Table 3 describes in details the meaning of each system or configuration file.
| Artifact | Description |
|---|---|
| FAT | File allocation table. Created upon format operation, either from Uniflash or via Image Programming. FAT is device unique so serial flash devices cannot be cloned and used on another SimpleLink device |
| Reserved blocks | Reserved blocks for future use |
| /sys/servicepack.ucf | Holds firmware patches to all internal cores, Network processor, MAC layer and PHY layer. |
| /tmp/phy.cal | Calibration file created automatically by the device. Calibration is performed sparingly, typically when coming out of Hibernate and only if temperature has changed by more than 20°C or upon power cycle |
| /tmp/fcon.frm | Fast connect frame. Holds all beacon information of the last connected access point. Created upon successful connection to an access point |
| /tmp/fcon.ssid | Fast connect profile. Holds selected profile information of the last connected access point, as if a profile is added by the application through API. Created upon successful connection to an access point. |
| /tmp/table.arp | ARP table file. This file holds up to 8 entries. The table is updated upon ARP response reception to the device IP address |
| /sys/date_time.cfg | Holds the system time and date. Mainly used with to validate expiry time of certificates during SSL connections |
| /sys/rxfltr.ini | Holds all RX filtering information. The Rx-filters module enables you to simply define a set of rules that determine which of the received frames are transferred by the SimpleLink device to the host, and which frames are dropped. The Rx-filters can be activated during AP-connection and during promiscuous mode |
| /sys/infoele.cfg | Holds user defined information element. The information element is transmitted when the device is either in AP mode or Peer2Peer group owner mode. The size is limited to 252 bytes |
| /sys/macadd.bin | Holds the user defined MAC address of the device. If this file exists, the device internal MAC address is bypassed |
| /sys/stacfg.ini | Holds device configuration when it is either in station mode or Peer2Peer client mode. The list of APIs related to stacfg.ini can be found under Host Driver mapping |
| /sys/ap.cfg | Holds device configuration when in access point mode. The list of APIs related to ap.cfg can be found under Host Driver mapping |
| /sys/p2p.cfg | Holds device configuration when Peer2Peer mode (client or group owner). The list of APIs related to p2p.cfg can be found under Host Driver mapping |
| /sys/mode.cfg | Holds device general configuration, unbound to device mode. The list of APIs related to mode.cfg can be found under Host Driver mapping |
| /sys/pref.net | Holds up to 7 stored profiles. Profiles may be stored explicitly from user application or implicitly during Smart Config provisioning. SimpleLink device scan the stored profile list only if connection policy is set to Auto mode |
| /sys/pmcfg.ini | Holds the power policy configuration of the device. The list of APIs related to pmcfg.ini can be found under Host Driver mapping |
| /sys/ipcfg.ini | Hold IP configuration of the device. The list of APIs related to ipcfg.ini can be found under Host Driver mapping |
| /sys/devname.cfg | Holds the device name and URN. The list of APIs related to devname.cfg can be found under Host Driver mapping |
| /sys/dhcpsrv.cfg | Holds DHCP server information. The list of APIs related to dhcpsrv.cfg can be found under Host Driver mapping |
| /sys/httpsrv.cfg | Holds HTTP server information. The list of APIs related to httpsrv.cfg can be found under Host Driver mapping |
| /sys/mdns.cfg | Holds mDNS client information. The list of APIs related to mdns.cfg can be found under Host Driver mapping |
| /sys/smartconfigkeys.cfg | Holds Smart Config keys in case the provisioning procedure is secured (access point credentials are encrypted during provisioning). |
