Hi Gregory, The problem is that I have only a USB console available at the moment and as I can see from the code it is the USB console which is calling dup2 after nxterm was already called dup2 for the stdio and stderr. I suspect this is the root cause of the problem. I would try with the serial console on my other board. Thanks.
