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

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? Thanks Chris -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
