    help! graphicstest example of 2.8'' tft screen, met error

    xiaoyang

      When I run the graphictest example of 2.8'' tft screen.

      I got infomation below from my serial moniter:

       

      ILI9341 Test!

      Display Power Mode: 0x9C

      MADCTL Mode: 0x48

      Pixel Format; 0x5

      Image Format:0x9C

      Self Diagnostic:)xC0

      Benchmark     Time(microseconds)

      Screen fill

       

      nothing was showing on my screen. Obviously, the program blocked.

      On my Edison terminal:

      [  480.610663] "echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message.

      Another problem is that how Can I add space to /dev/root?

      After I flush a new image (edison-image-ww18-ww15), I can only upload sketch.elf one time. If I tried to compile and upload next time, I got upload problem, saying "transfer incomplete, Retry, time out ...."
