JTAG debuging

JTAG debuging

2004-07-20 by lynchzilla

Thanks, Gus, for the nice complement.

I plan to develop tutorials on ARM debugging with Eclipse, but it's 
going to take several weeks. For example, the ECOS site has explicit 
instructions on how to download and build the ECOS kernel, but they 
fail on a Windows XP machine with some kind of "firewall" error 
message.

I'm planning to order a Wiggler ($150 US) or a clone thereof in the 
next couple of days.

Seems that there should be two debugging techniques available. First 
is the Redboot monitor from ECOS that would allow absolutely free 
debugging over the serial interface. Redboot has the GDB stubs needed 
by Eclipse.

The second method is the JTAG interface which requires hardware and 
some soldering to the TiniARM board. The Macraigor OCD Commander is 
listed on their site as freeware and I think it supports the GDB 
stubs via JTAG also.

If there's anyone out there that has solved this, please let me know. 
I'd be happy to use your information and produce a clear and 
interesting tutorial on it.

Cheers,
Jim Lynch

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
