OpenOCD + GDB + Flash Programming LPC2368 Problem

Started by andy4onroad April 3, 2007
I'm having problems with flash programming and an LPC2368 using GDB.
Presently my major problem is that when I pass the command for flash
programming through GDB to the OpenOCD server I get an error from GDB
at the end of the flash programming process:

(gdb) monitor flash write 0 test.bin 0
Ignoring packet error, continuing...
Reply contains invalid hex digit 116
(gdb)

This error is not generated for "monitor flash erase 0 0 0"

Does anyone have an idea what's wrong or what a work-around is?

Here are some relevant setup files:

#
# A .gdbinit to get the Olimex ARM-USB-OCD to run the LPC2368
#
# This connects to a GDB Server listening
# for commands on localhost at tcp port 3333 (this seems to be
# where it gets put for OpenOCD
target remote localhost:3333
# Reset the chip to get to a known state.
monitor halt

#
# Setup OpenOCD and get the chip under control
#
#-enable the debug communication channel to write to memory.
