Dear All,

I able to flash uboot binary (imx-boot-) using uuu tool for IMX8MN evk board. But, I unable to do it from kernel using dd command

$ dd if=imx-boot of=/dev/mmcblk2 bs=1k seek=33

$ sync

Board: IMX8MN-EVK

EMMC Chip: mmcblk2

Will you please guide me to flash u-boot binary from kernel for IMX8MNano EVK ?

Hi vinothkumars,

What error are you getting when you do this?

Also, you should take a look at the Linux user manual, chapter 4.3.2, It will be very helpful.

Regards,

Israel H.
