I've been trying to debug this all afternoon, for some reason there is no audio on the left channel on the headphone jack. Plugging the headphones in to my screen and listening to the audio through the hdmi output works fine. I've tried a bunch of different things, including uninstalling Pulseaudio (had to flash the OS on the SD card to restore it) that haven't worked.

Do you have any ideas? Is it possible that this is a hardware issue?

Hi

I finally managed to get SPI going, all the signals seem to be there but I see my clock signal (SPI_CLK_M2, pin23 on PI2 header) where the chip select (SPI_CSN0_M2, pin24 on PI2 header) should be and vice versa.

How to swap these around?

Also, is it possible to stop/start driving these pins at runtime? How?

Hi all.
I've been looking at buying an Odroid XU4 for having as home server (little bit of openHAB, little bit of Owncloud, maybe other stuff) and just today found the ROCK64 which seems like a very nice alternative. I got some initial questions though that I can't seem to find any obvious answers to.

I want to run this headless. I want a Debian Stretch image which least possible footprint, just so that I can SSH into it and install whatever I need. Obviously I'm going for the eMMC alternative. Is it just a question of downloading the Strech minimal image from http://wiki.pine64.org/index.php/ROCK64_...re_Release, flashing it to the card (using USB-eMMC adapter), booting up and SSH:ing in? Kinda confusing that some images on the wiki says "microSD Boot" and some says "microSD to eMMC", is there really any difference or do they all work on eMMC as well?

Also, since the form factor looks almost identical to rPI3, does it mean that it fits in rPI3 cases? Or do I need to buy the (bulky looking) "acrylic open enclosure"? The cases at c4labs.net looks really great but it's supposed to be in a closet out of way so I'd rather buy something that just cheap and effective :-)

Hi,

On 12th November I place my order and was shipped on 17th November, this is ok, but since 17th November has not arrived yet !!

Any problem with the mail packet ? 

 Order #53762
Tracking number LX595200079CN

Hi,

which HDCP version is supported by the ROCK64?

Android Project Treble simplifies building custom Android ROMs.

Providing an Android Project Treble Software Development Kit (Original vendor implementation) will make the ROCK64 much more attractive on the market!

Am new to the Rock64 board and have some questions.

I currently have 3 Raspberry Pi 3's, one running NextcloudPI, one running PiVPN/Pi-Hole, an one Running Netatalk.  I am looking to replace all three with Rock64 boards.

I just received my board, a 32GB eMMC module, and the serial console board.  I have already flashed the eMMC board with ayufan's Debian Stretch pre-release image (yes, I know it's experimental).

Now I need to boot up the board.  I plan on connecting it to a TV via the HDMI port so that I can set it up.  I am unclear in reading up on this, if that will actually work and I'll be able to see the boot up process.  Do I HAVE to use the serial board, or can I use the HDMI connection to view the boot up process?

In theory, I should be able to just boot right up into the OS as I've already written the image to the eMCC board, correct?  My plan is to hook up a USB keyboard and use the HDMI connection to a TV for the short term.  Once I'm comfortable with the OS, and have setup SSH, I'll just use that for managing the OS.  Should all that work properly?



What other OS's whould you recommend I try? Since I'm using all three Rock boards as infrastructure servers, I am just looking for a lightweight OS that I can run the service on.  Most familiar with Debian, so Stretch seemed like the best choice.

Any recommendations on cases?  This will be sitting on a shelf in my office, so I like to have a case.  With a fan if possible.  I see there are HeatSinks available so will probably go that route too.

Thank you all for any assistance.

Here is a link to the layout of the gpio pins on the rock64. If you look at the pi2 bus, pins 2 and 4 are labeled 5V input. Is this a viable option to power the board? I do not want to use the barrel jack because I am putting this board in a larger system that I already have a large 5V power supply for. If it is, do I connect the +5V to the 5V pin and the -5V to any ground pin?

I have set up extlinux.conf (on sd card) such that it will obtain the root filesystem from my USB drive. Everything works OK when I connect the drive to USB 2 port (I get the message during the boot that the drive is spinning up, the kernel waits for that and then the boot proceeds normally). This is a USB 3 drive and, of course, it would be better to connect it to the USB 3 port in rock64. When I do this, the system starts booting but then gets stuck before it says anything about waiting for the drive to spin up. I was randomly playing with the cables back and forth and somehow I managed to get it to boot once from USB 3 but I am not sure what I did exactly.

Has anyone gotten rootfs on USB 3 drive to work correctly when loading the kernel from sdcard? I know that the drive works on USB 3 port (PC) and it has its own power supply, so there should not be any power issues.

Hi, I have recently purchased a Rock64 board and I am quite newbie. 

I want to install an ESP8266 wifi module I have laying in my desk (and I tried before with an Arduino board) but I don't know where to start from.

I'm planning to use use Pi-2 BUS pins 8 and 10 -> GPIO2_A0 (TX) and GPIO2_A1 (RX).

The microchip (and also the rock board) is pretended to be powered by a computer PSU.

I think my ESP is already flashed with updated firmware so the big question is if the rock board will detect my ESP and how would I send AT commands to it.

Thanks in advance.
