Not working on Arduino Giga R1 WiFi STM32H747 #759

What type of issues is this?

[ ]Bug or problem compiling the library Can compile and upload, but not running at all

What are you working with?

Modem: SIM808 Main processor board: Arduino Giga R1 WiFi STM32H747 TinyGSM version: 0.11.7 Code: modem.init();

Scenario, steps to reproduce

Im using a SIM808 module and tested perfectly working with my ESP32-S3-Devkit-C, as a proof of no issue at hardware level. However, I recently switched to the fancy Arduino Giga r1 wifi board, I can compile and upload, but TinyGSM library stops the core from running after startup. I have tried minimized codes on both the M7 and M4 core. After modem.init();, everything stop responding, totally none response including simple serial.print().

Expected result

I expect is can be a small bug somewhere, if someone like to look into it, I can help the test.

I connected the RX and TX incorrectly. Thanks for the attention. Remove the issue now.
