CubeMX FREERTOS CMSIS_V2 LWIP - RTOS Dependency

[Joe94]

Hello,

 

what do I wrong? 

 

I am trying to setup a new stm32f7xx project, with CMSIS_V2 and LWIP.

I use only the CubeMX application at the version 6.15.0, I have tried several hours to get this setting but nothing working.

If I select CMSIS_V1 the LWIP use the RTOS (WITH_RTOS is Enabled), if a switch to CMSIS_V2 it is disabled.

All settings are CubeMX default.

 

CubeMX says CMSIS_V2 is working with F7.

 

 

Is this a bug at the CubeMX? Or what do I wrong?

 

 

thanks a lot.

worked for me after enabling ETH and some  PHY. See attached .ioc

If you stll have trouble, specify your MCU and attach your .ioc.

Hay,

 

yes I have tried it with the STM32F746 I can also select CMSIS_V2 and LWIP, but not with the STM32F767 :(

Hello @Joe94, and welcome you to ST community,

The STM32F7 LwIP implementation provided by CubeMX and CubeFW currently does not support CMSIS V2. This is why when you switch to CMSIS V2, the LWIP RTOS integration (WITH_RTOS) is disabled, causing the issues you are experiencing. The existing STM32F7 LwIP stack is designed around CMSIS V1, so full CMSIS V2 compatibility is not available for this platform. Thank you.

Best regards,

Hello,

 

When will LWIP be updated so that CMSIS_V2 is possible?

Do you know this?

 

Thanks :)

Hello @Joe94,

Thank you for your patience. After checking, there is currently no planned update for LwIP to support CMSIS_V2 on the STM32F7 series.

 

Best regards,
