    As an assumption, it is possible that u-boot specifies the name of the DTB file, which is not suitable for recent kernels. You can try to force the use of a different DTB (via armbianuEnv.txt) and try to check other DTB options. Sometimes there are "miracles" and someone else's DTB can work.

    denni_isl reacted to NicoD in rtl88x2bu support in Armbian   
    Hi all.
    For my next camping trip I've bought a big USB3 2.4G/5G wifi antenna with the rtl88x2bu chip to have better camping wifi reception.
    It didn't work out of the box in Armbian. I've installed it on all my images manually.
    Question is if this driver can be baked into Armbian? It would save me a lot of work. And maybe many others too?
     
     
    For others who need this driver:
    Go to : sudo armbian-config -> software -> install headers
    Download the zip file : https://github.com/cilynx/rtl88x2BU_WiFi_linux_v5.3.1_27678.20180430_COEX20180427-5959
    Unzip
    You'll also need to install dkms :  sudo apt install dkms
    Then follow the instructions in the readme file in the rtl88... folder
    cd rtl88x2BU_WiFi_linux_v5.3.1_27678.20180430_COEX20180427-5959 VER=$(sed -n 's/\PACKAGE_VERSION="\(.*\)"/\1/p' dkms.conf) sudo rsync -rvhP ./ /usr/src/rtl88x2bu-${VER} sudo dkms add -m rtl88x2bu -v ${VER} sudo dkms build -m rtl88x2bu -v ${VER} sudo dkms install -m rtl88x2bu -v ${VER} sudo modprobe 88x2bu

    That's supported too. You need to change the files extlinux.conf and uenv.ini to make them point to the correct .dtb file(look into dtb folder) for the vim3 with a311d. Works great. I'm running it on an ssd. Greetings.

    This is a good summary of the most useful u-boot commands with some explanations https://docs.embeddedarm.com/U-boot_commands

    denni_isl reacted to chwe in eliminating hardware bloat   
    assuming that nobody uses it cause you don't use it is kind of.. Clearly  a bunch of people don't use GPIOs. Sarcastically 90% of the SBCs will collect dust as soon as 'it's not funny anymore' so they don't even need an SoC..
    As @Igor pointed out.. there are a bunch of SBCs for different use-cases.. Connectors are mostly cheap, so they solder as much as possible on it.. E.g. for the HC1 I would love to have at least an I2C bus and some GPIOs wired out.. (for some DS18b20 ore something like that to monitor the temperature).. If you want performance you'll have to pay for it anyway no matter if there are only a few or a bunch of connectors.. See RK3399 boards..
     
    Something else you've to consider.. you need some storage for the bootloader.. Normally those SoCs can't boot directly from SATA.. you either need an SD-Card, eMMC or SPI flash.. Here as well SD-Card is just the 'most convenient' way of doing it. Not much can go wrong and in case it does.. just reflash it.
