Problem connecting to ZCU102 - USB UART cable (cannot open /dev/ttyUSB0)

vongracia commented 2 years ago

Hi all,

I am not able to access my ZCU102 using minicom. The command I use is: sudo minicom -D /dev/ttyUSB0 minicom: cannot open /dev/ttyUSB0: No such file or directory

In the past I used this tutorial and it worked perfectly: https://www.centennialsoftwaresolutions.com/post/edge-ai-setup-on-zcu102

Suddenly, I had to reset my laptop and now the port /dev/ttyUSB0 is not accessible. Do you know what could be happening? I'm using Ubuntu 22.04.

Thank you Antonio

@vongracia could you please check list of /dev/ttyUSBx ?

vongracia commented 2 years ago

@tianfang-fafafa Yes. I ran 3 commands:

Any help is very welcome, please. This is driving me crazy. Thanks

@vongracia seems your laptop can't recognise serial port(ttyUSBx), could you try to change another laptop or machine? and is your laptop's system a virtual machine ?

vongracia commented 2 years ago

It is not a virtual machine, it's a laptop with fresh Ubuntu 22.04 installed. @tianfang-fafafa

Please check issue 1013 , the problem derived into something else and I opened to the forum.

Maybe you can give me a hand, Thank you very much
