nffs Setup

Q: I’m struggling to find any examples for nffs, especially how do I setup the nffs_area_desc correctly. Where do I set it up in the BSP especially?

A: It’s all taken care of in nffs_pkg_init. As long as the nffs package is included in the project, it should initialize itself. A few things you might find helpful:

1. The NFFS_FLASH_AREA syscfg setting specifies the flash area that contains the file system.

2. The BSP’s bsp.yml file defines all the flash areas in the system, including the one specified in “1.” above.
