unused pin for eMMC device of i.MX6

[yuuki]

Dear all,

A eMMC device is connected to SD1 port.
When a system is booted from eMMC on SD1 port, I understand that a CD signal isn't used.
(GPIO_1 pin)

In that case, is it possible to use this pin as GPIO?

Best Regards,
Yuuki

Hello Yuuki,

No, you cannot use the Card Detect pin as a GPIO, even if you connect the eMMC to the SD1 you still need the CD pin to enable the SD1.

Have a great day,
Sergio
