It is also possible to build on OSX. Building firmware directly on a Windows platform is not supported. However, if all you have available is a windows machine then we would recommend to set up a linux based virtual machine. Note: the following build was made on Ubuntu 16.04.5 LTS running 4.15.0-43 kernel. text/html 2023-03-31T10:35:17+03:00 https://wiki.8devices.com/carambola3:connect Connect How to connect to your brand new Carambola3? There are a couple of ways to do this and we do recommend: * Via serial: picocom for Linux and OSX, putty for Windows. * Ethernet: ssh for Linux and OSX, putty for Windows. Serial connectivity is already integrated into Carambola's USB Type C together with power input. That way if you are powering it using USB to USB Type C cable there is nothing else for you to plug in to use serial. text/html 2023-04-03T10:39:26+03:00 https://wiki.8devices.com/carambola3:flash Flash Firmware This section covers a few methods to flash firmware onto your Carambola3. ---------- Web interface / LuCI Connect to your Carambola3's web interface and navigate to (System → Backup / Flash Firmware), then select your firmware image and press Flash image, on the next page click Proceed to begin flashing. text/html 2023-03-31T10:57:59+03:00 https://wiki.8devices.com/carambola3:liveboot Live Boot from USB Carambola3's bootloader (Caraboot) includes a USB boot capability (starting from version 2.0) which supports reading files from USB storage (formatted in FAT32) and using them to boot a Linux image or write to internal flash memory. text/html 2023-03-31T10:50:20+03:00 https://wiki.8devices.com/carambola3:recover Recover Firmware The following section goes into detail of the firmware recovery process for Carambola3 when it does not boot any further than U-Boot.
