PIC18F2550 Problem - GoSub or GoTo fails if the jump is too far

Thanks Alain. That's what Darrel recommended as well. So I did upgrade to 8.92. And that seems to partly fix the problem. If the firmware is burned DIRECTLY to the PIC it runs okay. But... if the Trace Bootloader is installed it still has problems with GOSUB.

Dr. Bob at Trace has also been looking into this and sent me a new version of the 18F2550 bootloader to test. Hopefully that will correct the problems. I didn't get a chance to test it last night.

SUCCESS!!!! Everything appears to be fixed with the updated version of Trace Systems Bootloader.

So there were 2 problems: Outdated version of MPLAB, and outdated version of the Trace Bootloader. Thanks to Darrel at ME Labs and thanks to Dr. Bob at Trace Systems for getting me back on track!

Thanks MilesTag-
I was having a similar problem with an 18F46K80 with it resetting on me - didn't know what to do. Kept cutting subroutines until nothing left but labels and returns.
I just updated my MPLAB and it seems to give me back my program!

This place is Awesome for knowledge.
