Hello, I am cuurently trying to boot up the linux kernel using ppcboot 1.16 and the 2.4 kernel with only smc1 uart support as a start on an MPC860 FADS derived board. So far I have: - ppcboot running great - tftpboot graps my kernel puts in RAM - bootm starts my kernel ... BUT no serial activity ... I am using the vision ICE currently to debug the kernel start up but it has a problem stepping through the 'rfi' etc when memory protection is running. So currently I can only really peek at the PC and see that I am indeed excuting kernel code. I believe my memory map is ok: MEM VIRT PHYS RAM 0xc0000000 0x00000000 IMMR 0xff000000 0xff000000 My pc seems to get beyond start_kernel ... but I don't see the kernel banner printed or anything ... with an ocillioscope I don't see any serial activity at all after I exit ppcboot ... I have check the following so far to the best of my abilities (until I get a BDI 2000) ... and the MMU looks ok ... and my SMC port B settings are ok as well. Does anyone have any tips that could help me out? For some reason I think either my MMU is not set to what I think it is ... or my SMC config has tanked ...
