Re: [lpc2000] JTAG debuging

2004-07-22 by Ben Lau

Hi Jim,

    It is great to hear your work :)

    I am currently using OCDLibremote + GDB(from GNUARM) with a wiggler
compatible adapter to debug lpc2104 application. The general procedures:

1) run OCDLibRemote

OCDLibRemote -c ARM7 -d Wiggler -a 1
(using the first parallel port)

2) run GDB in another console

arm-elf-gdb image
target remote :8888
load image
set $pc=0x40000000
continue
