Pine A64 Configuration Tool [30/11/2016]
This tool is based on the raspi-config tool for the Raspberry Pi and it provides a straight-forward way to configure your Pine64.
Source code is available at https://github.com/Terra854/pine64-config
Prerequisites
You will need to have the xterm package installed in order to use this tool. You will also need to install newt (for openSUSE) or whiptail (for Debian/Ubuntu).
Note that for openSUSE, the tool and it's dependencies has been preloaded in the images.
Downloads
Github link
Installation/Update the tool
To install or to update this tool for your Pine64, you will need to run the following command:
Code: sudo ./install.sh [ubuntu/debian/opensuse]
This will build the scripts that is relevant to your distribution of Linux and installs it to /usr/local/sbin.
Once it is installed, you can execute it with:
Code: sudo pine64-config.sh
Enjoy!

| Active Cooling soft PWM follow-on fan motor speed controller driver |

(for schematic diagram and in-line wiring harness, see this link)
edit: I changed the default soft-pwm to GPIO23, pin(16).
The PWM (pulse width modulation) is 'soft' because it does not use a hardware oscillator. The Python codes turn the transistor on and off ( 16ms on, 4ms off) about 50 pps. The base-emitter pulls only about 2ma from the GPIO pin, while the collector current takes the main motor drive current (about 140ma for this fan).
The following two pics are my 'double' controller one half driving the PI 3B, and the other half driving the PineA64. In each case the Python code is the same; posted below:
In the pic above I also have my ada fruit gps (746) breakout mounted on the ttyS4 uart4 on the PineA64 euler bus.

| Active Cooling 5v brushless fan with Motor Speed Controller soft PWM |

The fan above is a 5v brushless 140ma fan (free standing on rubber fan mounts) capable of moving 5cfpm ; being driven by a python software PWM motor speed control driver using a PN2222 transistor to handle the current. The GPIO pin signals the transistor via 1k ohm resistor. The codes rely on the RPi.GPIO-PineA64 module from github.
I will be uploading the python codes near the bottom of this post.
The following two pics are close-in shots of the fan, and the transistor current driver:
The PN2222 transistor above can also be replaced by the 2N2222; although, the emitter collector pins are swapped-- the emitter goes to ground.
The fans ship from Jin LI , and as such take three to six weeks to ship to the U.S. Its the shipping, not Jin LI's fault. These little fans move a lot of air; however, they are also noisy. The speed control circuit quiets the fans considerably to a slight whisper, still moves the air more efficiently, and may be controlled off, or controlled by signal based on SoC temperature.

except KeyboardInterrupt:

print(" ")
print("motor controller ended by interrupt, bye!")
end()
The code may be signaled with a -SIGHUP which when received by the speed controller code will toggle the duty cycle of the soft PWM. from 80% to 100%. A second HUP will toggle the duty cycle back to 80%, or slow speed.
There will be a follow-on post with some more pics, as well a simple schematic.
edit: I changed the default soft-pwm pin to GPIO23, pin(16).

| GbE: Optionally force master mode for RTL PHY |

A while back I stumbled over this patch for u-boot https://patchwork.ozlabs.org/patch/602067/ forcing the RTL80211C/E PHY into master mode to overcome some issues when the PHY is in slave mode.
Maybe this could be a source for the random GbE problems we see here sometimes?
I was just looking at Olimex blog and read the specs for their A64 board, and one of the features reads:
Code: ...
* Ethernet Gigabit interface works just in master mode
...
I tried adding the register read-modify-write to the 3.10.x BSP driver but failed, maybe someone with better skills can have a look at it? The patch boils down to:
Code: /* RTL8211x 1000BASE-T Control Register */
#define MIIM_RTL8211x_CTRL1000T_MSCE (1 << 12);
#define MIIM_RTL8211X_CTRL1000T_MASTER (1 << 11);
...
unsigned int reg = phy_read(phydev, MDIO_DEVAD_NONE, MII_CTRL1000);
/* force manual master/slave configuration */
reg |= MIIM_RTL8211x_CTRL1000T_MSCE;
/* force master mode */
reg |= MIIM_RTL8211X_CTRL1000T_MASTER;
phy_write(phydev, MDIO_DEVAD_NONE, MII_CTRL1000, reg);
...
One read-modify-write operation....

Hi,
I have downloaded the Phoenix Card image of the rooted android on 8 GB card. First boot was OK. I configured my WiFi, tested Bluetooth. I installed YouTube.
As soon as I fired up the YouTube app my screen went black. I rebooted by powering off and then on. While booting it said optimizing android.
Now every-time after 10 seconds of boot the board powers off automatically.
What should I do.
Regards,
MB

Quote:- Execute resize_rootfs.sh script to resize the root partition in order to fully utilize the SD Card
Well I have the Debian Jessie OS up and running but I am using a 32GB SD card that only sees according to the Disk Usage Analyzer only 7.5 GB.
I tried using the terminal to execute the script but I am not sure where in the file system it is located!?
When & How to use resize_rootfs.sh?
