Allwinner T5 Processor to Power Android 10 and Linux Multi-Camera Infotainment Systems

Allwinner T-series processors are designed for transportation applications such as automotive infotainment systems, smart rear-view mirrors, and navigation systems.

The Zhuhai-based company has now added a new T-series processor to its website with Allwinner T5 processor featuring four Cortex-A53 cores and a Mali-G31 MP2 GPU that’s a nice upgrade to the Mali-400 MP2/4 GPUs used in their other automotive processors.

Application Block Diagram

Allwinner T5 shares many of the same features and specifications as Allwinner H616 TV box SoC, but it’s a more advanced and larger chip that adds support for LVDS and RGB displays, multiple camera support, wide operating temperature range, and AEC-Q100 qualification. It does without some of the TV box-specific features such as high dynamic range.

Allwinner T5 should be found in IVI (In-Vehicle Infotainment), digital clusters, HD AVM (Automatic Vehicle Monitoring) systems, HUD (Heap Up Display), and other intelligent cockpit products running either Android 10 or Linux as the company offers BSPs for both operating systems.

I could not find products powered by the new processor yet, except for a demo of an Android 10 car radio connected to two cameras. More details may be found on the processor’s product page.

Thanks to Théo for the tip.

Amusing to think about embedding this in a car considering that the vendor is not exactly known for deploying great efforts to support mainline and instead usually distributes BSPs which receive little to no updates, and counts on the linux-sunxi community to do the mainlining for them. I easily imagine driving a car like that in 5 years, and seeing a 3.4.39 kernel (or maybe 3.10.65 if they wanted to live dangerously)…

I really have no idea and just asking out of curiosity, are there infotainment systems which provide up-to-date mainline kernel for cars?

It’s for Android, not Linux though…

Sure, but that doesn’t remove the need to apply bug fixes, which is rarely done in these areas.

I guess this will be AOSP based.. so it’ll run whatever kernel can just about run Android 10 until the end of time.

If it was normal Android then Google seems to be trying to actually make vendors ship updates. So maybe it would get one or two LTS kernel releases before being abandoned. :p

Every headunit have a bit older kernels, but it’s not that bad.
PX3 – PX6 headunits are running on 4.4 kernel, but PX6 is basically RK3399, so this one actually can run on mainline kernel. But for example, from latest allwinner BSP’s and SDKs, this one probably runs 4.9 kernel, since some latest AW SoCs having this kernel version.

What is “posterior occipital panel”, “psi”, “tsc”. “scr” ?

Wonder if USB3 and PCI are too expensive. I feel they are a must in 2020.
