I read here something for the orangepi 5 and the orangepi 5 plus. But i has always without anyproblem running the script below. But it looks like PWM is not working or something? Even if i have enabled the option under device-tree-overlay in armbian-config: rk3588-pwm1-m0. orangepi5:pwm:# ls orangepi5:pwm:# I am running this Armbian version: orangepi5:/:# neofetch ##### root@orangepi5 ####### -------------- ##O#O## OS: Armbian 24.11.2 noble aarch64 ####### Host: Orange Pi 5 ########### Kernel: 6.1.75-vendor-rk35xx ############# Uptime: 14 mins ############### Packages: 1055 (dpkg) ################ Shell: zsh 5.9 ################# Terminal: /dev/pts/0 ##################### CPU: (8) @ 1.800GHz ##################### Memory: 1901MiB / 7937MiB ################# What do i wrong? #!/bin/bash if [ ! -d /sys/class/pwm/pwmchip1/pwm0 ]; then echo 0 > /sys/class/pwm/pwmchip1/export fi sleep 1 while [ ! -d /sys/class/pwm/pwmchip1/pwm0 ]; do sleep 1 done ISENABLE=`cat /sys/class/pwm/pwmchip1/pwm0/enable` if [ $ISENABLE -eq 1 ]; then echo 0 > /sys/class/pwm/pwmchip1/pwm0/enable fi echo 50000 > /sys/class/pwm/pwmchip1/pwm0/period echo 1 > /sys/class/pwm/pwmchip1/pwm0/enable # max speed run 60s echo 0 > /sys/class/pwm/pwmchip1/pwm0/duty_cycle sleep 5 echo 50000 > /sys/class/pwm/pwmchip1/pwm0/duty_cycle declare -a CpuTemps=(45000 40000 38000 30000 28000 0) declare -a PwmDutyCycles=(1000 5000 10000 15000 30000) while true do temp=$(cat /sys/class/thermal/thermal_zone0/temp) for i in 0 1 2 3 4 5; do if [ $temp -gt ${CpuTemps[$i]} ]; then DUTY=${PwmDutyCycles[$i]} echo $DUTY > "/sys/class/pwm/pwmchip1/pwm0/duty_cycle"; echo "temp: $temp, target: ${CpuTemps[$i]}, duty: $DUTY" break fi done sleep 1s;

New SSD arrived today. wrote image on it installed the SSD and runs directly! Did also update my SSD to NVME disk and think i broke something. it won't boot even from the USB anymore. Got some errors like can't reset port 1 and a lot more but putty won't save all output. So i think i could make better tomorrow a clean fresh install on the new SSD and restore the files. But all my own fault.

Got the same problem after the last update/upgrade... Can't restore because it hangs and did not get a shell.... done. Begin: Mounting root file system ... Begin: Running /scripts/local-top ... done. Begin: Running /scripts/local-premount ... Scanning for Btrfs filesystems done. Begin: Waiting for root file system ... Begin: Running /scripts/local-block ... done. done. Gave up waiting for root file system device. Common problems: - Boot args (cat /proc/cmdline) - Check rootdelay= (did the system wait long enough?) - Missing modules (cat /proc/modules; ls /dev) ALERT! UUID=db80a2ac-ec37-4fda-91db-92604becfcce does not exist. Dropping to a shell! When i boot in u-boot it looks like it also don't see the nvme drive: => nvme nvme - NVM Express sub-system Usage: nvme scan - scan NVMe devices nvme detail - show details of current NVMe device nvme info - show all available NVMe devices nvme device [dev] - show or set current NVMe device nvme part [dev] - print partition table of one or all NVMe devices nvme read addr blk# cnt - read `cnt' blocks starting at block `blk#' to memory address `addr' nvme write addr blk# cnt - write `cnt' blocks starting at block `blk#' from memory address `addr' => nvme scan => nvme detail => nvme device no nvme devices available => And last update: i puted the nvme drive in a USB3 NVME external drive. And the drive in the USB 3.0 in the USB port and it's just back up and running. I don't know what the nvme broke to work . But i just ordered a new NVME drive because the old one was to small. So a fresh install is also coming maybe it will work again.

So it's now safe to upgrade what i read?
