Unable to determine board revision from /proc/cpuinfo 메시지 에러를 내면서 프로그램 중단




무슨일이지 ? 아래와 같은 메시지와 함께 어제 밤부터 돌아가던 프로그램이 중단되어 있어 검토중이다.

참고 사이트 가봐도 좀 어렵다. https://www.raspberrypi.org/forums/viewtopic.php?p=184410#p184410

Hi,
thanks for the answer. in the mean time i found out the problem.
It was my own mistake. i'm calling a c funktion from java over jni. In this c funktion i call setupWiringPI(). So everytime i call this funktion, i open a new file /proc/cpuinfo. That was the cause. After a long time i opened too many files and the system crashed. Now created a new JNI funktion just for setupWiringPI()..










더욱 좋은 정보를 제공하겠습니다.~ ^^
