R2    = ((32 * 4) + 7);
...

@Situ

yes, my board has lot differences, my UART1 RX pad from your picture is GND on my board.
seems my CPU is a chinese knockoff or much different version

I can't thank you enough for helping me <3

@Situ

I checked the sound chip (4890s), shutdown pin = 0-1.2v (low or floating), traced the pin to cpu (see pictures)

Hopefully my cpu is f1c100s pin compatible (i can not find the PAx pins)

@司徒

No idea how I got there, but the menu looked something like this (every time after booting)

@司徒

thank you very much, you are the best <3

@司徒

Got the colors fixed now👍

@Situ

can you convert the lcd_wr assembler routine to c#?   i am not able to convert assembler to c#.
i think i have to modify sunivfb.c and lcdc.h atleast

i will try the reset routine by my self, it is hard for me either, hahaha

Thank you so much! what do you think, could you do something on the linux kernel now?

@司徒

again, nothing , all white / only backlight

ps: i did it!!! took your test_6 with the "snow" and added command 0x22 at the end of init
(cmd 0x22, write sram, hx8347)
main.s.txt

pps: test_7.s works also, added ldr r0, =0x22(bl lcd_cmd) at the end of init

@hox

thank you very much

Unfortunately I don't have a logic analyzer. it was the same for me, I read that I can make my v1 a v2, then I thought that I would start a dump program, but unfortunately it was an ips flasher. nothing is possible without stock old v1. apart from what Situ and I try, we can't do anything else for the device. unless someone has the same old v1 and would dump the rom

keep your device if you still have it, maybe we can run situ's linux on them later

@司徒

result: colored "snow/noise"

thank you very much, unfortunately there is no information or downloads on their site, I wrote via the contact link, let's see.

@Situ

if R and B are swapped, shouldn't it just be wrong colors?
i try your test files now

@Situ

Here are some photos from the display and connector, maybe you can use it

@Situ

was able now to compile it. gcc version 8 and higher has a problem with null pointer strings, i had to change 2 lines in gdbusmessage.c and gdbusauth.c

why do you think it's not hx8347?

thanks <3,you are a master, i will try the images now

@Situ

ps: i do not hear any sound when booting linux

I don't know. Maybe an older V1 version. As my mcu is an M800 and not M900.
SPI flash is on the other side

@Situ

fc3000 starts with a white screen now. is that right?

@Hox

Yes, I saw it, that's why I didn't even ask you.  I accidentally bricked mine too.  I thought I started a dump program, but then it was an ips flasher.  I hope that I can at least get linux running on it through situ before I throw it away

thanks for the informations

@Situ

A1: Thank you very much, maybe i can find someone with the same model, a dump tool would be handy.

A2: my device has an tft display i think (T2812-M106-24C-7D, maybe an HX8347 driver) cpu is M800.

i would be very grateful if you would help me there at least to have linux on it
thank you

i have the same model, my cpu is M800 and i bricked mine, i need help, the stock v1 rom or how i can port the linux over
