From
Termux Wiki Debian, You can also install Debian with this method..
debian-on-termux
HOWTO install Debian 9 (stretch) on your Android smartphone by sp4rkie
this installs Debian Buster 10.1 ;-]....
change to home folder to install...
Code:
cd ~/
apt update
apt install wget
hash -r
wget https://raw.githubusercontent.com/sp4rkie/debian-on-termux/master/debian_on_termux.sh
this downloads the install shell script to the home folder..
update - download to home folder..
The
Debian 10/buster release key is 6D33 866E DD8F FA41 C014 3AED DCC9 EFBF 77E1 1517
Code:
wget https://ftp-master.debian.org/keys/release-10.asc
now check top of debian_on_termux.sh file.. has
#!/data/data/com.termux/files/usr/bin/sh
& you have to edit section.. # add the key for stable (Debian Stable Release Key) to..
Code:
...
# add the key for stable (Debian Stable Release Key)
apt-key add /data/data/com.termux/files/home/release-10.asc
# add the keys for testing, unstable (Debian Archive Automatic Signing Key)
#apt-key adv --recv-keys 648ACFD622F3D138
...
save file.. ;-]... comment out the keys for testing,.
execute the script..
Code:
sh debian_on_termux.sh
after some time.. 11mins for me... ]]..
list home folder..

NOTE: To compile programs with wiringPi, you need to add:
-lwiringPi
to your compile line(s) To use the Gertboard, MaxDetect, etc.
code (the devLib), you need to also add:
-lwiringPiDev
to your compile line(s).

Code:
#include <stdio.h>
#include <wiringPi.h>
// #define LED 0 matches with ASUS_GPIO 164! This can be checked with command 'sudo gpio readall'.

NOTE.. this is because you need to use
sudo ./bin/enter_deb or -0 for sysfs to control GPIO..
just remember not to install with apt or update... ]]].....
exit Debian to return back to android termux and run
Code:
bash:5.0][u0_a60]@~:$ sudo ./bin/enter_deb -0
root@localhost:~# cd code/pibrella/
root@localhost:~/code/pibrella# ./button.sh
maybe button is pressed [1] Time...;-]...
maybe button is pressed [2] Time...;-]...
maybe button is pressed [3] Time...;-]...
maybe button is pressed [4] Time...;-]...
maybe button is pressed [5] Time...;-]...
maybe button is pressed [6] Time...;-]...
^C
root@localhost:~/code/pibrella#
push the button & pibrella greenLED turn on with message..
ctrl+c to quit.. & use exit to go back to android termux..
sooo...
C GPIO library & Python GPIO library both are working in debian-on-termux environment.
next.. learn how to disable SPI / I2C / PWM & Serial on tinker Board..
I think this has something to do with device tree ?????? ;-]..
also.. setup..
vncserver for X11 server with
i3 tiling window manager,
but this is only because I have Logitech C922 pro Stream Webcam connected to laptop that I ssh into with
X forwarding to make videos using Mobizen App from android on tinker Board ;-]..
------------------
hope it helps
k,
debian-on-Termux via debootstrap & proot working on TinkerOS_Android 7 Nougat V14.3.2.82
next> GPIO & Tinker Board Device Tree..??? tbc..
