Hi,
I was trying the configuration which you suggested. It loads the exe file, but same problem again...it stops after printing continue and never comes out of it.
the output is here for your reference,
-----------------------------------------------
gdb) target remote COM2
Remote debugging using COM2
0x0 in ?? ()
(gdb) set remotebaud 38400
(gdb) load hello.exe
Loading section .rom_vectors, size 0x40 lma 0x20000
Loading section .text, size 0xafb0 lma 0x20040
Loading section .rodata, size 0x3f5 lma 0x2aff0
Loading section .data, size 0x4e8 lma 0x2b3e8
Start address 0x20040 , load size 47309
Transfer rate: 27033 bits/sec, 301 bytes/write.
(gdb) continue
Continuing.
----------------------------------------------
please suggest...
regards,
- Nagendra.
