Hello All,

 

I am using sabre-sd board and imx6q yocto bsp. I am trying to set environment from user space. I have generated fw_printenv and fw_setenv. fw_printenv is working perfectly.

 

I can able to set environment using fw_setenv and i can able to view it using fw_printenv from userspace.

But my problem is that, if i reboot the board I cant get the changed environments done from user space.

 

I have tried this commands also,

 

echo 0 > /sys/block/mmcblk2/force_ro

echo 1 > /sys/block/mmcblk2/force_ro

 

I have enclosed my patch files also.

Need Help to resolve this issue.

Thank you.
