#include <sys/dcmd_f3s.h> #define DCMD_F3S_FORMAT __DIOT(_DCMD_F3S, F3S_FORMAT, f3s_format_t)
| Argument | Value |
|---|---|
| filedes | A file descriptor that you obtained by opening the device. |
| dcmd | DCMD_F3S_FORMAT |
| dev_data_ptr | A pointer to a f3s_format_t structure (see below) |
| n_bytes | sizeof(f3s_format_t) |
| dev_info_ptr | NULL |
This command formats a flash filesystem.
A f3s_format_t structure:
typedef struct f3s_format_s
{
uint32_t status; /* format status */
uint32_t offset; /* offset of first unit expressed in bytes */
uint32_t limit; /* limit of last unit expressed in bytes */
uint32_t unit_spare; /* number of spare units */
uint32_t align_pow2; /* alignment power of two */
uint32_t xip_pow2; /* xip power of two */
uint32_t name_length; /* length of name */
/*unit8_t name; root name */
}
f3s_format_t;
None.
