    TonyMac32 reacted to mboehmer in Odroid C2 on seafloor (part II)   
    Hi all,
     
    as a small status update on the seafloor business, here are some pictures of the new Odroid C2 based instruments which will be deployed in September/October in the northers Pacific.
    Ten modules with different functionality will be deployed, all based on a standard setup of Odroid C2, TRB3sc FPGA based TDC DAQ system, one PADIWA preamp, and a modded mdedia converter serving as a fully configurable mini switch.
     

     
    One of the modules carries several Hamamatsu mini spectrometers, as well as a camera, to observe bioluminescence.

     
    Another module is targeting at muon tracking with SiPM based readout:

     
    I have some more picture of the more "fancy" PMT based modules, but don't want to flood this forum now with too many pictures.
     
    To all of you: thanks for the support you gave us over the last year, and the discussions on specific topics!
     
    Deployment pictures will follow once the modules are in place on the seafloor, 2600m deep in the Pacific (and operational, hopefully, this time we just have a GbE fiber, no serial port...)
     
    See you, Michael

    TonyMac32 reacted to AnonymousPi in 64x32 LED MATRIX with Allwinner H3 / Orange PI PC   
    A very hackish port exists of this Raspberry PI RGB LED Matrix Library which works for Allwinner H3 devices. This works by bit-banging 14 GPIO pins simultaneously to achieve about a 10Mhz throughput / 100fps refresh rate.
     
    Refer to here: https://github.com/mrfaptastic/opi-allwinner-h3-rgb-led-matrix
     
    I managed to easily get up and running using an Orange PI. Refer to the README of the github repository.

    A simple MOSFET, such AO3402, should do the job ...

    TonyMac32 got a reaction from Werner in Le Potato max power draw on GPIO pins?   
    The GPIO pins are very low current, 3-5 mA if I remember correctly. I don't think you'll damage the SoC, but it certainly won't drive a fan if my memory is correct.

    TonyMac32 got a reaction from Myy in panfrost on RK3288 and GPU on 600MHz problems   
    https://github.com/rockchip-linux/kernel/blob/develop-4.4/arch/arm/boot/dts/rk3288cg-opp.dtsi
     
    is the vendor opps for the rk3288-C (Tinker/chromebook version)
     
    If it isn't a "C", then it wouldn't have 600 MHz Mali or faster than 1.6 GHz CPU according to Rockchip (I don't know about the "W")
     
    @Myy  Wow, that patch is garbage, I didn't even notice that.  It's worse than you are summarizing:
     
    "NPLL is necessary for 500 MHz, ancient krusty kernel suxors and doesn't have this OPP, so in case someone hypothetically someday maybe in theory thinks about possibly re-purposing the NPLL like the ancient kernel did, make mainline suck too for everyone."
     
    Yikes.
     
    I don't see any reason to not reintroduce that OPP for Armbian use, as far as I know this purely hypothetical situation has not taken place.

    OK.  Boots, gets to desktop, plays the test video, sound via HDMI works, my RTL8821CU wifi was properly recognized. 
     
    Only thing I see is no fan control, and the LED is just blinking at 1 Hz for no known reason.
     
    LibreELEC: same, boots, audio, etc.  [edit]  it did not recognize the wifi adapter.
     
    Now to dig up my Ugoos and stuff this on it.

    TonyMac32 reacted to guidol in Very Small Platforms - Rockchip 3308 and Allwinner V3s   
    For Retro-reasons:
    I did buy a old Acme Systems FOX G20 (because it was cheap (10EUR) -
    normally I would like own a Acme Systems Arietta G25 because of the formfactor / pinout).
    The Fox has only 400Mhz and 64MB of Ram (Arietta has 128 or 256MB but same CPU-Speed)
    but could boot a wheezy (Sorry no armbian) in 9MB
    I do find it very cool this very low memory useage - while running the SSH/FTP-Server.
     
    Also I like the company name  
    Reminds me at the companys allways could be seen in Cartoon series
    (ACME Co. = https://en.wikipedia.org/wiki/Acme_Corporation )

    The original image on the companys webpage was "infected" with emdebian wheezy-grip which is long EOL
    So I had to multistrap a new rootfs from the pure debian archive wheezy and transplant the modules/firmware to the newer rootfs (kernel is the same).

    Was something nice to learn here while staying home

    TonyMac32 got a reaction from Igor in Armbian v20.05 (Kagu) Planning Thread   
    I don't see any reason not to, the patchset is a lot of backported stuff anyway.

    I have a cranky Asus board here that kernel panics on boot with our 4.4 (sounds familiar), I might scab the device tree into something mainline likes and skip legacy for the moment.
    @Lanefu, we need to make sure the big patch isn't "undoing" any of the other patches, I got most of it cleaned up, but not all.

    Echoing what Lanefu said, thanks for the info, and sorry about the rough edges!  A new set of sound patches have been submitted upstream, I will take a look at them and see if they can be used as a means of cleaning up our current implementation (targeted originally for 4.19).  
     
    The memory limit seems to be a potential u-boot issue.  For the display, the Amlogic clock framework has been an ongoing project for mainline, with a lot of changes.  I will spend some quality time with everyone's favorite S905X board and get back to you.  🙂

    Well, I don't want to point out something that went wrong, but on the contrary I want to emphasize all the things that went well. Having been disconnected from Armbian for some months, I can see a major improvement in the project's organization. Things like a predictable release cycle, tagged repo with all the releases, scheduling and coordinating, bug tracking... I can see a lot of work has been put into it, and IMO the results are excellent. 
     
    So a big congrats to everyone who took part on it! Great job!

    I think it's unrelated to the packaging of U-boot, probably more the packaging of the kernel.  Or I could be totally wrong, it's late
