HW: IMX8QXP EVK

I had flash flash.bin file to /dev/mmcblk0boot0 and /dev/mmcblk0boot1

I can run " mmc bootpart enable x 1 /dev/mmcblk0" to set system start from /dev/mmcblk0boot0 or /dev/mmcblk0boot1.

during u-boot starting, how to konw which partition is using? /dev/mmcblk0boot0 or /dev/mmcblk0boot1?

Hi @wang12zhe

You can try "mmc partconf <dev>" in uboot.

Best regards

Harvey

你好，您知道/dev/mmcblk0和/dev/mmcblk1在emmc的地址吗，我可以uboot命令行下将uboot进行在线更新吗

Unfortunately, like you said the method I did not succeed, I read the IMX_LINUX_USERS_GUIDE.pdf manual before, I tried the mmc partition structure on page 9, and did not find the uboot that I downloaded using uuu, I even rummaged from 0x0 to 0xa00000 and did not find it
