I am using i.MX 6 SOM board and bulid the image for it using Yocto(as per instructions in i.MX Yocto Project User's Guide).
When tried to customize U-Boot using "bitbake u-boot -c menuconfig", its giving error like "do_menuconfig does not exist for target u-boot-imx".
And I found that using devshell, u-boot can be customized. But procedure for customization and rebuilding image after that is not clear.
Please help me with detailed procedure for u-boot customization using devshell.
