Hi Joe, it looks like the mxa_manager service might not be running, or there could have been an issue loading the driver.

Can you please try the following and let us know the results:

  1. Check that the driver is loaded with sudo lsmod | grep memx → should print that the module is loaded
  2. Make sure the device initialized too with ls /dev/memx* → checks if the /dev node exists
  3. If the first two pass, try restarting the manager with sudo service mxa-manager restart
  4. If that still doesn’t work, do sudo service mxa-manager status and let us know the output to help with further debug.

Thanks!

I can’t respond with results or email back as I keep getting rejected

Sorry, new users can only put 2 links in a post.

Hmmm, sorry about that! I’ve just updated the site settings to be more permissive. Can you please try again?
