Hi,

On TUSB9261 Demo board, SPI_CS2_GPIO11 is connected to TPS2560DRC FAULT2Z, the firmware configured SPI_CS2_GPIO11 to input, but I didn't find anywhere in the firmware that handles the power fault if it happens? Is it not handled at all in the firmware?

Thanks,

Amy

Hi Amy,

You are correct. We have the input but it is not handled in the code as there is no good recovery mechanism if the SATA drive is not powered properly. You may implement functionality as you wish.

Regards,
Brian
