Perfect, that worked!
Thanks,

Hi Cris,
There have been a number of changes in the 1.0-b1 release in how mynewt is
initialized and the documentation hasn’t quite caught up yet. The kernel now
initializes the packages that are specified in pkg.yml automatically as part of
system start up, and that includes the nffs filesystem init code in your main.c.
Your syscfg.yml and pkg.yml files look okay. To be specific, you can remove the
following lines from your code:
/* 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);
}
Hope this helps.

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

*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
