Java on RIoTboard

Former Member

I have been attempting to get java running on the RIoTboard, but unfortunately it looks like the linux version that is available is only compatible with the softfloat version of JDK 1.7. From 1.8 they oracle have only been release hardfloat versions which dont work on this board. Is there a newer or alternative linux build for the RIotBoard that supports hardfloat?

Thanks,

    Fixed!

    The problem was that Java was referencing /lib/ld-linux-armhf.so.3 which does not exist on the system. When you look at /lib the only load file is /lib/ld-linux.so.3 so just soft link them and it works. Below is how I worked it out and what I did to fix it.
