Problems with the STM32_USB_HOST_LIBRARY generated by CubeMX

Hi !

First, I use the version 4.18.0 STM32Cube V1.0, and Atollic True Studio 7.0.1, so both are (normally) the last ones.

I try to generate, with CubeMX, a project on STM32F417VG, using several libraries, the STM32_USB_HOST_LIBRARY for MSC being one of them. My problem is that I cannot use this project !

I generate the project -> I compile -> Works !

I generate the project -> I add these lines in the main.h :

&sharpinclude ''usbh_def.h''

USBH_HandleTypeDef hUSBHost;

I doesn't change anything else, and I don't write anything else but it doesn't compile, I have some strange errors.

Four of them are about four different macros (USBH_MAX_DATA_BUFFER, USBH_MAX_NUM_ENDPOINTS, USBH_MAX_NUM_INTERFACES, USBH_MAX_NUM_SUPPORTED_CLASS) in the file ''usbh_def.h'' with this message :

Macro undeclared here (not in a function)

But those macros are declared in usbh_conf.h which is directly included in usbh_def.h.

Another error is :

USBH_DeviceTypeDef has no member name 'CfgDesc_Raw'

in this line :

0690X000006061iQAA.png

And when I go to the definition of USBH_DeviceTypeDef, I have this :

0690X000006061nQAA.png

So if we want CfgDesc_Raw, it's because USBH_KEEP_CFG_DESCRIPTOR == 1 (and I checked, it's true), but if we don't have it in the structure, it's because the same macro != 1...

What happened ? Why can't I use this library properly ? Do you have any solution I can try, please ?

Thanks !

Regards,

Antoine

Hello Antoine,

I could reproduce a compilation issue with Attollic, IAR and Keil but looks a bit different.

What is failing is the compilation of usbh_conf.c after adding the 2 lines in main.h

This seems to be linked to a recent change in code generation:

In generated stm32f4xx_hal_conf.h there is the line

#include 'main.h'

In older version of Cube there was instead 

#include 'mxconstants.h'

If I remove this include main.h, compilation of usbh_conf.c is ok.

The error I get is:

In file included from ../Inc/main.h:49:0,

from ../Inc/stm32f4xx_hal_conf.h:43,

from ../Drivers/STM32F4xx_HAL_Driver/Inc/stm32f4xx_hal.h:48,

from ../Drivers/CMSIS/Device/ST/STM32F4xx/Include/stm32f4xx.h:245,

from ../Inc/usbh_conf.h:55,

from ../Middlewares/ST/STM32_USB_Host_Library/Core/Inc/usbh_core.h:37,

from ../Middlewares/ST/STM32_USB_Host_Library/Class/MSC/Inc/usbh_msc.h:37,

from ..\Middlewares\ST\STM32_USB_Host_Library\Class\MSC\Src\usbh_msc.c:42:

../Middlewares/ST/STM32_USB_Host_Library/Core/Inc/usbh_def.h:281:44: error: 'USBH_MAX_NUM_ENDPOINTS' undeclared here (not in a function)

USBH_EpDescTypeDef Ep_Desc[USBH_MAX_NUM_ENDPOINTS];

Actually usbh_conf.h which defines the 

USBH_MAX_NUM_ENDPOINTS is itself including stm32f4xx.h which leads to include main.h. So in main.h you include a header file 

As a workaround I would suggest adding your lines in the main.c file if possible or create another header file if you need to share this with another source file.

Hi

WAJNTRAUB.Antoine

‌,

I tried the same using Keil and didn't got any compilation issue.

In order to be in the same configuration conditions, please share your IOC file. I'll give it a try using TrueStudio.

Then as general recommendation to generate Host example, please refer to UM1718:

  • subsection '6.6.5 Configuring the middleware'

  • Appendix 'B.3STM32CubeMX design choices and limitations for middleware initialization'
