OK. Will download 7.42 and see if that makes a difference

Do you get the same result as before, even with the resistor/cap? Still can't even erase/blank check it?
Everything is identical to the initial attempt at programming. Havent tried to Erase/Blank check. Just tried programming. Will also try that

Is it on a 2431 or are you trying with the 4431?
Both, and multiple devices

When I flashed the 2431 with the MicroCodeLoader .hex file I had to change the config for the brown out voltage. Apparently the BOD was set to on but the trip voltage wasn't specified so it complained about that. Other than that it programed and verified without further problems.
Yes, I got those messages as well. I initially DISABLED BOD with no success, then I tried leaving it enabled but setting the voltage to 4.2V still no success.

I've searched the docs further but beyond the resistor and/or cap "solution" I haven't found anything. It'll be interesting to here what Microchip says.
I spent a long time googling and searching the mchip forum to no avail.

The only reason I have those chips is because I want them for the QEI interface and now my project has hit another delay just because I cant get the bootloader files into the bloody chips

You have now caused me untold grief as I was blissfully unaware of the problem until you suffered from it !! I'm not really blaming you though as I would have hit this problem anyway, its just annoying that both you and Steve have got it to work and I cant
