MYiR says Android 13 is ready now, a Yocto-based Linux 5.15 image with Qt will become available next month (April 2024), and Ubuntu/Debian images should be ready by May 2024. Sadly, the software is already outdated before launch with Uboot 2018.07, Linux 5.15.104 (March 2022), and the source code for the drivers is also provided to customers.

It’s not the first time we have written about the Allwinner T527 as we quickly mentioned it in our article about the Allwinner A523 tablet processor since at the time we noted it was the same design as the T527 (automotive market) and R828/MR828 (Smart Home market) processors. This also explains why Android 13 is ready before Linux since the tablet market requires Android support.

I guess the bsp is not mainline?

Of course not. Most recent Allwinner BSP is a forward ported mess currently showing version number 5.15.94.

And BTW: this SoC (and its siblings called A523/A527/T523/MR527) cope well with higher clockspeeds, see for example (2.2/1.8 GHz instead of 1.8/1.4)

Sad that the sunxi times are over kind of…

Crazy companies, crazy philosophy, same as stinger: fire and forget.

As usual the HW looks fine.
