SST39VF NOR Flash

NuttX provides support for NOR flashes from SST39VF family Supported capacity is up to 32 Mbit (4 MB).

The driver assumes the device is present at the configured memory address. This address is configurable by CONFIG_SST39VF_BASE_ADDRESS. The driver itself is enabled by CONFIG_SST39FV, mind the typo in the option name.

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>

FAR struct mtd_dev_s *sst39vf_initialize(void)
