PIC16F877A - Verification Error [solved]

[tomwp]

Hi,

I am setting up the boot loader for a PIC16F877A. I have compiled and programmed the loader fine. When I try to down load the application it gets 95% of the way through, then fails on verification:

Erasing page 434...ok
Writing row 434...ok
Erasing page 435...ok
Writing row 435...ok
Erasing page 1999...ok
Writing row 1999...verification error, 1 try
Writing row 1999...verification error, 2 try
Writing row 1999...download failed

Why is it suddenly jumping to page 1999?

I have tried this with a few different boardrates all with the same result.

Thanks,

Tom.
