Ok, let's keep the name at K970 for now, perhaps no other K970 devices will turn up. The K970 can be found on aliexpress though. > Another point you notices, is the Wifi part.

Try multiple passes for focussing correctly, and try supporting your elbows. Thanks for sticking with this. This could be another solidly supported and properly documented device.

Just to make sure that we have common understanding here. My RTL8723AU reference was meant for the Wifi driver's repository by this name. Support for the bluetooth part is yet another driver. This is all perhaps old stuff, as it is now maintained in mainline linux. I'm working to get mainline linux this going for me to learn about the state of the drivers there. Getting bluetooth more properly going is on my list, and I'll gladly put my findings on the wiki. > Thanks for sticking with this.

Last year, I attended the Linux-Tag and talked to some KDE developer w.r.t. tablets. His advice was to favor to work on Intel-based ones, but my opinion is clearly different here. ARM tablets are the only real thing. Thus I firmly agree, that having another tablet proper is worth the work. --Lars -- You received this message because you are subscribed to the Google Groups "linux-sunxi" group.

Sure. Now that I have a working mainline u-boot, I already planned to turn towards dtb next, to get mainline linux going.

Re: [linux-sunxi] [PATCH] Mainline U-boot -- Tristan Auron Planet 1 tablet
Hi Luc, thank you for reviewing the device description so throughout. I'll work through your comments doing my best to make the description confirm to your standards. > This is an Inet K970??, and like all inet devices this is very often > rebadged. Referring to some of your notes [[Inet K970]]: > As described in the wiki page, please fire up android, and > find out the last 1-2 letters, which usually are tied to a given display > size and wifi module, and use this name everywhere instead. I broke the Android partition while probing ft5x_ts prior starting the device description, so I could not report the Android's bits anymore. Meanwhile I restored the image. Anyway, if you mean the 'Build number', its in the wiki page now, saying: A20_K9701_K9701L2B_1210239.20121030 Otherwise I'm not clear, to what you might refer to by "last 1-2 letters". Another point you notices, is the Wifi part. If possible, please reread what i wrote there: 1) The first link is IMO a proper reference to the relevant Wifi section. 2) The second link refers to a patch making the third USB-head going, to which the RTL8723AU, which is USB-device is connected. So it was not in the fex. If I did something wrong activating it this way, I like know about it. For the OTG, state is as described. W.r.t. OTG the only note on the [[USB]] page is: "On an Hackberry and A20-based tablet (with a single OTG USB port) the main sunxi-3.4 branch kernel (as of 22 Nov 2013) with default defconfig settings also seems to leave USB devices without power. This can be fixed by enabling the Inventra Highspeed Dual Role Controller in Device Drivers -> USB Support and selecting the Allwinner Platform Glue option." By saying "This is standard A20 stuff. Move to the USB page.", do you mean I should not use this options? Otherwise I could file a proper report of the state. For the last points, uart and pictures, this basically a matter of equipment. As this is the first time for me dealing with small electronics and I to check whether my probes and soldering stuff are sharp enough for this purpose. Contrary to the other Inet board pictures in the wiki, i could not locate any writings on the board indicating the uart on the first examination. Thus almost certainly, I'll have to probe them. Most of the pictures have been taken free-hand though with some support with the flash deactivated causing them to become blurry. I'm looking to get a tripod, perhaps this will do better. For the same reason, I did not yet publish a detailed picture of the board and its chips.
