I design my own carrier board using ccimx6ul SOM. I download the standard ccimx6ul SB Express firmware from digi website and I can boot the device to u-boot using the USB debug mode boot. But I cannot get the ethernet to work (dhcp, ping, etc). I notice that the Interrupt and Reset pin for Ethernet port were changed. Can anybody help me? You can check my device tree in Pastebin link below. Thanks in advance.
