Actually, I'd read the documentation when installing on my atom. However, still couldn't get this to work with the arm system. And the odd thing was that it was fine with the same busybox build and configuration. I did get a bit further in debugging though - the only difference between the two were the bash shells. The atom bash was a known quantity, but I dont know what they did with the bash on the arm core. Switching from bash to ash on the arm core got the simple scripts running fine. Curious as to how bash is knocking it on the head though. Thanks for the quick replies - it got my head cleared enough to keep debugging :) Regards, Daniel Stonier.
