Hi,
I have an issue on in-circuit emulation using MAJIC through AXD on SMDK2410.
This image was loaded to SMDK2410 using MAJIC through AXD.
The code is a simple assembly, which is as follows:
AREA subrout, CODE, READONLY ; name this block of code ENTRY ; mark first instruction ; to execute start MOV r0, #10 ; Set up parameters MOV r1, #3 BL doadd ; Call subroutine stop MOV r0, #0x18 ; angel_SWIreason_ReportException LDR r1, =0x20026 ; ADP_Stopped_ApplicationExit SWI 0x123456 ; ARM semihosting SWI doadd ADD r0, r0, r1 ; Subroutine code MOV pc, lr ; Return from subroutine. END ; Mark end of file
However, in AXD, the following is shown as the dissassembly of the above code:
........ ............ ...... ............... ........ ............ ...... ............... ........ ............ ...... ...............
23ffffe0 [0x65656565] strvsb r6,[r5,#-0x565]!
23ffffe4 [0x65656565] strvsb r6,[r5,#-0x565]!
23ffffe8 [0x65656565] strvsb r6,[r5,#-0x565]!
23ffffec [0x65656565] strvsb r6,[r5,#-0x565]!
23fffff0 [0x65656565] strvsb r6,[r5,#-0x565]!
23fffff4 [0x65656565] strvsb r6,[r5,#-0x565]!
23fffff8 [0x65656565] strvsb r6,[r5,#-0x565]!
23fffffc [0x65656565] strvsb r6,[r5,#-0x565]! start [0x65656565] strvsb r6,[r5,#-0x565]!
24000004 [0x65656565] strvsb r6,[r5,#-0x565]!
24000008 [0x65656565] strvsb r6,[r5,#-0x565]! stop [0x65656565] strvsb r6,[r5,#-0x565]!
24000010 [0x65656565] strvsb r6,[r5,#-0x565]!
24000014 [0x65656565] strvsb r6,[r5,#-0x565]! doadd [0x65656565] strvsb r6,[r5,#-0x565]!
2400001c [0x65656565] strvsb r6,[r5,#-0x565]!
24000020 [0x65656565] dcd 0x65656565 eeee
24000024 [0x65656565] dcd 0x65656565 eeee
24000028 [0x65656565] dcd 0x65656565 eeee
2400002c [0x65656565] dcd 0x65656565 eeee
24000030 [0x65656565] dcd 0x65656565 eeee
24000034 [0x65656565] dcd 0x65656565 eeee ........ ............ ...... ................ ........ ............ ...... ................ ........ ............ ...... ................
Hence while single-stepping the instructions upto ADD r0, r1 it is actually executing strvsb r6,[r5,#-0x565]!. I guess it it is a configuration issue, but I am clueless as where I made the mistake. Can you help me on this?
Thank you, Sharafuddeen N
