TF卡启动

一 软硬件环境​

1.1 硬件环境​

以RD_AD100_EVB_V1.0开发板为例, 需更改启动方式为msc0（tf卡对应控制器）

1

1.2 软件环境​

使用配置ad100_mmc0_5.10_defconfig编译

bhu@bhu-PC:~/ad100/build$ make clean                   //第一次编译不需要make clean
bhu@bhu-PC:~/ad100/build$ make ad100_mmc0_5.10_defconfig
bhu@bhu-PC:~/ad100/build$ make

编译后生成固件如下：

bhu@bhu-PC:~/ad100/build/output$  ls -l 
-rw-r--r-- 1 bhu  bhu   4325376 4月  11 10:19 rootfs.squashfs
-rw-r--r-- 1 bhu  bhu    215164 4月  11 10:19 u-boot-with-spl-mbr-gpt.bin
-rw-r--r-- 1 bhu  bhu   4972608 4月  11 10:19 xImage

二 TF卡写入镜像​

offset需要与分区表一致, 位于bootloader/uboot-x2000/board/ingenic/ad100_base/partitions.tab

property:
    disk_size = 3728m
    gpt_header_lba = 512
    custom_signature = 0

partition:
    #name     =  start,   size, fstype
    xboot     =     0m,     1m,
    kernel    =     1m,     8m, EMPTY
    dtb       =     9m,     1m, EMPTY
    rootfs    =     10m,    100m, LINUX_FS
    kernel2   =    110m,    8m, EMPTY
    dtb2      =    118m,    1m, EMPTY
    rootfs2   =    119m,   100m, LINUX_FS
    ota       =    219m,    1m, EMPTY
    userdata  =    220m,   3508m, LINUX_FS

#fstype could be: LINUX_FS, FAT_FS, EMPTY

使用读卡器将sd卡插入电脑, 使用 ls /dev/sd* 命令查看所有的磁盘设备, 找到sd卡对应设备路径

sudo dd if=/dev/zero of=/dev/sdb bs=4M status=progress         #格式化sd卡设备
sync
#重新插拔sd卡确认是否只有/dev/sdb节点, 没有/dev/sdb1 .....  
sudo dd if=u-boot-with-spl-mbr-gpt.bin of=/dev/sdb
sudo dd if=xImage of=/dev/sdb bs=512 seek=2048      #与分区表一致, offset 1MB
sudo dd if=rootfs.squashfs of=/dev/sdb bs=512 seek=20480  #与分区表一致, offset 10MB
sync

三 卡启动​

将卡插入开发板, 上电查看串口打印, 可以看见系统正常启动
