Do you know if Victron program SN on the power boards to sink with the main board?
Or does the Main only get the SN programming?
Donāt know but I doubt it. If I did know, Iām not sure thatās info I could just readily share either 
What I do not understand is if they do not share info why is all the FW available on the Dropbox and with VEFLASH you can program the EEPROM and then also program the SN into the PIC18Fā¦?
What do they do with all the right off boards? We struggle to get PCB manufacturing going because there is not components available anymore.
1 and 1 do not make sense anymore
Given there openess already I think they have the right to at least some IP. They are brilliant at what they do and if you compare them to others, well.
Just the https://community.victronenergy.com/index.html is a brilliant forum for issue resolution.
They are excellent product to my opinion one of the best.

Itās encrypted. And it isnāt everything. The microcontroller has a separate bootloader that knows how to load the firmware, and you donāt have that, so you cannot program it.
Yes that part I know.
There is bootloader and SW and then on the EEPROM there is FW that control IO interfaces.
If you had everything to make/repair your own boardsā¦ then the counterfeiters would also have everything to make their own boards. So the situation, where you cannot program your own microcontroller, is entirely due to the existence of counterfeiters.

Agree totally that why will trouble shoot on what I currently got with me.
The only thing would be if parts was bit more available with less red tape but I also understand IP and existence of companies and products with work security.
