I'm trying IMXRT1050 evaluation board with a demo on SD card (driver/sdcard/interrupt).
I'm using the following SD card: SD-C02G.
I have this kind of problem: the demo prints ALWAYS "the presence of SD CARD" despite the card is not inserted on the slot.
In any case if SD is inserted before to launch the demo, it's possible to write/read on the card.
It seems ONLY a problem of card detection system.
