The device must be a SD/MMC device; (for FSDev_SD_Card_QuerySD(), e.g., “sdcard:0:”; for FSDev_SD_SPI_QuerySD(), e.g., “sd:0:”).
For SD cards, the structure of the CSD is defined in the SD Card Association’s “Physical Layer Simplified Specification Version 2.00”, Section 5.3.2 (v1.x and v2.0 standard capacity) or Section 5.3.3. (v2.0 high capacity). For MMC cards, the structure of the CSD is defined in the JEDEC’s “MultiMediaCard (MMC) Electrical Standard, High Capacity”, Section 8.3.
