Download the RV2 image. It's basically the same plus DKMS (including headers) for building the bcmdhd wifi driver. You need to change the "fdt" line in /boot/extlinux/extlinux.conf for rv2->r2s (DTB file is there), e.g before uploading with mount -o offset=$(( 512 * 8192 )) Armbian-....img /mnt/

PCIe is a rabbit hole for it's own. I have a Wifi card that cannot issue in-line-interrupts ("MSI") for some reason so the firmware upload fails, while working fine with same driver in my PC. I simply don't use it. ASPM quirks also seems not to be too uncommon, a simple grep quirk_disable_aspm drivers/pci/quirks.c|wc -l shows 21...

@maxsub with a recent kernel, temp and load should be fine. The exiting question is: all 4 Ethernet ports are working?

Schematics-wise no - at leasts I don't see a diff in the RV2_SCH.pdf. Electrical-wise probably - other traces, so maybe more or less crosstalk, better or worse gnd and such. From a software perspective: this is PCIE-B and C (while A is unused). That PCIe active state power management seems to be a source of endless pleasure, maybe the NVME vendors all have digested the wrong specs or so. Anyhow: if it works now, it's fine probably.

@Curvy Android I don't see meaningful differences in the kernels init msgs for top and bottom PCIe slots - besides that "Buffer I/O error" that leads to the non-working NVME. Besides that, the "faulty power saving mode" line looks familar. I have trouble with my Samsung NVME with that power saving blurb as well. Can you retry with NVME in the top slot and an additional pcie_aspm=off added to your booting SD card in the /boot/extlinux/extlinux.conf file behind append kernel params?

@4A studio You can run the spacemit-gpu-addon.sh on forky. This should install the trixie binaries. If there is something that does not work or wants an unavailable depend, you may try recompiling, the source should be with you: apt-get build-dep somepack and apt-get source -b somepack will get you going. If that works, you can tell me and I'll integrate. @Uhtred2 No 1080p youtube for you? Maybe not every codec works. I have tried with German TV, such as Anyhow, the IMG BXE 2-32 GPU is not very fast, only 500 fish with https://webglsamples.org/aquarium/aquarium.html Hopefully, the K3 successor uses something better. @maxsub You sure use our kernels? Can you post "uname -a" output? I tried the R2S image on my RV2 which shows a zero load with "uptime". Also, why do you need to manually boot USB from uboot? That "kydevtool" together with boot switch does not work either?

Wrote a script to change an Armbian desktop system for Spacemit GPU drivers and Chromium (attached). Tested with the two pre-installed Gnome images on my site (see https://privat-in.de/ goto Downloads). Some testing results: Spacemit offers Ubuntu noble and Debian trixie *.deb from their Bianbu site http://archive.spacemit.com/ For us, main diff here is Noble=chromium (Spacemit customized version) and Trixie=chromium-browser-stable (older and not customized). We need Wayland for the GPU, X11 does not work. With lightdm, each Wayland login freezes. Thus use gdm3. With gdm3, Xfce4 exits immediately, Kde-plasma shows drawing errors, Cinnamon works to some extend, e.g has video placing and window sizing problems. So the only useable GUI is Gnome. With Chromium under Gnome we can watch Youtube with 1080p (video / audio sync should stablize after some seconds). When doing this, CPU temperature is up to 75°C from the ususal 65°C, power is 4 Watts from the ususal 3 Watts. Script should work on other Spacemit K1 boards as well. If you miss some package from Bianbu, write a wishlist or make an PR on https://codeberg.org/sven-ola/spacemit-mirror spacemit-gpu-addon.sh

Addon for @maxsub and the bricked R2S: I tested USB boot from u-boot cmdline on my RV2, and it works. Here's how: usb start setenv devtype usb setenv devnum 0:1 setenv prefix boot/ #setenv fdtfile spacemit/x1_orangepi-r2s.dtb setenv fdtfile spacemit/k1-orangepi-rv2.dtb setenv bootargs "console=ttyS0,115200 root=/dev/sda1" ls ${devtype} ${devnum} ${prefix} load ${devtype} ${devnum} ${ramdisk_addr_r} ${prefix}uInitrd load ${devtype} ${devnum} ${kernel_addr_r} ${prefix}Image load ${devtype} ${devnum} ${fdt_addr_r} ${prefix}dtb/${fdtfile} booti ${kernel_addr_r} ${ramdisk_addr_r} ${fdt_addr_r} In case you have a blank u-boot-env, here's mine attached // HTH printenv.cap

@maxsub You mean the boot.cmd (source for boot.scr) from the Xunlong Ubuntu image for R2S? I'll attach it below // HTH boot.cmd

@maxsub I was not even aware, that boot from USB is a thing. The RV2 boots from SD via extlinux, here is the relevant uboot output.

