Error is "The system request was to an address outside the memory

space"

How & what do I need to Solve this problem?

Hi Chu,

The uCOS ii is not officially supported by OMAP35x and it is possible to appears various problems when trying to use it on omap35x. The list of officially supported OS can be found on the omap3530 product page:

I suggest you to contact with Micrium Embedded Software company about help with porting their product on omap35x.
