使用最新的 u-boot: 编译 V3s 2019 版本的 u-boot

(文件已经在一楼附件内)

2019-05-08 更新:
---------------------------------

mkimage -C none -A arm -T script -d boot.cmd boot.scr

用这个命令生成 scr 文件

晕哥 · 2019-04-25 16:59:50

参考: https://whycan.cn/t_444.html

sunxi-fel 需要修改fel.c

#define SPL_MAX_VERSION 2 /* maximum supported version */

改为 3:

#define SPL_MAX_VERSION 3 /* maximum supported version */

然后重新编译, 否则 sunxi-fel 不会解析传递 scr 环境变量参数给 u-boot.

请教一下晕哥 f1c100s initramfs制作是直接在buildroot中file system勾选 cpio 以及uboot image，然后是在buildroot system configure里面在/dev management里面要选上mdev，是吗？

这种和引用的这种用命令的方式有什么区别吗？因为一开始不知道，按照命令来做f1c100s的文件系统结果是无法挂载。

晕哥 · 2019-07-10 21:00:09

忘记是否要勾选了, 你自己试一试.

晕哥你好，如果我想自己编译用于USB直接启动Linux的uboot（2019.10版本），需要修改哪些内容。我看启动命令已经在SCR文件指定了。

晕哥，我用buildroot-2018.02.10编译出rootfs再转换成rootfs.cpio.gz.uImage，替代 v3s_s3_fel_autorun_linux_uart0_pb8_pb9_201905018_spinand_OK.7z里面的rootfs.cpio.gz.uImage，但是内核启动完后就卡住了，用你原来的就可以正常使用。使用的是华嵌的S3核心板。
制作initramfs时buildroot需要什么特殊配置么。

零、目的
华嵌的S3核心板烧系统到sdnand
使用晕哥的 <<荔枝派zero/小智极客S3/V3s使用sunxi-fel 借 u-boot 启动 Linux系统, 无需 spi flash / TF 卡 by 晕哥>>，直接挂SD_NAND为U盘然后烧录

一、硬件
华嵌的S3核心板，没有底板，直接核心板上飞线引出5v GND USB+ USB- 调试口UART0
这块核心板区别于其他开发板 SD NAND是挂在在mmc2上的(PC口sdc2)

二、SDK及固件
华嵌群网盘里提供的uboot(就是 git clone https://github.com/Lichee-Pi/u-boot.git -b v3s-spi-experimental 基础上修改) 及5.1.0的内核

晕哥帖子里的 v3s_s3_fel_autorun_linux_uart0_pb8_pb9_201905018_spinand_OK.7z

三、分析说明
3.1使用v3s_s3_fel_autorun_linux_uart0_pb8_pb9_201905018_spinand_OK.7z
3.1.1完整下载
解压完后利用Run_S3_XiaoZhi.bat里面的命令来下载启动系统，这里及以下我全都是在ubuntu中进行的所以直接用sunxi-tools源码编译后sunxi-fel命令来下载的

sudo ../sunxi-tools/sunxi-fel -p uboot u-boot-sunxi-with-spl.bin.S3 write 0x41000000 zImage write 0x41800000 sun8i-v3s-licheepi-zero-dock.dtb.PG9 write 0x41900000 boot_fel_initrd.scr write 0x41A00000 rootfs.cpio.gz.uImage

串口上的启动信息如下(截取重要的部分)：

	modprobe g_mass_storage file=/dev/mtdblock0 removable=1
	#

我们看到登录进入后没有加载mmc2驱动识别sdnand，这样自己手动加载g_mass_storage重指定file也没用

3.1.2只下载uboot来看一下env

	Environment size: 4054/32764 bytes
	=>

注意这里的bootcmd=run distro_bootcmd 以及没有设定bootargs
然后再看看里面的scriptaddr、fdt_addr_r等几个地址，理解一下boot_fel_initrd.cmd和Run_S3_XiaoZhi.bat这里面几个地址

3.2使用华嵌提供的SDK
v3s_s3_fel_autorun_linux_uart0_pb8_pb9_201905018_spinand_OK.7z中的boot_fel_initrd.cmd中会设定bootargs,
所以首先将华嵌给的uboot中sun8i.h里面#define CONFIG_BOOTARGS "console=ttyS0,115200 panic=5 rootwait root=/dev/mmcblk2p2 rw earlyprintk"这句屏蔽
顺便再理解一下uboot的修改记录：dts里面的关闭spi0打开mmc2并且配好mmc2的管脚、配置文件中配上CONFIG_MMC_SUNXI_SLOT_EXTRA=2

利用SDK中编出u-boot-sunxi-with-spl.bin、sun8i-s3-hqembed-050ips.dtb、zImage

结合楼上提问buildroot编译出来的rootfs用不了，这里使用v3s_s3_fel_autorun_linux_uart0_pb8_pb9_201905018_spinand_OK.7z中的
rootfs.cpio.gz.uImage再加上里面的boot_fel_initrd.scr

这样就拼凑完了要用的镜像文件，然后同样的下载

sudo ../sunxi-tools/sunxi-fel -p uboot u-boot-sunxi-with-spl.bin write 0x41000000 zImage write 0x41800000 sun8i-s3-hqembed-050ips.dtb write 0x41900000 boot_fel_initrd.scr write 0x41A00000 rootfs.cpio.gz.uImage

看一下启动信息：

	...
	starting USB...
	No controllers found
	Hit any key to stop autoboot:  0 
	switch to partitions #0, OK
	mmc1 is current device
	MMC: no card present
	** Bad device mmc 0 **
	MMC: no card present
	** Bad device mmc 0 **
	## Flattened Device Tree blob at 41800000
	   Booting using the fdt blob at 0x41800000
	   Loading Device Tree to 42df9000, end 42dff707 ... OK

	Starting kernel ...
	.....
	[    0.000000] Kernel command line: console=ttyS0,115200 panic=5 rootwait root=/dev/ram0 rdinit=/linuxrc rw earlyprintk
	....
	[    1.599704] cfg80211: failed to load regulatory.db
	[    1.605126] Waiting for root device /dev/ram0...
	[    1.617593] mmc2: host does not support reading read-only switch, assuming write-enable
	[    1.625824] mmc2: new high speed SD card at address 00c3
	[    1.632978] mmcblk2: mmc2:00c3 E1601 121 MiB 
	[    1.639478]  mmcblk2: p1

我们可以看到bootargs传的对，内核起来后mmc2上也认出了sdnand, 但是卡在了Waiting for root device /dev/ram0...上进行不下去

四、修改
4.1修改uboot

此时对比一下3.1与3.2中uboot引导内核时候的打印信息及env，需要修改bootcmd
将华嵌给的uboot中sun8i.h里面

#define CONFIG_BOOTCOMMAND "mmc dev 1;fatload mmc 0 $fdt_addr_r $fdtfile;fatload mmc 0 $kernel_addr_r zImage;bootz $kernel_addr_r - $fdt_addr_r"

修改为

#define CONFIG_BOOTCOMMAND "run distro_bootcmd"

别忘了将uboot中sun8i.h里面#define CONFIG_BOOTARGS "console=ttyS0,115200 panic=5 rootwait root=/dev/mmcblk2p2 rw earlyprintk"这句屏蔽

然后重编出u-boot-sunxi-with-spl.bin，
再配上3.2中编出的sun8i-s3-hqembed-050ips.dtb、zImage
v3s_s3_fel_autorun_linux_uart0_pb8_pb9_201905018_spinand_OK.7z中的rootfs.cpio.gz.uImage与boot_fel_initrd.scr

重新下载运行，看到能正常启动和登录，但有两个问题

mmc2上没有挂载sdnand ---> 解决见4.2
modprobe: can't change directory to '5.1.0': No such file or directory 内核版本与rootfs中里面的ko不匹配---> 解决见4.3

4.2挂载sdnand
看一下3.2中当
CONFIG_BOOTCOMMAND "mmc dev 1;fatload mmc 0 $fdt_addr_r $fdtfile;fatload mmc 0 $kernel_addr_r zImage;bootz $kernel_addr_r - $fdt_addr_r"
时能够正常挂载sdnand

所以修改boot_fel_initrd.cmd，在bootz 0x41000000 0x41A00000 0x41800000前一行mmc dev 1
然后再mkimage -C none -A arm -T script -d boot_fel_initrd.cmd boot_fel_initrd.cmd.scr 出新的scrpit文件

4.3重新制作rootfs.cpio.gz.uImage
用晕哥的v3s_s3_fel_autorun_linux_uart0_pb8_pb9_201905018_spinand_OK.7z中的rootfs.cpio.gz.uImage来逆向

rootfs.cpio.gz.uImage正向打包的是这样
cd /opt/buildroot-2018.08.2/output/target
find . | cpio -o -Hnewc |gzip -9 > ../rootfs.cpio.gz
mkimage -A arm -T ramdisk -C none -n uInitrd -d ../rootfs.cpio.gz ../rootfs.cpio.gz.uImage
逆向:
mkimage其实就是在原来的文件头上加了0x40个字节的特定头让uboot能引导识别，
所以先把rootfs.cpio.gz.uImage重命名成bin文件，用随便能编辑bin文件的工具打开，去掉头上的0x40长度的头，再重名文件成rootfs.cpio.gz
然后gunzip rootfs.cpio.gz出来rootfs.cpio文件，
再sudo cpio -idmv <rootfs.cpio出来rootfs所有文件
对这个rootfs补上/dev/concloe /dev/null
sudo mknod -m 666 console c 5 1
sudo mknod -m 666 null c 1 3
这样就提出来了一个完整的rootfs

替换内核模块：
删除上面rootfs/lib/modules里面原来的两个内核文件夹，把自己编译的华嵌5.1.0内核模块替换过来

先屏蔽/etc/init.d/S90mmc0_as_udisk.sh 里面的驱动加载，方便后面调试
再正向打包生成新的rootfs.cpio.gz.uImage

4.4usb模式
使用上面
4.1的u-boot-sunxi-with-spl.bin、
4.2中的boot_fel_initrd.cmd.scr、
4.3中的rootfs.cpio.gz.uImage、
3.2中华嵌5.1.0内核源码编出来的sun8i-s3-hqembed-050ips.dtb与zImage

下载运行，能识别到sdnand,挂成了/dev/mmcblk2,然后手动
modprobe g_mass_storage file=/dev/mmcblk2 removable=1
但是ubuntu电脑上没有任何反应，
看一下内核sun8i-s3-hqembed-050ips.dts中
&usb_otg {
//dr_mode = "otg";
dr_mode = "host";
//dr_mode = "peripheral";
status = "okay";
};
我们这里需要usb device模式，将其修改为
&usb_otg {
//dr_mode = "otg";
//dr_mode = "host";
dr_mode = "peripheral";
status = "okay";
};

再重新下载，运行，至此能够在电脑上显示sdnand盘了。

下面就可以用命令来分区和烧写sdnand了

JinC · 2020-03-12 17:34:21

回复一下前面buildroot编出来转rootfs.cpio.gz.uImage不能启动的问题：
这里重新配一下buildroot，里面Filesystem images ---> 选中cpio the root filesystem (for use as an initial RAM filesystem) 并且 Compression method 选择(gzip)
重新编译完后在buildroot的 out/images/目录下直接有rootfs.cpio.gz
然后用这个文件来加头 mkimage -A arm -T ramdisk -C none -n uInitrd -d ../rootfs.cpio.gz ../rootfs.cpio.gz.uImage
这样就能正常挂了。
去output/target目录里面手动打cpio再加头出来的rootfs.cpio.gz.uImage没发启动起来。

