硬件是MZ7035FB，刚到手的板子，按教材《ZYNQ裸机篇2019版》测试LWIP，可以老是卡在：
-----lwIP TCP echo server ------
TCP packets sent to port 6001 will be echoed back
WARNING: Not a Marvell or TI Ethernet PHY. Please verify the initialization sequ ence
Start PHY autonegotiation
Waiting for PHY to complete autonegotiation.
autonegotiation complete
link speed for phy address 7: 0
就没有反应了，把例程的下下去也是这样子，请问有没有高手指点一下呀？
