The RDB3 development board I use is developed based on BSP34 branch, and I want to configure pfe2 as sgmii. After looking at the schematic diagram, I find that the configuration can be done in the following ways, but how can I distinguish 1.25g from 3.125g? How can I configure hwconfig in these two cases?
Hello, @shiyiheng

For serdes0(mode3), it is not mentioned in the BSP 34 UM, but the following combination is supported on RDB3 based on latest BSP.
