Problem in building micropython ( error in usbd_def.h)

[nikhiledutech]

Hey,

I am currently trying to build and flash micropython on STM32F4DISC board. After first few steps of building,
In micropython/ports/stm32/
when i execute the make and make BOARD=STM32F4DISC i get the following error.

the error goes on.
So how to remove this error ?
This type of problem didn't happened when i build the micropython few months before.

If anyone face same problem add the following files in usbd_conf.h file

#include "stm32f4xx.h"
#include "stm32f4xx_hal.h"

and save. And build again . It will successfully build micropython.

For the cited error messages, the following is sufficient:

#include <stdint.h>

Since a few weeks I have the same problem with the MP build, that is some compiles these standard types ar not known any more.

Okay. thanks sir.
