Hi all:
I designed a board using XMC4800 as the controller and KSZ8001 as the ethercat phy.
The MCU works fine, and the Regs of the PHY can be read correctly with XMCLIB function, but the cable coonected to PC cannot be recognized, the net connection is broken.
I checked the net cable, cannot find any clue.
I do not know how to get out of the trap. Any idea about this problem? Thanks a lot.
