Using MacOS screen as serial terminal for my nucleo144-H743ZI2
Trying to do this.
Whilst it can connect using the serial port, nothing come out. I suspect is that whenever I try to recycle the power (seems no other way to activate the firmware), the /dev/cu* is lost. Hence, whilst this command is ok after the recycle it is too late for the microcontroller ... The program function all good like I2C etc. as my I2C monitor can be displayed. Just no serial.
screen /dev/cu.usbmodem11303 115200 -L
warning message as below indicating some issue.
Target is not responding, retrying...
Shutting down...

Exit.

But I have to recycle the device, what can I do ...
