    GPIO Sample issues on Raspberry Pi

    user8032606

      Hi.

       

      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).

       

      Thanks!
