Nexys Video - Firmware for onboard USB JTAG in FPGA Posted August 10, 2020 Thank you for the reply. I was referring to port J15 and the PIC firmware. However, I did miss that IC16 (J13) has an EEPROM so thank you for the information confirming that the programming tool is FTProg. Same question for J15. Is there a method to validate or modify the PIC24 firmware connected to J15? Thank you.
