Following is a file system breakdown:

  • File System FAT: 3 blocks
  • Reserved blocks: 2 blocks
  • ServicePack: 66 blocks
  • System files: 22 blocks
  • Configuration files: 28 blocks

Table 3 describes all configuration files.

Table 3. Configuration Files

Filename Description Fail-Safe #Blobks
/sys/macadd.bin MAC address true 2
/sys/stacfg.ini Station configuration true 2
/sys/ap.cfg AP configuration true 2
/sys/p2p.cfg Peer2Peer configuration true 2
/sys/mode.cfg WLAN Mode true 2
/sys/pref.net Preferred networks true 4
/sys/pmcfg.ini Power Management true 2
/sys/ipcfg.ini IP configuration true 2
/sys/devname.cfg Device Name true 2
/sys/dhcpsrv.cfg DHCP Server configuration true 2
/sys/httpsrv.cfg HTTP Server configuration true 2
/sys/mdns.cfg mDNS configuration true 2
/sys/smartconfigkeys.cfg SmartConfig Keys true 2
TOTAL 28

It is highly important to realize that not all system and configuration files are mandatory for a proper device operation. It is use case dependent. While it is easier to understand whether a configuration file is eventually used ot not, it is less obvious with system files. This is the reason why it is mandatory to keep the entire 22 blocks space for system files. Actually, this space is allocated as part of the Image creation procedure and cannot be altered by the user.
