New Coldfire Linux BSP for MCF5484/85 EVB boards

[jkimble]

I've been working with a custom board that is a spin off of the MCF5485EVB and I've had the old BSP working (with many custom drivers) for some time. Most of my custom drivers already exist in the new BSP and I'd like to get on the later kernel.

I've customized Colilo for my board. Mostly differences in SDRAM and FLASH (more of both and different FLASH). I would like to stick with Colilo just to save the time of learning u-Boot right now. How can I boot this new kernel from Colilo (or can I)? I tried tftp'ing vmlinux.bin and "g 2000" but got not response (expected).

Can anyone tell me how to do this?

I think that the only thing you should have to change is the START_OFFSET in arch/m68k/coldfire/vmlinux-cf.lds

I modified mine from

#DEFINE START_OFFSET 0x00020000
 
to

#DEFINE START_OFFSET 0x00001000

and everything started booting from there...

Tried that out. The console shows one line of garbage (similar to a console serial baud rate mismatch) and quits. Nothing after that and no response to console activity like I would expect if it were simply a console speed thing.

Anything else I'm missing?

The default baudrate for the new kernel is 115K.

That worked! Beautiful....

Thanks a lot!

I'll give that a try. Thanks!
