This is a decent set of interfaces, rivaling what we’d expect out of a Pi Zero! As such, it’s very capable of running Linux, and even sports an HDMI output! Taking a closer look at the devboard picture, we can spot traces for three USB 2.0 ports, what seems to be two SDIO interfaces for MicroSD or WiFi cards, and an Ethernet MagJack with its termination network. The build image works on several of my A33 tablets, but gets stuck on the loading screen on some others.Today’s Diminutive Device is a small castellated System-On-Module (Twitter link, nitter proxy) from called M-Core, with a quad-core A53 CPU and 1 GB of RAM. You may need to replace the 圓 sys_config.fex with an appropriate fex for your A33 tablet. I was able to succesfully build the SDK on Ubuntu 12.04 (after installing dependencies and java) and burn it to an SDCard using PhoenixCard and have it run on an A33 tablet. You will need to install the Baidu Yun Guanjia download manager in order to download the files.
A33 Development Materials (Sources: )Ī33 will officially support Android 4.4 and above from AllWinner, so no official multi-OS support like some other higher-end AllWinner SoCs.īelow are links on pan baidu for the original A33 SDK.
