Hello,

I’m trying to write into uboot env-var using fw_setenv in script.
but I’m facing this problem

Write error on /dev/mmcblk0boot0: Operation not permitted
Error: can't write fw_env to flash

Do i miss something?

By default in Linux /dev/mmcblk0boot0 is read only.

Have a look at the following script which in our demo images to unlocks mmcblk0boot0 before writing to the U-Boot environment.

Ok I know how to solve this problem.
