SK-AM64B: Procedure to use the automation header

Tushant Tushant

Part Number: SK-AM64B

I am using starter kit AM64-E3.

We actually ported the automation header and dependency circuitry to our custom board.

I am able to use powerdown, warmreset, and POz but boot mode changing using I2C is not clear at all.

I want to learn the step followed to change the boot mode using automation header.

And want to understand how the IO expander , boot mode buffer and DIP switches work together.

Please guide me.

Can you try toggling the IOs on the IO expander and confirm these wors as expected.

I assume the buffers and IO expander is powered from an always ON supply.

Please share additional information to review.
