    Rock PI 4

    Some news: https://wiki.radxa.com/Rockpi4/downloads There is a first Armbian image available.

    Odroid C2 general

    Sounds reasonable. Many people won't need it anyway. If peeking around with DT it would be great to have also entries for PWM and 1wire (just commented out, but known working). I2C should also be prepared... Frpm my experience it is hardcto get correct entries for that periphials unless you are a DT expert

    Help for testing? (T4 / Neo4)

    You got me

    Odroid C2 general

    Damned, I compiled new images for C2 recently, but operating it headless, I never checked USB ports. Network was stable so far, I did not notice any hangups or really bad performance. I can check lines with logic analyzer, in case that helps. Just let me know how I can support debugging (I will need C2 boards soon for next deep sea operation, and it also seems to be a really cool board for Antarctica setup)... Michael

    Help for testing? (T4 / Neo4)

    Hi guys, just wanted to let you know that I have no a Nanopi Neo4 and NanoPC T4 here on my desk. So if you need help in testing, please let me know. If the Neo4 just had a little more RAM - it's a real cute board size, but hot without cooling unit Michael

    Rock PI 4

    Sorry, no link, it was direct contact with the German distributor by phone (and some luck, talking about my specfifc requirements).

    Rock PI 4

    RockPi4 sales start officially today. I got two preproduction run boards, one was clearly not yet optimized in soldering Accoridng to revision printing on silk screen it's the final version being sold. One issue only so far: the M.2 adaptor is from a different board, but works electrically.

    Rock PI 4

    So, to get back to facts, build is running, may take a while. Just compared the RockPI4 with the NanoPC-T4. Seems a good choice for starting, bioth RK808D and RT8211E are the same. Audio circuit is different, the RockPI uses an ES8316 instead of ALC5651. Wifi/BT is at least similar, on the RockPI there is an AP6256, compared to the AP6356 on the T4. IR is missing. Update: NanoPC T4 image compilation succeeded, but fails booting. It starts the BL31, but hangs after two NOTICE lines. BL31 version of original image is different to the one used in NanoPC T4 image. I can post both boot logs, if anyone is interested (good ol' FT232AM works with 1.5MBaud, while Prolific fails )

    Rock PI 4

    Zinq = Xilinx = NoGo. I started with Xilinx FPGAs, but use only Lattice ones nowadays. There are company policies which I don't support at all. Maybe a Mico32?

    Rock PI 4

    Hi Igor, I'm a VHDL programmer mostly, with C on microcontrollers. Bash is out of my reach - too complicated... Honestly, if I can contribute by different means, I will do (and will read that page again, as suggested). Are you sure that there is really no FPGA to be programmed? So far, Michael

    Rock PI 4

    Sir, yes Sir I have a working Armbian developer system, that's not a big deal (even for a noob like me )

    Rock PI 4

    Hi Igor, yes... I know. I have patches prepared for Uboot 2018/Odroid C2, Tony takes already a look on. I'm not a kernel programmer, but willing to test - needing a starting point, i.e. someone to include the RockPi4 into the Armbian development tool. So, instead of pointing me to the general "contribute" page, what would be the best "first step" for me? Michael

    Rock PI 4

    Hi all, a new RK3399 board appeared, it is called RockPi4 I have two of these beasts here already, and they works nicely - I like the small details about it (nice eMMC fixture, all heat plates on the bottom side for simple cooling, and an M.2 PICe slot for my second network card Do you see any chance to get Armbian working on that beast, and if so, what can *I* do (with my limited experience in kernel programming)? Debian is working on it already, in case you need more specific information please let me know. Any help is appreciated. So far, Michael

    Thanks for the fish!

    Hi guys, finally, paper is finished, and for anyone interested it can be found here on the arXiv site Be warned, it concentrates on the physics, not the electronics Michael

    Odroid C2 Uboot saveenv

    Just removed the lines in config, and just left my UART baudrate changes in, which didn't change anything regarding this error message. Seems that Uboot tries to load/save from uSD card. Guess I wait a day or so - I tried to understand the defines, but they seem quite complicated.
