Chapter 12. Config Region - Configuration
File Storage
The config region is a flash memory region used to save files in order to maintain data even after hardware resets. The
flatfsd command is used to write data to and read data from the config region.
12.1. Reading from the Config Region
The command shown below is used to read from the config region. The files read from the config region are created under
the

[armadillo ~]# flatfsd -r
Figure 12.1. Reading from the Config Region
In the default software, the files are automatically read out from the config region
at boot time. If the config region data has been damaged, it is replaced with the
contents of the
/etc/default
directory.
12.2. Saving to the Config Region
The command shown below is used to save to the config region. The files saved to the config region are those present
under the /etc/config directory.
[armadillo ~]# flatfsd -s
