Does RT1062 have driver for SD card support in SPI mode

[leoyejiawei]

Hi, I want to use SD card in my own Embedded system based on RT1062, but I only have access to SPI peripheral for my SD slot pinout.

I found in MCUXpresso SDK API Reference Manual Rev.0, there is an SDSPI API in this version, and there was a maintenance record on SDSPI for RT1064 before. But I cannot find this SDSPI API in current version of SDK (2.14.0). I want to know if this API is still somewhere in the SDK? Or how can I use it. Thank you.

Cheers,

Leo

Hi @leoyejiawei 

I hope you are doing great.

You  can use the LSPI peripheral for interfacing an SD Card over SPI.  Altougth  there are some generic kSDSPI enums and defines in the fsl_sdmmc_spec.h i.MX RT1064 EVK SDK 2.14.0, currently there is no dedicated  driver or demo example for this application. 

Still, we have some documentation that migth be useful for you, even if it is not specific for the i.MX RT:

AN2689 Using SDIO with SDHC

AN10406 Accessing SD/MMC card using SPI on LPC2000

Porting FatFs file system to KL26 SPI SD card code

Regarding the online version of the MCUXpresso SDK API Reference Manual. This manual is not from the i.MX RT1064. To consult the online manual for your device navigate to https://mcuxpresso.nxp.com/en/apidoc

I hope this could help!
