系统更新方法（System update method）​

Device Routes:

DeviceNode
eMMC/dev/mmcblk2
SD/dev/mmcblk1
QSPI/dev/mtd0

RSB-3730 SW1 boot select

For example: SD test

dd if=/dev/urandom of=data bs=1 count=1024
dd if=/dev/mmcblk1 of=backup bs=1 count=1024 skip=4096
dd if=data of=/dev/mmcblk1 bs=1 seek=4096
dd if=/dev/mmcblk1 of=data1 bs=1 count=1024 skip=4096
diff data data1
dd if=backup of=/dev/mmcblk1 bs=1 seek=4096

Install the System from SD Card

  1. Copy imx-image-full-imx8mmrsb3730a2-xxxxxx.rootfs.sdcard to your desktop (use Ubuntu OS).
  2. Insert SD card to PC.
  3. Make a bootable SD card (e.g. node is /dev/sdv):
umount /dev/sdv*
dd if=./imx-image-full-imx8mmrsb3730a2-xxxx.rootfs.sdcard of=/dev/sdv bs=1M
sync
  1. Copy imx-image-full-imx8mmrsb3730a2-xxxxxx.rootfs.sdcard to USB disk.
  2. Insert USB disk and SD card, boot from SD card by changing SW1 to 1-2 ON.
  3. Enter USB disk folder, flash to eMMC:
cd /run/media/sda1/
umount /dev/mmcblk2*
dd if=./imx-image-full-imx8mmrsb3730a2-xxxx.rootfs.sdcard of=/dev/mmcblk2 bs=1M
sync
