USB Blaster issues with Ubuntu 20.01

[AutoSpiderZ]

Good Afternoon and Thank You for helping resolve this issue.

I have tried everything, scouring the internet for days to use my Altera USB Blaster on Ubuntu 20.  It works with the drivers on my windows machine but I do all of my development on my Ubuntu laptop.  I have set the permissions, but I get an error message from dmesg|tail when I first plug in my device to my PC.  Also, installed Quartus II, and jtagd --debug shows a message can't claim interface.  jtagconfig says that the chain is already in use.  I took screenshots and have them on my developer blog here

Any help is greatly appreciated.  Kind Regards, Mike

Hi,

Just would like to check, have you add the file as shown in the user guide below?

Thank You.

Yes, and the permissions seem to be ok.  The error seems to indicate the device is in use, but I don't think there is any process running that may be causing this ???  I've been working on my windows station, but this is not conducive to a more rapid development environment.  I am looking forward to trying boundary scans as well, but, would like to do all of this from my more modern laptop with Ubuntu 20

Hi,

Can you try the following?

• kill the jtagd process and run it as root.

Thank You

I have tried this to, but the errors are the same.

I think the error message in dmesg|tail when I first attach the device is telling me it is not setup properly.

Hi,

I did some searching. For this error, can you try to reinstall the driver and then remove all the unecesary USB to prevent it from being using?

On Linux there is no driver?
