Firefly AIBOX 3588S - Set up Flatpak to use external disk - LinuxLinks
Having liaised with an engineer from Firefly, there’s no publicly available way of making a bootable microSD card for the AIBOX 3588S in Linux. This is because regular Linux tools for making bootable microSD cards require raw firmware yet the SDK for the AIBOX packages firmware in RK format. Firefly didn’t develop raw firmware for the machine.
The engineer has shared a .bin file with me in the past couple of days which can be written to a microSD card but I’ve not yet tried it, as it’ll either require emptying the eMMC or modify a system file. There’s always the risk of being left without a bootable machine. I had that when the bootloader corrupted previously and the only way to repair the system was to use MASKROM with its inherent risks.
jdPixelUpscaler upscale images per pixel - LinuxLinks
jdPixelUpscaler upscales images by simply replacing one pixel with several of the same color.
For example, if you set the scaling factor to 2, one pixel becomes 2×2 pixels of the same color. No attention is paid to the surrounding pixels or to transitions. For certain graphics (mainly pixel art or similar in very low resolution), this may give better results than other methods.
Command line arguments and a D-Bus interface are provided for automation.
