Does anyone know how to enable the I2C buses exposed on P9 on the Beaglebone AI?  I don't see I2C2 specifically.

debian@beaglebone:~$ sudo i2cdetect -l
i2c-3   i2c             OMAP I2C adapter                        I2C adapter
i2c-0   i2c             OMAP I2C adapter                        I2C adapter

Yes. See my Oct 3 reply in this thread: https://groups.google.com/forum/?fromgroups=#!category-topic/beagleboard/beaglebone-ai/-0BqofMNKVw

I use I2C4 on P9-19,20 to access the config EEPROM on my cape (known as I2C2 on BBB; see BBB SRM sect 8.2)
