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();

Hope this helps.
