USBX System Stack Size is missing in USBX Configuration on STM32H7RSxx

[Gaweringo]

The X-CUBE-AZRTOS-H7RS middleware is missing the setting to change the USBX System Stack Size which in turn means that the USBX_MEMORY_STACK_SIZE define in the app_usbx.h file can not be changed from its default of 1024. And because the define is not in a USER CODE section, any manual change will be overridden when re-generating code in CubeMX.

Here is an example when using USBX host stack, but it's the same for the device stack.

Hello @Gaweringo 

Let me thank you for posting.

I am currently checking this behavior, and I will get back to you ASAP.

For more investigation, I suggest please that you provide your Ioc.File

Thanks.

Here's an exemplary .ioc file. It's not configured in a way that the resulting project would work (sizes aren't large enough, time source isn't changed from SysTick, ...) but UsbX is activated and doesn't show the option to change the USBX_MEMORY_STACK_SIZE.

I have also attached a .ioc file for a h7a3 where the option shows up.
