Why STM32F207 is getting stucked in Startup file, when im generating ethernet code from CubeMx 6.8.1

[JJhin.1]

Hello guys!

Now a days im facing issue with ethernet configuration in the latest version of CubeMx 6.8.1.

When im configuring the ethernet for my F207 nucleo board in its getting stucked into startup file. and through debugging when im pressing F5 button for manay times, then its getting out from startup file and my code starts working and getting pinged from my PC.

But when im generating code from CubeMx 5.4.0 version for same configuration, its working fine. im not geeting any issues with this version.

has anyone resolved this issue?

I have similar issue on STM32F746g-disco with CubeMX 6.9.2. Is there any solution for this case?

Hii @hbZhao ...

I'll suggest you to don't configure ethernet with latest version of CubeMX. 

You should have to configure ethernet manually using HAL libraries.

After digging more into this issue, i got to know that , after configuring Ethernet and generating the code through latest version of CubeMx then controller is not able to jump to main function.

IN THE MDKARM IDE:

If MCU is getting stuck after dumping the code, then you need to Change following settings in Manage Run Time environment:

after doing these settings presse ok and re compile the program and dump the code now Ethernet will work perfectly. 

for IAR Workbench Ide no need to change any settings it will work. for STM Cube Ethernet will not work with latest version of CubeMx.
