I put 10 Ohm resistor serial with battery wire and measured the current consumption with my test software in sleep or deep sleep mode.
In to the main loop I switched off the backlights, disable the LCD and put some commands to sleep the system
NRF_POWER->SYSTEMOFF = 1; 
or
sd_power_system_off();

After that I measured 63mV on resistor, that is 6.3mA this is very high!
The next step, I flashed the same software to a standalone NRF52832 chip, the current was 2uA !!
Then I put the initialized Pinetime ST7789 display to SLEEPIN mode,  with this command: lcd.sendCommand(0x10)
The result is 0.8mA = 800uA instead of 2uA.
What can I do yet?
What is the minimal current consumption with Pinetime in deep sleep?

Can anyone recommend a distro that has a working VoIP app with SIP? There is linphone for ub-ports that appears to be down ATM as is still not ported to arm64 from my understanding. Does anyone know of another?

Hi, 

i cannot register an account with an email  domain .wtf , the register form says its not a valid email
But it is

Is this restriction intentional?

hello,

I had to set up my Rock64 a few days ago because the SD card had unfortunately died.
As always, I first installed a new SD card with the image "Armbian_20.02.1_Rock64_buster_current_5.4.20". Everything great. Only my bluetooth stick does not want to run.


I don't have a desktop version, only access via SSH


The stick is recognized, as before. Here are a few system information:

Virginia Tech thinks they have solved the problem of distributing a single OS image across multiple discreet computers. Current buld are x86(amd)-64 only, but what if ... What if this could easily be loaded on SOPines and SOEdges? It might just make us cable of creating a desktop/workstation-grade PC from a RockPro64 with three or four SOPine/Edge devices in a PCIe daughter card.

Hi,

Sorry if it seems like this comes across as a wall of questions, but they all seem kind of small on their own and not worthy of their own threads.

Ive been trying to install Panfrost onto Armbian Buster (desktop, kernel version 5.4)on my rockpro64 and fell like im getting absolutly nowhere with it. I followed the installation guide (here), but dont think anything came of it (issues I had regarding screen resolution persisted). First question if, when checking if CONFIG_DRM_PANFROST is enabled (grep PANFROST /boot/config-5.4etcetc) it came up with CONFIG_DRM_PANFROST=m. I take it this means it isnt enabled, and to enable it the kernel would need to be recompiled?

The next question is does Panfrost usually require any more setting up after the steps listed in the guide above? Asking since as far as I can tell Xorg still loads the modesetting drivers instead of mesa/panfrost (looking in /var/log/Xorg.0.log shows Xorg still loading fbdev_drv.so and modesetting_drv.so, with no mention of other graphics drivers). Even if CONFIG_DRM_PANFROST=m is incorrect (I suspect it is), ninja seemed to exit without any errors, which leads me to believe that it installed correctly (to some extent at least)

Final question - is it still even necessary to install panfrost using the guide above? Main reason I ask this is it seems quite old, with panfrost having been around for a few years now and seeming to work reasonably well have any of the rk3399 distros added it to their repos, or is that still quite far down the line/am i just misunderstanding how panfrost works?

Any help is greatly appreciated!

Sorry if this a dupe of prior questions about hypervisor implementations on Pine hardware.

Has anyone out there installed the Xen hypervisor on the Pinebook Pro then reinstalled Manjaro?

I don't want to reinvent the wheel.  I'd like to be able to run customized images of Raspbian in a virtualizer not an emulator.

Just found be Pinebook Pro and it looks quite promising.  Also am looking to replace Presario running Linux as my alternate to Windoz platform for the household, also, again, the Pinebook Pro looks like a no-brainer.

Hello Piners

Which bootloader shipped with the "january" dispatch of PBP, with default debian mate?  Extlinux? 

When I looked in /boot, I saw directory called extlinux, and in that was file "extlinux.conf," whose contents reminded me of uefi on x64, because of the append line.

I noticed it had entries for PINEBOOKPRO, and PINEBOOKPRO-prev-kernel.

Without any docs, I intuitively created another entry for PINEBOOKPRO-SLARM64, and changed the append line to root=/dev/mmcblk0p2, as well as changed the default to my new entry, and adding slarm64 to the menu line.

I was kind of amazed that it worked, and booted slarm64 (unofficial slackware for arm) from the microsd (still using the kernel image and dtb that shipped).


I see lots of posts and instructions about flashing u-boot to SPI, but that doesn't seem necessary to boot from microsd.

On x64, most hardware have some kind of key that you can hold down during boot to bring up a boot menu.

Does this extlinux bootloader have a way to bring up its menu like that?  It has an entry  in extlinux.conf called menu.  It looked like this:

Hey,

Judging by current progress (not all merged by the time I write this) I think that by the end of the summer we'll have a fully functional Ubuntu Touch system.

At any rate, this will be my daily driver and there is one thing I'd like to see on UT - a GBA emulator. Someone keen to take this on and submit to the OpenStore?

[edit] As an enticement, there's a reward for the person who makes this happen.
[edit 2] Since you can use webapps in UT, I think that using this javascript emulator would work well,

Hey guys, anyone tried using the Dolphin Wii/Gamecube emulator?

I have tried it on Android, Manjaro and Kali so far on the pinebook pro.  Android was not worth the time to use at all, too slow on this build.  I remember Manjaro also being slow too.  I tested it out with kali today and i was getting at least up to 30 fps (mario kart double dash), but it would drop to 7fps a lot of times.

i tried WADs (Final Fantasy 2 & 3) --> didn't work, very slow
Mario Kart Wii, was very slow
Mario Kart double dash, was playable
Star Wars force unleashed 1 & 2, also sluggish

This is an ok start, I would like to see this emulator get some more love on SBCs and Arm64 based hardware.
