I'm still building / tweaking my Cortex PC to drive to as low-consumption as possible. It's an EPIA EN1200, currently in an available ATX chassis.
Till now, it's been powered by a spare 400w ATX PSU but I am trying to change this to a silent 60w PSU set, complete with laptop-style brick, from linitx (this one).
But, either Cortex, the motherboard or PCA fails whenever I try it.
It continually reports hardware errors and tries resetting the PCIF then cycles... and cycles. Swap the 400w ATX PSU back and it's all fine again.
The power source is the ONLY thing that's different. The only other device drawing power from the active PSU is a 2.5inch SATA HD, so I can't be overloading the PSU.
My best guess is that is a ground-related issue causing the PCD problems , but I'm at a loss to work out why - I've even tried leaving the ATX PSU in the chassis with mains cable connected in case the chassis needed a route to mains earth maintained. The rest of the Idranet connected parts are either idranet-only or supposed to be isolated so the change of PC PSU shouldn't affect it.
Below is the output that cortex shows... sorry it's long, but you'll get the idea that it just repeats....
Has anyone got any ideas or seen anything similar ?
Edit: I'm using UNshielded twisted pair for the Idranet bus
