Thank @iav

Hello, I use this patch since many year now, me and my brother, with out it, our helios64 are unstable and unusable... with it, our helios64 work fine for more than two year, my opinion is, push the file in mainline or distrib the file in mainline with a script that install it fast with only one command run as soon has possible when not crash on the boot.. Bye.

Boot on a from scratch helios64 sdcard image, cross fingers and copy / rename / replace original dtb file with ebin-dev file or mount sdcard with scratch helios64 on another computer, do the change, then boot with you ready sdcard on the helios64

Hi SymbiosisSystems, here: But I think you find it 😉

Thank a lot !

Hello, I hope you don't have any problem. Maybe me and my brother have defective or more unstable helios64 than you. Only thing I can say that Prahal share here the specifics files rk3399-kobol-helios64.dtb-6.XX.xx-L2-hs400-opp in this forum since two years ago my helios64 and my brother's helios64 work stable only with it. I back to 6.12.58 Kernel with rk3399-kobol-helios64.dtb-6.12.xx-L2-hs400-opp file and freeze firmware/kernel with armbian-config.

For information: First reboot and crash same that before use rk3399-kobol-helios64.dtb-6.12.xx-L2-hs400-opp. 😞 Back to 6.12.58, rk3399-kobol-helios64.dtb-6.12.xx-L2-hs400-opp and freeze to this setting Me and my brother have helios64 with 6.18.10 Kernel : RAID 10 / LVM / LUKS and crash always when "cryptsetup open..." start Crash when many I/O Crash when use Full CPUs With rk3399-kobol-helios64.dtb-6.12.xx-L2-hs400-opp and Kernel 6.12.58 or 6.12.(XX below): Me, never crash but I reboot often and power off often for personal choice. My brother have uptime upper than 100 or 200 days with problem, freeze or crash Bye

Hi everybody, I running Helios64 with kernel 6.12.58 since a long time and the prahal dtb file rk3399-kobol-helios64.dtb-6.12.xx-L2-hs400-opp and my helios64 work well. Today, Armbian upgrade to 6.18.10 kernel. Is this update use the same change or patch like in rk3399-kobol-helios64.dtb-6.12.xx-L2-hs400-opp ? Is rk3399-kobol-helios64.dtb-6.12.xx-L2-hs400-opp work with 6..18.10 kernel ? Is I must to downgrade to 6.12.58 kernel with rk3399-kobol-helios64.dtb-6.12.xx-L2-hs400-opp and freeze at this kernel version ? Thanks for answer.

Hi, In 2025, Helios64 is now stable for me and for my brother, who also uses it. The only thing to do is, just after installation or after any upgrade, you must reinstall the special file rk3399-kobol-helios64.dtb-6.12.xx-L2-hs400-opp because I think the specific tuning in this file is not included in the official image. For me, I suggest keeping it, using it, and saving your money for other things. Bye.

Hi, my feedback with rk3399-kobol-helios64.dtb-6.12.xx-L2-hs400-opp and agressif fancontrol setting like this: # Helios64 PWM Fan Control Configuration # Temp source : /dev/thermal-cpu INTERVAL=10 FCTEMPS=/sys/devices/platform/p6-fan/hwmon/hwmon6/pwm1=/sys/devices/virtual/thermal/thermal_zone0/hwmon0/temp1_input /sys/devices/platform/p7-fan/hwmon/hwmon5/pwm1=/sys/devices/virtual/thermal/thermal_zone0/hwmon0/temp1_input MINTEMP=/sys/devices/platform/p6-fan/hwmon/hwmon6/pwm1=30 /sys/devices/platform/p7-fan/hwmon/hwmon5/pwm1=30 MAXTEMP=/sys/devices/platform/p6-fan/hwmon/hwmon6/pwm1=50 /sys/devices/platform/p7-fan/hwmon/hwmon5/pwm1=50 MINSTART=/sys/devices/platform/p6-fan/hwmon/hwmon6/pwm1=20 /sys/devices/platform/p7-fan/hwmon/hwmon5/pwm1=20 MINSTOP=/sys/devices/platform/p6-fan/hwmon/hwmon6/pwm1=20 /sys/devices/platform/p7-fan/hwmon/hwmon5/pwm1=20 MINPWM=20 is: All it's Okok Without the tunning file DTB and Fancontrol, the nighmare restart. Today, update, original DTB file restore and CRASH when Luks begin to unciffer my DDs Il restore DTB file and my fancontrol setting and: Return to Okok situation. To conclude, i use my helios without problem when this files is installed. My helios64 always crash if i return to original setting after a update.

Hi, my feedback for fancontrol service here : for 2.5Gbits, i don't use. for rk3399-kobol-helios64.dtb-6.12.xx-L2-hs400-opp, same has i writed up: "It is better to have a good solution in time than a perfect one too late.", my helios64 going to the trash without this workaround.

Hi, To my side, below work in root but not with systemd service: # Helios64 PWM Fan Control Configuration # Temp source : /dev/thermal-cpu #INTERVAL=10 INTERVAL=30 FCTEMPS=/dev/fan-p6/pwm1=/dev/thermal-cpu/temp1_input /dev/fan-p7/pwm1=/dev/thermal-cpu/temp1_input MINTEMP=/dev/fan-p6/pwm1=40 /dev/fan-p7/pwm1=40 MAXTEMP=/dev/fan-p6/pwm1=50 /dev/fan-p7/pwm1=50 MINSTART=/dev/fan-p6/pwm1=20 /dev/fan-p7/pwm1=20 MINSTOP=/dev/fan-p6/pwm1=20 /dev/fan-p7/pwm1=20 MINPWM=20 To my side, below work in root and with systemd service: # Helios64 PWM Fan Control Configuration # Temp source : /dev/thermal-cpu INTERVAL=10 FCTEMPS=/sys/devices/platform/p6-fan/hwmon/hwmon6/pwm1=/sys/devices/virtual/thermal/thermal_zone0/hwmon0/temp1_input /sys/devices/platform/p7-fan/hwmon/hwmon5/pwm1=/sys/devices/virtual/thermal/thermal_zone0/hwmon0/temp1_input MINTEMP=/sys/devices/platform/p6-fan/hwmon/hwmon6/pwm1=40 /sys/devices/platform/p7-fan/hwmon/hwmon5/pwm1=40 MAXTEMP=/sys/devices/platform/p6-fan/hwmon/hwmon6/pwm1=50 /sys/devices/platform/p7-fan/hwmon/hwmon5/pwm1=50 MINSTART=/sys/devices/platform/p6-fan/hwmon/hwmon6/pwm1=20 /sys/devices/platform/p7-fan/hwmon/hwmon5/pwm1=20 MINSTOP=/sys/devices/platform/p6-fan/hwmon/hwmon6/pwm1=20 /sys/devices/platform/p7-fan/hwmon/hwmon5/pwm1=20

For information, fancontrol, deamon or service systemd crash but work just with run fancontrol from shell in root. Seen to be a privileges problem like systemd log... i look this soon and post here my workaround

Hi, Today i upgrade to Armbian Trixie my Helios64 with upgrade from bookworn to trixie, not clean install All seen to be Okok only with use of rk3399-kobol-helios64.dtb-6.12.xx-L2-hs400-opp file inside of original rk3399-kobol-helios64.dtb Only problems for moment are: - fancontrol not seen to work lm75 module... service crash... i will investigate soon if i have the time. - apt show warning with SHA1 checksum or anything i can't investigate for the moment
