Updating the firmware on the CerboGX

Updating the software on the CerboGX:

desktop $ scp venus-swu-einstein-20211207113338-v2.80_31.swu root@cerbogx:/data/swu/
cerbogx # ln -s /data/swu /media/dataswu
cerbogx # /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
