Just got my 2G board with wifi module. Took me a while to get it stable (bad power cable).
I finally got remix to load and run but when I plug in external speakers and try youtube, the audio os horrible.
It's got bass, but there's a reverb/echo to it, almost no midrange, and very emphasized high end. My speakers are dual port, and are the same ones on my main pc.
They are plugged into both systems (works fine with the PC and a phone at the same time, don't say that's why it's doing it).
I use the youtube app and play a video and the audio is so bad I can't listen to it. The HDMI output *seems* ok but that's a really cheap 32" tv with cheesy speakers, so . . .
I play the very same video on my pc, it sounds great. I try the chrome browser and youtube.com, and it's "a little better" but still really bad.
it's the most recent remix OS from the pine64.com website.
I'll try linux to see if it's the OS or the board.
I already had some great help from people in irc chat....but unfurtunately the problem is still present.
1.
I received my pine64+ 2Gb together with Android SD card and power supply.
I connected to TV and there was the allwinner boot screen ...forver!
I checked SD card and re-burned android but always the same.
2.
I connected to the irc chat and
- checked power supply: I'm now using 5V/4A
- bought a serial ttl converter to debug
- checked for soldering blobs during manufacturing
- checked SD card with F3
- removed Ethernet, HDMI, keyboard and all other connections - only power and TTL are left
I tried the images:
a) Debian Mate (3.10.102 BSP 2) from https://www.pine64.pro/downloads/
b) and Ubuntu minimal image from https://www.stdin.xyz/downloads/people/l...es/ubuntu/
3.
BUT, always same problem: The pine64 crashes with "Unable to handle kernel paging request at virtual address".
Somethines during boot ...somethimes later, depending what I'm doing.
I found out that as smaller the image as longer (minutes) it takes until crash/freeze. For example, with 2b) I could login and do something but as soon as connect ethernet or load something into mem it crashes. With 2a) I'm not even possible to login - and HDMI screen is always blank.
I have attached some random serial consol logs. Please have a look to it.
I suppose that I have received a malfunction pine64 board and hopefulle pine64 will replace it and send me a new one.
Who can build the Lichee and Android source as the same feature - "Android 5.1.1 Image (HDMI Video Output) Release 20160711"?
I used these source as below. Building image was no problem. But this one is not workable. It's booting failure.
Suddenly I'm getting nothing from my Pine64. Yesterday it was happily chugging along. Today its putting out nothing but heat and red light (from the led next to the power jack). How do I verify that it's dead? What are the chances it can be replaced?
Prior to mounting the VS1838 or HX1838 IR receiver on the PineA64 SBC, it is helpful to mod the receiver; this does require some minimal (but easy) soldering skills. What is at issue is that the leads on the IR receiver are too thin to make good contact with the female header socket on the PineA64 board (found between the system LED solder pads and the audio jack just to the right of the audio jack looking at the usb port side of the board).
The pic above shows the mod; the un-modded receiver is in the plastic bag. I have cut the leads on the receiver and soldered it to three male header pins (these are designed to fit the socket on the PineA64 SoC board. The technique is straight-forward; tin the leads on both the receiver and the header pins... tack solder the receiver to one header pin (leave them on the row of pins for easier handling). Then, solder the other two leads, returning to the tack point and re-solder the first lead. Then to finish up, cut the modded IR receiver from the row of header pins.
I have placed the modded IR receiver in the PineA64 board socket in the pic above. My board has the system programmable LED soldered in place... the IR receiver plugs into the female socket with the bubble and cross facing outward : pinouts ( OUT, GND, VCC). The IR mod makes for a good electrical fit with the socket.
The pic above is the OpenHour learning remote, which works with the IR receiver provided (VS1838, HX1838). To test the remote you can watch evtest while sending control codes to the IR receiver from the OpenHour remote. Also, if you open a terminal you can see the remote signals as characters typed on the screen. The digits will be one less than displayed... the down arrow is the backspace, and several of the function buttons are alpha characters. To use the remote with gnu+linux apps it is only necessary to map the codes to functions the way you might map any media key on a standard keyboard.
edit: I will be posting the data sheet as soon as I confirm the type and model of the IR receiver as shipped.
Hi!
My pine arrived a couple days ago. I'm loving this little beast.
I have a couple trigger buttons laying around and I'd like to use one for the power off and other for the reset but I have no idea if the system is actively listening to the circuit of both these buttons.
I tried them on and nothing. Any tips?
