@ReneHegewald thanks How did you activate it (change from pci to sata)?

Has anyone tried sata with mainline? Is this overlay available? https://wiki.radxa.com/Rock5/guide/sata

Were you able to stream 4k 120hz? If yes, with what bitrate and how high was the latency?

found it, had to install btrfs-progs. Sorry for the confusion.

Linux odroidn2 5.5.5-meson64 btrfs is missing in this Kernel... Are there any bugs or why is there no btrfs in 5.5 and 5.4?

I flashed the latest Armbian image on my NanoPi Neo 2 Plus's emmc. According to https://linux-sunxi.org/Linux_mainlining_effort I2S is not part of the mailinke kernel for H5. I can use I2S with Friendlyelec's images. However, I prefer Armbian. Is it somehow possible to use I2S with an Armbian image on this board?

finally had some time to flash Armbian_5.43.180423_Rock64_Debian_stretch_dev_4.16.0-rc6: root@rock64:/share# openssl speed -elapsed -evp aes-256-cbc type 16 bytes 64 bytes 256 bytes 1024 bytes 8192 bytes 16384 bytes aes-256-cbc 82888.98k 235948.63k 427434.41k 550766.25k 600880.47k 604788.05k

Thanks, that helps me a lot. Where do you set CPU and RAM clock speeds for you build process / images? Is that set in the bootloader / uboot?

Thanks Igor. I was hoping someone already did that and would share his experience in this thread.

I should have been more specific: Is AES/Crypto enabled and what are the CPU and RAM clock rates using Armbian's latest nightly Rock images? I used the search functionality and read the quoted threads weeks ago. But I also tried several of Ayufan's and also Dietpi Rock64 images and with some AES/Crypto was disabled... I did not ask if this board supports it or not.

What are the CPU and RAM clock rates? Is AES / crypto enabled?

Thanks, I was hoping for hardware enabled en/decyption. I guess I have to buy Le Potato then.

I am interested in the K2 board but I need AES support for my use case. Could you please run the following command and post the result? "openssl speed -elapsed -evp aes-256-cbc"

Thank you!
