Hi,

I have a Pine64-LTS with 16GB eMMC, running the Stretch minimal Sopine kernel by Ayufan (https://github.com/ayufan-pine64/linux-build/releases).

I am trying to install a 3G hat in the Pi bus, and need to enable some GPIO pins. I have followed the tutorial that pfeerick wrote in this forum (https://forum.pine64.org/showthread.php?tid=2088).



I am working with GPIOS 6 (230 in Pine) and 21 (75 in Pine). Just need to put them as output with the 1 value. But a few seconds or minutes (less than 10 minutes) afters setting these GPIOS, I lost the capacity to read or write to the disk (the emmc). It happens even when there is not anything connected to the Pi bus.
These are the errors that I can see in the syslog:

Nov 30 20:02:42 sopine kernel: [169456.474748] sunxi-mmc 1c11000.sdmmc: smc 0 p2 err, cmd 18, RD SBE !!

Nov 30 20:02:42 sopine kernel: [169456.515171] end_request: I/O error, dev mmcblk0, sector 1116632


I have tried several combinations (with or without ataching a hat), but it always happens after touching these GPIOs.

Have anyone see before a problem like this?

Thanks!

I have an odd problem. The IDE by Arduino has transparent fonts. It's usable only if the window below is dark, however the menus are unreadable, as they appear over the IDE itself.

I found out that disabling the window compositor solves this issue (alt+shift+f12) anyway it gives others, like an annoying flickering of the panel that sometimes disappears for a while.
I tried disabling the graphical eye candies, but with no luck. Only disabling the screen compositor works.


I'm running the stock Linux version.

Does anybody know whether there's a 14 inch 1080p Pinebook coming?

I'm using the PineA64 (from the original Kickstarter). 

I live in Germany. 

I'd like to get a battery pack for it, but unfortunately Pine64's store will no longer ship the battery overseas. My goal is to find an equivalent battery here in Germany, preferably on Amazon.de.

I've looked up the part number of the battery here, found the specification sheet here, as well as looked at the available documents here in the Wiki. It appears to be a JST three pin connector - with red as power, black as neg/ground, and yellow as ??? (I have no idea) - but I can't confirm. [/url]

Can someone confirm both the connector type and the pinout for me - or perhaps just recommend a compatible battery model sold here in Germany (easiest way to find one might be to go to [url=https://www.amazon.de/]Amazon.de directly?). 

Thanks!

Is there a desktop version for the Debian Stretch? I see there is a Minimal version to download here: http://wiki.pine64.org/index.php/ROCKPro...5B0.7.9.5D.
but I'm looking for a version with a GUI...

For some reason, my 1080p Pinebook has a stable connection only with my home network. I run Armbian Mainline (but I've seen similar behavior with KDE Neon, too). When I connect to other networks, such as my work Wi-Fi network - connection randomly goes down and won't connect after that at all. The only solution in this case for me is to do

# rmmod 8723cs
# modprobe 8723cs

But this works only until first connection loss, because it would eventually stop reconnecting again and module would have to be reloaded again. This is most likely a driver issue. Has anyone encountered such behavior?

hello,
it's possible use the cpu cooler with DAC Audio on Rock64 ?

The TOSLINK out, work with OpenMediaVault 4 ?


Thanks in advance

Hello,

currently i try a usb3 camera in order to evaluate the performances of such camera on the Rock64. This camera is able to supply 240 frame/sec with a resolution of 1448x1086 and it works fine on a pc; the required bandwidth for such data flow (1448x1086x240x8bits = ~2.9 Gbits/sec) is largely supported by the USB3 which allows up to ~5GBits/sec.
On the Rock64 i can get only 200 frame/sec ( ~2.4 Gbits/sec / ~300 Mo/sec) which is sufficient for my application , but which is also lower than what the camera can do. As i read on this forum that some users encountered problems with the "speed"  of usb3 storage devices, i wonder what is at the origine of this low usb3 bandwidth of the rock64: the soc (rk3328), DRAM, the linux version i used (bionic), ...?

Regards

I have recently purchased Pina64+ board and tested with Armbain server image based on kernel 3.10. I need to connect audio codec
in the I2S pin of Euler bus.  I would like to know what all changes in the dtb file or even in the kernel need to be made in order to work
with my audio codec which works in master mode. Basically A64+ should work in slave mode.

Any help will be highly appreciated.

I found two Pine A64 2GB laying around few days ago and decided it's time to make them useful.
So I installed armbian xenial on 32GB samsung evo card on one of them and then installed latest version of mongodb community version on it.
I can't run mongo.
I can't open log file to see what's wrong.
System hangs every little while.
I'm very disappointed and don't know what to do.

Boy, this board sucks.
