If this is set, the host tries using SPI bus to communicate with slave.

Otherwise, the standarad SD bus is used.

help
|
|
If this is set, the host tries using 4-bit mode to communicate with
|
|
slave. If failed, the communication falls back to 1-bit mode.
|
|
|
|
If this is not set, the host uses 1-bit mode. However, CMD1 is still
|
|
mandatory for interrupts.
|
|
|
|
Note that 4-bit mode is not compatible (by default) if the slave is
|
|
using 3.3V flash which requires a pull-down on the MTDI pin.

default y
|

help
|
|
If this is set, the host tries using high-speed mode to communicate
|
|
with slave. If the slave doesn't support high-speed mode, the
|
|
communication falls back to default-speed mode. If this is not set,
|
|
the host uses DS mode.
|
|
|
|
If the example does not work, please try disabling the HS mode.
