[En-Nut-Discussion] debugging application on ethernut board 3.1 with Eclipse

[Paul Govers]

Hello All,

 

I am trying to debug my application on a ethernut board 3.1 with eclips
but when I try to debug I get the following message in my eclipse IDE:

 

source C:\ethernut-4.9.8\nutapp\combiketel\prj\eclipse_ram.gdb

It seems that the command 'arm7_9 sw_bkpts enable' requires more
arguments and there is a problem on line 18 in my .gdb file(that line:
load)

 

My eclipse_ram.gdb file looks as follows

 

target remote localhost:3333
monitor reset
monitor sleep 500
monitor poll
monitor soft_reset_halt
monitor arm7_9 sw_bkpts enable

 

# Ethernut 3 remapping is required to access external flash memory.
monitor mww 0xffe00000 0x1000212d
monitor mww 0xffe00004 0x20003025
monitor mww 0xffe00008 0x21002026
monitor mww 0xffe00010 0x22002e3e
monitor mww 0xffe00020 0x00000001

 

# needed for gdb 6.8 and higher
set mem inaccessible-by-default off

 

load
break main
continue

 

I have followed the steps on the following websites
http://www.ethernut.de/en/hardware/enut3/openocd.html
http://www.yagarto.de/howto/debugnutos/index.html

 

before I start debugging I start openocd with the following parameters
C:\ethernut-4.9.8\nut\tools\win32\openocd.exe -f
interface\turtelizer2.cfg -f ethernut3.cfg

 

Anyone any idea what i doing wrong?

 

Greetings
Paul
