I really needed ADB debugging via USB(OTG). But it was hard to find the right solution.
At first I was frustrated because I did not have much information about this problem.
I have tried to solve this problem in the last few days.

Through the efforts of the past, we find one way to share.

First
Modify the USB settings in the sys_config.fex file.
The port PH09 is used as an OTG cellactor, but it does not seem to have much relation with the switcher.(Using S/W Switch)

[usbc0]
usbc0_used          = 1
usb_port_type       = 2
usb_detect_type     = 1
usb_id_gpio         = port:PH09<0><1><default><default>
usb_det_vbus_gpio   = "axp_ctrl"
usb_drv_vbus_gpio   = port:power3<1><0><default><0>
usb_host_init_state = 0
usb_regulator_io    = "nocare"
usb_wakeup_suspend  = 0
;---       USB Device
usb_luns            = 3
usb_serial_unique   = 1
usb_serial_number   = "20080411"
rndis_wceis         = 1


After setting as above, boot with new build.
A Type to A Type Prepare the USB cable and connect it to the upper port.

Then issue the following command after the su command:
cat /sys/devices/soc.0/usbc0.5/usb_device
Afterwards, you can see that MTP and ADB are connected.

To use it again as a HOST, issue the following command:
cat /sys/devices/soc.0/usbc0.5/usb_host

I tested it with Android 5.1. (PINE64 LTS Version)


I originally thought that mode conversion should be done automatically using PH09 port, but it did not.
If you have a better idea, you might as well share it.

There's been a couple of people asking about a 'how-to' for USB booting on the Rock64. 
There are now two sets of instructions on how to do it, which you can find here and here. 

[edit]The ones I wrote up on the wiki are more detailed for complete beginners while the ones on git are appropriate for those that know and understand the basics.

Hello,

Is there available the schematics of Wifi/BT module?

Thank you

Hello,

is there any available linux kernel for ROCK64 that supports mptcp (multipath-tcp) ?

My goal is to install LEDE router software (OpenWRT) for dual link bridge aggregation.

Do you know any succesfull setup of LEDE with mpctcp module on the ROCK64 platform ?


Thanks for your feedback !

hope someone can help me
I am trying to install nextcloud on my rock64. As the data directory I tried to use an external harddrive.
But there is an error when I try to use external harddrives as nextcloud data directory. When i use the
sd card as nextcloud data directory there are no probs
What I tried:
Mounting the Harddrive with fstab: UUID=a61b3225-3af0-439b-be5b-c54898b9aa46 /media/4TB           ext4    defaults        0       2
Which works for everything except nextcloud
As an alternative I tried  pmount as described on the howto for rock64. But this also doesnt work.
As OS I use debian
As nextcloud version 12.04
Any tips for nextcloud?


Greetings

I have a ROCK64 4GB setup and when I reboot I have a lot of trouble getting the unit stable.

Here are the errors that display on the screen:

core: dev_pm_opp_get_voltage: Invalid parameters
mali-utgard ff300000.gpu: Failed to get voltage for frequency 163840000: -34
devfreq ff300000.gpu: Couldn't update frequency transition information.

And then it goes into kernel panic mode.  I have to completely power down the unit,
remove the hdmi, ethernet, and keyboard cable, wait for 30 seconds and then it will boot.

I have tried a different power supply and plugging it in to a different power source.

I have 3 other similar ROCK64's working fine.

Hello everybody,

I'm trying to flash my 64GB eMMC  with the latest Android TV build from ayufan: https://github.com/ayufan-rock64/android...3-r115.zip

I've been following this guide: http://files.pine64.org/doc/rock64/guide...o_eMMC.pdf

I'm running Arch Linux. I also tried the exact same steps on a Ubuntu 17.10 machine and I got the exact same behaviour.

Here's the output of the rkinstall script:

Folks --

A happy Pinebook (and 2x Pine64) user. I've broken the AC Adapter for the Pinebook and have been unable to find a replacement online.

Is anyone able to provide a link for me (US-based).

The model is EE-0530-E.

If not where I can buy a replacement, does anyone know the Pinebook's power plug dimensions?

Thanks!

I dropped my Pinebook about 2.5 feet onto a carpeted floor.  It hit on an edge.  No apparent damage and it still works!

The space bar sometimes needs extra hitting to work.  Where on the space bar I press seems to make a difference.

I use the command line "sudo apt-get ..." instead of the Software Updater, it says "not enough disk space on /boot".

When I try to press the backspace key, I somtimes accidentally press the power key.  It then shuts down without a dialogue box.

It seems like a good buy for $99 plus $30 shipping. Its much better for general use than a pi book, which I also own.

Hello!
I am trying to use gstreamer rockchip extra plugins rgaconvert (https://github.com/rockchip-linux/gstrea...chip-extra) , but it show "no such device".
