Guru mediation error #653

Arduino version 1.8.13 arduino-lmic v3.3 TTGO T-Beam V1.0 Board ttgo LoRa32 OLED-v1 Upload speed: 921600 Flash freq: 40Mhz Core debug level: None

I tried to use the lmic v3.3 library, with the ttn-otaa example. The code successfully uploads to the board but I got the endless loop:

On 9600 baudrate:

Did you take a look at line 53 of hal.cpp? What's it doing? (Yes, I could look, but it's better to document the process.)
