Allwinner a33 sdk Pc#
If anyone else is interested I can create a fork on github.Download the Firmware or Flash file for your Allwinner A33 Tablet PC with tools needed to perform the flashing. Has anyone else gotten a chance to play around with this board? I'm going to try and get the camera and battery working in the next week or so. The /sys/class/power_supply directory exists, but the /sys/class/power_supply/battery directory is missing.
Allwinner a33 sdk how to#
So far the wifi works, but I haven't figured out how to read a connected battery. This weekend I got an ubuntu server image with a mainline kernel working using the armbian build system. The battery connector is terrible, but once connected, the AXP223 also works as expected. Using one of sinvoip's ubuntu images, the the ov5640 camera seems to work. The board comes with 512MB but I think the chip can handle 1GB. I've been playing around with one of these and so far it works pretty well. This setup looks promising, especially since the A33/R18 is pretty cheap. Our basic requirements are support for a decent camera, battery/charge controller, and wifi. I'm looking for a development board to use as a prototype/template for a potential commercial product. I don't associate anything with high (performance) in its name with this device. If it's like H3 then it's a few MB/s less if it's 1st gen behaviour it's a lot slower. To see how OTG behaves a simple storage benchmark should suffice. Ok, let's calm down and wait what we get. But no idea whether A33 is here comparable to H3 or 1st gen (it seems Icenowy simply took all the Cedrus patches for A13 to get video engine working with A33 so at least in this area A33/R16 seem to be compatible to '1st gen Allwinner SoCs'). I thought there would be differences between first gen OTG ports (A10, A20 and A13/R8) and more recent implementation like on H3 (there I tested this extensively and OTG port used as host port is just a little bit slower while being pretty stable). Well, this type of OTG (if it's not like on Pine64 where you can switch between OTG and HCI controllers behind the USB PHY) in host may work unstable at high data rates (I remember such reports with Lime2 boards and mainline kernel) not being able to use an external aerial unless you desolder components on the board), when they release (hopefully accurate) schematics, how the battery connector looks like and whether this device will be priced competitively.Įdit: According to the above pictures the same DRAM as on NanoPi Air is used (512MiB K4B4G1646Q-BCK0 DDR3) and at least not the ultra-slow eMMC they used on every other board since BPi M2+ (there they use KLM8G1WEMB-B031 - can't read the exact writing on the picture above)Įdit 2: According to linux-sunxi IRC Ampak AP6212 is used on the board (WiFi/BT combo like on nearly all other Banana boards and also NanoPi Air or the upcoming OPi Zero 2 - so we then have 3 flat and lightweight boards with eMMC, camera connector and the same Wi-Fi/BT combination but from 3 different companies using 3 different Allwinner SoCs. Let's see whether SinoVoip manages to introduce the usual design flaws (eg. So most probably no need to fiddle around with Allwinner's tinalinux stuff or SinoVoip OS images at allįor me personally such an R16 IoT board has one big advantage over el cheapo H2+/H3 boards: PMIC support and therefore the ability to use/charge a connected battery (and also control voltage/useage and act on accordingly). (seems Icenowy also managed to get Allwinner video engine working with mainline kernel already). Surprisingly they also rely on their own proprietary LiveSuit image format no one on this planet outside of Allwinner wants to use).īut the good news is: There are some mainline kernel branches with patches for A33 around that are in a pretty good shape eg.

Their tinalinux approach combines this with an outdated Android 4.4 and somehow also a smelly OpenWRT version for reasons unknown to me. Just FYI: the first interesting Banana board since ages: BPi R16 based on Allwinner's A33 SoC (R16 is just a relabeled A33 with a different Allwinner business unit being responsible for).įor R16 exists a horribly outdated 'SDK' made by Allwinner's BU5: (relies on unpatched kernel 3.4.39 which might contain more security flaws than features in the meantime.
