Building a setup which will provide running different tests manually or by Robot Framework Test Suites.
- DUT should be accessable online
- The SD Card of the DUT should be accessable online in order to be burned with needed image files (.img)
- The DUT should be turned ON/OFF remotely to ensure new load of SD Card with new image

Implemented solution:
-
DUT should be accessable online:
- DUT is member of the ZeroTier Network with the IP: 192.168.193.109
-
The SD Card of the DUT should be accessable online in order to be burned with needed image files (.img)
-
The SD card is inserted in the USD SD Mux device which provides two connections, to the HOST and to the DUT
Host is accessable online:ssh thinedge@sikahq.myddns.me
(ssh public key needs to be provided)ssh 192.168.193.87
over ZeroTier network, the Machine that runs the test must be member of the ZeroTier network as well.
-
Switching the SD card is done by running following commands:
sudo venv/bin/usbsdmux /dev/sg0 dut
to use it with the DUTsudo venv/bin/usbsdmux /dev/sg0 host
to use it with the Host
-
-
The DUT should be turned ON/OFF remotely to ensure new load of SD Card with new image
- Tuning the DUT ON and OFF can be done by sending following MQTT messages
mosquitto_pub -h 192.168.193.87 -t cmnd/sonoff_switch /POWER -m "ON"
mosquitto_pub -h 192.168.193.87 -t cmnd/sonoff_switch /POWER -m "OFF"
- Tuning the DUT ON and OFF can be done by sending following MQTT messages
-
Creating backup image of the SD Card:
- Identify the SD Card
lsblk
- Look for a device that matches the size of your SD card. It will typically be something like /dev/sdX (where X is a letter, such as a, b, c, etc.).
- Unmount the SD Card
sudo umount /dev/sda1
&sudo umount /dev/sda2
- Replace /dev/sdX1 with the appropriate partition identifier if it's mounted.
- Create the Backup
sudo dd if=/dev/sda of=~/sdcard_backup.img bs=4M status=progress
- Identify the SD Card
-
Restoring backup image to the SD Card
sudo dd if=~/sdcard_backup.img of=/dev/sda bs=4M status=progress
IMPORTANT:
- The SD Card switch to DUT must be done after the DUT was switched off (after the switch turn it on.
- The Restoring takes longer time than the Backup
