sdmmc_erase_sectors() function
Erase given number of sectors from the SD/MMC card
Syntax
esp_err_t sdmmc_erase_sectors(sdmmc_card_t* card,
size_t start_sector,
size_t sector_count,
sdmmc_erase_arg_t arg);
Implemented in ![]()
sdmmc_cmd.c:684
Return value
- ESP_OK on success or sector_count equal to 0 - One of the error codes from SDMMC host controller
Notes
When sdmmc_erase_sectors used with cards in SDSPI mode, it was observed that card requires re-init after erase operation.

Description
Read one byte from an SDIO card using IO_RW_DIRECT (CMD52)
Write one byte to an SDIO card using IO_RW_DIRECT (CMD52)
Print information about the card to a stream
Read multiple bytes from an SDIO card using IO_RW_EXTENDED (CMD53) This function performs read operation using CMD53 in byte mode. For block mode, see sdmmc_io_read_blocks. By default OP Code is set (incrementing address). To send CMD53 without this bit, OR the argument `addr` with `SDMMC_IO_FIXED_ADDR`.
Write multiple bytes to an SDIO card using IO_RW_EXTENDED (CMD53) This function performs write operation using CMD53 in byte mode. For block mode, see sdmmc_io_write_blocks. By default OP Code is set (incrementing address). To send CMD53 without this bit, OR the argument `addr` with `SDMMC_IO_FIXED_ADDR`.
Probe and initialize SD/MMC card using given host
Write given number of sectors to SD/MMC card
Read given number of sectors from the SD/MMC card
Check if SD/MMC card supports discard
Read blocks of data from an SDIO card using IO_RW_EXTENDED (CMD53) This function performs read operation using CMD53 in block mode. For byte mode, see sdmmc_io_read_bytes. By default OP Code is set (incrementing address). To send CMD53 without this bit, OR the argument `addr` with `SDMMC_IO_FIXED_ADDR`.
Write blocks of data to an SDIO card using IO_RW_EXTENDED (CMD53) This function performs write operation using CMD53 in block mode. For byte mode, see sdmmc_io_write_bytes. By default OP Code is set (incrementing address). To send CMD53 without this bit, OR the argument `addr` with `SDMMC_IO_FIXED_ADDR`.
Block until an SDIO interrupt is received Slave uses D1 line to signal interrupt condition to the host. This function can be used to wait for the interrupt.
Get status of SD/MMC card
Check if SD/MMC card supports trim
Check if SD/MMC card supports sanitize
Get the data of CIS region of an SDIO card. You may provide a buffer not sufficient to store all the CIS data. In this case, this function stores as much data into your buffer as possible. Also, this function will try to get and return the size required for you.
Sanitize the data that was unmapped by a Discard command
Erase complete SD/MMC card
Enable SDIO interrupt in the SDMMC host
