software breakpoints are disabled by default, as they take up one of only two
hardware breakpoint units.
You can enable them form within GDB (like gdb's init file) with:
monitor arm7_9 sw_bkpts enable

Hi,
I ported the lpc2106_blink_ram example to fit the Olimex LPC2103 board.
I made a remap (MEMMAP=0x02), changed the linker-script and
the map-file seems to be fine.
I start the Olimex ARM-USB-OCD with the following config => see
appendix and the arm-elf-gdb in eclipse with
target remote localhost:3333
load
The debugger starts and as I press "Run", I get the following error
messages:
Warning: Cannot insert breakpoint 1
Error accessing memory address 0x400002b4: (undocumented errno-1)
Warning: Cannot insert breakpoint 1
Error: accessing memory address 0x400002a8: (undocumented errno-1)
When I removed all breakpoints an tell de debugger console "delete" =>
the pressing "Run", the program works fine.
Is there a trick I'm not familiar with, or a configuration problem?
Did anyone have this problem earlier?
Currently I have no idea why the gdb reacts this way, when I insert
breakpoints.
