To debug board support files using printk statements, use printk functions with the KERN_EMERG flag.
The printk lines can be shown on a serial console.
To enable the Android Debug Log, add the following line in the Android.mk file of your jni directory:
Inside JNI ‘C’ code use android_log_print lines in the following format to debug:
Example:
The debug lines can be observed on a serial console by using the ‘#logcat’ command on the serial terminal
If the android application does not respond, follow the steps below in the correct sequence:

Example: Printk(KERN_EMERG "MY PRINT LOG\n");
LOCAL_LDLIBS := -llo
#include<android/log.h>
#define LOG_TAG
__android_log_print(ANDROID_LOG_DEBUG, LOG_TAG,"PRINT LOG \n");
__android_log_print(ANDROID_LOG_INFO, "PRINT VALUE=", "%d\n", value);
a. Power off the iCE-Dragon Board by toggling the switch (sw1) to the OFF position.
b. Close the IR_scanner application process running in the background.
c. Power-on the board by toggling the switch (sw1) to the ON position.
d. Open the IR_Scanner application from the Android menu and the application is ready to detect any
