Re: TLB Miss booting linux kernel on ppc 405

Have you solved your problem??

I'm having the *EXACT* same problem on a Virtex4FX60.
The device is configured with PLBv46/MPMC3/LL_TEMAC.

I'm under the suspicion that the PLB is issuing an error when switching
to virtual mode and that there is either a timing/synthesis error or a
fundamental error with the way the FPGA is getting synthesized with the
PLB. 


RJW.

Executing without single step the exception doesn't occurs. But at
__log_buf I get only trash, even after reseting the processor.
How can I send some characters to uartlite on asm code?

Great.  This confirms that I am not crazy.  You are having similar
results as I did.  But I still don't yet know why single-step and
memory read can't be used in virtual mode...
