Peba Posted September 16, 2016 Posted September 16, 2016 http://www.bitkistl.com/2016/08/miqi-sbc-v10-hands-on.htmlhttps://forum.mqmaker.com/t/miqi-use-hw-pack-to-port-other-linux-distros/497 Would it be useful to have armbian on this device ? Best Regards,Peter http://www.bitkistl.com 1
Igor Posted September 17, 2016 Posted September 17, 2016 Yes, if you can do the job of bringing the device into the build system. Since this is a new chip for us, it could not be plain simple. In general we don't have much / (me) any experiences with Rockchip and at least one of us would need to get this device, since porting and supporting without a hardware is no go ... except cloned boards. The chip is powerful / interesting but for the rest I would need to check closely. At least powering with micro USB is not a good idea and I hope there is an alternative way. 1
tkaiser Posted September 17, 2016 Posted September 17, 2016 At least powering with micro USB is not a good idea and I hope there is an alternative way. There is the fan header, Zador found that out by looking at schematic: http://forum.armbian.com/index.php/topic/1095-miqi-is-a-35-single-board-computer-with-rockchip-rk3288/?p=8338 I'm pretty impressed by the performance (and possible tweaks, see at the bottom of this page) but believe it would be necessary to come up with a fully blown desktop Armbian image since here the board seems to perform pretty well (GPU and video acceleration). For headless use cases the lack of IO bandwidth could be a problem. Anyway, I would appreciate if Peter starts with that and would assume Benn Huang could be asked to send out a few more developer samples. 2
Peba Posted January 21, 2017 Author Posted January 21, 2017 There is already a complete build environment based on work done by Linaro(RFS) and Rockchip(kernel). I am not sure if it makes sense to re-invent the wheel ? http://www.bitkistl.com/2016/09/the-rockchip-toolbox.html Last week we got some performance patches from Willy Tarreau (you know - the cluster guy, build farm) With that It was possible to run Kodi, smplayer and some webGL demo at the same time, I just used some of the patches (e.g.set cpu throttling to 80+) http://1wt.eu/miqi/https://forum.mqmaker.com/t/miqi-based-build-farm-finally-up-and-running/605/1 Demo Video: https://youtu.be/DnHJckoxGJU VPU acceleration for Kodi 17 is still WIP, Jacob Chen and Marc aka Mac_l1 started on that. Kernel 4.10+ is available from another guy.https://forum.mqmaker.com/t/mainline-kernel-compilation/572https://github.com/Miouyouyou/MyyQi Anyway I will ask Benn about your proposal for some MiQis :-) Thank You, Peter
zador.blood.stained Posted January 21, 2017 Posted January 21, 2017 There is already a complete build environment based on work done by Linaro(RFS) and Rockchip(kernel). I am not sure if it makes sense to re-invent the wheel ? http://www.bitkistl.com/2016/09/the-rockchip-toolbox.html Well, Armbian (as a build system) is not about reinventing the wheel, but is about supporting a large number of boards and platforms with as little board/platform specific tweaks as possible while compiling from sources as much as possible. If adding a new board/platform requires changes to the build script, there needs to be a good reason to do this. And providing official images for the new platform requires enough hardware samples for the team - some polishing always requires access to the hardware if you don't want to spend weeks instead of hours if relying on somebody else to do the live testing. 1
Igor Posted January 21, 2017 Posted January 21, 2017 I am not sure if it makes sense to re-invent the wheel ? http://www.bitkistl....ip-toolbox.html Main added value of our build system is bringing down the complexity. We could also say: what's written on that page and scattered around various external links (and which require advanced knowledge to understand) is with Armbian summed under one command. 1

jernej Posted January 22, 2017 Posted January 22, 2017 I will get two MiQi boards and I will try to make preliminary Armbian support. 2
Da Alchemist Posted January 23, 2017 Posted January 23, 2017 This board seems tobe interesting, is it possible to buy it somewhere? Regards
manuti Posted January 23, 2017 Posted January 23, 2017 Any chance to have Asus Tinker Board support as spin-off of MiQi armbian?
jernej Posted January 23, 2017 Posted January 23, 2017 Any chance to have Asus Tinker Board support as spin-off of MiQi armbian? Once SoC is supported, adding new boards should be easy. But first, please wait until RK3288 is supported in Armbian. 1
Da Alchemist Posted January 24, 2017 Posted January 24, 2017 Once SoC is supported, adding new boards should be easy. But first, please wait until RK3288 is supported in Armbian. I wonder if the work is necessary because this Board is not really available. The RK is well supported by Linux and SBCs with Rockchip are the more expansiv ones... But in the End Armbian is a non Profit Thing, so supporting Boards is not depending on econnomic Reasons.

