If this config item is set, format_if_mount_failed will be set to true and the card will be formatted if
|
|
the mount has failed.

help
|
|
Select the bus width of SD or MMC interface.
|
|
Note that even if 1 line mode is used, D3 pin of the SD card must have a pull-up resistor connected.
|
|
Otherwise the card may enter SPI mode, the only way to recover from which is to cycle power to the card.
