I'm trying to run freertos onto my custom RM48 board and have followed the TI recommend instructions for doing so. However, I get my prefetch Abort error when I create an OS task. Specifically, I get the prefetch Abort immediately after executing this line highlighted below.
; Start the first task by restoring its context.
public vPortStartFirstTask
vPortStartFirstTask
cps #0x13
portRESTORE_CONTEXT
When I step into this macro it seems to manipulates registers normally until at some point my registers look like this:
When I exit the portRESTORE_CONTEXT macro my registers look like this:
From here the next instruction is the prefetch abort. How do I go about finding out what causes the abort?
My link file looks like this:
