IPL, IPL_CUST, UBOOT的烧录地址和kenerl log刚好能对应起来.

现在问题来了, 为什么 IPL, IPL_CUST, UBOOT 这三个都有两份一模一样的?

是备份? 考虑 NAND 不稳定?

直接用md5sum获取分区的校验码, 果然备份分区与原分区数据一模一样.

好奇, 怎么判断原分区数据出错呢?

大概知道为什么第一个分区不是地址0 开始了, 因为前面还有一个 cis.bin

解压 IDO-SSD20X\开发板\IDO-SBC2D07\images\202_256M\images_7open_202_256M.tar.bz2 (我这个板子芯片是江波龙的FS35ND02G 2Gb SPI NAND)

得到 SigmastarUpgrade.bin

拷贝到U盘,

插入到启明云端7寸紫色开发板

重启会自动刷固件.

或者启动的时候, 进入串口终端按住回车键不放, 进入终端, 插入有SigmastarUpgrade.bin文件的U盘, 然后输入 usbstar 命令也可以自动刷固件

这是刷固件的log:

自己手动做了一个 USB刷机固件 SigmastarUpgrade.bin

结果把系统搞死了, 是不是一定要官方那个 debug 刷机硬件才行? 还有救吗?

导出带oob的ubi分区数据到U盘根目录 20x_ubi.bin

echo UDISK > /dev/udisk_4g;mkdir /mnt/udisk -p;mount /dev/sda /mnt/udisk

nanddump -o -b -f /mnt/udisk/20x_ubi.bin /dev/mtd11

挂载到ubuntu:

sudo modprobe nandsim first_id_byte=0xad second_id_byte=0xda third_id_byte=0x10 fourth_id_byte=0x95
sudo dd if=/mnt/hgfs/D/20x_ubi.bin of=/dev/mtd0

sudo mkdir /mnt/customer   -p;sudo mount -t ubifs ubi0:miservice /mnt/customer
sudo mkdir /mnt/appconfigs -p;sudo mount -t ubifs ubi0:miservice /mnt/appconfigs

目录显示正常:

这是我从 /dev/mtd11 读出来带oob数据的文件: 20x_ubi.7z

参考:

请问我在 ubuntu 可以模拟挂载ubi 文件系统吗?

这个启动脚本的大意是，如果KERNEL分区处的kernel启动失败, 那么就读备胎分区 RECOVERY 继续启动，可是KERNEL启动都到了LINUX了，如果失败，UBOOT真还能继续接管吗？我表示怀疑。

SigmaStarStudy · 2021-02-25 17:24:03

楼上问题我咨询过启明工程师了，

uboot使用bootm加载 uImage文件， uImage比zImage 多出一个 0x40 大小的文件头，记录了这个映像文件的类型、加载位置、生成时间、大小, CRC校验等信息, 如果读出来一个字节有问题, 必然CRC结果不对，bootm出错，然后uboot命令行继续接管。

这样实现了备份分区继续引导的任务。

用网线连接，手动可以敲以上命令刷新rootfs文件系统

mkdir /mnt/ubifs -p;mount -t ubifs /dev/ubi0_0 /mnt/ubifs

进入linux可以用这个命令手动挂载文件系统

mkdir /mnt/ubifs -p;mount -t ubifs ubi0:rootfs /mnt/ubifs

也可以用卷标(volume)的形式挂载

比实际实际创建的空间大一点, 应该是把oob数据都读出来了。

buildroot ubi文件系统镜像 rootfs.ubifs 输出配置如上图所示.

然后通过这个命令在 u-boot 写入:

ubi part UBI;tftp 0x21000000 rootfs.ubifs;    ubi write 0x21000000 rootfs ${filesize}

tftp下载 rootfs.ubifs 并写入 flash, 启动后基本正常，可以进入命令行。

建立 /etc/init.d/S00init

#!/bin/sh
export PATH=/bin:/sbin:/usr/bin:/usr/sbin
export LD_LIBRARY_PATH=/lib
mkdir -p /dev/pts
ulimit -c unlimited
export PATH=$PATH:/config
export TERMINFO=/config/terminfo
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/config/lib
mkdir -p /dev/pts
mount -t sysfs none /sys
mount -t tmpfs mdev /dev
mount -t debugfs none /sys/kernel/debug/
mdev -s
mkdir -p /var/lock

mkdir /config /customer /appconfigs -p

mount -t ubifs ubi0:miservice /config
mount -t ubifs ubi0:customer /customer
mount -t ubifs ubi0:appconfigs /appconfigs

mkdir -p /dev/pts
mount -t devpts devpts /dev/pts
busybox telnetd&

if [ -e /etc/core.sh ]; then
    echo "|/etc/core.sh %p" > /proc/sys/kernel/core_pattern
chmod 777 /etc/core.sh
fi;

if [ -e /customer/demo.sh ]; then
    /customer/demo.sh
fi;

修改执行属性:
chmod +x /etc/init.d/S00init

这样开机可以加载所有驱动了

花屏测试OK:
cat /dev/urandom > /dev/fb0
