Download and install the program BalenaEtcher.
Launch the installed BalenaEtcher and choose Select Image from its main menu. Here select the downloaded disk image, it can also be in the archive, as you downloaded it from our website.
After successfully selecting the OS to flash, you have the option to Select target to the right of the OS image selection to choose the appropriate disk drive. Select the drive with the prepared SD card here.
Then just confirm by clicking on Flash!
Maximum caution is essential when selecting a disc drive. Selecting the wrong disk drive would result in data loss on media other than the desired one (SD card).
After flashing, your operating system may detect the SD card in your PC as a new disk drive, which it will not be able to recognize and may ask you to format it. Click Cancel to close this dialog window.
Windows may also notify you that the drive is unaccessible. Also ignore this message.
If you have successfully flashed the image to the SD card, the card will be identified as boot after re-insertion into the PC.
If you have flashed Mervis OS to the SD card, it is possible to perform the last step: enable SSH. The easiest way to do this is to create a file named ssh.txt, or just ssh without the suffix, in the main boot directory of the card. For non-Mervis OS, the SSH connection is enabled by default and does not need to be enabled this way.
At this moment, the OS is safely flashed onto your SD card (with SSH enabled). Unplug the card from your PC, remove it from the adapter (if you used one) and insert the card into your Unipi 1.1.
Insert the card ONLY when the device's power supply is unplugged!
Insert the card into the slot with the back facing up (i.e., the gold connectors facing you). Then plug in device power supply.
Starting the Unipi 1.1 with the newly flashed OS on the SD card will take a little longer - about 3 minutes. This is due to the necessary OS configuration.
