Vector Table Offset LPC1788 (VTOR) - NOR Flash

@Marc Crandall

Hello,

I'm using uVision 4.20 and an LPC1788 development board.

The development board has external NOR flash at CS0 (0x80000000). I am able to download code to the external NOR flash using and INI setup file but I can't seem to write the VTOR register with 0x80000000.

The exact code and setup modified to run from iRAM works without issue (@ 0x10000000).

Does anyone have any ideas why I cant write VTOR with 0x80000000?

(Note the code runs until there is any interrupt and than crashes)

Thanks.

Mac
