wiringPi for Android

[fited]

I tried now to integrate the serial part into an app and it works so far. I think you missed to chmod the serial port:

Code:

chmod 666 /dev/ttyS1

If you need this at start, I see the only working solution so far to extract the boot.img and to modify the ueventd.rk30board.rc.

Hi lobo!

I use same method from http s://tinkerboarding.co.uk/forum/thread-671.html
And add next line

Code:

/dev/ttyS1                0660   system  system
# also i try 0666 value, but without success result.

to ueventd.rk30board.rc.

But without command

Code:

chmod 666 /dev/ttyS1

in adb wiringPi not works.

Android M V13.13.0.74.

Note:
I copy file from my TB to desktop

Code:

adb pull ueventd.rk30board.rc /Users/user/Desktop/test

and it contains my line with correct permission for /dev/ttyS1
