LCD not functioning with A64-LTS/SOPINE |
Posted by: icullumber - 03-14-2018, 04:46 PM - Forum: Android on PINE A64-LTS / SOPINE
- Replies (14)

I have a SOPINE module on a Baseboard Model A Rev. B that I am trying to get working with a LCD display. All components have been purchased from PINE64's store, including power supply.
Using Android 5.1.1 I am able to flash an image to a SD card and run it with HDMI output. The LCD stays blank. The backlight doesn't even come on.
Using Android 6.0.1, which states that it supports dual display, I am able to run the board just fine with HDMI output. However, as soon as I plug in the LCD the system won't boot. The power light comes on for a couple of seconds and then it goes off. This can be repeated by asserting the power button. After asserting the power button, the power light comes on for a couple seconds and then shuts off. It would seem to me that something is forcing the SOPINE to power down when it tries to power the LCD and I'm not convinced that it is hardware related.
My initial thought would be that the LCD is bad. This theory seems to be disproved when Android 7.1 is loaded on the SD card.
Using the Android 7.1 image for A64-LTS/SOPINE everything, again, works just fine with the HDMI output. The LCD screen, however, has its backlight turned on during initial bootup and there are a couple of flickers of the screen, but as soon as Android starts the LCD screen is turned off. I have tried manipulating the uEnv.txt file, but to no avail.
Does anyone else here have experience with a similar setup that you were able to get working? If so, what image did you use?
I'm not yet convinced that there is something wrong with the LCD, but I am open to the possibility that there is. The issue that baffles me the most is why it just shuts off when using Android 6.0.1.
If anyone has any insights into why it is behaving in any of the ways listed above I would greatly appreciate hearing them. Thanks.

eMMC module as storage for Debian/Android |
Posted by: le_moose1 - 03-14-2018, 09:24 AM - Forum: Debian

I had a number of unsuccessful attempts to load Android onto the eMMC card.
When I boot into Debian, the card shows up as two drives as "system" and "Volumn"
What my intention is to use the card to store media for KODI use on either Debian or Android.
Any ideas on how to format it in place running Debian? I'd rather not get an adapter.
Many thanks in advance

Clusterboard Feature request topic |

- Replies (4)

I couldn't find one anywhere else on this forum; maybe it's a good idea to have a feature request topic since I believe it is a prototype and thus still in development?
Things I'd love to see changed:
- A second ethernet switch, to serve as an ethernet backbone between the SOPine modules, for inter-module traffic (cluster/config sync/HA traffic, front/backend separation, etc).
- A physical connection to that backbone switch so you could connect multiple clusterboards and have modules from different boards directly interact without using up bandwidth on the main switch
- A different placement of the pin headers for the modules, these aren't accessible when a heatsink is applied.
- A step-up converter to 12V and Pin header for a cooling fan (so you can simply use one powersupply and don't need a seperate one for the fan).
- Some form of individual remote control; remote power/reset functions, serial over ethernet type functionality
If this kind of feedback is unwanted, go ahead and close the topic

SOPine modules stay off at reboot? |
Posted by: PeterKeuning - 03-14-2018, 05:06 AM - Forum: Clusterboard

Hi,
I've received my clusterboard with a total of 4 SOPine modules, which all seem to work just fine.
However, on rebooting a module from the Armbian CLI (either by using 'reboot now' or 'telinit 6'), the module power off and just won't turn on again until I either hit the reset button on the board or power down the PSU entirely. They just remain in a powered off state (with the LED next to the USB port very dimly lit).
I'm using the server version of Armbian 5.38 / Ubuntu xential 3.10.107.
What am I missing here? Why aren't the modules powering on?
Peter

Latest Rock64 board hardware revision |

Can anybody recently bought Rock64 share the hardware revision that is printed on the board ?
I bought one on Taobao (cannot order in China), and the PCB is printed with the following info:
ROCK64_V2.0
2017-0713
I guess it probably is not the latest build.
Also, anyone knows the hardware revision change history, or where I could find that information ?

Some questions about r64 and ayufan android tv |

I ordered a r64 2gb today with 16gb Emmc and wifi antenna. Can't wait to get my hands on it.
I'm planning to run android tv on it, does it support hdmi-cec, so I can use the remote from my TV?
And will the wifi antenna and Bluetooth stick work right out of the box or did I need to configure them?
And there are 3 images of android tv from ayufan(raw, update and the normal one). Which one do I need to flash it on Emmc (I ordered Emmc to USB connector for easy flashing )
Thanks in advantage

[feature request] please enable memtest in the kernel |

I would love to see how a kernel with memtest behaves on my board with lots of bad RAM, unfortunately passing memtest as kernel parameter does not have any effect, so I guess its not enabled in this kernel. Unfortunately I have no idea how to build my own kernel.
Please add this to the kernel configuration.
