Hello, I created my own custom Arduino Nano 33 IoT using the same exact schematics provided, and the board works successfully, except for the Wi-Fi. I soldered a Nina W102 module onto my PCB but I can't communicate with it yet since there's no firmware. I tried using the firmware update tool but it's not working. How can I set up the W102 module for initial use?
When I try to upload the WiFiNINA firmwate update sketch, I get the following error in the serial console: Unable to communicate with ESP32 boot ROM!
(Keep in mind my custom PCB is a replica of the Nano 33 IoT so the Arduino IDE thinks my board is an actual Arduino).
