Hi,
my goal is to update the firmware of a MPPT (75/15 smartsolar) connected to a raspberry pi4.
I managed to do it using a serial port redirection to a windows computer with mpptdump.exe but I will really like to do it directly from the raspberrypi.
I found this documentation about the venus OS that allow to do it with the dup tool. But I am unable to make it work on my raspberry.
https://github.com/victronenergy/venus/wiki/commandline---operational
dup -s /dev/ttyO2 -f filename.dup
I copied the /usr/bin/dub from the latest venus image for rpi4 but it's not enough to make it work, I guess I am missing librairies and dependencies?
Any clues?
Best Regards,
Martin
