Hello,
 
    I want to interface rockpro64 with external sensors with I2C, UART, SPI   and blinking led using GPIO pins, is there any liberay or example programs. I have installed Armbian_20.05.4 OS.

Regards,
Madhu K S

I read somewhere here that someone had ordered and received their Pinebook Pro with a larger eMMC.  Is it possible to do this?  I would like the 128Gb eMMC, but can't justify buying one separate and then ending up with a spare 64Gb one that I don't need.

Hi folks,

It is quite common for Android phones to share mobile broadband connection via wifi/bluetooth/usb to you can browse internet in other devices that doesn't have mobile broadband capabilities (aka tethering).

Has anyone tried to make tethering work with the pinephone? I guess the most difficult part would be to set the wireless interface in 'master' mode to be able to run hostapd or something similar... (IDK if the chipset supports master mode)

Thoughts?

Thanks!

# I am working on a new installation of Armbian for Rock64, and have been having an inordinate amount of trouble
# I was working and struggling mightily with getting full disk-encryption on the device.
# I now have another, more low-level problem: connecting to the internet.
# I don't know what is causing it, but suspect a random number generator required for ethernet may have stopped functioning.

# I verified the image I am using is the same one available at this time from:
$ wget https://dl.armbian.com/rock64/Buster_current
$ if [[ `md5sum file_i_used.img | cut -d ' ' -f1` == `md5sum Armbian_20.05.2_Rock64_buster_current_5.4.43.img | cut -d ' ' -f1` ]]; then
    echo MATCH;
    else echo DIFFERENT;

# I discovered the internet connection problem quickly upon trying:
$ sudo apt install (package names)
| -> Could not resolve 'deb.debian.org'
| -> (With lots of other probably-irrelevant information)

# My first thought is to test network connections with ping:

| -> connect: Network is unreachable
$ ping 192.168.1.254

# systemctl --state=failed reveals that haveged.service failed.

# My next thought is to check the interfaces
# eth0 appears to be up:
$ sudo ifconfig
| -> eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500

# Why not try to stop and restart it?
$ sudo ifdown eth0
| -> ifdown: unknown interface eth0
# It's still there:
$ sudo ifconfig
| -> (eth0 still listed)

# Can I stop and restart the loopback interface?
# I can:
$ sudo ifdown lo
| -> echo $? -> 0
$ sudo ifconfig
| -> (lo not listed)
$ sudo ifup lo
| -> echo $? -> 0
$ sudo ifconfig
| -> (lo listed)

# I add the following lines to both the /etc/network/interfaces and /etc/network/interfaces.default files,
# but nothing changed. This appears to be a pretty basic configuration So I don't know why:
"auto eth0"
"  allow-hotplug eth0"
"  iface eth0 inet dhcp"

# Something else new that caught my eye is that the board's red LED is blinking in a rhythm suggestive of the human heartbeat.
# I found this page regarding the LED, but that's all, and there's not much indication of what they really mean:
# https://forum.pine64.org/showthread.php?tid=5847

# I definitely don't have any heartbeat sensors attached, and I tried writing the same image to an SD card with the same results:
$ cat /sys/devices/platform/leds/leds/{standby,power}/trigger | egrep -o '\[\w+?\]'
| -> [heartbeat]
| -> [mmc0]

# The led indicating an ethernet cable is blinking normally
# I poked around using commands like the following to try and find ethernet-related LEDs but found nothing suggestive of ethernet:
$ find /sys/devices/platform/leds -type f
| -> nothing interesting
$ find /sys/firmware/devicetree/base/leds -type f
| -> nothing interesting

# Upon searching duckduckgo some more I find little that appears relevant
# This was one of the few things that looked promising:
# https://raspberrypi.stackexchange.com/qu...face#14107

# So I check the routing table:
$ sudo route -n
| -> Destination    Gateway    Genmask    Flags Metric Ref      Use Iface
| (None listed)

# Attempt to add default gateway manually:
$ sudo route add default gw 192.168.1.254
| -> SIOCADDRT: Network is unreachable

# what would raise error exit code 7?
$ echo $?
| -> 7

# Check routing table again -- nothing changed, still empty:
$ sudo route -n
| -> Destination    Gateway    Genmask    Flags Metric Ref      Use Iface
| (None listed)

===================================================================================================

I will post more updates as I continue to work on this problem.
Can anyone help?

What was the reason behind the increase in PineTab cost (Initially the standalone tablet was supposed to be $79.00 + $20 for the optional keyboard)?  or is this just a temporary increase for the Early Adopter shipment?

Also in the future could there be a lower cost PineTab (with NO battery) for an AC adapter powered tablet/kiosk application?  Would this also help lower cost of shipping and be orderable/shippable with other items?

Even though I received my PinePhone Braveheart months ago (albeit not using it as my daily driver), I just noticed that there are actually 2 screen protectors layered. The top one should be removed because it gets scratched very fast. Hence I thought the screen protector was of poor quality where as it does not seem to be actually. This info could be made clearer somewhere (in the box and/or in the store ?).

Just received my PINEPHONE - “Community Edition: UBports" Limited Edition Linux SmartPhone today and have a few questions.

What is the procedure to update the operating system? (see below)

I removed the plastic that covers the connections of the battery during shipment then booted up the phone.

I played around with the phone got the WiFi setup and connected.

Noticed the camera does not work just starts to a black screen, is there a fix for this, my first thought was to update the phone

The app store thing also never loads.


Thanks in advance.

Since I have a Braveheart v1.1 phone and can't used it due to known issues of excessive power drain (even when turned off), I created an Electron application using React to display a clock and my electrical provider's rate.  The app checks the electrical provider's rate every 5 minutes and when the cents/kilowatt hr is over 6.0, the screen turns red from green.

I will most likely ship the phone off to my father when I can get the USB CC and power drain components fixed.  This depends on Pine hooking up a person to solder/desolder the respective fixes.  Until then, it has become a mini screen on my entertainment center.

ps. don't judge my mess

Hello,

today I got my Pinephone64. Unfortunately, the SD card cannot be used. It is recognized but is not automatically mounted. The camera is also unusable. I think this is due to the incorrectly integrated SD card. The SD card is displayed under External Drives. I can only format it or remove it safely. An error appears during formatting: "Format Error. There was an error when formatting the device". I can also mount the SD card in the terminal and access the files. Only it is not automatically integrated. I could solve this problem by integrating them into the terminal. However, the camera remains unusable. The trigger button is greyed out.
Does anyone have the same experience? What can I do to make the camera usable?

The device is not really usable for me.

Thanks in advance
Pavel

I did a apt upgrade yesterday evening (about 24h ago) and saw that the only package to update the kernel was. After the update was done I rebooted the phone and it only showed a black screen.
I was running off of EMMC but I still had an older version on my SD. So I put that in, updated it and it wouldn't boot either. 

I have an unmodified Braveheart. When I try to boot the phone I see the green LED, the screen lights up black for a few seconds, it turns off, I hear the clicking from the camera and that's it. When I leave the phone running it gets pretty hot. I cannot reach it over WiFi.

Tomorrow I will try to put the latest image on the SD and see what happens then.
