Hi,
Disassemble a bit more. Look at the code after the warm_reset label.
I dissabled the whole image using the following command:
$ arm-elf-objdump redboot.elf -D > redboot.asm
clippings near warm_reset:
00001204 <warm_reset>:
1204: e3a00000 mov r0, #0 ; 0x0
1208: e59f14c8 ldr r1, [pc, #1224] ; 16d8 <_eCos_id+0x3c>
120c: e5912008 ldr r2, [r1, #8]
1210: e5802008 str r2, [r0, #8]
00001214 <start>:
1214: e3a00000 mov r0, #0 ; 0x0
warm_reset is laid at 0x1204.
clipping from the redboot.srec file:
S02B00002F726F6F742F65636F732F746573745F696E7374616C6C2F62696E2F726564626F6F742E7372656362
S2140010000E0000EA18F09FE518F09FE518F09FE53F
S21400101018F09FE50000000018F09FE518F09FE527
does not have anything for addresses from 0x0000.0000. For some reason the
image has the hardware vector's starting 0x1000.
Please help me out!
Thanks a lot,
-Mike.
