hello,

I am using the uPSD323X from last one year. But for the first time i could see that the chip already programmed through JTAG ( more that 5 times)is not getting reprogram/erase.

It's not able to communicate through JTAG . but the previous loaded image is working fine

IT SHOWS: MISMATCH OF IDCODE

here is the attached log file generated

PLZ help

Purvi,

I've seen this message if I accidentally have the wrong uPSD product selected in the JTAG programming screen within PSDExpress. For instance, if I was trying to program a uPSD3254A and I had selected the PSD854 as the device in the JTAG operation dialog box, it will show this error. Maybe take a look at this dialog (or your .jcf file if you're using it from the command line) and make sure it matches.

Best Regards,
