[K-worker problem on A20 based boards]

Hi,

 

this fix does not work for BananaPi / BananaPi Pro.

I have blacklisted the module

 

nano /etc/modprobe.d/blacklist

blacklist sun4i_drm_hdmi

 

After that:

 

update-initramfs -u

 

But after a reboot, I still have ~10% cpu-load from a kworker process.

 

 

What I get with linux-perf-5.8 is:

 

 

Any idea?

Hi norrest,

 

I was able to fix my tutorial to work with the latest armbian sources.

The errors in your post are based on changed references in the *.dtsi file (e.g. old label: "pwm0_pins_a" new label: "pwm0_pin" ...).

 

Please try to follow the updated tutorial.

[Banana Pi Pro - 7" LCD Touch Display - How to enable?]

Hi Igor, hi all,

 

I invested some time in the problem over the weekend and was able to find a solution.

I also found a workaround for the shutdown/poweroff-issue.

 

Here is the link to the updated tutorial:

 

 

Now it would be nice to have a device tree overlay for this display.

 

@Igor, can you include the driver for the touchscreen by default (kernel config / not as module)?

 

Can anybody help to create a overlay?

[Banana Pi Pro - 7" LCD Touch Display - How to enable?]

Hello,

 

a few months ago I wrote a tutorial to enable the 7" touch display for Banan Pi and Banana Pi Pro.

Unfortunately the files (*.dts e.g. sun7i-a20-bananapro.dts) have changed and I don't know how to integrate the patches in the current armbian version.

 

Does anybody know how to do it?

 

Is there already a overlay to enable it?

 

Thanks.

[K-worker problem on A20 based boards]

Hello,

 

I know there are some threads regarding this issue, but there does not seem to be a correct solution.

 

Since kernel 4.14 (or maybe earlier), there are some Kworker processes that consume 10-25% CPU.

 

In May 2018 I once had an image built with the kernel 4.17.13. With this the problem had disappeared.
But now with the DEV-kernel 4.19.X it's back.

 

Can someone please investigate or say something about this?

Hi Igor, hi team,

 

we are using Armbian since the the first version.

We only using it with Banana Pi and Banana Pi Pro.

 

Yesterday I wanted to build a new image for our BananaPro projects, but unfortunately there is no support for Banana Pi Pro anymore. Why?

 

Is it possible to continue supporting this board?

 

What is the difference to the Banana Pi? You still support Banana Pi.

 

Thanks.

[BananaPi - Console Output when using the LVDS LCD Display]

22 hours ago, Igor said:

I think you need to remove this part.

 

Hi Igor,

 

I tried to change the value from "console=both" to "console=tty0", but when I try this with armbian-config there is no "console=" entry in /proc/cmdline anymore.

How can I remove "console=ttyS0,115200" ?

[BananaPi - Console Output when using the LVDS LCD Display]

Hi,

 

I have a BananaPi and BananaPi Pro connected to the Lemaker 7" TouchLCD.

When I boot the system, I can't see any console output. I only see a flashing cursor in the left top corner and then it starts the X-window-manager.

 

What do I have to change to see the boot messags on my LVDS LCD?

 

I have tried to change the console=both value to tty0 or tty1 via armbian-config, but this doesn't work.

 

Any ideas?

[BananaPi Pro 7" TouchLCD with Debian Buster and Mainline-Kernel 5.XX.XX]

EDIT: 04.01.2020 - Fixed patches to work with latest armbian sources. (references have changed)

 

Hi everybody,

 

Here is a tutorial to enable the Lemaker 7" Touchscreen on BananaPi Pro with Debian Buster and Mainline-Kernel 5.XX.XX.

 

Kernel: Mainline 5.4.6 / Buster
Board: BananaPi Pro

 

WebLinks:

    • https://forum.armbian.com/topic/1905-enabling-lcd-in-u-boot-kernel-472/
    • https://forum.armbian.com/topic/1849-touch-driver-banana-pi/
    • http://www.atakansarioglu.com/getting-started-bananapi-linux/
    • http://forum.lemaker.org/thread-15482-1-1.html
    • http://linux-sunxi.org/LCD

 

To make the 7"LCD and the Touchscreen working with BananaPi Pro we need to patch some files and change the kernel config to build the driver for the touchscreen.
To do this we need a working setup of the Armbian build tool chain (https://docs.armbian.com/Developer-Guide_Build-Preparation/)

 

/home/<USER>/build/cache/sources/u-boot/v201X.XX/configs/Bananapro_defconfig
/home/<USER>/build/cache/sources/u-boot/v201X.XX/arch/arm/dts/sun7i-a20-bananapro.dts
/home/<USER>/build/cache/sources/linux-mainline/linux-4.XX.y/arch/arm/boot/dts/sun7i-a20-bananapro.dts

 

1. U-Boot ( u-boot version that supports the LCD - must be compiled)

 

Start the build process with ./compile.sh CREATE_PATCHES=yes

 

