So I reached out to see if an andice labs overlay actually existed but unfortunately no reply and did not find anything close ( may have missed something also ).
Since I now have power to the cape and the BeagleBone is up and running I was able to test using the i2c tools to show both the INA219 and AVR on the I2C bus 0x40 and 0x21.
So I, after doing quite a bit of reading ( so need to do more ) I started to pen out what this one will look like, so right now I have this,
&i2c2 {
ina219: ina219 {
compatible "ti,am335x-bone", "ti,am33xx";
reg = <0x40>;
//shunt-resistor = <100000>; // R100 <example value>
shunt-resistor = <> // TBD need to look at schematic
};
};
Now I do not know how or even if Linux has drivers for the AVR / 328p ( I believe ). Was following this
https://irq5.io/2018/07/24/boot-time-de ... th-u-boot/ and looking at all provided materials provided in this thread to get an idea.
