I am using a TPS65217C in a non-AM335x application, and I need the device to start up with DCDC2 at 3.3V (not 1.1V). This 3.3V will power the processor that controls the I2C to the TPS65217.
I do have the EVM, which I was successfully able to bring up using the GUI. I decided to cut the trace going from the L2 output back to VDCDC2, and I kludged in a voltage divider to take 3.3V down to the vref voltage (0.6V). 270k/60kohm.
Now when I power up, all of the rails are disabled? In the GUI, I switched XADJ2 to '1', the flipped the 'GO' bit, and still nothing.
Am I missing something here? Maybe instead of designing for vref to 0.6V, I should use 1.1V?
