Well, bootcmd is what gets run by default, and it differs quite a bit on the working system - there it specifies the address of an nfs server.
You could try to run these things manually in parts - first the dhcp, then the setenv and then the bootm command. Make sure that the bootargs contain the address and path for your nfs filesystem and your root device isn't any of the mtblock devices. These commands aren't particular to a roach, but to uboot in general and should be documented online. regards marc On Fri, May 11, 2018 at 10:02 AM, Bela Dixit <dixitb...@gmail.com> wrote: > Thanks Devid and Marc. > Working ROACH2 not giving "bad CRC" warning. > I tried with printenv command to check environment variable there is > difference between working and non-working board.
