Could the post by 'Mike-ski' be related?

I just received a call from a customer who reports that the software that we programmed in 'disappeared'. They reprogrammed the part and it is now working OK.

We use FlashLink (FL-101B) to program the parts. All parts are tested 2x after programming. This is for a upsd3253.

Any suggestions? Is there any methods for the a flashed programmed part to lose its programming? There is no bootloader in this part.

Thank you.

We are currently developing 10+ products with the uPSD33XX family of parts

We have noticed on several occasions (3-4) that program flash memory seems to get corrupted during power cycling. This problem has occured only a few times during our testing of several products under development .

My question is has anyone else experienced this and what might the cause be. We are experienced developers but are new to the uPSD parts.

Thanks for any help or suggestions
