How is the 1-wire bus enabled on a Rock64 ver 2 with Armbian 20.08.17 Bionic? I have enabled the w1-gpio through armbian-config. The /sys/bus/w1/devices/ folder is empty after sudo modprobe w1-gpio and sudo modprobe w1-therm. 
 
Below is what is in the armbianEnv.txt file in the /boot directory.
verbosity=1
bootlogo=false
overlay_prefix=rockchip
rootdev=UUID=cbeeff94-c38d-4a79-b10a-3854a2470be4
rootfstype=ext4
usbstoragequirks=0x2537:0x1066:u,0x2537:0x1068:u
overlays=i2c7 spi-spidev w1-gpio
 
In the /boot/dtb/rockchip/overlay/ directory there is a file rockchip-w1-gpio.dtbo.
 
I have connected the VCC pin of the DS18B20 to 3v3 physical pin 1, ground of the DS18B20 to physical pin 9, data of the DS18B20 to physical 7.
The DS18B20 address and w1_bus_master1 do not appear in the /sys/bus/w1/devices/ folder.
 
What more is required to see the DS18B20 and take readings?
 
I have already connected an 18x2 LCD to i2c and am writing information to the LCD using python.
 
Thank you for the help.

Hey Guys!

Curious if anyone else has run into this. I received one of the Manjaro CE devices a couple weeks ago now and was one in the batch that happened to come with PMOS instead of Manjaro. 

I figured flashing would be simple, so decided to give PMOS a go for a bit before flashing (since it was there and I was also interested in it). However, after a few minutes of use, I ran into an issue where after entering the PIN on the lock screen, the desktop would show for just a second, then fade to a blank black screen.

I had already setup SSH and connected to Wifi before this problem started, so I was able to verify that the device was on and response with a remote connection to it. I rebooted a couple of times and still ran into the same issue from this point forward. 

I took this as an opportunity to flash with Manjaro CE and sure enough, I have the same issue. The only difference is that the blank screen on Manjaro is gray instead of black, so it's easier to tell that it really is still on. 

In both cases, the screen fades to the blank state, so I can see the desktop for just a second before it becomes blank. 

Anyone else seen this issue and solved it?

I'll keep poking at it and update here if I figure it out or find another thread on it (I ran a quick search and didn't find anything just yet).

When I got my pbp back in August/Sept I tried the newest version of ayufan's chromeos build and poked around a little before moving on to other distros.  I recently had a reason to go back to chromeos and cannot login.  I have reflashed the sd card with 3 different version of chromeos and get messages about my account not being verified, but I can still sogn in as a guest and access gmail and such from inside the guest browser.

Doing web searches on this this problem reveals that it isnt exactly uncommon, but that a "powerwash" is the key to resetting a regular chromebook and fixing the issue.  The key combos for powerwashing do not work however (prompts restart but never prompts to begin powerwash), and there really shouldnt be a need to powerwash a freshly installed sd card anyway right?   

My best guess is that there is some sort of leftovers from the first chromeos sdcard that I poked around with somewhere/somehow on the actual pbp and google isnt allowing sign-in.  I am using a different sd card, and have tried the same on also, and as I said befiore I have tried 3 different of ayufan's build.  None will let me sign in as anything other than guest.  Any thoughts and help are appreciated.  Ty

Hello everybody,

I have got a question about the move of Ubuntu Touch to Ubuntu 20.04.

If I understand this topic correctly, Ubuntu Touch is currently bases on Ubuntu 16.04 and shall be moved to Ubuntu 20.04 in order to have newer packages.

But what will that exactly mean for Ubuntu touch? Will we then be able to install normal Linux apps and run them on Ubuntu Touch without Libertine?

I think that the ability of running normal Linux apps in Ubuntu Touch would really be a thing. Is that gonna come?

Best,
Thomas

My Manjaro CE Pinephone arrived and I have to say given all the discussion about people finding many of the features unreliable (which I was OK with as it's an open platform that's under development by the community), I am astonished and delighted how good it is!  

Thank you and well done to Pine64 and to everyone in the community for making a great Linux phone.

It arrived when DHL said it would. It was well-packaged and presented. I was impressed with the setup process which even included privacy-focused details like a link to UBlock Origin from the Firefox default home page.

Wifi, web surfing, the camera, all worked great. I put in my SIM card and tried out a couple of calls, expecting them to barely work but was pleasantly surprised to get crystal clear audio (the person's voice sounds altered, like talking to a different person, but it was clear and easy to understand). When I first called my partner I feared it wasn't working right because it sounded stuttery but it turned out that was just because I had it on Speaker and she was reacting to hearing her own voice! Obviously some kind of echo-cancellation algorithm could help there.

The only very minor issues I've had so far are the rapid battery drain (which I can live with); at one point the lock screen wouldn't open when I entered the correct PIN multiple times but a reboot by holding down the power switch fixed that; and when some dialog boxes pop up on the Manjaro UI (for example from some Settings) I can't figure out how I'm supposed to close them: I've just been tapping at the bottom of the screen to show all the open windows and close the dialogs that way.

Once again, thank you Pine64, Manjaro and the rest of the community! Keep up the fantastic work!

Hi,
the mainboard arrived today and installation went smooth, except now it doesnt boot anymore :-(
I tried to boot fromm emmc and with a Jumpdrive-sdcard in the sd-slot.
I re-installed the original board (UB-Ports edition) and that still works fine.
Am i missing something or did i get a dead board?

Hi,
I can't seem to find a way  to open the pinetab: the edges seem solid.
Is there a video somewhere perhaps?

thanks

Imagine how awesome it would be if there was an add-on for the pinephone that’s was along the lines of the Razer Kishi controller for phones that would allow you to play your retro games on? Just throwing that out there

The best performing password manager ?

A few days ago it has come to our attention that a number of Manjaro CE PinePhones have shipped with postmarketOS.

Following a brief investigation, it turned out that indeed ONE out of 100 mSD cards used for testing and subsequent flashing at the factory contains the postmarketOS image.

Please accept our apologies as well as those relayed by the factory.

Thankfully, flashing an OS on the PinePhone's internal flash storage is truly trivial:

• OS flashing instructions
  
• Newest JumpDrive utility
  
• Newest Manjaro Phosh PinePhone build (at time of writing)
