How to erase and reprogramming SPI EEPROM without hardware changing involved?
Hi, we have FX3 board which already has a programmed SPI EEPROM, and every time when the device plug on to host, the device take a SPI boot and the firmware on SPI compeletely takes control of the device , which gives us a firmware vid pid, descriptors etc.
Now I have a question here, how can we reprogramm SPI EEPROM on this device without hardware changing involved ( such as cut wire/reconfig pin connection), it apparently does not support Cypress FX3 vendor specific command for the new firmware download ( or erase). Any idea?
