Here we can only tell what works with main build script from here: (current kernel only).Its not the same board and from what i can tell, usb and emmc doesnt work with this image for this board.
Allwinner A64 Quad Core Soc Software Installation WorksWe only use their standard scripts and application, in fact their relation so that the software installation works OOB.Perhaps you can peek into the schematics to find changesdifferences.With the olimex image (A64-OLinuXino-bionic-base-20200701-182325), USB works fine. The Allwinner a10 was estimated to cost around 7 a few months back and the a13 cost around 5. The A31 is based around four ARM Cortex A7 CPUs and a Power VR SGX544MP2 GPU, all built on TSMCs 40nm G process. In addition theres a fifth power saver (likely A7) core on A31 which has a lower frequency, an arrangement curiously similar to NVIDIAs shadow core this core is likely synthesized for better power efficiency. I asked for details about CPU and GPU clocks since these werent readily available in the launch announcement, and was told that A31 was shipping with the A7s clocked at 1.0 GHz, although the platform could go higher to around 1.2 GHz if an OEM chooses. GPU clocks on the SGX544MP2 are around 350 MHz or higher as well. Allwinner A64 Quad Core Soc Code And DecodeAllwinner also claims to have built its own video encode and decode blocks for the A31 which is what enables the platform to decode UHD (4K) content at 30 FPS. A31 is targeted at tablets, smartphones, TVs, ARM based notebooks, and of course small Android-running media playback boxes. Theres also obviously a Cortex A15-based Allwinner SoC in the works, but no word on how many cores that design will have. Ive started to see Allwinner-based tablets emerge in the US on Amazon and other online retailers built by small one-off device manufacturers, in the future this will likely increase. There also has been an influx of Allwinner-based, Android-running media playback boxes Ive noticed. The Onda V812 which is built around an 8-inch XGA display, includes 2 GB of RAM, 16 GB of storage, 5 MP rear facing camera and 3 MP front facing camera. The Onda V812 is available from some online retailers for 180 USD which is very competitive, construction is aluminum and I was impressed by how well built it felt. I felt like SGX544MP2 was a bit under powered to drive this, but the UI was performant. Curiously enough Onda also claims to have the iPhone 4 camera module for the 5.0 MP rear camera, and 2.0 MP front facing camera. Perhaps the most intriguing part is the 239 price point online. Imported into the US and running stock Android, I feel like price points such as these could easily disrupt some things. Allwinner was quick to remind me that even though A31 and devices are shipping that optimizations are ongoing. It seems like you see too many A10-based and A13-based tablets in the same price ranges as tablets based on the Via WM8850 and Rockchips RK3066, both of which blow the A13 and A10 tablets away (in my hands). To put it another way (ironically the ratios are perfect for this comparison.). The Iphone 3GS has a single core cortex A8, Iphone 4S has a dual core cortex A9. Does anyone who has had both phones think the Iphone 4S is similar in speed to the 3GS. These low end allwinner tablets are being sold for about 41 wholesale, so the bump up in cpu does change the cost significantly. Why get a cheaper iphone especially in places like China when you can get these power beasts alternatives at lowerbetter pricing.
