TPS65217C in BBB board

Hi experts,

I’ve a Beaglebone black board, TPS65217C power management IC is used on it. My question is about the I2C interface of it.

By default, all power outputs of TPS65217 are off, so there is no 1.1V, 1.5V, 1.8V, etc. which means AM335x needs to configure the I2C interface firstly to enable these power rails, while AM335x is off at this moment, it looks like a endless loop.

Any comments?


They come up in a default mode. No need for the AM3358 to do anything. Check the datasheet of the TPS65217 for more information.


Look again at the tps datasheet. A number of ours are on to support the am335x family.
