    GPIO Sample issues on Raspberry Pi




      I tried to write a simple led blinking sample with brand new JavaME 8 SDK, nut I get following error:


      [ERROR] [DAAPI] iso=-1:There is unexpected error, when open GPIO pin 7


      Source code and overall procedure I followed is exactly the one depicted at page General Purpose Input/Output


      What can be wrong?


      BTW, same code works on Emulator Device (only by changing GPIO ID used).
