Write firmware to SD Card
How to Flash the Firmware to the SD Card¶
You can copy the bootable
images/sdcard.img onto an SD card using "dd":
$ sudo dd if=images/FunKey-sdcard-X.Y.Z.img of=/dev/sdX
Alternatively, you can use the Balena-Etcher graphical tool to burn the image to the SD card safely and on any platform:
Once the SD card is burnt, insert it into the FunKey S console slot, and power it up. Your new system should come up now and start a console on the UART0 serial port and display the RetroFE game launcher on the graphical screen.
How to Update the FunKey S Firmware¶
It is possible to update the FunKey-S over USB, please follow the steps described in the Firmware Upgrade section.
