Detailed Description

JFFS2 flash device control.

Field Documentation

◆ destroy

rtems_jffs2_flash_destroy rtems_jffs2_flash_control::destroy

Flash destroy operation.

This operation is optional and the pointer may be NULL.

◆ device_identifier

dev_t rtems_jffs2_flash_control::device_identifier

The device identifier of the flash device.

It is used in combination with the inode number to uniquely identify a file system node in the system.

◆ flash_size

uint32_t rtems_jffs2_flash_control::flash_size

The size in bytes of the flash device.

It must be an integral multiple of the block size. The flash device must have at least five blocks.

◆ trigger_garbage_collection

rtems_jffs2_trigger_garbage_collection rtems_jffs2_flash_control::trigger_garbage_collection

Trigger garbage collection operation.

This operation is optional and may be NULL. This operation should wake up a garbage collection thread. The garbage collection thread should use the RTEMS_JFFS2_ON_DEMAND_GARBAGE_COLLECTION IO control to carry out the work.

◆ write_size

uint32_t rtems_jffs2_flash_control::write_size

The size in bytes of the minimum write size for the flash device.

It must be an integral divisor into the block size. This is only applicable for NAND devices.
