Is this load address for kernel is correct? likely to have 8000 multiples.. check it once. > > ## Starting application at 0x02000000 ... > software interrupt > pc : [<0200001c>] lr : [<00633cac>] > sp : 005fef68 ip : ffffffff fp : 005ff7de > r10: 005ff3de r9 : ffffe804 r8 : 005fffcc > r7 : 005ff388 r6 : 00000001 r5 : 005ff38c r4 : 02000000 > r3 : 30383101 r2 : f1012000 r1 : 005ff38c r0 : c0c0e0c4 > Flags: nZCv IRQs off FIQs off Mode SVC_32 > Resetting CPU ... Try to debug the value from pc.
