Getting a "Card not supported" error when using MicroSD with MK22FN1M0VLL12

Hey there,


I am getting the kStatus_SDMMC_CardNotSupport error when trying to initialize a microSD card on the board we have built that is using the MK22FN1M0VLL12 MCU.

I'll paste the relevant code below so hopefully someone can assist with the issue:

The SD_Init function is where it fails.

SD_SendApplicationCmd is then where it fails next.

Finally, it returns at the if statement there returning kStatus_SDMMC_CardNotSupport.

Can anyone provide any solutions? Thank you for your time.
