Run avrdude on Android with Samsung devices

Question

Hi members of stackoverflow.com!

I try to build an app in Android that can upload HEX file generated by avr-gcc. I installed the AndAVR this chaintool http://code.google.com/p/andavr/

to run avrdude (in root devices with USB-OTG cable) I use this command in mobile terminal:

/data/data/jackpal.androidterm/local/bin/avrdude -F -V -c arduino -p m2560 -P /dev/bus/usb/002/001  -b 115200 -C /data/data/jackpal.androidterm/local/etc/avrdude.conf -U flash:w:/sdcard/megademo/Blink1.cpp.hex

and after Read this post Android cannot talk to Arduino using AVRDUDE I try the solution and change the /dev/bus/usb/002/002 by /dev/ttyACM0.

/data/data/jackpal.androidterm/local/bin/avrdude -F -V -c arduino -p m2560 -P /dev/ttyACM0  -b 115200 -C /data/data/jackpal.androidterm/local/etc/avrdude.conf -U flash:w:/sdcard/megademo/Blink1.cpp.hex

But avrdude answer me with:

avrdude: ser_open(): can't open device "unkown". No such file or directory.

I have a Arduino Mega 2560 and Mega ADK 2560 R3, both boards have a ATmega2560 microcontollers and I have a:

Samsumg Galaxy S2 run Android 4.1.2 stock with root
Samsumg Galaxy S3 run Android 4.1.2 stock with root
Samsumg Galaxy Tab Note 10.1 run Android 4.1.2 stock without root
Asus Transfomer Pad TF700T run Android 4.2.1 stock without root

the problem is that Samsung devices doesn't enumerate the Arduino board and the Asus tab yes.

In all devices I run the command in mobile terminal:

cat /proc/tty/drivers

and Asus present the specific driver:

ACM /dev/ttyACM 166 0-31 serial

this driver doesn't show in Samsung devices, well this driver is essential to upload the hex file to Arduino board, so How can I install this driver in Samsung devices? or how can I upload the hex file?

Android in all devices create a file in /dev/bus/USB/002/xxx where xxx is the Arduino board or other USB device.

Best regards!

If you want to use this method, you need to load the cdc_acm kernel module - which probably was not supplied with your device, so you will have to build it. And then create the corresponding /dev/ttyACM0 device node, since the daemon that would do that on a desktop linux probably isn't there. You will need root to do these things, and moderately close kernel sources to compile from.

Another approach might be to implement CDC_ACM type communication in user mode from an Android app using the Android USB Host APIs if those are supported on your device. This would be a more "android style" solution, but would require some changes to avrdude, since it will have to do communication via an Android-aware backend service packaged in an app.

Also note that CDC_ACM is used by the recent arduinos (Uno, etc) and a minority of clones; older Arduino boards and the majority of clones use FTDI USB-serial converters and require ftdi driver modules or protocols.
