[Running touchscreen 5 inch at xpt2046]

Did you check if any errors present in "dmesg" ?

[gpio PA19 hardware interrupts]

Similarly, you can also look to this python library how they handle the /dev/mem :

[H2+/H3 Initial GPIO values (at reset time)]

For GPIO, I suggest this one : https://github.com/duxingkei33/orangepi_PC_gpio_pyH3

 

IBE ? What do you means ?

 

Remote Desktop ? I'm personally only using SSH, so I can't gave instructions here, but in this forum there are plenty of post about tightvncserver ...

 

[Pine64: Pin 72/PC8 not working]

Glad that you've found out !

[H2+/H3 Initial GPIO values (at reset time)]

Where did you found OPiLite 1.2 schematic, because I think it still 1.1 version and there is no external pullups on that board.

If you are talking about internal pullups of every GPIOs, there are only turned on by software settings, so there are not present at reset, all GPIOs for almost any SoC are usually simple high impedance floating pins.

 

[Pine64: Pin 72/PC8 not working]

GPIO72 is PC8, and on my side, I don't have any error trying to export it. So, on your side, something is using it and that is why you have "resource busy".

Try to run the following command to see who is using it :

cat /sys/kernel/debug/gpio

Also, please mentioned which kernel/image are you using...

 

[orange pi zero does not start]

Any logs captured ?

Where is it jamming buring boot ?

 

[orange pi zero does not start]

Every commands added in /etc/rc.local need an ampersand '&' at the end, otherwise it will never reach the last line 'exit 0'.

 

[Pyserial not working upon reboot]

I don't see why behaviour is different.

Provide more details, show the script, and how did you place it in startup (/etc/rc.local ?)

 

[No bluetooth with AP6212a under 4.11 Mainline]

Anyway, this patch doesn't seems to take care of BT-WAKE-AP and AP-WAKE-BT.

** File not found boot/Image **

Is the symlink missing ?

[Orange Pi Zero Plus 2 H5 OTG, Bluetooth and CSI]

I've use the USB Host by simply connecting a USB connector to header pins, and it is working perfectly without any software settings, our DTS has everything needed.

 

[No bluetooth with AP6212a under 4.11 Mainline]

That is a good question ! I've never played with Bluetooth ...

Maybe we need to compare what has been done in the Legacy FEX for those GPIOA7 and GPIOA8, probably some interrupts defines.

 

[No bluetooth with AP6212a under 4.11 Mainline]

You didn't mention which board you are using ...

This is important, since some boards, such OPiWin or OPiZeroPlus, are using UART1 nor UART3.

Also, the AP6212 has BT-WAKE-AP and AP-WAKE-BT pins that maybe need to be added in DT.

Or any idea, how to compile with 512MB of RAM?

You can try adding a big swap file.

[backing up SD to filename.img]

Yes, unless you shrink the partition directly on the source media ...

 

[[SOLVED] Banana Pro No WiFi]

[backing up SD to filename.img]

Using "truncate" with the "endsect" number shown by fdisk after gparted shrinking.

Here is the sequence :

sudo modprobe loop
sudo losetup -f
sudo losetup /dev/loop0 myimage.img
sudo partprobe /dev/loop0
sudo gparted /dev/loop0
sudo losetup -d /dev/loop0
fdisk -l myimage.img
sudo truncate --size=$[(endsect+1)*512] myimage.img

 

[Orange Pi Zero wireless AP]

It is a OpenWRT distribution, and they have several images, there is one for OPiZero here : http://pulpstone.pw/sunxi/

 

[(Split from) Install to EMMC]

I've 4 OPiPC+, all installed with 4.11.5 on eMMC, and WiFi is simply working fine.

 

[Raspberry Pi]

You will need to ask that to Raspberry forum, because here, in the Armbian forum, there is NO support for Raspberries.

[UART on gpio pins Orange Pi Lite]

You can also check https://github.com/duxingkei33/orangepi_PC_gpio_pyH3

This is a python library, but inside it, you can see that it is using C for i2c_lib.

 

[Does not auto reconnect after connection lost]

What do you means by "documents" ?

[Does not auto reconnect after connection lost]

In your static IP settings, did you provided "default gateway" and "dns-nameservers" ?
