Hi yangliu,

You can refer below for general information.

https://www.infineon.com/dgdl/Infineon-AURIX_SD_and_eMMC_Interface-Training-v01_00-EN.pdf?fileId=554...

Besides, TC3xx User Manual Section 46 SD- and eMMC interface has more details about the register and procedure.

for SD cards, 1- or 4- data lines are supported. Block buffer of 2x512 Bytes

However, some exceptions need to be noticed. i.e. no dual voltage, no high clock freq, no 4kB sector support, no DDR, etc... (for eMMC)

Moreover, the file system you should pay attention to write your own.