Igor Posted February 20, 2017 Posted February 20, 2017 MiQi added to Armbian. What I did: - added kernel 4.4.50 ... took from https://github.com/mqmaker/linux-rockchip(4.4.16) ... and patch all the way up to 4.4.50. - added stock MiQi uboot. I tried too merge it with mainline but figured out soon that it's not going to be easy and abandoned that - added boot scripts with environment file - packaged kernel, u-boot, ... - updated kernel config to meet Docker requirements - added proper serial console - tested CLI and desktop build. Both runs smoothly. Known bugs: random MAC, eMMC install script and boot script need some adjustments Unknown: mali, video accleration librarires, ... etc. most likely those should go: https://github.com/mqmaker/rk-rootfs-build From tomorrow morning, betas will be available here: https://dl.armbian.com/miqi/nightly/ armbianmonitor -uhttp://sprunge.us/TWMFConsole log: -Boot SPL 2016.09-rc1-armbian (Feb 20 2017 - 18:42:37) Trying to boot from MMC2 U-Boot 2016.09-rc1-armbian (Feb 20 2017 - 18:42:37 +0100) Model: rk3288-miqi DRAM: 2 GiB MMC: dwmmc@ff0c0000: 0dwmmc@ff0f0000: 1 *** Warning - bad CRC, using default environment In: serial Out: serial Err: serial miqi init Net: Net Initialization Skipped No ethernet found.

tkaiser Posted February 21, 2017 Posted February 21, 2017 Onboard 16GB eMMC media performances - not the top performer but still very decent. Great work, thanks!

Anyway: I hope Peter jumps in and throws some patches at us (those mentioned above from Willy Tarreau and maybe others to get VPU support and so on)

Myy Posted February 22, 2017 Posted February 22, 2017 Greetings everyone ! Concerning the eMMC, note that one of the patches applied to kernel 4.10.0 just mute the eMMC driver, in order to avoid it spamming the logs with mmc_host mmc1: Bus speed (slot 0) = 50000000Hz (slot req 52000000Hz, actual 50000000HZ div = 0) Discussion about the original patch (not the adaptation) can be found here : http://lists.infradead.org/pipermail/linux-rockchip/2017-January/013621.html Still, if anyone with DTS knowledge could analyse the DTS files and see if the eMMC drivers are not misconfigured, that would be nice. Also, you could see if trimming affect performances by running fstrim before.

See post #4 above or directly http://1wt.eu/miqi/patches-4.9/ (mainline kernel, so this is stuff for next or dev sometimes in the future). No need to hurry, I would believe fixing the eMMC issue with XU4 has higher priority
mdel Posted February 25, 2017 Posted February 25, 2017 @@Igor thx for the benchmarks. those figures are quite impressive for a 32bit soc, it's about 20% higher than my s905 for aes-128 Could you also post the output of /proc/crypto to see if it uses an accelerated engine ? unfortunately i didn't realize that this rk3288 is not one of the cheap ones, so basically you're up for a 65$ board (+20$ shipping) or a 60e tv box.. the 60$+15$ xu4 looks like a better deal. @@tkaiser so igor's board was running at 1800MHz and watching the patch there's a claim it's stable at 1920MHz, but looking at the table i see that : static struct rockchip_cpuclk_rate_table rk3288_cpuclk_rates[] __initdata = { + RK3288_CPUCLK_RATE(2208000000, 1, 3, 1, 3, 3), so i would also run at 2208MHz ?? are those patches specific to the MiQi board, or to the current kernel code published ? (meaning it would apply to any rk3288 board) thx

I think commit messages for the patches answer your question: http://1wt.eu/miqi/patches-4.9/0007-ARM-dts-rockchip-miqi-add-turbo-mode-operating-point.patch http://1wt.eu/miqi/patches-4.9/0006-clk-rockchip-add-all-known-operating-points-to-the-a.patch
willmore Posted February 26, 2017 Posted February 26, 2017 They consider "openssl --speed" to be a good torture test? Oh, my.
