Hi Kukjin, Thank you for your review. I was confused a little bit about bootargs what is better removing or including it in the board file, obviously I saw error message failing mount the root file system if I remove bootargs from board file and with default bootargs from u-boot. What I thought is passing bootargs from boot-loader would be better to give more options like boot device and partition setup to the developers. If board file has fixed bootargs, then DTS file has to be updated whenever boot partition is changed or arguments need to be changed. And bootargs and other boot configuration could be set up from u-boot itself with certain script as well, I believe that this is much easier and comfortable rather than changing DTS file. We also can start the hardware with initramfs with default bootargs like "boot=/dev/ram0 rw ramdisk=8192..." and mount the expected boot partition for rootfs, anyhow real boot media has to be specified in bootargs as well. Thanks and any advice will be welcomed a lot. Best regrds, Dongjin.
