I have installed kernel 5.8 but even /sys/class/pwm is also empty.... Someone more suggestions?

IMHO is 85 celsius really hot. I don´t also know how a big themalpad could work. Is the heatsink warm when you run? Mine have i running really slow and the temperature is arround 32 degrees on normal day with normal load. Full speed about 50 degrees. But i need to say that i have also a heatsink on the CPU from an old Fritzbox router. But even on fullspeed is the fan really quiet and you need to listen very well to here it run. In my opinion is 15 euros a really good deal when i compare with a lot of noisie fans i have. The only problem is that the fan is a little bit big

Very sorry for my always late anwsers. I have my nf-a4x20-5v-pwm directly connected to gnd and 5V pin on the orange pi. The PWM pin do i have connected to pin 7. The RPM pin did i have not connected. I have bought the Noctua in a local internet store for arround €12,- without shipping. The fan is also on full speed so much silent than al the fans i got. I am a really Fanboy now of Noctua I could advice you to buy. more specifications are here https://noctua.at/en/products/fan/nf-a4x20-5v-pwm All what you post is exactly the same what i have... I don´t see a different.

Oh i found just the solution in this topic: https://unix.stackexchange.com/questions/239782/connection-problem-with-usb3-external-storage-on-linux-uas-driver-problem i need to run echo "174c:2362:u" | sudo tee /sys/module/usb_storage/parameters/quirks And after reinsert it works and i could mount the drive! And for the people who are interested. A small test on the disk: sudo hdparm -tT /dev/disk/by-label/WinToUSB /dev/disk/by-label/WinToUSB /dev/disk/by-label/WinToUSB: Timing cached reads: 2662 MB in 2.00 seconds = 1331.48 MB/sec SG_IO:

Hmm, sorry for the kick of this topic. But i trie to connect a USB 3.0 to NVME adapter on the USB 3.0 port. But just after insert it´s detected, But when i trie lsusb -v i got errors and lsusb hangs. After that the nvme disk is not detected anymore. On USB 2.0 it works ok but slow. When i connect on a USB 3.0 hub with external power the same problem happen. When the USB 3.0 lsusb -v hangs: $ sudo lsusb -v Bus 004 Device 030: ID 174c:2362 ASMedia Technology Inc. Device Descriptor: bLength 18 bDescriptorType 1 bcdUSB 3.20 bDeviceC

Oh sorry i didn´t saw your post. My fan script is now: #!/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/pwmc

Oh and btw i got contineusly the error bluetoothd[808]: a2dp-sink profile connect failed for F2:BF:67:4E:E2:A6: Protocol not available The solution therefore is to run manually bluetooth-modules-discover. pactl load-module module-bluetooth-discover

Hmm this week i thought i has restored the driver HCD file with the other mac adress. Restored again and it´s ok, But better: i have bluetooth now working i wanted. I stream from my orangepi music to a bluetooth device and it works like a charm. I have used this 2 site for reference: https://wiki.archlinux.org/index.php/Bluetooth_headset http://mygeeks014.blogspot.com/2017/05/audio-streaming-to-bluetooth-speaker.html Very very nice! Thank you all.

I has upgraded and even with a clean image Focal Desktop from here doesn´t Bluetooth works... Bleutoothctl list doesn´t show the bluetooth module also. hciconfig shows the adapter but with status down. When i try to start with hciconfig hci0 up i got the error messge: Can't init device hci0: Operation not supported (95).

hmm, i thought it was just working a few time ago. 5.7 not yet available what i see? Just waiting what i read..?

Hi all, I wanna try to use the hardware PWM on pin 7 of my orange pi one plus. Connect the fan. Toggle the SPI to enable, install wiring orangepi and all looks ok. But when in go to /sys/class/pwm i got a empty directory. I thought the should be a device pwmchip0 or something. I searched on the internet but can´t find a solution. This is what WiringOrangePi shows: Is there someone who knows what i do wrong or hwat i should do? Thank you!

i may hope the temperature reading is wrong. 83 degrees Celsius wil melt your case i think.

Is it possible to add the bluetooth and sound fix to the armbian kernel/firmware? After every kernel update sound and bluetooth stops working and it´s clear this fix works. Should be really nice!

But not less stable than a allwinner i think?

There is not much life in this Orange Pi 4 topic what i see. What Armbian build runs the best on the Orange Pi 4 / RK3399?
