MX35 NOR Flash

NuttX provides support for SPI based NOR flashes from MX35 family Supported capacity is up to 2 Gbit (256 MB).

The driver can be enabled by CONFIG_MTD_MX35 option. It is possible to select the SPI mode with CONFIG_MX35_SPIMODE option and communication frequency with CONFIG_MX35_SPIFREQUENCY option.

The size of the flash is set automatically during the device initialization.

The flash memory has to be initialized before used. This is typically done from board support package layer during the board’s bringup phase. This operation is performed by following function.

#include <nuttx/mtd/mtd.h>
