Hi,
On our board we are planning to use µSD card as a booting option as well as for storage. In many of the connectors (8 pins) the card detect is multiplexed with D3 (data) line. As the ROM code doesn't supports card detect so during booting it will not be an issue. But during the normal storage can we accomodate the card detect functionality using this multiplexed pin? If yes how?
Will there be any potential drawbacks for not using the card detect pin?
Thanks & Regards,
Nikhil
