DCMD_F3S_ARRAYINFO

Get the total amount of contiguous flash

Synopsis:

#include <sys/dcmd_f3s.h>

#define DCMD_F3S_ARRAYINFO __DIOTF(_DCMD_F3S, F3S_ARRAYINFO, f3s_arrayinfo_t)

Arguments to devctl():

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

Description:

This command gets the total amount of contiguous flash on the entire chip or contiguous chips.

Input:

None.

Output:

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;
