Does pinephone support composite output?

We're about to turn PinePhone on Apache NuttX Real-Time Operating System into a Feature Phone... But to talk to PinePhone's LTE Modem, we need a NuttX Driver for Allwinner A64 USB Controller.

In this article we’ll dive into PinePhone’s USB Controller…

1. Why PinePhone needs USB for Voice Calls and SMS

2. What’s inside PinePhone’s Allwinner A64 USB Controller

3. Which is actually a Mentor Graphics Inventra USB Controller

4. We’ll study the FreeBSD Driver for the USB Controller

5. And how we might port the USB Driver to NuttX RTOS

6. By comparing with the STM32 USB Driver for NuttX


NuttX RTOS for PinePhone: Exploring USB

I've been distro-hopping on the PP and find that most current versions--Manjaro, PostMarketOS flavors--don't recognize the kb OOTB.

Is there a current OS that does play nice with the kb, and if not, could somebody point me to an earlier version of an OS that does work with the kb, and I'll just pass on the updates until further notice?

Many thanks.

I have a pinephone pro explorer edition which just simply refuses to boot into recovery mode. I am trying to put arch-arm onto it, I've flashed the microSD, put it in the phone, but I cannot get the phone to boot from it or boot into recovery mode. I have tried every method I could find. Every time it either boots into the current os, or the led flashes red a bunch of times and the phone vibrates a lot before just turning off again. I have tried multiple SD cards and multiple flashes. No clue where to go from here it's been driving me nuts all week.

I have a 14" PBP that I had been using normally in North America. Since I moved to Europe I have not been able to boot it. When I connect the barrel charger the light stays orange/red. Sometimes I get the manjaro logo for a few seconds and then the screen goes black. I am wondering if there could be a voltage issue or if I should try to switch off the eMMC (as suggested here: https://forum.pine64.org/showthread.php?tid=10093).

Thanks!

I'm just going to do a fresh reinstall but wanted to post in case this is a common issue or someone else has it.

My battery died so I tried to charge it back and when I booted, the GUI wouldn't boot up but it booted to a shell with a "PostMarketOS loading" screen. 

Some commands work after logging in but not all, is there a command to launch the GUI?

edit: possible help here but I didn't find anything to make use of - https://wiki.postmarketos.org/wiki/Troubleshooting:boot

have a Rockpro64 with OpenWrt

I try to use the output jack, but I have no sound output detected

I'm used to seeing an update around the 15th of each month on the Pine64 blog. Are those not happening anymore?
Are the updates somewhere else?

Finally got Android 9 running on RockPro64.
It was a lengthy process as the dd commands given in the pine forums repeatedly did not work.
I managed to get an install of Android 9 http://files.pine64.org/os/ROCKPro64/and...8GB.img.gz
using Balena Etcher to write the file to SD.

I also erased the SPI Flash with the "erase" file at https://github.com/ayufan-rock64/linux-u...f9f19116f1

Installing Armbian was much easier, using the "UBoot" at above address.

What is the best distro to run SXMO on Pipephone Pro?
