Is there an easy software way to remove the vid/pid from the EEPROM and ge back to the initial Cypress one?
Thanks

CY7C68013 remove EEPROM

If you're feeling lucky, just ground the E2PROM data pin while you plug in the device. With the right driver installed (bound to a Cypress EZUSB) you can download some software to wipe the first byte of the E2PROM.

Although it seems like that should work, in my experience it identifies differently on the bus than an unprogrammed FX2. Opening the data line at the EEPROM does work as you would expect, but of course you have to restore the connection with the power on.

The above method is what I use. Or unpower the device (EEProm) and boot. Once you are up as a generic Cypres DEvice then enable the EEProm and use their EEProm write routines to put ANYTHING other than 0xCx in the first byte. Or wipe the entire EEProm to zeros.
