iMX 25 evaluation board (Freescale)

Hi all.

I'm trying to configure Eclipse to allow integrated debugging against the evaluation board MCIMX25LPDK from Freescale running Linux (iMX255 processor).

I've succeded in building a Hellow world app and JLink attempt writes it to the target. My hitpoints are never hit though - any ideas?

best

My GDB scrit is as follows (Do I need to do any additional configuration?):

target remote localhost:2331

monitor endian little
monitor reset

monitor speed auto

set remote memory-write-packet-size 1024
set remote memory-write-packet-size fixed
monitor flash download = 1
monitor flash breakpoints = 1

load

break main

Hi Thomas,

are you trying to debug in RAM or in Flash?

If you are trying to debug in Flash:
As far as I can see, the iMX25 does not provide internal flash memory.
Currently, the J-Link flash programming capatibillity comes with support for internal flash memory only.
Flash programming + flash breakpoint support for external flash memory is on our schedule (will be implemented this year, but no more specific schedule yet).
If you want to debug in external flash memory, you have to download your application with another application first (e.g. J.-Flash).


Best regards
Alex

Hi Alex.

Thanks for your response. I'm trying to debug in external flash so I'll look forward to your update. :)
