Program Flash above 0x20000 on 56F8366

[tim_robbins]

I am using a 56F8366. My code size has recently jumped above 0x20000, which is about half way thru the total program space. Its also a transistion point from the first 256k space to the other 256k space.

Everytime my software tries to execute an instruction in the code space about 0x20000 I get a illegal op code interrupt. After further review, it appears that its writing all zeros to anything above 0x20000 instead of my code.

Any one have any ideas? I am using CW 8.1.1a

Thanks,

Tim

Hi,

I'm not sure but it could be similar to another problem we investigated 2month ago for another chip.

Hello!

What was the solution? I am having very similar problems with 56F8345 and CW 8.0. Problems start immediately after program flash size reaches 50%. First I had problems with function pointer array initializations and now I have new weird problem that I haven't been able to kill yet. And I am not using PE.
