This was set-up using an old "FELIX" workstation from Matthias' office (Zijun & Sanha, April 21st, 2021). It is currently set up to run a RD53A module—the one Zijun has worked on previously.
It is accessible via machine name felix2 from rddev111.

If you get this error in YARR even after flashing the firmware:
[18:46:45:565][ info ][ specComTest ]: Init spec
[18:46:45:565][ info ][ SpecCom ]: Opening SPEC with id #0
[18:46:45:565][critical][ SpecCom ]: Error during initilisation: Open failed
[18:46:45:565][critical][ SpecCom ]: Fatal Error! Aborting!
It is probably due to an issue with permissions. Just do:
sudo chmod 666 /dev/spec0
or write a udev rules file for a more permanent solution:
echo 'KERNEL=="spec[0-9]*", MODE="666"' | sudo tee -a /etc/udev/rules.d/99-spec.rules
