Hello there are many Linux roms available for the rock64, can someone please advise me on the most stable Linux rom? Can Linux support 1080p video yet? Not just though kodi or whatever, I want to be able to use my browser and log in to steaming services like Skygo for example. Like I would on desktop, thanks.

| writing dts overlay for mcp2515 |
|

Hi there I'm trying to write a dts file to make "pican2" mcp2515 based hat working on armbian, I've wrote a dts file, compiled it, and I've put it in /boot/overlay-user/.
It's not working.
I've tried hard, but now as I'm stuck and because I'm a noob in devices-tree world I come here to ask for help, so please take a look.
here is my dts file:
Code: /dts-v1/;
/plugin/;
/ {
compatible = "rockchip,rk3328", "pine64,rock64";
fragment@0 {
target-path = "/spi@ff190000";
//target = <&spi0>;
__overlay__ {
status="okay";
spidev@0{
status = "disabled";
};
spidev@1{
status = "disabled";
};
};
};
/* the interrupt pin of the can-controller */
fragment@1 {
target-path = "/pinctrl/gpio3@ff240000";
//target = <&gpio3>;
__overlay__ {
can0_pins: can0_pins {
rockchip,pins = <0 7 0 &pcfg_pull_none>;
//phandle = <1>;
};
};
};
/* the clock/oscillator of the can-controller */
fragment@2 {
target-path = "/";
__overlay__ {
/* external oscillator of mcp2515 on SPI0.0 */
can0_osc: can0_osc {
compatible = "fixed-clock";
#clock-cells = <0>;
clock-frequency = <16000000>;
};
};
};
/* the spi config of the can-controller itself binding everything together */
fragment@3 {
target-path = "/spi@ff190000";
//target = <&spi0>;
__overlay__ {
/* needed to avoid dtc warning */
#address-cells = <1>;
#size-cells = <0>;
can0: can0@0 {
//phandle = <1>;
reg = <0>;
compatible = "microchip,mcp2515";
pinctrl-names = "default";
pinctrl-0 = <&can0_pins>;
//pinctrl-0 = "/pinctrl/gpio3@ff240000/can0_pins/";
spi-max-frequency = <10000000>;
interrupt-parent = <&gpio3>;
//interrupt-parent = "/pinctrl/gpio3@ff240000";
interrupts = <7 0x2>; // 7 2
//clocks = "/can0_osc";
clocks = <&can0_osc>;
};
};
};
};
and here is what I can read in my dmesg:

Hello all,
I got a really cool idea and I need to be tuned down a bit.
I'm making myself a bootable usb drive.
Thing is, I want to know if it is even possible to have ONE bootable usb drive for both ARM64 and x64 at once.
Maybe there is some magical™ bootloader that would work on arm as well as x64 from a single compile?
I've been googling this quite a bit, but nothing relevant has come up. This usually means that I'm acting a fool.
Putting this in the linux section, because I want to know if GRUB is even available for the Rock64.
Again, thank you for your time.

benefits of eMMC? |

I'm considering buying a RockPro64 to use as a NAS and general server, I saw that one could buy eMMC modules to use as internal memory for the board. I have a few questions here:
- What is the benefit of using eMMC rather than SD card? Speed, longer lifetime or the storage?
- How is the eMMC module attached to the board? I couldn't identify an obvious slot or similar connection.
- What is the purpose of the USB adapter, is it to "burn" the OS image to the eMMC or do you need it to attach the eMMC to the board?

| HDMI display + resistive touch layer. |

Hey everyone.
I am planning on building a (edited "table PC" using the Rock64 (don't have it yet). I have an old monitor from my old laptop for which I bought a controller board and would like to use it somehow. But I would also like to add a touch layer to the LCD. More precisely this resistive touch layer.
However, I have no idea, if or how is that supported on Rock64, so if anyone can give me an advice if it will even work, or how to make it work, I would greatly appreciate it.
Thanks, everyone.

| Change Mac address on Linux |

I recently received my ROCK64 and installed various flavours of Linux on it. One thing I cannot seem to figure out is how to change the MAC address of ETH0.
On Armbian Bionic I tried putting it in /boot/armbianEnv.txt as etheraddr= or mac_addr=, I tried putting it in /etc/network/interfaces - all to no avail.
On Ayufan I was entirely unable to find anything to configure in this regard.
I read that a bunch of people complained about having ever changing MAC addresses on their board. I have not experienced that problem, but I want to set a specific MAC address - not fix the standard one.
Is there any way to do this? I could also recompile (part of) the DTBs if that is what it takes. I just need to know where I can find this setting (if at all). I can also install a new operating system.
I did find this; http://wiki.pine64.org/index.php/Set_Mac..._on_ROCK64 - which suggests it is possible on Android. I really do need a normal Linux though...
Anyone know how to do this?

Hi,
If you are unable to hear HDMI audio with your rockpro64 and the latest Linux release, you need to follow the instructions on setting PulseAudio default audio output
https://wiki.archlinux.org/index.php/Pul...put_source
Once you set the default to the HDMI, your audio will be routed to your HDMI monitor / TV
BTW - this also fixed the double playing speed on YouTube. Playing is at normal speed
Good luck
Yoram
