Are you using NX2LP (CY7C68023 / 33) DVK i.e. NX2LP daughter board mounted on top of FX2LP board? Or is it your custo board with NX2LP chip alone? Also, how are you saying that 0x6813 is the correct PID? we are not using 0x6813 PID for anything? Are you programming it with that particular PID? Please clarify.
