A stable Armbian Bookworm configuration for your Helios64 is provided here (solved). ************************************************************************* Recently a new Armbian 23.08.1 Bookworm image with linux-6.1.50 was made available for Helios64 on its download page (see here) - which is as such great 😀. Everything starts up nicely, but unlike the previous Bookworm 23.05 image, the current one has an issue with accessing USB devices. In the boot process the following error occurs: # cat /var/log/syslog | grep error 2023-09-07T12:31:05.671598+02:00 helios64 kernel: [ 2.537009] dwc3 fe900000.usb: error -ETIMEDOUT: failed to initialize core 2023-09-07T12:31:05.671602+02:00 helios64 kernel: [ 2.537107] dwc3: probe of fe900000.usb failed with error -110 No USB device could be accessed. As this seems to be related to the realtek driver r8152, I compiled and installed the current version of that driver (see below) and after that the USB devices were accessible. # compile and install the current realtek driver git clone https://github.com/wget/realtek-r8152-linux.git cd realtek-r8152-linux... make sudo make install

There are new Armbian 24.05 images available on the Helios64 download page: both images Bookworm minimal and Jammy Desktop are based on linux 6.6.30 (download them !). Again, the rtl_nic firmware (in /lib/firmware/rtl_nic) should be replaced by the version downloaded from git.kernel.org, such that the 2.5G LAN interface works correctly. I would also recommend to copy the dtb attached below to /boot/dtb/rockchip/rk3399-kobol-helios64.dtb (execute 'update-initramfs -u' after that). It includes the 75mV bump of the opp states for the fast cores as suggested by @prahal, it enables the L2 cache info and it enables hs400 speed on emmc again. In particular the 75mV bump has a very positive effect on stability. The bootloader that comes with it would appear to contain the Rockchip DDR blob. It should be fine. If you have an issue with u-boot, just flash linux-u-boot-edge-helios64_22.02.1_arm64 as recommended before. The cpufreq ondemand governor is still the best choice. Good settings are # cat /etc/default/cpufrequtils ENABLE=true MIN_SPEED=600000 MAX_SPEED=1800000 GOVERNOR=ondemand Enjoy. P.S.: If you like a system more responsive to server tasks or push the 2.5G interface to the limits, some fine tuning is helpful. rk3399-kobol-helios64.dtb-6.6.30-L2-hs400-opp
