Hallo All

Has anyone had such an experience?

I was uploading using the Philips FLASH utility and moved the program
window. The upload failed and I had to start again.

The next time I kept still and it worked.

But the board didn't start up - it went back to ISP mode since it
communicated with the FLASH again. So I repeated the download and
again the board didn't start. Again I downloaded the code and checked
the contents of the FLASH using "FLASH  buffer operations". Interrupt
vectors were in place and I recognised a lot of strings so seemingly OK.

Still the board didn't run.

Then I noticed that the contents of the FLASH were always 0xff after
rebooting the card, although the contents of FLASH was a program
before rebooting. This means that the chip is deleting FLASH on every
reboot...?

(The program runs on another board and so it's not the program doing
it itself). Another strange thing is that the blank check is still
failing although I don't see any data other than 0xff in the whole chip.

Can a device fail like this and could it be cured by loading another
ISP boot code?

I have never experienced such a thing before and have done hundreds of
Uploads in the past on several boards.

In any case I'm keeping my mouse very still when loading because I
can't afford to loose another board!!

Any one know more????

Cheers