When asked for:
[ warn ] Applying existing u-boot patch [ /home/[USER]/build/output/patch/u-boot-sunxi-current.patch ]
[ warn ] Make your changes in this directory: [ /home/[USER]/build/cache/sources/u-boot/v201X.XX ]
[ warn ] Press <Enter> after you are done [ waiting ]

 

a) edit /home/<USER>/build/cache/sources/u-boot/v201X.XX/configs/Bananapro_defconfig

 

add the following:

#7" LVDS LCD
CONFIG_VIDEO_LCD_MODE="x:1024,y:600,depth:24,pclk_khz:55000,le:100,ri:170,up:10,lo:15,hs:50,vs:10,sync:3,vmode:0"
CONFIG_VIDEO_LCD_PANEL_LVDS=y
CONFIG_VIDEO_LCD_POWER="PH12"
CONFIG_VIDEO_LCD_BL_EN="PH8"
CONFIG_VIDEO_LCD_BL_PWM="PB2"

 

b) edit /home/<user>/build/cache/sources/u-boot/v201X.XX/arch/arm/dts/sun7i-a20-bananapro.dts

 

 add after:

 

&i2c2 {
    ...
};

 

the following:

&i2c3 {
	status = "okay";
	pinctrl-names = "default";
	pinctrl-0 = <&i2c3_pins>;
	edt: edt-ft5x06@38 {
		compatible = "edt,edt-ft5x06", "edt,edt-ft5206";
		reg = <0x38>;
		pinctrl-names = "default";
		pinctrl-0 = <&edt_ft5x06_pins_a &edt_ft5x06_pins_b>;
		interrupt-parent = <&pio>;
		interrupts = <7 9 IRQ_TYPE_EDGE_FALLING>;
		touchscreen-size-x = <1024>;
		touchscreen-size-y = <600>;
	};
};

 

Add these two new sections to the end of the file:

&pio {
    edt_ft5x06_pins_a: ft5@0 {
        pins = "PH9";
        function = "irq";
        drive-strength = <20>;
        bias-pull-up;
    };
    edt_ft5x06_pins_b: ft5@1 {
        pins = "PH7";
        function = "gpio_out";
        drive-strength = <20>;
        bias-pull-up;
        output-high;
    };
};

&pwm {
      pinctrl-names = "default";
      pinctrl-0 = <&pwm0_pin>, <&pwm1_pin>;
      status = "okay";
};

 

Then save and press <Enter> to continue.

 

2. Kernel patches - DTB (Device Tree Blob) file that fits to your Kernel and supports pwm

 

When asked for:
[ warn ] Applying existing kernel patch [ /home/<USER>/build/output/patch/kernel-sunxi-current.patch ]
[ warn ] Make your changes in this directory: [ /home/<USER>/build/cache/sources/linux-mainline/orange-pi-5.XX ]
[ warn ] Press <Enter> after you are done [ waiting ]

 

c) edit /home/<USER>/build/cache/sources/linux-mainline/orange-pi-5.XX/arch/arm/boot/dts/sun7i-a20-bananapro.dts

 

add the same lines like section b)

 

Then save and press <Enter> to continue.

 

3. Compile Touchdriver

 

menuconfig > Device Drivers > Input Device Support > Touchscreens > EDT FocalTech FT5x06 I2C Touchscreen support

 

 

Exit and save the Kernel configuration.

 

This is the outcome. You probably have a newer version than 19.11.4:

 

Now you can flash the image to a SD-Card or you have to install the new DEBs.

 

 

dpkg -i linux-u-boot-current-bananapipro_19.11.4_armhf.deb
dpkg -i linux-dtb-current-sunxi_19.11.4_armhf.deb
dpkg -i linux-image-current-sunxi_19.11.4_armhf.deb

 

reboot

 

The result:

 

The LCD and the touchscreen are working.

 

Attention!
There is still the problem with the shutdown.
When the patches were made for the LCD, the board did not shut down completely during a shutdown (LCD still had voltage and the red LED on the board did not go out).
 

Workaround:

 

We need to disable the LCD before the shutdown is finished.

Therfore we have to create a script in the folder /lib/systemd/system-shutdown

 

e.g. (as root)

 

touch /lib/systemd/system-shutdown/lcd_off.sh

chmod +x /lib/systemd/system-shutdown/lcd_off.sh

nano /lib/systemd/system-shutdown/lcd_off.sh

 

add these lines:

 

#!/bin/bash

# LCD Power			PH12	H=8		(8-1)*32+12		= 236
# Backlight enable	PH8		H=8		(8-1)*32+8		= 232
# Backlight PWM		PB2		B=2		(2-1)*32+2		= 34

if [ ! -d "/sys/class/gpio/gpio34" ] 
then
    sudo sh -c 'echo "34" > /sys/class/gpio/export'
	sudo sh -c 'echo "out" > /sys/class/gpio/gpio34/direction'
	sudo sh -c 'echo "1" > /sys/class/gpio/gpio34/value'
fi
if [ ! -d "/sys/class/gpio/gpio232" ] 
then
    sudo sh -c 'echo "232" > /sys/class/gpio/export'
	sudo sh -c 'echo "out" > /sys/class/gpio/gpio232/direction'
	sudo sh -c 'echo "1" > /sys/class/gpio/gpio232/value'
fi
if [ ! -d "/sys/class/gpio/gpio236" ] 
then
    sudo sh -c 'echo "236" > /sys/class/gpio/export'
	sudo sh -c 'echo "out" > /sys/class/gpio/gpio236/direction'
	sudo sh -c 'echo "1" > /sys/class/gpio/gpio236/value'
fi

