I've posted on this topic before, but this is a new case. I have 2 PicoZeds. They're identically configured, and have the same MATLAB boot image. I can ping PicoZed 1 from my Linux workstations, but I cannot ping PicoZed 2 (get Destination Host Unreachable). Have two Linux workstations, both at 192.168.3.3, and both PicoZeds are 192.168.3.2, using direct connect. I swapped which computer connects to which PicoZed. PicoZed 2 always fails ping, no matter which workstation it's connected to. I've also swapped boot images, still it's always PicoZed 2 that fails, regardless of which SD card is inserted.
What could it be? The only thing I can figure is that Picozed 2 has defective ethernet port. Has anyone else seen this?
