Example Selector: FatFs_USBDisk -> FatFs_USBDisk_RTOS

[FBerg.1]

I use NUCLEO-F767Z board and was working on a Application Framework that uses RTOS with different tasks, and logging to serial console and USBDisk. This is quite a while ago (STM32CubeIDE 1.6.1). I couldn't make USBDisk work with RTOS then. I switched to other tasks. But now I want to get back to this.

Now I see, that in STM32CubeIDE there is an example FatFs_USBDisk_RTOS. This might be what I need. But this example can only be selected for other evaluation boards.

Is it possible to port the example FatFs_USBDisk_RTOS to NUCLEO-F767Z for a newbee?

When I download the FatFs_USBDisk_RTOS example for a board which is supported, and look at the sources, then I can see that this is not using the API USBH_Init(), USBH_RegisterClass(), etc, .... - for integration with RTOS.
Therfore, I guess, there is no use trying to adapt and incorporate the FatFs_USBDisk reference into an RTOS project.
Will it be more promising to take FatFs_USBDisk_RTOS from another board and adapt that for NUCLEO-F767Z?

Just try it (should work)

It is matter of taste. The DMA interrupts are gated by the DMA config registers, so should not occur without reason.

If you prefer, disable the NVIC interrupt.
