    mdrmdr got a reaction from going in 5.15.25 breaks SPI on NanoPi Neo and does not create /dev/spidev0.0   
    Seems to work 😀
     
    /dev/spidev0.0 is created. The SPI device CC1101 and therefore the Homegear gateway initializes fine.
    What else information do you need? dmesg output? Logfiles?
     
    Small change in your instructions: cd deb must be cd deb/nanopineo

    Doing what is explained in this post make it to work but spidev isn't anymore controlled through /boot/armbianEnv.conf file but the DT.
     
    I used the "quick and dirty" fix for now by using "rohm,dh2228fv" which is already in the spidev_dt_ids[] list and avoid me creating a new build with a patch to modify drivers/spi/spidev.c
     
    So basically, I used armian-config to edit the Device Tree (System => Dtc),
    Browse the DT over soc => spi@1c68000
    And I added these lines :
    spi@1c68000 { ... spidev@0x00 { compatible = "rohm,dh2228fv"; spi-max-frequency = <100000000>; reg = <0x00>; }; }  
    And the same for the second SPI controller :
     
    spi@1c69000 { ... spidev@0x00 { compatible = "rohm,dh2228fv"; spi-max-frequency = <100000000>; reg = <0x00>; }; }  
    I also had to remove the spidev stuff from /boot/armbianEnv.conf (No spi-spidev overlay)

    This way, I get two SPI devices and the SBC is working again with 5.15 kernel :
     
    # ls /dev/ | grep spi spidev0.0 spidev1.0

    workaround:
     
    download file from https://imola.armbian.com/beta/pool/main/l/
    install with
     
    sudo dpkg -i FILE.deb  
     
    and DTB package. Headers are optional - if you need to build modules.

    mdrmdr got a reaction from pmayer in Realtek NIC driver dumps on Nano Pi Neo   
    Armbianmonitor: http://ix.io/2y1h Hi all,
     
    I'm new here at the Armbian board. I operate a self made house automation based on a Raspberry using a self written PHP server and Homegear.
    To have a better wireless connection to a differential temperature sensor, I built a Homegear Gateway based on a Nano Pi Neo with Armbian OS and a 868 MHz CC1101 module.
    For the network connection I use a Realtek USB WLAN NIC (Realtek RTL8188EUS-Chipset). Most of the time the gateway works.
    But around 2-3 times per week the gateway hangs and I cannot log on anymore. A hard restart by unplugging power is required.
     
    The only indications I find are 2 dumps of the RTL8188EU driver in kern.log. Check the 2 dumps at the far end of the armbianmonitor output starting at 24.009211.
     
    I already built & installed the 8188EU(S) driver from here and here by myself. But unfortunateley without success.
     
    Anybody any idea whats going on with my gateway?
     
    Thanks a lot for help.
     
    Update: Just had another crash. Maybe someone sees the reason here.
     
    Update: 19.09: Since I cannot create a new answer (what's the reason behind "You have reached the maximum number of posts you can make per day"?), I add it here.
    I just ordered a new NIC with a Ralink 5370 Chipset . Should arrive on monday. I operate the gateway with LAN until then. I'll report how it works with the new NIC.
