Door access application does not work for 3.3v Vbus supply

[sanath_rai]

Hi,

I am working on PNEV7462C development board,

I am building my application on Door access application which works with 5V(VBUS )power supply in EVM board.

This application does not work for 3.3v in EVM board.

we have made changes according to UM10883 for 3.3 and 5v system.

Any particular changes to be made in software or hardware?

Regards,

Sanath
