Hi All,
I'm trying to get NFFS working in my project but I'm not having any luck.
The *BSP* *syscfg.yml* file has this included:
syscfg.vals:
CONFIG_FCB_FLASH_AREA: FLASH_AREA_NFFS
REBOOT_LOG_FLASH_AREA: FLASH_AREA_REBOOT_LOG
NFFS_FLASH_AREA: FLASH_AREA_NFFS
COREDUMP_FLASH_AREA: FLASH_AREA_IMAGE_1
The *bsp.yml:*
bsp.flash_map:
areas:
# System areas.
FLASH_AREA_BOOTLOADER:
device: 0
offset: 0x00000000
size: 16kB
FLASH_AREA_IMAGE_0:
device: 0
offset: 0x00008000
size: 232kB
FLASH_AREA_IMAGE_1:
device: 0
offset: 0x00042000
size: 232kB
FLASH_AREA_IMAGE_SCRATCH:
device: 0
offset: 0x0007c000
size: 4kB
# User areas.
FLASH_AREA_REBOOT_LOG:
user_id: 0
device: 0
offset: 0x00004000
size: 16kB
FLASH_AREA_NFFS:
user_id: 1
device: 0
offset: 0x0007d000
size: 12kB
*APP **syscfg.yml* has this line:
CONFIG_NFFS: 1
*APP **pkg.yml:*
pkg.deps.CONFIG_NFFS:
- "@apache-mynewt-core/fs/nffs"
In my main.c I have included the headers and added the sample code to
initialize NFFS :
#include "nffs/nffs.h"
#include "fs/fs.h"
/* NFFS_AREA_MAX is defined in the BSP-specified bsp.h header file. */
struct nffs_area_desc descs[NFFS_AREA_MAX];
/* Initialize nffs's internal state. */
rc = nffs_init();
assert(rc == 0);
/* Convert the set of flash blocks we intend to use for nffs into
an array
* of nffs area descriptors.
*/
cnt = NFFS_AREA_MAX;
rc = flash_area_to_nffs_desc(FLASH_AREA_NFFS, &cnt, descs);
assert(rc == 0);
/* Attempt to restore an existing nffs file system from flash. */
if (nffs_detect(descs) == FS_ECORRUPT) {
/* No valid nffs instance detected; format a new one. */
rc = nffs_format(descs);
assert(rc == 0);
}
rc = fsutil_write_file("/test", "255", 3);
if (rc != 0) {
}
I'm getting this compile error:
*Compiling main.c**
**Error: main.c: In function 'main':**
**main.c:392:5: error: implicit declaration of function

**cc1: all warnings being treated as errors*
I did a search for "flash_area_to_nffs_desc" and I can't find a
declaration for it anywhere in the repo.
Anyone have any ideas on why I'm getting these compile errors?
Thanks,
Cris
