I have a customer using BQ78PL114 but he would like another GPIO-USB interface. I have sent him one but he can't upgrade the firmware. His description of the problem is below
The first one we had with the Eval kit works, I have it rigged up here connected to a working prototype board, everything is correct.
I've just unpacked the new interface, and plugged it in. It was recognised by XP, as the was the usual bing bong from the speakers to say it is connected.
Ran Bqwizard, no connect, will not talk the working prototype board.
Installed Bqwizard on another pc, this has never seen any Ti software, Connected everything up, same problem no work.
Tried to verify the firmware as before, and the software come up with, failed to find byte 0000 in flash.
Seem's there is a problem with these interfaces, I've seen on a web trawl that other user's have been having the same trouble!
