tycmd: reboot hangs when uploading from RPi 4B

[SJFOM]

I am running BalenaOS and have a working version of the tycmd tool running on my Raspberry Pi 4B 8G model.

However, when I attempt to upload firmware to a Teensy 4.1 MCU, the tycmd tool has trouble rebooting the Teensy. This is true either:

• If I don't use the --wait flag and the tycmd tool attempts to reboot the Teensy itself
• If I do use the --wait flag, press the user button -> tycmd will have trouble rebooting the Teensy after a successful program.

I have the correct udev rules installed (00-teensy.rules) and they appear in my system.

I have tried building with cmake using the -DCMAKE_BUILD_TYPE=Debug flag but it doesn't seem to yield any extra output. Any ideas on what might be the cause here or what else I could try?

Could you try with the option tycmd --rtc none <firmware>?
