Coldfire 52235evb debug problem

[Roberto Abbiati]

Hi,
I'm using eclipse and Sourcery G++ Lite Edition with a coldfire EVM. I
have used the FREERTOS code (Coldfire V2 RTOS and TCP/IP Demo).
I can build the project and download the program in flash memory using
freescale's "CF Flasher 3.1".
Problems arise when I try to debug the code.
To identify the problem, I have used the command prompt console and text
commands. The steps are:
1/ m68k-elf-gdb RTOSDemo.elf
RESPONSE:

2/ (gdb) target remote | m68k-elf-sprite pe://USBMultilink m52235evb
RESPONSE:
Remote debugging using | m68k-elf-sprite pe://USBMultilink m52235evb
m68k-elf-sprite: Opening P&E USBMultilink port 1 (USB1 : USB-ML-CF REF :
Future
MCF5223xPoE Badge (PE6011471))
m68k-elf-sprite: Target reset
0x00000000 in __cs3_interrupt_vector_coldfire ()
 
3/ (gdb) c
Continuing.
RESPONSE:
Program received signal SIGTRAP, Trace/breakpoint trap.
0x0000000a in __cs3_interrupt_vector_coldfire ()
 
If I try to continue, I always obtain this kind of response.
 
Instead, if I try the step command:
 
(gdb) step
RESPONSE:
Single stepping until exit from function
__cs3_interrupt_vector_coldfire,
which has no line number information.

and the program waits forever, so I must close the command prompt shell.
 
Could anyone help me?
Thanks
 
Roberto
