I am calling the driver from an Android program (OMAP4/Blaze). It calls a c++ program via JNI which then calls the device driver. When I open the driver and write to it, I get a 'bad file number' error. Someone suggested it might be a permissions problem - the program is running in user mode.
on Blaze board, /system/bin # ls -l -rwxrwxrwx system system 7636 2011-09-30 03:53 mydriver What permissions does AndroidManifest.xml need to access a custom device driver? Anil -- unsubscribe: android-kernel+unsubscr...@googlegroups.com website: http://groups.google.com/group/android-kernel
