Hello everybody,
I am tryng to upload and debug my code on a LPC2146 chip in an asctec board.
I have Olymex ARM-USB-TINY-H jtag interface (for OpenOCD and GDB).
I have installed OpenOCD 0.4.0, Eclipse CDT and yagarto and I am trying to debug using zylin native.
I followed the tutorial in yagarto which is very useful, and the tutorial in olymex but the first is for sigger jtag interface and the second one does not explain everything.
When I run openOCD I got the same message showed in the olymex tutorial (this should mean that I got the communication with the jtag intarface)
but I can not debug.
I run OpenOCD with the following config files (both provided by olymex):
-f /../olimex-arm-usb-tiny-h.cfg
-f ../target/lpc2148.cfg
(my target is LPC2146 but I guess the config does not change since the only difference is the flash memory)
so far should be ok (at least according olymex tutorial)
When I debug I get these msgs:
target remote localhost:3333
0x00000000 in ?? ()
monitor sleep 500
monitor poll
background polling: on
TAP: lpc2148.cpu (enabled)

monitor sleep 500
monitor soft_reset_halt
requesting target halt and executing a soft reset

thbreak main
Hardware assisted breakpoint 1 at 0x40000320: file src/main.c, line 73.
continue
it does not look complety wrong but probably I miss some Commands.
My Init Commands are:
target remote localhost:3333
monitor sleep 500
monitor poll
monitor flash probe 0
monitor flash erase 0 0 13
monitor flash write 0 main.bin 0x0
monitor reset run
monitor sleep 500
monitor soft_reset_halt
monitor arm7_9 force_hw_bkpts enable
symbol-file main.elf
thbreak main
continue
I am not using any run command.
Which exact GDB initialization commands should I
use in my debug configuration?Should I use Run commands?
Any advice would be very appreciated!!
Thanks in advance.
