Re: TLB Miss booting linux kernel on ppc 405

Hi Robert,

I didn't solve the problem yet. I'm having problems with the memset_io
in early_init and am studying if the SDRAM is initializing right.
Any progress I'll send to the list.

Good luck,

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.
