We are having a custom board based on T1022 processor having two PHY (DP83867) attached to the processor via RGMII interface. The problem is none of the PHYs are getting detected at uboot using MDC/MDIO interface. We have checked the MDC using scope and it is OK, however there is no transition detected on MDIO line on trying to read through u-boot prompt. I am attaching the uboot log which includes RCW settings of the board.
Any other relevant information needed to debug the issue will be shared. Kindly let us know.
in your Board in LInux kernel RGMII with DP83867 worked??

how did you configured RGMII in Linux kernel??
