I have a custom board using the AM3359. The serial port /dev/ttyO1 that originally is used by bluetooth, It's used by another device in my board. I'm using Android ICS and I removed all associations of this port with bluetooth (at Init.rc and board-am335xevm.c). I can see the root as owner of the device (before the owner was bluetooth). In board-am335xevm.c the uart pins are correctly configured and bluetooth init's was removed. I'm trying access this port using JNI in android without sucess (using open command the return is always -1, for all ports). In Android shell I have tried use this command "cat > /dev/ttyO1" but no data is out. Someone can give me some advices to solve this?
