| - | ====== Software updates ====== | ||
| - | |||
| - | The KerOS Distribution supports OPKG packages (embedded version compatible with dpkg packages). | ||
| - | |||
| - | OPKG packages are used to install customer applications and firmware upgrades (the firmware is installed with an OPKG package). OPKG packages use the ''.ipk'' extension. It is strongly recommended to use OPKG packages to deploy binaries/applications since the backup mechanism relies on it. | ||
| - | |||
| - | A package can either be installed using the network or using a USB key. \\ | ||
| - | |||
| - | After each update, the file ''/user/.update'' is appended with the status of the update. Update status can be: | ||
| - | * OK | ||
| - | * PARTIAL | ||
| - | * FAILURE | ||
| - | |||
| - | Error code can be the following: | ||
| - | |||
| - | * ERROR (10) - Downgrade not allowed | ||
| - | * ERROR (11) - unknown error | ||
| - | * ERROR (12) - dependency issue | ||
| - | * ERROR (13) - incompatible architecture | ||
| - | |||
| - | Partial code corresponds to a successful installation that has conflict in configuration files. \\ | ||
| - | This can cause a problem during an upgrade if the configuration files contain new field or value required by the updated software. The partial code warns the user that a manual modification of the configuration could be required, the list of the modified (and the location of the new ) configuration file being listed above the update status (''shadow'' and ''hostapd'' in this example). | ||

| - | __Example:__ | ||
| - | |||
| - | <code> | ||
| - | cat /user/.update | ||
| - | 2017.12.01-14:55:18 -- Update from bscc_v1.13_klk_wifc.ipk: OK | ||
| - | 2017.12.01-14:55:19 -- Update from lorasnmp_v1.13_klk_wifc.ipk: OK | ||
| - | 2017.12.01-14:55:19 -- Update Status : updated 2, failed 0 , partial 0 result : OK | ||
| - | 2017.12.01-15:00:44 -- Update from lorasnmp_v1.12_klk_wifc.ipk: ERROR (10) | ||
| - | 2017.12.01-15:00:44 -- Update from toto_1.0.0_klk_lpbs.ipk: OK | ||
| - | 2017.12.01-15:00:44 -- Update Status : updated 1, failed 1 , partial 0 result : FAILURE | ||
| - | 2017.12.01-15:07:44 Existing conffile /user/rootfs_rw/etc/shadow is different from the conffile in the new package. | ||
| - | The new conffile will be placed at /user/rootfs_rw/etc/shadow-opkg. | ||
| - | Existing conffile /user/rootfs_rw/etc/hostapd.conf is different from the conffile in the new package. | ||
| - | The new conffile will be placed at /user/rootfs_rw/etc/hostapd.conf-opkg. | ||
| - | 2017.12.01-15:07:45 -- Update from keros_3.3-beta2-38-g12943bcb_klk-wifc.ipk: OK | ||
| - | 2017.12.01-15:07:45 -- Update Status : updated 0, failed 0 , partial 1 result : PARTIAL | ||
| - | 2017.12.01-15:12:18 -- Update from lorasnmp.ipk: OK | ||
| - | 2017.12.01-15:12:28 -- Update from keros.ipk: OK | ||
| - | 2017.12.01-15:12:28 -- Update from bscc.ipk: OK | ||
| - | 2017.12.01-15:12:28 -- Update Status : updated 3, failed 0 , partial 0 result : OK | ||
| - | 2017.12.01-15:12:28 -- Firmware restored from backup | ||

| - | <note warning> | ||
| - | Powering off a gateway during a major upgrade will brick it. | ||
| - | </note> | ||
| - | |||
| - | ===== Software update over Network ===== | ||
| - | |||
| - | The following example describes how to trigger an update over network. This example uses a package meant to upgrade the firmware, however, the steps are the same for any other package. | ||
| - | |||
| - | - Transfer the KerOS package corresponding to the new firmware in this directory: <code bash> | ||
| - | # From a computer: | ||
| - | scp keros_2.0.4.ipk root@<ip_address>:/user/.updates/ | ||
| - | </code> | ||
| - | - Ensure file is correctly written: <code bash># On the gateway: | ||
| - | sync </code> | ||
| - | - Trigger Update for next reboot: <code bash>kerosd -u </code> | ||
| - | - Restart: <code bash>reboot</code> | ||
| - | - **This step is specific to firmware updates.** Check the firmware version in the file ''/tmp/sys_startup_status.json'' under the field ''sw_version''. | ||
| - | |||
| - | |||
| - | ===== Software update over USB ===== | ||
| - | |||
| - | The following example describes how to trigger an update over USB key. This example uses a package meant to upgrade the firmware, however, the steps are the same for any other package. | ||
| - | |||
| - | <note warning>For the Wirnet™ iStation, it is necessary to use an accessory to connect the USB stick to the product. It is possible to use either: | ||
| - | * A USB Type C to USB-A adapter | ||
| - | * [[wiki:connect_istation#connect_using_the_debug_probe|A Debug probe]] | ||
| - | </note> | ||
| - | |||
| - | ==== Overview ==== | ||
| - | - Prepare a USB key with the following files: | ||
| - | * ''usb.autorun'': Auto executable script | ||
| - | * ''usbkey.txt'': USB password file | ||
| - | * ''keros_x.y.z.ipk'': the update package | ||
| - | - Plug the USB key on the CPU board. | ||
| - | - Wait for status LED fast blinking. Refer to this [[wiki:peripherals|page]] to know where is status LED on your gateway. | ||
| - | - Unplug the USB key. | ||
| - | - Wait for status LED to be on. | ||
| - | - **This step is specific to firmware updates.** Chek the firmware version in the file ''/tmp/sys_startup_status.json'' under the field ''sw_version''. | ||
| - | ==== Specific files ==== | ||
| - | |||
| - | === usbkey.txt === | ||
| - | |||
| - | ''usbkey.txt'' is a security file. It includes the password of "usbuser" user. \\ | ||
| - | Find information about the usbuser password in the [[wiki:connection_credentials#default_password|credential chapter]]. | ||
| - | |||
| - | In case of consecutive updates on few boards, ''usbkey.txt'' can include multiple passwords (limited to 100). One password per line. | ||
| - | |||
| - | Here is an example of this file for 3 different boards: | ||
| - | |||
| - | ++++ | ||
| - | File to download - usbkey.txt | | ||
| - | <file text usbkey.txt> | ||
| - | USBklkPassword | ||
| - | CustomPassword | ||
| - | 2ndCustomPassword | ||
| - | </file> | ||
| - | ++++ | ||
| - | |||
| - | === usb.autorun === | ||
| - | |||
| - | ''usb.autorun'' is a script automatically executed by the board if the ''usbkey.txt'' file includes a correct password. \\ | ||
| - | Anything can be done in this script but here is an example used to deploy a new firmware or/and new packages: | ||
| - | |||
| - | ++++ | ||
| - | File to download - usb.autorun | | ||
| - | <file bash usb.autorun> | ||
