7th page uploaded in KiCAD https://hellosemi.com/KiCAD_Linux_Boards.html (Still only find the BPi version so far) Thinking first board will be a minimalist square board with SoC 2GB DRAM serial uSD HDMI PMIC SATA USB flash just to get it to boot.

Allwinner VPU kernel driver crowdfunding campaign
by Forest Crossman 29 May '18

29 May '18

I'm suprised this hasn't been posted here yet, considering its relevance to this project: https://bootlin.com/blog/allwinner-vpu-crowdfunding/ The engineers at Bootlin (formerly Free Electrons) are running a crowdfunding campaign to complete the upstream kernel support for the CedarX Video Processing Unit (Allwinner hardware video decoder/encoder). If you're not familiar with Bootlin, they're the ones responsible for a lot of the other mainlining work that's already been done for Alwinner SoCs, so they have experience getting patches integrated upstream and with kernel development in general. They've already reached their funding goal--which includes support for MPEG-2, MPEG-4 part 2/H.263, and MPEG-4 part 10/H.264/AVC decoding on the A20 SoC--but they have a few stretch goals that include support for newer Allwinner SoCs, HEVC/H.265 decoding, and H.264 encoding. Anyways, if any of you want to help fund the development of Free Software, this looks like a pretty good opportunity to do so! For more information, see the Kickstarter campaign here: https://www.kickstarter.com/projects/bootlin/allwinner-vpu-support-in-the-o…

Testing: GPIO
by Richard Wilbur 17 May '18

17 May '18

First, in adding the link to the sunxi wiki page documenting GPIO access on Allwinner chips[1] to the rhombus-tech.net "Testing" wiki page[2], I again triggered the "An error occurred while writing CGI reply" page delivered at URL: http://rhombus-tech.net/cgi-bin/rhombus/ikiwiki.cgi I clicked the "Save" button after editting the ikiwiki code and just waited for it to return. Second, the linux-sunxi wiki page refers to the interaction with the GPIO driver differently depending on whether using linux-mainline or sunxi-3.4 kernel. If memory serves it seems you mentioned we plan to ship the cards with sunxi-3.4 until we get several drivers into linux-mainline, is that so? Sincerely, Richard References: [1] https://linux-sunxi.org/GPIO [2] http://rhombus-tech.net/allwinner_a10/testing/

will lap-top really be 1.1 kg, and how wide
by Chadvellacott 26 Apr '18

26 Apr '18

I noticed that the campaign's main page on "Crowd Supply", says "Only 1.1 kg weight" for the lap-top. Is this specification, still part of the plan? And how wide is the lap-top planned to be (from the left edge of the case, to the right edge, across the key-board)? (I imagine that 15.6 inches is for the screen itself rather than the whole case, and is a diagonal measurement.)

devicetree and testing

If I'm understanding you correctly the 3.4.104 kernel is the most recent kernel to have free support for all the promised functionality of the DS-113, but lacks devicetree support to make that functionality autoconfigurable? That is a beastly spot to be in! In that case I'll make the manual tables from which we can initially code up some tests by using the gpio driver and later write up the devicetree. So, sorry for being a bit thick headed, it just dawned on me what our priorities have to be and why: 1. Hack together some tests under 3.4.104 that we can run on the extant drivers. 2. Work on getting extant A20 drivers mainlined in the linux kernel. 3. Create devicetree for DS113 v2.7.4 and v2.7.5, … (all extant versions of DS113 and microdesktop case). 4. Work on getting devicetree with add/remove overlay support mainlined in the linux kernel (and u-boot?). --Richard

OT: China 12 LED RGBW Par Firmware?
by Alexander Ross 12 Apr '18

12 Apr '18

off topic, idk where else to ask. Photos and additional info about these 12 led rgbw par lights: https://joindiaspora.com/posts/d4c27f80d4c40135bebf0242ac110007 By chance would anyone know where firmware for these cheap china led pars might be? cus i have a few but they all have different firmware. i have 2 versions of the IR remote edition and a non-remote one. I might just get a few more of just single/same edition and be done with it but if i could flash them all with the same firmware that would be great! quite brilliant these little things. floss firmware would make huge potential :). Hoping someone in china might have a clue. I guess the firmware is proprietary or unknown dev but ever hopeful me is :).

OT: verify.sandisk.cn is working?
by Alexander Ross 07 Apr '18

07 Apr '18

Got sd card from china, write speeds are 5mb/s (1gb files i think) using f3 to test capacity. Anyway wanted to verify its genuine but http://verify.sandisk.cn/ doesn’t load for me, not even when using tor. i can access http://sandisk.cn/ If someone whos not too busy. Fancy seeing if it works in china? Else anyone got a recommendation for a no-fee proxy into china? Verify number: 888285238468559181 Thanks
