Updating the firmware on the CerboGX

Updating the software on the CerboGX:

scp the .swu file to the device onto /data/swu/

ln -s /data/swu /media/dataswu

/opt/victronenergy/swupdate-scripts/check-updates.sh -offline

note: swu_base = swu_name-machine where swu_name = einstein, and machine = venus-swu so swu_base = einstein-venus-swu the check script does: ls -r $dev/${swu_base}-*.swu $dev/${swu_base}.swu 2>/dev/null | head -n1 So, in short, make sure the .swu filename is like: venus-swu-einstein-20211207113338-v2.80_31.swu
