Usbx Azure rtos not working

[MDeva.1]

Hello,

I am working on Nucleo-h745ziq board. I initialize the azure-rtos h7 package, enable the Usbx and thread parameter .According the project that given in cubemx of Ux_Device__CDC_ACM accordingly I initialize the parameter only difference is that i enable the usb Fs instead of Hs .But i getting the error that shown in screenshot. For Usbx it is necessary to use the MPU.

In stm32cube ide in flash.ld we have compulsory add this below statements

  ._threadx_heap :

   {

     . = ALIGN(8);

     __RAM_segment_used_end__ = .;

     . = . + 64K;

     . = ALIGN(8);

    } >RAM_D1 AT> RAM_D1

Can some one help me. Because I first time working on azure Rtos. I did not have much knowledge of that.

Hi @MDeva.1​ 

Normally you should use the the "static memory allocation" as suggested by STM32CubeMX Config UI.

if it is the case in your project then do not modify the flash.ld file.

you can use the "Example Selector" from STM32CubeMX to inherit the UX_CDC_ACM application for the STM32H723-Nucleo board, then you can use it as refererence to configure your own project for the STM32H745i.
