| Help - PineBook Pro won't boot! |

Just over a week into ownership my lovely new PineBook Pro seems to have given up the ghost! When powering on, I am presented with an awful coil whine from the machine and a blank display (with backlight turned on). I've attempted disconnecting the battery and resetting using the switch on the device but to no avail! The whine seems to stop when I disconnect the display though! Any suggestions? Really disappointed that an otherwise brilliant machine seems dead to the world now!
For reference, this is the sound...

| Boot menu? |

I notice that extlinux.conf contains multiple entries, clearly organized as if I should be seeing some sort of menu at boot. Yet, I don't.
Three obvious possibilities:
- There's not actually a menu
- There's a menu, but it's not enabled
- There's a menu and it's enabled, but it goes out on the serial port
Is there a way to get a visible boot menu?
I looked into doing this with syslinux/extlinux on x86 and it seems that those methods involve adding executable things to /boot/extlinux. All the things I found were 32- or 64-bit x86, which obviously(?) won't work on the PBP.

I've had the issues with Firefox crashing on every launch (updated the OS and ran MrFixIt's update). I tried removing it and reinstalling, but there doesn't seem to be a compatible Firefox that I can find.
Is the version in the default OS a customized version? Even if not, where do I get a version I can install?

Wifi Privacy Switch without rebooting |

update 2020.06.16: some recent kernel update has changed the naming of the wifi device - now fe310000.mmc. For those who like a compact one-liner:
Code: sudo tee /sys/bus/platform/drivers/dwmmc_rockchip/{un,}bind <<< "$(basename /sys/devices/platform/fe310*)"
TL;DR: use the two commands here to restart the Wifi driver after powering the Wifi again with the Privacy Switch for Wifi (Pine + F11) :
Code: $ echo 'fe310000.dwmmc' | sudo tee /sys/bus/platform/drivers/dwmmc_rockchip/unbind
$ echo 'fe310000.dwmmc' | sudo tee /sys/bus/platform/drivers/dwmmc_rockchip/bind
The full story :
(Moving to a more general thread, because currently my reply is burried in the middle of the Manjaro discussion)
Currently, the privacy switch for Wifi cannot put back Wifi on because soldered-on-motherboard SDIO modules aren't Plug'n'Play.
Here's what you normally see if you try the usual rmmod + modprobe route:
Code: $ sudo rmmod brcmfmac brcmutil cfg80211
$ modprobe brcmfmac
$ dmesg
[ 1299.511038] usbcore: deregistering interface driver brcmfmac

[ 1313.133865] usbcore: registered new interface driver brcmfmac
There is a way though:
You can find the actual soldered device that answers on the mmcn mentioned above and unbind and re-bind it.
Code: $ ls -d /sys/devices/platform/*.dwmmc/mmc_host/mmc0
/sys/devices/platform/fe310000.dwmmc/mmc_host/mmc0
$ ls -d /sys/devices/platform/*.dwmmc/mmc_host/mmc*/mmc*/mmc*/ieee80211
/sys/devices/platform/fe310000.dwmmc/mmc_host/mmc0/mmc0:0001/mmc0:0001:2/ieee80211
$ echo 'fe310000.dwmmc' | sudo tee /sys/bus/platform/drivers/dwmmc_rockchip/unbind
$ echo 'fe310000.dwmmc' | sudo tee /sys/bus/platform/drivers/dwmmc_rockchip/bind
$ dmesg

[ 1860.053215] IPv6: ADDRCONF(NETDEV_CHANGE): wlan0: link becomes ready
Note -if I'm not mistaken : - the 'mmc0' numbering might change depending on how your OS enumerate its devices (see how /dev/mmcblk changes - on Manjaro the Wifi is on mmc0 and the internal eMMC is on mmc2, but on the factory shipped Debian - Wifi is on mmc2 and mmc0 has the external µSD)
- but fe310000.dwmmc is how this soldered MMC interface is mapped to the Rockchip and is fixed accross OSes (it is set in the .dtb)
the bind + unbind trick can also be used if the Broadcom Wifi chip has gone crazy and needs restarting.

I want to drive a 3840x2160, 4-lane eDP display. Will this work with Linux (preferably Debian)? The exact display part number is BOE TV101QUM-N00. Backlight controls don't have to work (3D printer application), but still images should.
Also, ideally I'd want the option to connect a second, low-res touchscreen. Will this work?

| PinePhone sample images? |

Hi,
could anyone in possession of a working PinePhone post some sample images from the two cameras in different light situations?
My wife wants to retire her aging Jolla phone and was a bit underwhelmed when I told her the PinePhone had only 5MP as compared to 8MP on her Jolla.
Now I wonder how the quality of the shots comes out in RL.
Thanks in advance...
