Using Atmel ARM based controller via JTAG debugger

[gylab]

Hi!
I want to use the Atmel 91Rxxxx controller.
Did someone used any Atmel ARM based controller via JTAG debugger?
I made the Wiggler jtag interface, I have an iSystem jtag interface, an AT91 EB40 evaluation board, but I could not start any jtag or any debugger.
What (free or cheeper) debuggers can drive any public jtag interface?
Can someone help me?

If you are talking free then use the wiggler with ocdremote (www.macraigor.com) and gdb or insight. It has limitations but is free.
One note about the new versions of ocdremote (>2.07) - make sure the parallel port connector has a link between pins 8 and 15. The newer versions check this. If it is not present they fail with internal error 43.

macraigor internal error

Thank you for your answer.
I tried my wiggler with connection 8-15 pins, then it is working!
If I interpret correctly, the 'internal error 43' message means: buy wiggler from me for 150$.
The ocdremote and ocd commander from Macraigor is working. What are the limitations? These limitations are the limitations of system, or limitations of a free version?

Another question: if I build an accelerated jtag (with hardware shift register), can I obtain a driver source what I can modify for my hardware? e.g. the ocdremote or ocdremote like driver is available?

Will the wiggler work with AT91SAM7S?:

The wiggler will work with a sam7.
groups.yahoo.com/group/AT91SAM7 is a good place for info

There are numerous jtag drivers on the net that support the wiggler interface

hri.sourceforge.net/tools/jtag_faq_org.html
as a starting place.

Yeah.. I remember when that guy started up that yahoo group (a week or so ago ) 19 total msgs.. But it looks like it will be great with the avg post/day pretty good.

So basically, I will use:


cable.

but what compiler/software programs will I use? I am comfortable with GNU C.. but I am still a little confused on what software is needed.

thanks for the quick response!

hmm.. well I have seen this programming cable before.. but I didn't know ifit could program the sam7:

https://www.olimex.com/dev/arm-jtag.html

It says it is: "MACRAIGOR WIGGLER COMPATIBLE" so wouldn't that mean it can program all the atmel's at91 line?

thanks again guys!

And is the programming cable/tools the same for all:


AT91M42800A Series
AT91M55800A Series
AT91RM3400 Series
AT91RM9200 Series
AT91SAM7AX Series
AT91SAM7SXX Series
AT91X408XX Series

chips?

thanks-Lee

ocd commander internal error 43

Start with gcc from www.gnuarm.com, this also includes gdb/insight.
Also grab ocdremote from site mentioned above, read faq and away you go.
