We have the PROTECTED memory section defined in the linker command file.
We have the latest FRC 8722 Library file
Has any other teams seen the 8.2v bug resurface? Any ideas?
Thanks!

Are you using any interrupts?
If so, what interrupts are you using and for what purposes.
<<< Let me be a little more transparent. All of the teams that I talked to last
year who were seeing this problem, after applying all the patches, were using
timer 3. I am interested in knowing if you are using timer 3. The patches
move things around in memory, and any movement of variables in memory
affected this problem, without really fixing it. We never saw the problem when
we backed away from interrupt use, although our interrupt based code was well
wrung out on prior year's controllers and never showed a problem. Knowing that
the chip was the same, and that the patches did not fix it for us last year, we
avoided any additional interrupt use in our code this year. One workaround worth
trying if you are not using the Kevin's camera code is to use his lastest code
that changes how the high number pwms are being handled. >>>
