Hi Dave,
   It still shows data tlb error tho.
   I found it occur error around the GET_GOT of start.s.
   The SRR0 and SRR1 show the error address of system.map is _start_cont.
   Suspect the DDR setting problem ?? But I thought all the DDR setting are
from SPD.
   So, I didn't set any entry of DDR in TLB1.
   Any hint?
