Hi all, My board can't boot normally, and I found it just hang in data tlb error through the system.map. Could any one help for this? Some regisers are as below: ============================================ DEAR: 0xf400fff0 (L1 init ram base address is 0xf4010000) IVPR : 0xfff80000 , IVPR3: 0x000004000 EELADR: 0xf4010000 , CSn_BNDS: all 0x00000000 (I think SPD of DDR is not found yet) L2MMU_TLB0 : 84000000 51000000 ff7000000 ff7000000 (CCSR is not relocated to 0xe0000000 yet) ============================================

What I think the problem might be 1. I didn't access the SPD to initial DDR , so failed ? 2. The TLB1_5 should take away ? 3. I shall add one more TLB for DDR ? 4. The real problem is not related with any above, and I shall post the other regisers for check ??
Thanks.
