Hi all,
I'm trying to track down problems loading a linux kernel on my custom 8548 board off of 1.3RC3 - it loads sometimes via a ramdisk and gives me a bash shell - but most times it crashes in unusual, different places.
I ram mtest in the monitor and it crashes at 00000a90 . When using mw I get:
=> mw 00000a90 cafecafe NIP: CAFECAFC XER: 00000000 LR: 1FFC109C REGS: 1ff9dc40 TRAP: 0700 DAR: 00000000 MSR: 00001000 EE: 0 PR: 0 FP: 0 ME: 1 IR/DR: 00

I can write to 00000a90 via the bdi . u-boot otherwise runs perfectly. Any ideas? Robert
