Can you please send me output of System.out.println("OS : " + " System.getProperty("os.arch")); on your pi3.

Hi Rishi, my pi 3 output is OS : arm

Hi Rishi,

I think I found the root cause. getCPUArch() in SerialComPlatform.java should check each line in /proc/cpuinfo, but in fact it only check the first line then return SerialComPlatform.ARCH_UNKNOWN.

I add some prints in SerialComSystemProperty.getOSName() and SerialComPlatform.getCPUArch(), the output shows below: OS name is: linux Is Linux os arch is:arm Property is processor : 0
