MIPS Creator CI20 - Debian 8 beta image

Last week Imagination Technologies announced that the CI20 microcomputer is getting an update to Debian 8, with a modern Linux kernel 3.18, and major driver updates to the PowerVR graphics and Wi-Fi firmware, along with changes to the NAND memory driver. The announcement piqued my interest in the CI20 again.

The Debian 8 distribution is currently in beta, and has some issues including the lack of video hardware acceleration support for video players and audio recording. The beta is available on elinux’s website. To overwrite the onboard NAND memory, first write the beta image to a 32GB SD card. You need to change the boot_sl switch on the board to cover Pins 2 and 3, and then insert the SD card in the CI20. The board’s LED momentarily flashes red, then goes off a second, and then turns blue. This indicates that the image is being written to the NAND memory. After about 11 minutes, the LED turns back to red. This indicates the writing process has been completed. All very straightforward.
