CubeMX5.6 lwIP code generated for stm32f407 discovery board doesn't compile in KEIL 5.29 Arm Compiler 6.13

[naser moravej]

Hello everyone,

I generated a code for having ethernet on stm32f407 discovery board.

I just enabled lwIP and ethernet in cubeMX and nothing more.

when I compiled the generated code in KEIL 5.29 Arm Compiler version5, everything is OK, but when I change compiler to Arm Compiler version6, I got this error. I've got 83 errors because of missing <sys/time.h>

Thanks for you're answers.

Hi @naser moravej​ 

Could you please share your .ioc file to check the issue.

Please tell me which STM32CubeMX version do you use.

Best regards,
