Well, JTAG should normally be straight forward. I'm using it as the only
debugging method for my ARM9 target (besides LEDs/diag_printf()s)
instead of RedBoots GDB.
1.) Fire up your JTAG<->GDB proxy or server or whatever it's called (in
my case openOCD)
2.) call <toolchain-prefix>-gdb / -gdbtui
3.) in GDB:
target remote :<whichever port the server is listening to>
file yourimage.elf
load
4.) start debugging with gdb / gdbtui
Works absolutely perfect on my ARM9 target with openOCD and a self-built
USB-to-JTAG Adapter (based on FTDI2232).
Cheers,
Manuel
