Hi Guys,

I am trying to use ported uCOS-III on the LPC1769 MCU with LPCExpresso board.When I created a debug image of it, I found that the debug version of axf file size is 2,353KB (I could try with release image too), while from the specification of LPC1769, I found that it has only a flash memory of 512KB on-chip, So Can anybody guide me that what shall be done to achieve uCOS-III flashed in it.
I would like to actually add an External ROM in addition so that I can use internal and external both for flashing. Please also advice me if possible with small information of External ROMs too which I could use with this MCU.

Regards,
Mayur

The size of the AXF file is nothing to do with the size of the image in Flash. Suggest you read this helpful little FAQ from CodeRed

Thanks a lot @TheFallGuy. It was quite useful.

µC/OS-III’s footprint can be scaled to contain only the features required for a specific application ([COLOR=Red]typically 6–24 KBytes[/COLOR] of code space residing in memory).
