From Legato Reference Manual:
- " WARNING: Because config data can be saved to flash storage, granting write access to a config tree can make it possible for the app to wear out your flash device. Granting an untrusted app write access to another app’s config settings creates a security hole, because it makes it possible for the untrusted app to interfere with the other app’s operation. It’s especially dangerous to grant write access to the system tree, because it’s possible to completely compromise the target device…"
I would like to know where can I find documentation related to flash memory direct access…
I would like to create a partition invisible to users and managed directly by my app to save configuration files and logger data that is not accessible to users. Is this possible?
"NOTE: Directories in the persistent (flash) file system are never made writeable because the on-target flash file system does not support usage quotas (yet) " .
