Currently I'm using the IMX8MMini EVK board, but I think the other lines have the same mechanism
1. Has anyone explained me the mechanism of action of Vselect?
How to detect 1.8V or 3.3V memory card without hardware pins?
2. Can you give me a specific example of the name Micro SD 1.8V?

I want to verify if the 1.8V card is inserted, will NVCC_SD2 become 1.8V or not?


Thanks and Regards,
