LPC2478 Port

Posted by Nico Bollen on July 13, 2009
Did anyone already made a port for the NXP LPC2478.
I was trying to do so using Rowley CrossWorks v2.0, project builds but when debugging it seems that the processor always ends up at:

b pabort_handler

in the file Philips_LPC230x_startup

I don't think it will be too different to to the LPC2368 demo. Did you put the CPU in Supervisor mode before calling main()?

I've tried to debug and noticed that the processor calls the abort handler when the following instruction "SUBSPC, LR, #4" is called in the function "portRESTORE_CONTEXT".
Does anybody have an idea??

Make sure the processor is in Supervisor mode before that line is executed. Best to use the start up files from from the FreeRTOS download that set Supervisor mode before calling main.

Supervisor mode? how does that work?

You where right, added the following to the preprocessor defenitions:
