COM port not detected for Zybo z7 20

[Anoop]

I need a urgent help regarding this, Please help me,

I booted my board with 5V wall connector and when i connect micro usb to laptop com port is not detected, i tried with different laptops too still did not work. I have added USB 0 in my design and it seems petalinux booted just fine since i can see PGOOD and DONE LEDs are on and my counter is running.
I even tried different cables install drivers manually, I can see my petalinux booted and as soon as i turn on my RX led blinks for some time and then stops and board LED and Switches works as i configured. But COM port is not detected. I Tried different PC as well. nothing works. Please let me know the solution.

 

 

Please do help.

Hi @Anoop,

To confirm, you're loading the Petalinux design through the SD card (as opposed to through the USB-UART connection)?

Have you gotten to try a different USB cable? Some cables only transfer power and not data properly. I'm guessing you are on a Linux OS since you are using Petalinux, is your board successfully detected through lsusb?

Thanks,
JColvin

Hi @JColvin
Yes i am loading petalinux through SD Card.

Yes I have tried 3 different cables.

Unfortunetly i am using Windows and terterm or Putty. But in device manager it did not show up the COM port. I will try with Linux OS and let you know.

 

Thanks
Anoop

Hi @JColvin
I tried in Ubuntu OS too but still nothing is detected. lsusb does not show the new device.

Hi

The problem was virtual machine running was avoiding the USB to be detected. Thanks
