Hi all, I'm working with a board with a MPC8548 processor. I built the uboot (version 1.3.0), the DTS file (myboard.dtb) and a kernel 2.6.21 . When I try to boot the kernel via NFS I have some exception mode when parsing the kernel parameters. Specifically I obtained an error during the parsing of "console" parameter. My host computer is connected to the board via console using a standard 8250 port.
I append the log in this post.
Has anyone any suggestion?
Thanks in advance for the reply.
