Debug LPC22xx FreeRTOS with ULINK

Posted by Nobody/Anonymous on March 22, 2005
Hello,

I have problems to get the FreeRTOS
to run on a LPC2229 with external RAM
for debug purpose with the ULINK debugger.
Code download is OK, but debug cause problem.

Can you provide more information?

Which compiler are you using?
What is the problem exactly?
What have you changed to get external RAM working?

???

oh sorry, yes..

The uVision3 IDE + ULINK
and using the Keil ARM tools (DKARM V1.5)
I've modified the settings for debuging from external RAM
e.g CODE org ..and size, also for RAM.
I'm use a initialization file (XRAM.ini) with some settings for the debug session.
Also a modified startup.s.
this normaly works with other projects.
If I start the debug session with FreeRTOS port, the code is downloaded normaly to RAM via the ULINK.
program runs until main and wait.
stepping through the code (TaskCreate) makes nonsense and caused a total crash.

any idea ??
maybe a right startup.s ??

Thank's

Problem solve,

PABCAKE = problem exist between chair and keyboard !

the size of code and data space should never exeed
the physical size of the used RAM for debug !

thank's
