Problem solved...forgot to supply the AVDD (ADC voltage). Now I can replace the Wi-fire board using a PIC32MZ PIM module and a FT2232H module

I have a big camera motion control project, using among other tings some Wi-Fire boards. Since they are not possible to buy anymore, I’m trying to move the project to PIC32MZ module (Exact same MCU as on Wi-Fire) with no other hardware and use a FT2232H module (USB to UART) for the only other hardware I need from the Wi-Fire. Its working when I program the Wi-Fire bootloader in MPLABX and it connects to Arduino and uploads my code, but when the PIC32MZ board restarts the Wi-Fire bootloader never finishes and starts executing my code. LED1 output blinking fast as it do on the original Wi-Fire board during startup. I guess it waits for response from some hardware I don’t have, maybe the Wifi module, but I don’t know how to find the source of the problem and what to do to bypass it. It’s a long way to move all the code from Arduino environment to MPLABX so any tips how to solve this would help a lot.
