First boot with Olimex-made Armbian-based Linux images Applies to Olimex RK3328-SOM-1GB and Olimex RK3328-SOM-2GB and Olimex RK3328-SOM-4GB and Olimex RK3328-SOM-EVB 1. Download archive with the Linux image from here: https://images.olimex.com/release/RK3328-SOM/ For initial tests and if you wish to use desktop environment - get the base image (the minimal image lacks desktop). 2. Extract the archive with the image. It is archived with 7-zip. If you can't extract the image visit the 7-zip site to download the software required for extracting: https://www.7-zip.org/ 3. Download the image to a card. Write the image with USBImager or balenaEtcher on all platforms since unlike other tools, either can validate burning results saving you from corrupted SD card contents. As Armbian suggests: Make sure you use a good, reliable and fast SD card. If you encounter boot or stability troubles in over 95 percent of the time it is either insufficient power supply or related to SD card (bad card, bad card reader, something went wrong when burning the image, card too slow to boot – ‘Class 10’ highly recommended!). Armbian can simply not run on unreliable hardware so checking your SD card with either F3 or H2testw is mandatory if you run in problems. Since counterfeit SD cards are still an issue checking with F3/H2testw directly after purchase is highly recommended. 4. Connect a debug medium to the board. It is recommended to usa a USB-serial adapter cable attached debug pins (RX, TX, GND) but you can also use HDMI or SSH. If you use USB-serial adapter, open a serial terminal on the serial adapter at 1500000 (1.5M) baud, if you use different baud you will get scrambled text over the serial. 5. Apply external 5V DC power to the board. Wait a bit and confirm that boot info is printed on your debug medium. 6. Login with user root and password 1234 (or olimex in older releases).