五、烧写sdnand
接楼上接着进行分区和烧写sdnand
5.0看一下sdnand的信息
我没找到sdnand的数据手册，进入uboot看一下mmcinfo,顺便把mmc擦一下
同3.1.2中方法一样只运行uboot
sudo ../sunxi-tools/sunxi-fel -p uboot u-boot-sunxi-with-spl.bin.S3 write
进入uboot后
=> mmc list
SUNXI SD/MMC: 1
SUNXI SD/MMC: 0 (SD)
=> mmc dev 0
switch to partitions #0, OK
mmc0 is current device
=>
=> mmcinfo
Device: SUNXI SD/MMC
Manufacturer ID: d5
OEM: 5344
Name: E1601
Tran Speed: 50000000

SD version 1.10
High Capacity: No
Capacity: 120.9 MiB
Bus Width: 1-bit
Erase Group Size: 512 Bytes
=> mmc erase 0 40000

5.1建分区
按4.4中下载运行全部镜像
我这里是在开发板上直接用命令进行分区，这个pc上fdisk分区有点区别

# fdisk  /dev/mmcblk2
The number of cylinders for this disk is set to 3868.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
   (e.g., DOS FDISK, OS/2 FDISK)

Command (m for help): p

说明一下这里在开发板子中直接使用命令见分区与在宿主机上fdsik是有差距的．
分区说明：
最头上1M用来放uboot,由于这款SDNAND的sector szie是512字节，所以第一个分区前预留1Mbyte/512byte=2048个sector

然后第一个分区定为8M,这样他的结束就是2048+8Mbyte/512byte -1 = 18431，
这里我用+8M没成功，因为开发板上的fdisk貌似是绝对偏移，不是相对的

第二个分区就是剩下的所有sector,也就是从18432开始到结束，

这是时候就能看到ubuntu下能够挂出两个盘 boot 与root
在ubuntun电脑上

$ sudo dd if=u-boot-sunxi-with-spl.bin of=/dev/sdc bs=1k seek=8

$ cp zImage sun8i-s3-hqembed.dtb /media/pc189/boot/
$ sudo tar xvf rootfs.tar  -C /media/pc189/root/

注意这里的u-boot-sunxi-with-spl.bin为重新编译的bootcmd为使用mmc，bootargs挂载/dev/mmcblk2p2为root 的uboot

至此烧完重启设备正常

老大，用自己的 rootfs，不管是用您给的方法打包成 rootfs.cpio.gz.uimage，还是用上面网友提到的自动生成 rootfs.cpio.gz然后手动打包，都是启动后出现 "Start kernel"，然后就卡住了。

能不能提供一下 buildroot 的信息，比如版本和 .config文件等，谢谢！

试过，不行。这个选项可以自动生成 rootfs.cpio和 rootfs.cpio.gz（选 gzip压缩时）

rootfs.cpio.gz.uImage 是18M的样子，用过几个，都不行。比如“入坑指南”里面的 2017.08，“一键生成 spi-nor，自动启动 AnalogClock”里面的 2018.08，几个版本都一样，都是 Starting Kernel，然后就没有了。

和buildroot版本没有关系, 应该是尺寸和文件格式问题。

文件系统不完整吧，貌似有些设备文件没有找到?

Initial RAM silesystem and RAM disk这项关了试试

jianke512 · 2022-03-08 16:55:07

感谢分享，收藏一下,等案子开始了，就有用了

xiang · 2022-03-20 22:50:34

顶啊，以后调试不用卡了

sun_sky1 · 2022-03-29 00:08:19

这样就方便很多了，不用来回换卡。可以提高测试时的效率

caglarpasli · 2022-05-26 01:11:16

I will use V3S in my new design. But does it boot from EMMC(SDC1)

SDC1不能boot，
只有SDC0,SDC2可以。

V3x 能支持就好，要自己做

老大是这个源码?直接编译还是要修改哪里

我使用的f1c200的板子，一直按照启动命令来测试，但是一直没有反应。后来发现内存地址0x40000000的地方，存不住数据，只能在0x80000000的位置。
