Dear team,

 

I would like to ask about SD Card detection on i.MX8M Mini-EVK.

At i.MX8M mini-EVK(i.MX 8M Mini LPDDR4 EVK),
It seems that overvoltage monitoring (?) Of USB2 is performed by setting SD2_CD_B to GPIO2_IO12.
On the other hand, it looks as if the SD card insertion detection is performed by GPIO1_IO15 (set to GPIO1_IO15).
The SD2_CD_B (SD card insertion detection) function can be assigned as it is, but why dare you use another GPIO?

 

Best Regards,

Miyamoto