Success: tested RV2 with GPU on Armbian-noble-nightly. It's a bit hacky but should work. I created a mirror of the relevant packages from Spacmit/Bianbu. Only packages with source, specific to k1x / video / gpu plus chromium. Mirror project is here, in case you want to mirror yourself or miss a package: https://codeberg.org/sven-ola/spacemit-mirror After getting up Armbian-noble-xfce4-nightly on your Spacemit/K1 board (that includes Ky X1) Add mirror repo to /etc/apt/sources.list.d/sven-ola.sources (Note: this is experimental) Types: deb deb-src URIs: https://privat-in.de/armbian Suites: noble Components: main Signed-By: /etc/apt/trusted.gpg.d/sven-ola.gpg Get my repo key with wget -O /etc/apt/trusted.gpg.d/sven-ola.gpg https://privat-in.de/armbian/key.gpg Give the mirror some weight, add an /etc/apt/preferences.d/sven-ola file Package: * Pin: release o=Sven-Ola Pin-Priority: 1000 Install GPU support apt-get update apt-get install img-gpu-powervr apt-get dist-upgrade Note: this will downgrade mesa-25.x to mesa-24.x from Bianbu/Spacemit Install a Wayland-enabled GUI (tested: gnome) apt-get install gnome-core systemctl disable lightdm If asked, select gdm from gnome instead of lightdm from xfce4. After rebooting, click on your user, then stop and select Gnome with the lower right gearwheel icon. I also installed glmark2-es2-wayland to check if that runs. It shows 417@800x600 which is faster than software mesa...

Found the "no Wayland on current kernel" (see new PR https://github.com/armbian/build/pull/9515). glmark2-es2-wayland still reports a 462 score on 800x600. Thus I updated and renamed the image mentioned in previous post with a current 6.18 kernel. You need to switch from 6.6 with /boot/switch-6.18.16-current script, anything else described in the post still is valid. @maxsub Alternatively install a M2(m)-to-M2(e) adapter in the larger bottom M.2 slot and use a NGFF Wifi card, for example RTL8822CE should run

@c0rnelius: Thanks for the info, I'll fiddle with the GPU in the meantime. @Cristian Apas: that hack above is necessary if you use the Xunlong Ubuntu userspace. They have replaced every hint on the OEM, which includes the GPU driver name. Hack not necessary if we simply use the Spacemit Bianbu Ubuntu userspace. I hacked an image together with this (see my site https://privat-in.de goto Downloads). It has a glmark2 score of 424 (not very fast). This is not for everybody. I compiled a standard OrangepiRv2 Armbian image with a legacy kernel and put in a Bianbu 3.01 minimal userspace as root. Details from my notes: # Image creation starts with Armbian-Orangepirv2_trixie_legacy_6.6.99_minimal.img Root from https://archive.spacemit.com/image/k1/version/bianbu/v3.0.1/ -> minimal.img -- Default LANG=zh_CN.UTF-8, change: dpkg-reconfigure locales -> en_US.UTF-8 Copy from Armbian: /etc/netplan/10-dhcp-all-interfaces.yaml, /etc/fstab, /boot/*, /lib/modules/*, /etc/modprobe.d/orangepirv2.conf /etc/modules-load.d/orangepirv2.conf Purge spacemit-flash-dtbs (and thereby remove linux-image-6.6.63*) Uploaded this image to https://privat-in.de/ (Downloads) First steps after flashing UART login as root / bianbu apt-get install parted parted /dev/mmcblk0 (or /dev/nvme0n1): resizepart 1 100% resize2fs /dev/mmcblk0p1 (or /dev/nvme0n1p1) apt-get install gnome-core glmark2-es2-wayland adduser a-new-user adduser a-new-user sudo Reboot and login Click on Terminal, run glmark2-es2-wayland Notes: other Spacemit K1 boards can run Bianbu without any changes, this is exclusively for OpiRV2.

Hi @maxsub, two annotations. Firstly, it's not the Wifi driver but the firmware. Thus echo "options bcmdhd firmware_path=brcm/ nvram_path=brcm/" > /etc/modprobe.d/orangepirv2.conf will get you going. And secondly no, there is no GPU change currently. GPU not working in "current" but may work with dirty tricks using "legacy". That's why it may pay to do some maintenance on the ancient 6.6 kernel.

Status Update: There is already a suitable FW file for Wifi AP mode. It's located in the /lib/firmware/brcm subdir: the newer fw_bcm43456c5_ag.bin can be used by adding firmware_path=brcm/ nvram_path=brcm/ when loading the bcmdhd.ko kernel module. The necessary change is now in Armbian::main. Also, the RV2 legacy 6.6.99 kernel has an advantage: with the Xunlong Ubuntu userspace (from Xunlong image downloads) it supports Wayland and thus GPU when applying the following hack: diff --git a/drivers/gpu/drm/spacemit/spacemit_drm.c b/drivers/gpu/drm/spacemit/spacemit_drm.c index da25ec8b3f..073de3c7ca 100644 --- a/drivers/gpu/drm/spacemit/spacemit_drm.c +++ b/drivers/gpu/drm/spacemit/spacemit_drm.c @@ -23,7 +23,7 @@ #include "spacemit_dmmu.h" #include "spacemit_gem.h" -#define DRIVER_NAME "spacemit" +#define DRIVER_NAME "rvdisplay" #define DRIVER_DESC "Spacemit SoCs' DRM Driver" #define DRIVER_DATE "20231115" #define DRIVER_MAJOR 1 For that reason, we added the LOAD fix also to the legacy/6.6 kernel (thus the uptime output shows a reassuring 0.00). Wayland support for current/6.18 kernel is still under investigation. Also, the edge/7.0 kernel does not boot on the RV2 currently.
