Freescale IMX515 Cortex A8 Tablets

Fairly recently, it seems that some of the better-performing aPads coming from China are running on Freescale IMX515 Cortex-A8 processors (ARMv7 variant), with the 8" and 9.7" variants being the most widespread.
There have been some issues on screen shake and sd cards but, this is, all in all a powerful tablet with lots of potential. I'm hoping that this thread attracts some development to go further.

Since the Frescale Source code is easily available I would think there would be more activity here.

I have a mac. How do I install a firmware without recovery mode? I don't have recovery mode, doesn't exist on my unit

[Q] Allwinner a10 vs cortex a9

Hello everyone
I want to buy a budget tablet and of so much research i have found two tablets in my budget
1. Ainol novo 7 tornados
2. Ainol novo 7 advanced 2
The screen size, processor and most of the hardware are same and both run ics. The only difference is that Advanced 2 has a allwinner a10 processor and tornados has amlogic. The allwinner is based on cortex a8 while the amlogic is based on cortex a9. The following site compares them but i am confused that if a8 is better than what is the use of a9. Isnt the cortex a9 successor of cortex a8
Actually i cant post link because of restriction so do a google search for allwinner vs amlogic and click the link of "slate 4 sure blog"
Please recommend me that which one should i buy and is the comparison true.(i.e A8>A9)

Hey...check this website out. i don't know why XDA developers haven't dug into everything Ainol since they're cheap and powerhouses. i would suggest you ask there but in my experience the a9 is a successor and it's much faster. here's the lnk http://www.slatedroid.com/forum/341-ainol-amlogic-cpu-devices/ and there you have all the devices. unfortunately the Advanced 2 is in the upper thread since it's a bit older! I got my Tornados for only 71 USD off of ebay and it regularly ranges to 100 USD...so if you gotta spend the extra couple of bucks for newer software ..then why not...if i helped press the Gracias ( thank you) button

if I could relight this one briefly so I don't create a new thread: can one of you more knowledgeable guys explain to me: for a single core Cortex-A9 implementation like an AW or the AGPtek / WM8850 unit, does it matter much how generous internal memory is? 512mb sounds like enough for such simple design but I do not yet understand how the memory controller manages memory especially to feed the graphics processing unit. for the little cost, i'm prone to want to go "more is better" route: 1GB of internal...

Are both tablets with the same AP? If not then more may not necessarily be better. Let me explain - if one of them has a dual channel memory controller, pick that even if it has lower memory. The reason is that in case of dual channel memory controller the arbitration overhead is lower so memory fetch latency is lower for all components.
If they both have a single channel memory controller, pick the one with the 1GB RAM. Hopefully answers your questions.
As far as how the memory feeds the GPU - usually it is the other way round. It is the GPU that fetches the data from memory. The implementation is very different from GPU to GPU and therefore from AP to AP.

Allwinner has bigger community and 1GB is better!

Allwinner A31 Quad Core Chip Introduction

Recent days,a number of Chinese tablets brand out their quad core tablet.The chip,Allwinner A31,catches a lot of attention.Maybe there is something about A31 you can learn from here.
A31 quad core chip,planned to be used in tablets,smartphones and smart TV field, is presented by Zhuhai Allwinner Technology Corporation in 2012 December.
A31 based on quad core Cortex-A7 CPU architecture and Power VR SGX544MP2 GPU.The GPU has 8 cores and supports 4K and 2K video stream output and encode at the same time.Additionally,A31 configurates dual channel DDR which maximumly supports 64bit DDR3 and dual channel NAND Flash,16bit NAND Flast at most,dramatically improve read-write speed of system memory.What's more,A31 has optimised Power consumption management system,allwinner technology customizes a PMU chip AXP221 for A31,with the help of the AXP221 chip,A31 can efficiently control dynamic power;A31 also packs another special chip for superlow power control,so A31 can achieve long time standby.
The chip doesn't support bluetooth,which probably make some people away from it.

yep, pretty intresting chip there - if the allwinner a10 revolutioned chinese low cost smartphone-tablet market for how cheap it was (it basically created something akin to a market dump in china, with all phone makers jumping ship to allwinner and denying any prehesistent contracts) while being a pos on any other aspect, this one is actually good and fast.
shame tho for the missing bluethooth and gps support, it can be added with external chips but not being integrated in soc meant that really few makers will add them for costs reason.

