I had an issues about EIGRP. But first, here's the topology :
I've done EIGRP Routing, but it's kinda strange. PC0 -> PC1 is able to ping, PC3 -> PC2 is able to ping. But, I can't ping PC0 -> PC2, PC0 -> PC3. This also happends on PC1. Here's my all of my router configuration :

It's seems the routing is up. But anyone know why this happend? Thank you.

I've created the same topology as showed on an image and put into routers your configs and I'm able to ping all PC's from PC0. All PC's have IP addresses in a same /24 network as routers Fa0/1 interfaces and all have default-gateways set to router's IP (192.168.x.254).
Configuration of Cat 3560:
Also I've created VLANs on switch:
