  touch screen API resources?
Posted by: Rich_Morin - 08-05-2020, 09:22 AM - Forum: PostmarketOS on PinePhone - No Replies

The PinePhone touch screen controller GT917S datasheet contains a lot of useful-looking information, but (of course) it says nothing about the API(s) that can be used to access the controller. I'm interested in supporting braille input on a PinePhone, probably on Mobian and/or pmOS. Can anyone point me to some relevant resources?


  Bricked phone after u-boot update
Posted by: DarkManiels - 08-04-2020, 08:00 PM - Forum: Mobian on PinePhone - Replies (6)

Hi there - I'm hoping someone can help me figure out how to fix my Mobian installation. I've got it installed on the eMMC, with a 128Gb SD card for storage of music and such, and it's been working great since I got the phone several weeks ago. Today I did a couple of apt update & upgrades. On the second update it told me that u-boot-sunxi and u-boot-tools were among the packages to be updated. I ran sudo apt upgrade as usual to upgrade the other packages in the list, but then following the directions on the Mobian wiki Tweaks page I also ran

Code:
sudo u-boot-install-pinephone

to actually upgrade u-boot. The output in the terminal was exactly the same as the last bit of output from my regular sudo apt upgrade, so I don't know if this actually did anything different or not.

I then tried to reboot the phone, since I figured this would be good after updating the bootloader, and after it shut down nothing happened. Now whether I push the power button briefly or for 5 seconds or so I can't get the phone to turn on - the screen remains blank and off. No green LED, nothing. I swapped out my SD card for a Jumpdrive card and am able to get in and see my filesystem just fine. But when I remove the Jumpdrive SD again I still can't boot into Mobian.

Any thoughts on how to be able to boot into Mobian again would be much appreciated. I'm assuming with Jumpdrive I can do something to fix it, but am not familiar enough with the boot file system to know what files to replace or commands to run. Thanks!


  PinePhone CAD Models for Design Improvements
Posted by: jdmark - 08-04-2020, 07:37 PM - Forum: PinePhone Accessories - Replies (4)

Does anyone have a link to the PinePhone CAD models? I might have a design improvement or two that I would like to implement using CAD and either make a custom part or contribute them directly to the Pine64 PinePhone project. If someone would care to share them I would appreciate it, thank you.


  Nodes not booting
Posted by: User 18962 - 08-04-2020, 06:50 PM - Forum: Clusterboard - Replies (23)

Im running into an issue where i added a 128gb EMMC to my clusterboard and now my nodes wont boot.

removing the emmc makes no change and only having one in doesnt matter either, they boot in the baseboard.

is there a way to plug something into the USB port on the cluster board to find out what its complaining about? 

any help would be much appreciated.


  Annoying phosh
Posted by: Zweitaktmotor - 08-04-2020, 05:44 PM - Forum: PinePhone Software - Replies (1)

The most annoying feature of phosh is the fact that running applications take up more than half of the home screen, leaving very little space for the rest of the icons at the bottom. - Can't this be changed?


  Pine64 UART4 RTS
Posted by: jeanmarc-bonzom - 08-04-2020, 03:20 PM - Forum: General - No Replies

Hi,

I'm using a Pine64 with Raspbian and everything is fine.
My project uses the UART4 and as I have a device with very specific and short timing I developped a Linux Line Discipline for that.

Everything is still Ok, but I'm facing an issue (maybe a newbie issue...) I cannot get RTS line (pin18 / PD4) controlled, neither from C from inside ,my line disciple neither from python with PySerial.

BTW, to veryfy I've connected a bitscope to lines Euler2 pins 18-19-21 and I see the signal on pins 19 & 21 (Tx & RX), but desperately nothing on pin 18 (RTS).

Are the RTS/CTS lines activated on the device or should I add an overlay for that? Or at least where to check?
Any clue?


  Camera
Posted by: GloriousCoffee - 08-04-2020, 01:42 PM - Forum: UBPorts on PinePhone - Replies (3)

Hi

Launching the camera app on Ubuntu touch, but the camera feed is black. Is this to be expected at this point in time? Could not get any picture from it on PostmarketOS with Cheese either.


  Ubuntu touch, volume
Posted by: GloriousCoffee - 08-04-2020, 10:31 AM - Forum: PinePhone Software - Replies (3)

Hi

Is it not possible yet to change the volume of a call in Ubuntu touch? I can not find any settings for this, and the up/down buttons on the side only seems to affect the speaker/s but not in call.


  Any chance that we get WiFi texting/calling on UT?
Posted by: ragreenburg - 08-04-2020, 09:13 AM - Forum: UBPorts on PinePhone - No Replies

Haven't seen any discussion on this (if there has been, I apologize) and was just curious if maybe this was a possibility.
