I tested this method on Orange Pi PC2 (Armbian 21.08 Focal). ~:% uname -a Linux orangepipc2 5.10.60-sunxi64 #21.08.1 SMP Wed Aug 25 18:29:57 UTC 2021 aarch64 aarch64 aarch64 GNU/Linux The instructions have a small clarification for the aarch64 architecture. The symlink must be like this to install the driver: sudo ln -s /lib/modules/$(uname -r)/build/arch/arm64 /lib/modules/$(uname -r)/build/arch/aarch64 The driver is installed and works well.

Very interesting. I also want to test it in the near future.

I bought this one a year ago, along with the board. This is a miniPCIe. Me also need an adapter to connect an NVMe SSD with an M2 key. I can't find one.

Which adapter do you use to connect the M2 for PCIE port on the orange pi 4? I can't find.

I also bought the same one, about 15 Euros. I configured the script and now it starts to rotate from +35, the rotation speed is floating. The maximum spin speed starts at +60 . This cooler is really quiet and worth it money.

@haajee , This is a problem with my cooler. It starts rotating with 3.3 V. If the tension is less, then silence. I took voltage measurements from 7 pin. The voltage on this pin is: min=1.0 V, max=2.9 V. Tell me please did you connect Noctua NF-A4x20 5V PWM directly or via MOSFET? In Noctua cooler with 4 pins or 3 pins?

I confirm. I have updated to 5.6.10. Bluetooth doesn't work now. PS: this hack helped me again. PSS: now there is no sound from the 3.5 Jack. I didn't find how to fix it. I don't want to roll back to the old kernel.

Yes, compatible. I checked that both blue ports work USB 3.0. You only need to consider that there are two types of boards: Orange Pi 4 - 1x USB3.0 HOST, 1 x USB3.0 Type-C Orange Pi 4B - 1 x USB3.0 Type-C

@haajee, I have for some reason does not work, there is no signal from the 7 pin. Kernel 5.6.3 Buster. What else do I need to do to make it work?

This is great! What version of the kernel does this script run on?

Today I enjoyed the sound from OPi4 via 3.5 Jack. The rt5651 codec transmits sound very well. Thank you again @iamdrq! The audio output was via Alsa, because Pulseaudio is not the quality I would like to get. Headphones: Sony mh755 Player: DeadBeef Format music: FLAC Sound via Bluetooth also works great!

I measured the consumption of the OP4 board: 1.Loading the operating system 2.The system is loaded, there is no application load 3. 7z benchmark. Maximum CPU load.

There is sound through the 3.5 mm jack. Good work!

No yet, I tried to compile dtb for the kernel from the repository. Can I ask you for a ready-made kernel with patches?
