Hi, Our Debian-style package builds logs for RPB, 96boards and linaro builds are now available on repo.linaro.org. Previously build logs were available in jenkins, but they expired in 30 days from build. Now build logs are located in the same directory as the packages - for example qemu, you would find the logs for qemu builds in http://repo.linaro.org/ubuntu/linaro-overlay/pool/main/q/qemu/ directory. The build logs are also broadcast via the packages mailing list: https://lists.linaro.org/pipermail/packages/

Failed to boot kernel with u-boot on hikey

by Liming Wang

Hi all, I'm trying to boot kernel with u-boot on a hikey board(lemaker version). I followed the steps of u-boot/board/hisilicon/hikey/README and everything is OK except the kernel hangs at "Starting kernel ..." I used the latest Image and hi6220-hikey.dtb from [1]. And boot log is attached. I don't know whether there is anything block the kernel to boot. Thanks, Liming Wang 1. https://builds.96boards.org/snapshots/hikey/linaro/debian/latest/

24-hour stress test

by Chase Qi

Hi Amit, Ricardo and Dev, I have created a shell script[1] to do stress test for 96boards Linux build. The current script supports stress_ng, stress_network and stress_oom. I will investigate how to stress suspend/resume once it is supported. Would you please give the script a review? Any comments will be appreciated. Test log examples attached. The following bugs have been found. Bug 317 - [RPB] stress-ng reboots HiKey board within 10 minutes Bug 318 - [RPB] system hangs after "ip link set wlan0 up" executed Bug 272 - periodic 10-15sec wifi connectivity loss Thanks, Chase [1] https://git.linaro.org/people/chase.qi/24h-stress-test.git/tree

Newbie question: Unable to boot

by Michael Eager

I have an HiKey Early Access Board which I assume is made by CircuitCo. I have connected it to a HDMI display and USB keyboard/mouse. When I plug in a 12v PS, and click on the power button, after a few seconds LED 1 lights and stays on, LED 0 flashes a couple times and goes out. Nothing else happens. I don't get any signal to the display. Am I doing something wrong? Any suggestions? -- Michael Eager eager(a)eagercon.com 1960 Park Blvd., Palo Alto, CA 94306 650-325-8077

What's new? What's old?

by Thomas B. Rücker

Hi, So, LC BKK came and went, and now I'm back, sounding like a broken record: - Compliance report: HiKey (CCo) - Compliance report: HiKey (LeMaker) - Compliance report: Dragonboard410c - Compliance report: Bubblegum - Compliance report: Cello - Compliance report: Husky - Compliance Check-List - Other latest work (cf. mail on this list 2016-02-05T11:11) - Anything of significance at LCBKK? Please. If anyone has /any/ doubt about why I'm asking for all those compliance reports: "Once a compliance report has been approved the vendor may use the 96Boards branding and logo according to published terms and conditions, and the vendor product will be added to the 96Boards website(s)." -- http://www.96boards.org/compliance/#Compliance All boards mentioned above are on the website and their vendors show the "96Boards branding and logo". So with all due respect and excuse my french: Reports or GTFO! Cheers Thomas PS: Someone broke a Wordpress plugin on http://96borads.org

Sensors board bootloader

by Grant Likely

Ugh. The rev-c 96Boards Sensors mezzanine got shipped without a bootloader on the ATMEGA. You'll need to flash the bootloader yourself, or return the board to get it reflashed. (I recommend doing it yourself. It's very simple to do). I'm working with Seeed to get the boards shipped from the Seeed Bazaar reflashed. Here are the instructions. Do this with the Sensors board DISCONNECTED from the baseboard. https://www.arduino.cc/en/Tutorial/ArduinoISP Let me know when you've fixed your board. I'm keeping a list. g.

Reference Platform wiki is moving!

by Robert Wolff

Hello everyone, This is a courtesy email regarding *96Boards wiki* and *documentation*. Over the next week *(04/03/16 - 04/09/16)*, we will be transitioning all *Reference Platform *wiki pages and documents to a new home ( *https://github.com/linaro/documentation* <https://github.com/Linaro/documentation>). A freeze on all 96Boards wiki editing permissions has been put into place to avoid complications during the transition process. This decision was made in an effort to simplify the wiki structure. We believe this change with prevent any confusion around the Reference Software and its many hardware platforms. ------------------------------------------------------------------------------------------------------ *Please note:* - This is just for the Reference Platform Project pages - Board Specific documentation will stay on 96Boards wiki all Reference Platform wiki pages will move... >From (Old Location): https://github.com/96boards/documentation <https://github.com/Linaro/documentation> https://github.com/96boards/documentation/wiki/Reference-Platform-Home To (New Location): https://github.com/linaro/documentation <https://github.com/Linaro/documentation> https://github.com/linaro/documentation/wiki/Reference-Platform-Home ------------------------------------------------------------------------------------------------------ For questions, please join the #96boards channel on IRC - freenode, or visit us on the forums <http://www.96boards.org/forums/topic/reference-platform-wiki-is-moving/>.

BREAKING: LINARO to abandon 96boards, remaining board stock to be put on LAVA

by Thomas B. Rücker

==== As ANN TV has learned, LINARO is going to shutter the 96Boards project with immediate effect and refocus on writing ARM software. Remaining stock at manufacturers and distributors is to be bought by LINARO and put in a LAVA cloud project. Engineering resources will be made redundant, management move to a strategy project codenamed "Hootenanny". Internal sources are being quoted, that the failure to produce a coherent and implementable spec which would yield a useable development board was the deciding factor. Despite being in the works for a long time and a lot of internal and even occasional external feedback the spec remains in its original state. It was impossible for manufacturers to come up with even one compliant product, actually most were abandoned in the design stage or right after being announced and never became available. A HW design engineer at one of the board manufacturers went on record "It's as if this spec was written by software people who never held a soldering iron. Let them fix it in software then." He requested to remain anonymous. LINARO management said that the 96borads project was immensely successful, but strategic focus had evolved. When asked to elaborate they added "It may depend on your definition of 'immense' and 'successful'.". ==== Well, I guess that answers some questions - doesn't it?

[LSK4.1-android] USB gadget broken

by Leo Yan

Hi all, I found one bug for enabling Hikey's usb gadget driver; this bug only happen when I use linux-linaro-lsk-v4.1-android but linux-linaro-lsk-v4.1 has no such issue. The detailed info for this bug is: When system bootup, I use configfs to enable ethernet on USB, kernel dumps below backtrace. After narrow down this issue, found below patch introduce this issue: commit 3fdf0dcfea876a0d730da5544f947b0a19c37fdc Author: Badhri Jagan Sridharan <Badhri(a)google.com> Date: Wed Sep 24 18:58:23 2014 -0700 usb: u_ether: Add workqueue as bottom half handler for rx data path u_ether driver passes rx data to network layer and resubmits the request back to usb hardware in interrupt context. Network layer processes rx data by scheduling tasklet. For high throughput scenarios on rx data path driver is spending lot of time in interrupt context due to rx data processing by tasklet and continuous completion and re-submission of the usb requests which results in watchdog bark. Hence move the rx data processing and usb request submission to a workqueue bottom half handler. Change-Id: I316de8e267997137ac189a8b7b2846fa325f4a5a Signed-off-by: Badhri Jagan Sridharan <Badhri(a)google.com> I'm not familiar with USB driver, so want to get some suggestion to fix this issue. BTW, I also searched this patch, but this patch have not been really merged into mainline kernel.
