https://github.com/victronenergy/venus/wiki/bbb-i2c-(rtc-and-eeprom)
refers to the venus_orig.dts, so it can be patched with code to enable the i2c bus. (this is already done in current versions of bone-venus.
I'm hoping that this could also be modified slightly to turn on at least one of the SPI interfaces, which Victron seem to have omitted from the build.
Any help or suggestions please?
