Hi all,

I'm very new to using Linux so please bear with me. I have stretch-minimal-rockpro64-0.7.9-1067 installed on my rockpro64. Sometimes when I uninstall packages (for example, pivpn) I am asked to reboot my system. But when I reboot and try to ssh back in, I am unable to ("Operation timed out"). I assume the system has not rebooted and I have to manually press the reset switch. However, this would be inconvenient if I wanted to access my rockpro64 from another location and did not have physical access to the box. Could anyone recommend a solution?

Thanks,

-D

My attempts (five steps) and my question follow.


1.    With the store's USB adapter, I have flashed eMMC 16GB using Etcher on a Windows 7 laptop with the image in the second link that follows.
https://etcher.io/
https://github.com/ayufan-rock64/linux-b...m64.img.xz

2.    I have put the eMMC in my Rock64.

3.    I have wired and connected the store's USB-to-serial adapter and my Rock64.
    On USB-to-serial adapter (pins at right):
Jumper is south (facing me) and set on east pair of pins, S1 and 3V3.
GND: black (goes to GND on Rock64's PI-2 bus)
RTX: brown (goes to TXD on Rock64's PI-2 bus)
TXD: white (goes to RTX on Rock64's PI-2 bus)
3V3: red (most northward cable) - NOT CONNECTED to Rock64
    On Rock64, PI-2 bus (long set of pins) is most northward; HDMI is south; GigE/USB is east.
    Bottom (southern) pins are numbered odd starting at 1 (going to 39); top (northern) pins are numbered even starting at 2 (going to 40). See,
    bottom (southern) pin (this is the leftmost one):
1  3.3V PWR - DO NOT use. See Serial Console for the Rock64 - https://forum.pine64.org/showthread.php?tid=4928 - NO EXPLANATION given for why!
    top (northern) pins:
6  GND: black (goes to GND on USB adapter)
8  TXD: brown (goes to RTX on USB adapter)
10 RTX: white (goes to TXD on USB adapter)
    Executive Summary:
USB    Rock64
GND <---> GND
Rx <---> Tx
Tx <---> Rx

4.    I have tried putty on Windows 7 (to no avail), and then minicom on Debian, and now Raspian.
    Upon plugging in USB-to-serial adapter on Debian, I saw/see a red led (and iirc, a light blue led next to it, at  least on Debian)
# dmesg | tail -n 10
    gave
# usb 6-1: ch341-uart converter now attached to ttyUSB0
    I issued
# minicom -s -D /dev/ttyUSB0 -b 1500000
    which returned (for both Debian and now Raspian)
Welcome to minicom 2.7

OPTIONS: I18n
Compiled on May  7 2017, 05:18:49.
Port /dev/ttyUSB0, 14:19:34

5. I plugged in power which lit an additional led on the Rock64. I see no change at my console (minicom).

ADDENUM: blue led is lit @RPi too; HDMI connected but monitor shows nothing.

QUESTION: What did I omit/do wrong, or what should I be doing next (or should have done before)?

Dear Manager,

I am new to Android Source code.

I have to customize Android 6.0: remove all the apks/apps and Add my own apk/app.

Please guide me the steps, how can I do it. where to make changes in source code or make files.

Regards,

Tanveer

I saw this thread:
https://core-electronics.com.au/tutorial...ry-pi.html

sudo apt-get install stress
wget https://raw.githubusercontent.com/ssvb/c...burn-a53.S
gcc -o cpuburn-a53 cpuburn-a53.S

For Raspberry PI 3,  there are 4 A53 cores only.  for RockPro64.   How to test the other A72 cores? 

Can I use cpuburn-a53 to test A72 cores?

Which port is the OTG port?

Many thanks

On my first board here and been trying to do some creative googling and getting no where.....After first install on both the Deb image and Ubuntu images(64 bit) I get several mmcblk1 errors as follows....card should be fine, works perfectly in Pi2b/3b

Well I do not know if it's already written in some post,
But I found a way to record an image on the Emmc without the adapter or the serial cable


1.- Download any minimal image for SD and record it in SD (tested with debian 0.78 minimal)
2.- You start the Rock64 with the SD card put the eMMc in place and the jumper so you do not activate it
3.- Once the minimum image has been removed, remove the jumper
4.- cd / usr / local / sbin
5.- sudo rock64_reset_emmc.sh
6.- sudo nano sd2emmc.sh
7.- curl -L https://github.com/ayufan-rock64/linux-b...m64.img.xz | unxz -c> / dev / mmcblk0
8.- You can put the image you want after download another example
curl -L https://github.com/ayufan-rock64/linux-b...m64.img.xz | unxz -c> / dev / mmcblk0
another way from a personal pc
curl -L -u Domain \ user: passwd smb: //192.168.1.9/download/xenialokrock64.img.xz | unxz -c> / dev / mmcblk0
9.- CTRL +O enter  CTRL +X
10.- sudo chmod 0754 sd2emmc.sh
11.- sudo ./sd2emmc.sh
12.- When the prompt returns to write,
sudo shutdown -h now,
13.- When this rock64 is turned off, you take the SD out of its site and reboot again without SD
14.- The image will start from the eMMC and you will have your image recorded in the SD

I hope it helps you all and if you see any error or problem you tell me

Hi

I would like to change the DSI format to RGB565.

Therefore, fix the following setting values from DTS.

[sun50i-a64-pine64-plus.dts]

I can not connect adb using USB-C or TCP.

- Using USB type C to C
    no device

- Using tcp(ping is succeed)
    adb connect 192.168.1.134
    unable to connect to 192.168.1.134:5555: Connection refused

If someone succeeds, please help me.

Thank you!

Can anyone prove or have seen evidence of;
1. well-functioning desktop can actually be installed and run on Debian?
2. that Firefox works 100% correctly on Rock64, without crashes?
3. that Firejail can run on Rock64?
