I'm using Ubuntu18.4 and SDK_2.7.0_EVKB-IMXRT1050 + gcc-arm-none-eabi-8-2019-q3-update.

 

boards/evkbimxrt1050/lwip_examples/lwip_ping

This demo is working fine.

 

boards/evkbimxrt1050/lwip_examples/lwip_udpecho

But this demo failed to initialize, just have log: Initializing PHY...

We know that the code has been executed function enet_send_frame line 336 of enet_ethernetif_kinetis.c

result = ENET_SendFrame(ethernetif->base, &ethernetif->handle, data, length);
I've tried gcc-arm-none-eabi-9-2019-q4-major or gcc-arm-none-eabi-8-2018-q4-major,still have the same problem.


SDK_2.7.0_EVKB-IMXRT1050 for iar works fine in the iar ide.

 

Who can help me, thank you
