Get the total amount of contiguous flash
#include <sys/dcmd_f3s.h> #define DCMD_F3S_ARRAYINFO __DIOTF(_DCMD_F3S, F3S_ARRAYINFO, f3s_arrayinfo_t)
| Argument | Value |
|---|---|
| filedes | A file descriptor that you obtained by opening the device. |
| dcmd | DCMD_F3S_ARRAYINFO |
| dev_data_ptr | A pointer to a f3s_arrayinfo_t structure (see below) |
| n_bytes | sizeof(f3s_arrayinfo_t) |
| dev_info_ptr | NULL |
This command gets the total amount of contiguous flash on the entire chip or contiguous chips.
None.
A pointer to a f3s_arrayinfo_t structure, filled in by the driver:
typedef struct f3s_arrayinfo_s
{
uint32_t status; /* info status */
uint32_t total_size; /* total size of array expressed in bytes */
uint32_t unit_size; /* size of a chip expressed in bytes */
uint32_t chip_size; /* size of a unit expressed in bytes */
}
f3s_arrayinfo_t;
