Hi,when i upgrade uboot from 1.1.2 to v2010.12-rc3 i met a great number of problems. Before, i use skyeye to simulate uboot. furthermore i use "arm-linux-gdb u-boot"(eldk-4.2) to step by step executes u-boot the result like below:

(gdb) tar remote :12345 Remote debugging using :12345 _start () at start.S:40 40 start.S: No such file or directory. in start.S Current language: auto; currently asm (gdb) (gdb) step _start () at start.S:41 41 in start.S (gdb) _start () at start.S:42 42 in start.S (gdb) _start () at start.S:43 43 in start.S (gdb) _start () at start.S:44 44 in start.S (gdb) _start () at start.S:45 45 in start.S (gdb) _start () at start.S:46 46 in start.S (gdb) _start () at start.S:47 47 in start.S (gdb) reset () at start.S:108 108 in start.S (gdb) reset () at start.S:109 109 in start.S (gdb) reset () at start.S:110 110 in start.S (gdb) reset () at start.S:111 111 in start.S (gdb) reset () at start.S:118 118 in start.S (gdb) reset () at start.S:124 124 in start.S (gdb) call_board_init_f () at start.S:129 129 in start.S (gdb) call_board_init_f () at start.S:130 130 in start.S (gdb) call_board_init_f () at start.S:131 131 in start.S (gdb) call_board_init_f () at start.S:132 132 in start.S (gdb)

These indicate that in start.S,first instruction:b reset not jump success The process just go from one instruction to the next. What may be the problem?any suggestions is appreciate. MrGates
