SEROUT2 fails on newer 18F2610

[gabrielg74]

Hello,

I've been programming 18F2610s for several years now without a problem.
Now, I got a new batch of 18F2610s date coded 0804, and using the exact same code from several years it does not work. SEROUT2 sends out garbage.

I have a couple of older PICs date coded 0427 and 0730 and they work just fine, but 12 newer ones just won't work.

Is anybody aware of a silicon update that could affect SEROUT2 on this PIC?

Is there a workaround for this?

Any help will be greatly appreciated.

Thanks, Gabriel

Internal or external oscillator?

[gabrielg74]

External, 20MHz crystal.
Tried 5 different boards with the new PIC (fails) and with the old one (works ok).

Just looked at the ERRATA sheets from Microchip.
Nothing specific to that particular issue, but a lot of things that could be tied into it.
Suggest paging thru them to see if you can find anything.

Which version of PBP are you using?

[gabrielg74]

PBP 2.4.6.0

Already checked the Errata and could not find anything that could be causing this.

Well,,,,,,,,,,show the code. Maybe there's a bit changed in there somewhere.
