哇酷小二说：

disabled other network card on PC？

no but I connected my raspberrypi zero using the same way by assigning static ip and it worked for me.
so I assume the problem in the mangoPi not the pc
I also tried to connect my mangoPi to linux pc and assigning static ip but no change.

hello there
I'm trying to activate otg usb as RNDIS to communicate with MangoPi using ssh
I'm using the following buildroot linux image
buildroot-mangopi-r

by default the otg is working as storage device , I did the following steps to activate otg as RNDIS to work with ssh

 make menuconfig

Target packages --->
	Networking application --->
		[*] openssh

Target packages --->
	Package managers --->
		[*] opkg
		[*] gnupg support

Target packages --->
	Text editors and viewers
		[*] nano
		[*] optimize for size (NEW)

then type

make linux-menuconfig

device dervicers -->
	[*] USB support --->
		<*> USB Gadget support --->
			<*> USB Gadget precomposed configurations
				[*] RNDIS support (NEW)
				[*] Ethernet Emulation Model (EEM) support

after booting linux

check the usb RNDIS is working by

 ip a

now, change the file the interfaces file in /etc/network/interfaces

 nano /etc/network/interfaces

auto usb0 
#I tried also to comment the following line but it doesn't work.
allow-hotplug usb0 
# The address, gateway and netmask are necessary. 
iface usb0 inet static 
    address 10.42.0.2 
    netmask 255.255.255.252
    dns-search mangopi.edu
    dns-namesevers 8.8.8.8 128.83.185.40, 128.83.185.41

the total steps

I set a static ip in windows11

when trying to connect using ssh, I got that!

also when trying

 ping 10.42.0.2

I got

 Request timed out.

What's the problem?

could someone tell me .. is the cross compiler I used is right or there's an official cross compiler for f1c200s ??

I build the image here
https://github.com/mangopi-sbc/buildroot-mangopi-r

the build system I used the default buildroot toolchain
buildroot.jpeg bbcode buildroot

I compiled the spidev_test.c with cross compiler: arm-linux-gnueabi-gcc
I tried another program using this cross compiler and it worked for me

Hello there,
I'm working on MangoPi-r3 based on F1C200S, I'm trying to communicate with TFT st7735r using spidev1.0
I wrote a code that working on RaspberryPi Zero and worked with the tft , but when I tried it on F1C200S it doesn't work , I think the problem in the spi driver
I also tried to run the spidev_test.c
https://github.com/rm-hull/spidev-test/blob/master/spidev_test.c

I was able to compile it but when trying to run it on F1C200S I got a strange message
/usr/lib/libc.so.6: version `GLIBC_2.33' not found

any help?
