We have customized board based on iMX6Q. In which we are using Marvell switch mv88e6176. In this switch port0 is connected with external ethernet, port 6 is connected with FEC controller of IMX6Q processor, port5 is connected with MAC of other board.
We got ethernet working on u-boot level and tftp is also working. But at kernel level we got below error while booting. "IP-Config: Failed to open eth0" and "IP-Config: No network devices available".
Initially it was failing because no PHY device. Then we make few changes related to fix phy our kernel. Now we are stuck at this stage. Any help or suggestion related to this issue will appreciated.
