SD card in 1 bit/4 bit transfer mode

[rkhatal369]

Hello Community,

I am working on interfacing sd card with i.MX8MM. 

Is there any sample example or documents available for implementing sd card communication in 1 bit or 4-bit transfer mode?

Thank you!

Best Regards,

Rohit

what do you mean "communication"? if you mean how to set this, you can refer to the Table 6-42. SD/eSD Boot Fusemap of imx8mm reference manual
