Re: JTAG problems with Olimex LPC2106

2004-10-02 by dave_albert

Hmm...I have not tried the Rowley IDE and would prefer not to have to
change my toolchain at this point; we have lots of code built around
the GNU tools under cygwin and linux and they work very well (except
for this :-)  They are also free and open-source which I am very fond
of.  

I've tried all of the software configurable settings for the OCD
software with no luck.

Back when it *was* working, I was able to debug LPC flash although it
was less fun than RAM debugging...you can set 1-2 hardware breakpoints
and they do work with OCD/GDB...I can tell you how if you are interested.

Regards,
Dave

BTW, I love your development boards!