# LCD on/off
sudo sh -c 'echo "0" > /sys/class/gpio/gpio34/value'
sudo sh -c 'echo "0" > /sys/class/gpio/gpio232/value'
sudo sh -c 'echo "0" > /sys/class/gpio/gpio236/value'

 

The script will be executed right before the board powers off.

 

Measured power consumption:

 

PowerON (booting / lcd still off) = 0.4A - 0.5A

LCD turns on (still booting) = 0.85A - 1.05A

Boot process ended (LCD on) = 0.75A

Board on, LCD off = 0.35A - 0.45A ( -> LCD needs around 0.4A power )

shutdown -h now = 0.00A

 

4. Control the Power of the Backlight:

 

The backlight PWM is on PIN CON2 PB2.

 

Following the instructions on

http://linux-sunxi.org/GPIO#Accessing_the_GPIO_pins_through_sysfs_with_mainline_kernel

http://forum.lemaker.org/thread-10852-1-1.html

we have to export GPIO-PIN 34.

 

(position of letter in alphabet - 1) * 32 + pin number

position of letter in alphabet: B = 2
pin number: 2

 

( 2 - 1 ) * 32 + 2 = 34

 

echo 34 > /sys/class/gpio/export
echo "out" > /sys/class/gpio/gpio34/direction

 

Power on the Backlight:
echo "1" > /sys/class/gpio/gpio34/value

 

Power off the Backlight:
echo "0" > /sys/class/gpio/gpio34/value

 

Now we could use a switch connected to a GPIO-IN to control the backlight.

[Enabling LCD in u-boot Kernel 4.7.2]

Hello guys,

 

I have tried the following HowTo to get my 7 inch LCD working, but I can't find the file "sources/u-boot/v2016.09/configs/Bananapi_defconfig".

 

Can anybody help me please?

 

On 22.9.2016 at 9:00 AM, MartinKeppler said:

So, now I can tell you how to enable LCD in u-boot and DT.

 

First getting the source of armbian from https://github.com/igorpecovnik/lib

Open the file sources/u-boot/v2016.09/configs/Bananapi_defconfig and add:

CONFIG_VIDEO_LCD_MODE="x:800,y:480,depth:24,pclk_khz:30000,le:40,ri:40,up:29,lo:13,hs:48,vs:3,sync:3,vmode:0"
CONFIG_VIDEO_LCD_POWER="PH12"
CONFIG_VIDEO_LCD_BL_EN="PH8"
CONFIG_VIDEO_LCD_BL_PWM="PB2"

Now LCD is enabled in u-boot. But it will not switch on backlight, because backlight uses pwm and pwm is disabled per default in DT. So you also have to add:

&pwm {
      pinctrl-names = "default";
      pinctrl-0 = <&pwm0_pins_a>, <&pwm1_pins_a>;
      status = "okay";
};

Ready!

But be aware, LCD only turns on if there is no HDMI Monitor plugged in!!

 

Ok, hopping some one else of you can use this stuff.

 

Thanks.

[BananaPi Pro - Armbian 5.25 - 7" Touchscreen "evdev third button emulation" doesn't work anymore]

Hello everybody,

 

I was running Armbian Wheezy for a very long time. Now I switched to the latest build and I have some problems.

 

My System:

 

• BananaPi Pro
• Lemaker 7" touchscreen with ft5x_ts touch controller
• Armbian 5.25 Kernel 3.4.113
• LXDE Desktop (task-lxde-desktop)

 

Here you can download my image: www.geier-media.de/upload/armbian/armbian_jessie_5.25_3.4.113_4gb_20170319_01.zip

And here is the install text file: www.geier-media.de/upload/armbian/armbian_jessie_5.25_3.4.113_4gb_20170319_01.txt

 

Users: root (PW: ".root") / vispro (PW: ".vispro")

 

The BIN-File for the touchscreen is activated!

 

In Debian Whezzy I activated the third button emulation with the following tasks:

 

1. "touch /etc/X11/xorg.conf"
2. "nano /etc/X11/xorg.conf"

Section "InputClass"
	Identifier "Touchscreen"
	MatchProduct "ft5x_ts"
	Driver "evdev"
	Option "EmulateThirdButton" "1"
	Option "EmulateThirdButtonTimeout" "750"
	Option "EmulateThirdButtonMoveThreshold" "30"
EndSection

Unfortunately it is not working with Debian Jessie.

 

Does anybody has an idea?

 

Thanks.

the display you bought is just a normal LCD without touch. The right one is black like this: LCD with Touch or LCD with Touch
