Hi Everhamme
I tried your pinmap on a Firebeetle ESP32 board with a Firebeetle Lora hat and unfortunately, it didn’t work. I got the following in the SerialMonitor which is a loop reset.
I wired up the board as per BoRRoZ diag with additional jumpers D3-DIO0 & D5-DIO1
Any chance you can share your code? I was using ttn-adp and ttn-ota examples from the MCCI LoraWAN LMIC library with the same result for each. Thx

I’ve just discovered that the boot loop only happens when the LoRa cover is attached to the Firebeetle E32. I’ve checked extensively for shorts with no issues. Any ideas???
I did some more testing and it boot loops when D5 is connected to DIO1
