Good afternoon Cypress. I worked with the cy7c67300 eeprom on the xilinx ml605 board, I figured it out for a long time and finally was able to flash it with qtui2c, but it stopped displaying in the computer. You can send me the factory EEPROM, and / or the source code for it.

Hi,

Please try 1) cutting off access to EEPROM for EZ-Host when it boots or 2) When the EZ-Host board is powered off you can try to corrupt the EEPROM contents with data 0xFF - so that it loses the scan signature 0xC3B6. After doing this, when the board is powered, EEPROM code will not be used got booting.
