LWIP stack won't initialize

[haohailantianha]

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

I seem to have solved the problem. I use SEGGER firmware running on the NXP OpenSDA platform which makes OpenSDA compatible with J-Link LITE. https://www.segger.com/products/debug-probes/j-link/models/other-j-links/opensda-sda-v2/ 

I don't know why I use OpenSDA, lwip_udpecho demo won't initialize, but lwip_ping demo doesn't have that problem.

Hi feng zhang,

  Thanks so much for your updated information, and let me know it is related to the on board debugger.

   Do you test the on board CMSIS DAP firmware, whether it also have the problems or just the JLINK firmware don't have the problems?

Best Regards,

Kerry

Hi feng zhang ,

   Do you follow the Getting Started with MCUXpresso SDK for EVKB-IMXRT1050.pdf in the SDK doc folder?

   Please refer to chapter 5 Run a demo using Arm® GCC.

  

Do you try 4.9 2015q3 version?

Wish it helps you!

Have a great day,
Kerry

Hi feng zhang,

  Thanks so much for your updated information and let me know the details.

  I will check it on my side, if it is confirmed the problem, I will report it to our related department.

   Do you try the windows version for the same project, whether it works on your side or not?

  BTW, from tomorrow, I will be on the Chinese Spring Festival, and will back on February 3.

Sorry about it, and if you have any updated information, maybe I will reply to you after I am back to work.

Have a great day,
Kerry
