Hi,

I tried to connect QuickFeather to my MAC running Ubuntu 20.04 LTS via VirtualBox.
According to the System info, the USB device is connected to Bus 1.
So I tried to run this command:
sudo putty /dev/ttyUSB1 -serial -sercfg 115200,8,n,1,N

But I get the following fatal error message:
Unable to open connection to /dev/ttyUSB1:
unable to open serial port

Has anyone had this issue?
Thanks

We have seen report that Ubuntu 20.04 does not recognized the QuickFeather TinyFPGA IP. May need additional USB driver for Ubuntu. We'll check and report back.

Any update on this?

QuickFeather is compatible with Ubuntu 20.04.4. The procedure to get the QuickFeather to work with Ubuntu 20.04.4:
1. download the latest release of TinyFPGA-Programmer from: https://github.com/QuickLogic-Corp/Tiny ... pplication
2. From the location of download (file 71-QuickFeather.rules), execute the following commands:
>sudo cp 71-QuickFeather.rules /etc/udev/rules.d
>sudo udevadm control --reload-rules
>sudo systemctl restart ModemManager.service
3. Install apio package: sudo apt install apio
4. Reboot the system
5. Execute in CMD: apio drivers --serial-enable
6. Connect QuickFeather board via USB
7. Execute: ls /dev/ttyA*; typically, QuickFeather will show up as /dev/ttyACM0
Follow the UserGuide for executing the diagnostic.

I also found that VirtualBox needs to have the Virtuabox Extension Pack installed to recognize USB 2.0 and 3.0 devices.

After that, I was able to find the QuickFeather and run the preloaded program for LEDs, and the device was assigned to ttyACM0, not ttyUSB0

Good to know with regard to Virtual Box.

I still have problem to make it work on VM workstation 15 player for Ubuntu20.04.

For apio install, I have to use
pip3 install -U apio
instead of
sudo apt install apio

After the apio driver is enabled, still cannot see device in /dev/ttyACM0.

BTW, the VM can detect Merced board.

Please confirm that the system is reboot and cmd "apio drivers --serial-enable" is entered before connecting the QuickFeather board to the USB port.

Yes. System is reboot and before plug in the board, use apio drivers --serial-enable to enable.
The log shows

phil@ubuntu:~$ sudo apio drivers --serial-enable
[sudo] password for phil:
Configure Serial drivers for FPGA
Already enabled

And check the ttyACM again still no good.

ls /dev/ttyA*
ls: cannot access '/dev/ttyA*': No such file or directory

jumping in late in the conversation. I have had Vmware work on a Mac with ubuntu 18.04. I might have run the Apio commands on the MacOS also as I was having issues getting the Mac to properly recognize the USB device.
Could you try the lsusb command on both the Mac and the VM?
