FAL API

Find Flash device

const struct fal_flash_dev *fal_flash_device_find(const char *name)

Find Flash Partition

const struct fal_partition *fal_partition_find(const char *name)

Get the partition table

const struct fal_partition *fal_get_partition_table(size_t *len)

Temporarily set the partition table

The default partition table will be automatically loaded when FAL is initialized. Using this setting will temporarily modify the partition table and will lost this setting after restarting

void fal_set_partition_table_temp(struct fal_partition *table, size_t len)

Read data from partition

int fal_partition_read(const struct fal_partition *part, uint32_t addr, uint8_t *buf, size_t size)

Write data to partition

int fal_partition_write(const struct fal_partition *part, uint32_t addr, const uint8_t *buf, size_t size)

Erase partition data

int fal_partition_erase(const struct fal_partition *part, uint32_t addr, size_t size)

Erase the entire partition data

int fal_partition_erase_all(const struct fal_partition *part)

Print partition table

void fal_show_part_table(void)

Create block device

This function can create the corresponding block device according to the specified partition name, so as to mount the file system on the specified partition

struct rt_device *fal_blk_device_create(const char *parition_name)

Create MTD Nor Flash device

This function can create the corresponding MTD Nor Flash device according to the specified partition name, so as to mount the file system on the specified partition

struct rt_device *fal_mtd_nor_device_create(const char *parition_name)

| Parameters | Description | | :------------ | :---------------------------------- ------------------ | | parition_name | Partition name | | return | If the creation is successful, the corresponding MTD Nor Flash device will be returned, otherwise empty |

Create a character device

This function can create the corresponding character device according to the specified partition name to facilitate the operation of the partition through the deivice interface or the devfs interface. After POSIX is turned on, the partition can also be operated through the open/read/write function.

struct rt_device *fal_char_device_create(const char *parition_name)

| Parameters | Description | | :------------ | :---------------------------------- ------- | | parition_name | partition name | | return | If the creation is successful, the corresponding character device will be returned, otherwise empty |
