![]() ![]() So I think the better way would be to use a uboot script to build different device trees based on the menu selection. Stand alone boot seems to have an issue with vc4-fkms-v3d in the device tree and then using llvmpipe, resulting in missing window decorations with kwin_x11. Note: This swapping of fbturbo/v3d seems to only work with my network boot setup. The only difference here is the single kernel parameter nofbturbo that switches between hardware and software rendering on my installation, as posted elsewhere. # Timeout is ignored if only one menu entry.ĪPPEND initrd=/initramfs-linux.img root=LABEL=ROOT_MNJRO nofbturbo rw rootwait console=serial0,115200 console=tt圓 selinux=0 smsc95xx.turbo_mode=N dwc_otg.lpm_enable=0 kgdboc=serial0,115200 elevator=noop usbhid.mousepoll=8 snd-bcm2835.enable_compat_alsa=0 audit=0root=PARTUUID=8b919108-02 rw rootwait console=serial0,115200 console=tt圓 selinux=0 smsc95xx.turbo_mode=N dwc_otg.lpm_enable=0 kgdboc=serial0,115200 elevator=noop usbhid.mousepoll=8 snd-bcm2835.enable_compat_alsa=0 audit=0ĪPPEND initrd=/initramfs-linux.img root=LABEL=ROOT_MNJRO rw rootwait console=serial0,115200 console=tt圓 selinux=0 smsc95xx.turbo_mode=N dwc_otg.lpm_enable=0 kgdboc=serial0,115200 elevator=noop usbhid.mousepoll=8 snd-bcm2835.enable_compat_alsa=0 audit=0root=PARTUUID=8b919108-02 rw rootwait console=serial0,115200 console=tt圓 selinux=0 smsc95xx.turbo_mode=N dwc_otg.lpm_enable=0 kgdboc=serial0,115200 elevator=noop usbhid.mousepoll=8 snd-bcm2835.enable_compat_alsa=0 audit=0 # Timeout is measured in 1/10 of a second. Now create the directory for the menu file: sudo mkdir /boot/extlinux/Īnd finally create the menu file: sudo nano /boot/extlinux/nf The file kernel8.img, is the only file we want from this package, but copy and rename it, as above, so it does not conflict with the linux-rpi4* kernel package.Įdit the /boot/config.txt file and change the kernel= line to: kernel=u-boot.bin $ sudo cp /var/var/pacman/pkg/uboot-raspberrypi*.zst /opt/uboot-raspberrypi/ The file will download to the /var/cache/pacman/pkg/ directory.Ĭreate a directory to store the package contents, I suggest: $ sudo mkdir /opt/uboot-raspberrypi To recap, a simple way to add a boot menu to the rpi4:ĭownload the uboot-raspberrypi package: $ sudo pacman -Sw uboot-raspberrypi
