Notes/Warnings
- The device must be a SD/MMC device; (for
FSDev_SD_Card_QuerySD(), e.g., “sdcard:0:”; forFSDev_SD_SPI_QuerySD(), e.g., “sd:0:”). - For SD cards, the structure of the CID is defined in the SD Card Association’s “Physical Layer Simplified Specification Version 2.00”, Section 5.1. For MMC cards, the structure of the CID is defined in the JEDEC’s “MultiMediaCard (MMC) Electrical Standard, High Capacity”, Section 8.2.
