The MPC8349EMDS code in wolfgang's git is working well now. No hang. Please check your code carefully.
I've tried and I can't figure out what's wrong. Right now, I have this code in mpc83xx/start.S:
/* For some reason, address translation does not work on the 8349E-mITX */ #ifndef CONFIG_MPC8349ITX /* enable address translation */ bl enable_addr_trans sync #endif
Everything else works fine (I'll be providing a patch for the 8349E-mITX in a week or so). But if I turn on either address translation (instruction or data, it doesn't matter), then the system crashes.
enable_addr_trans: /* enable address translation */ mfmsr r5 ori r5, r5, (MSR_IR | MSR_DR) mtmsr r5 isync blr
The crash occurs right after the 'mtmsr' instruction.
The only thing I can think of is that I'm using the wrong values for CFG_IBATxx, but I have no idea what they should be. I copied them from MPC8349EMDS.h.