People all like bluetooth,but it doesn't support it.Shame,shame.
I think some guys who want buy the device with A31 just for the low price.

Advice: MXQ PRO 4K VS scishion v99 Hero?

Hero buying advice needed: MXQ PRO 4K VS Scishion V99? New to android boxes, I'm from London and it seems like there are some boxes which aren't available on UK sites for some reason, so was hoping this is the right place to get advice on the boxes I am looking at.
I am looking to stream content in 1080p (I'm happy with the resolution so don't plan on buying a new tv just yet) and started off looking at cheap £15 boxes on ebay which have 1GB of RAM thinking it would be good enough to stream 1080p. But since I am looking for the best value per £ I decided to look at boxes around the £45 mark:
- £46 SCISHION V99 - hero 64Bit Octa Core Android 5.1 (BT4.0 Dual WiFi) 4GB RAM+32GB TV Box EU, Octa Core,1.5GHz CPU RK3368, GPU PowerVR G6110, Processor ARM Cortex A53
- £45 H96 MAX - H2 TV Box RK3328 Android 7.1 (2.4G + 5G Wi-Fi BT 4.0 4K) 4G RAM+32GB UK PLUG, Quad Core CPU Cortex A53, GPU Mali-450, Processor RK3328.
- £46 MXR PRO 4K 4GB RAM + 32G 64Bit Android 7.1 Quad-core RK3328 2.0GHz Bluetooth Quad-core RK3328 64-bit Cortex A53 and Mali-450 GPU.
- I was also considering: £23 M8S PRO W Android 7.1 Smart TV Box Amlogic S-905W 2GB+16GB Mali-450 4K WIFI OTA, max up to 2.0Ghz, but the price has been varying a bit. I would still consider it if it is better value though (and if it came back down in price a bit) due to it being up to 2.0Ghz? Is 2GB RAM enough to smoothly play 1080p?
1) Should I go for the SCISHION V99 due to the octa core to futureproof? From what I've read no apps take advantage of octa core. Would it help with streaming 1080p? Or should I go for the MXR pro because the seller seems to be saying it is up to 2.0 GHz (although when I googled the chip it said 1.5 GHz?) Help needed with pros and cons, as well as discussion on the GPU/CPU power comparisons?
2) The V99 only has Android 5.1, does that mean eventually all apps will stop being compatible, making the box obsolete? Is there no way whatsoever to upgrade to latest android?
3) I am looking to use as a back up as a mini PC, would I be able to plug in a normal PC USB keyboard and mouse or am I restricted to wireless?
4) If that is the case, I was looking at this and again need advice if it these type of products work well: Black Wireless Keyboard 2.4G Touchpad Handheld Keyboard for PC Android TV UK | eBay
5) These type of small Chinese manufacturers are said to not release updates to firmware (as opposed to amazon fire, chromecast etc) but what does this mean practically speaking? How is this different to being able to update the android version for example?

Help! Whats the difference in performance for these chips?

Hi Tech Gurus,
I'm not the most well verse with tech. Looking for some guidance.
I'm in the market for an external android box for my car. There are 2 options I'm choosing from with the following hardware:
1. Grom VL2: Rockchip 3288 - Quad Core Arm Cortex A17 1.8GHz / Mali-T760 MP4 GPU
2. Lsailt: Allwinner T7 - Hexa Core Arm Cortex A7 1.2GHz / Mali-400 MP4 GPU
Which of these have better performance? 4 big cores vs 6 small cores for a head unit powered by car?
Thanks,
Tech Noob

If you're looking at the processor alone the RK3288 is 50% faster for 33% less cores and it has many improvements over the T7 design. But the speed of the system is very much affected by the amount of memory (RAM). No matter which HU you go with get one that has at least 2GB of RAM.

Both has 3gb of RAM. Thanks for the input. The T7 I believe was released in 2018 while the RK3288 was released in 2014. I thought newer might be better but thanks for confirming that the RK3288 should perform better.
