Programming TPS65217B for the first time!

Konstantinos Tsimpoukas

Other Parts Discussed in Thread: AM3359

Hi all I have a board that looks like beaglebone and am3359 EVM from TI (this board is my design)

Both of them they use the TPS65217B PMIC, Normally the TPS65217B is getting programmed from the kernel,

but when you make a new board with new components like me now, the TPS65217B is not programmed and the default

configuration is not fitting my design, So the question is I have to program the PMIC externally for the first time in order

give me for the first time the voltages that i want?

I am asking this because if the pmic TPS65217B is not producing the appropriate values for the proc am3359 to run,

how will be programmed from the drivers of the kernel?

Thanks in advance

Kostas,

The default settings (voltage and sequence) should meet the power up requirements of the AM3359. What setting do you see a problem with?

Thanks for your quick response.

Basically, I have a led connected to pin 1 (ldo2), so there I am waiting a 1.8V.

in LDO1 (pin 3) again 1.8V......

So, if not can it be a connection problem of the chip to the board?

I do not understand your question. Could you provide some more detail? Is this a schematic question? Or are you already testing a board?

Thanks,

Stephen

No it is not a schematic question.

I have already a board and I am testing it.

First I was expecting to put the PMIC on the board and take the voltages as I explained.

Thanks again,

Kostas

Kostas,

I still am not sure what question you are asking. Please be as clear as possible so that I may help.

Stephen
