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?
