Hi guys, I am playing with Hikey and I am able to get wifi up and running on 3.18 Linaro kernel base/hikey branch. But I am not able to get it work on 4.4 or mainline. The problem is that st_tty_open is not called that's why it looks like that problem could be with line discipline setup. Do you have any kernel/branch with 4.4+ where BT is working?

HiKey is supported better in v4.7-rc1 vanilla.

by Guodong Xu

Hi, All We now see better support for HiKey in v4.7-rc1 mainline vanilla, and following features landed in v4.7-rc1: dts, configs, pmic, and drm. Features supported from mainline kernel include: - usb otg and host (high-speed mode) - microSD card - uart on Low-speed expansion port (LS) - I2C on LS - SPI on LS - WiFi (need update UEFI to latest, see below for link) Just for your curiosity, in v4.6, we upstreamed: usb & usb phy, (CONFIG_PHY_HI6220_USB), hi655x regulator, hi6220 mailbox, hisi reset, and mmc dw k3. Ref: Build procedure: git checkout -b YOUR-WORKING-BRANCH v4.7-rc1 make ARCH=arm64 defconfig; export LOCALVERSION="-linaro-hikey"; make ARCH=arm64 Image modules hisilicon/hi6220-hikey.dtb -j20; With 1. latest UEFI: (https://builds.96boards.org/snapshots/reference-platform/components/uefi/la…), 2. Debian rootfs: http://builds.96boards.org/snapshots/reference-platform/debian/98/hikey/ Then, replace Image and dtb, you can see v4.7-rc1 running on HiKey. Enjoy! Best regards, Guodong Xu

AOSP seem to have booted up fine on Hikey. See "SystemBroadcastReceiver: Boot has been completed" in your logcat. Did you try connecting hikey to any other HDMI display?

flashing OE RPB artifacts to hikey

by Trevor Woerner

Hi, When I perform an OE RPB build for the DragonBoard410c I end up with the following build artifacts (among others): rpb-console-image-dragonboard-410c.ext4.gz boot-dragonboard-410c.img The *ext4 is flashed to the rootfs partition and the *img is flashed to the boot partition; everything works great. When I perform an OE RPB build for the HiKey I end up with only the following artifact: rpb-console-image-hikey.ext4.gz The instructions I can find[1] and the artifacts from the official download areas[2] suggest I should need something called *.emmc.img.gz, but my build doesn't generate any such file and it doesn't look like the meta-96boards layer provides any recipes for generating any such type of image. It's as though I were missing a step in there somewhere. How do I get an *emmc.img using OE? Is there a way (perhaps using fastboot) to see what partitions have been created on the emmc and their sizes? Best regards, Trevor [1] https://github.com/96boards/documentation/wiki/HiKeyGettingStarted [2] https://builds.96boards.org/releases/hikey/linaro/debian/latest/

usb connection problems

by David Long

I've been having no luck getting low-speed USB devices (i.e.: keyboard and mouse) to work with the 4.4 96boards kernel on hikey. My ethernet dongle works fine though. Is there a known problem or do I maybe just have a config issue? The error messages are: device descriptor read/64, error -71 and device not accepting address 7, error -71 Thanks, -dl

Re: [Dev] 4.4 kernel with HDMI display?

I'm using arch/arm64/configs/defconfig and found no output on HDMI > display. > https://github.com/96boards-hikey/linux/tree/hikey-mainline-rebase-4.4 Hi, Liming HDMI should work. At least, you should be able to see there are Text mode output in the HDMI display, right? (If you didn't see any text output, let me know.) For graphics UI to work, you need to update 'xf86-video-armsoc'. Since in latest hikey-mainline-rebase (-4.4), DRM was updated and name is changed. So, you need git clone and build this in your hikey: # git clone https://github.com/xin3liang/xf86-video-armsoc/ # cd xf86-video-armsoc/ # git checkout hikey-kirin # cat README ; here you need to follow the last three lines to build & install for hikey ... build & install # reboot. -Guodong > > BTW, HDMI works well when I tested 3.18 kernel. > > BR, > Liming Wang

4.4 kernel can't detect sd card on hikey board?

FYI: changed: 96borads compliance web page

by Thomas B. Rücker

I had set up a website watcher a while ago, so that I wouldn't miss any new developments, especially as I was interested in compliance reports becoming available. This change came up about a week ago and as I haven't seen official mentions anywhere, I thought I'd mention it here myself. I, explicitly, do not offer any interpretation or speculation as to the reasons for that change. This is left to LINARO to clarify, if they choose to do so. ================================== changed: 96borads compliance page (http://www.96boards.org/compliance/) --- @ Fri, 22 Apr 2016 00:23:21 +0000 +++ @ Tue, 26 Apr 2016 13:06:51 +0000 @@ -152,11 +152,12 @@ o Bluetooth and WiFi firmware Note that Linux kernel modules must not be provided as binary firmware blobs.

Developer Reference Platform 16.03 differences compared to Debian

by Riku Voipio

One of the goals of RPB is to follow that our changes go back upstream. For the next RPB release, a more polished report is planned. But to get things started, here's a sample - and to use as baseline to compare progress for the 16.06 release. The list of packages is collected from db410/alip image with distrodelta script[1].
