[ECOS] Pb to start application with GDB

[alix t <talix1603 at yahoo dot fr>]

Hi,


I'm developping an application RedBoot-Ecos for a new
motorola evaluation board with powerpc MPC8275.

I have developped a RedBoot in ROMRAM startup mode.

I have problems to start an application with GDB. When
I use continue command, application never start ....
The only way to start the application is to use the
following commands, nexti + jump *start_address. Any
suggestion?

 

Behavior with Cont command:

(gdb) set remotebaud 38400

(gdb) target remote com1

Remote debugging using com1

0x0000ece4 in ?? ()

(gdb) load

Loading section .text, size 0x7860 lma 0x51000

Loading section .rodata, size 0x9ec lma 0x58860

Loading section .data, size 0x538 lma 0x59250

Start address 0x51000, load size 34692

Transfer rate: 27753 bits/sec, 502 bytes/write.

 (gdb) cont

Continuing.

 

Behavior with nexti + jump command: 

 (gdb) set remotebaud 38400

(gdb) target remote com1

Hello, eCos world!
