FPU_Fractal in STM32CubeH7 Firmware freezes in STM32H747I-DISCO

[Joerg Wagner]

Hello, hello.

In the STM32CubeH7 Firmware Package V1.12.0 and earlier is a demo application

under Projects/STM32H747I-DISCO/Applications/FPU/FPU_Fractal.

The app waits in an endless loop in line 252:

while(pending_buffer != 0)
  {
  } 

A breakpoint in the callback function

void HAL_DSI_EndOfRefreshCallback(DSI_HandleTypeDef *hdsi)
{
...
}

is never reached where pending_buffer should be set to 0.

I also flashed CM4 and CM7 code. I did not test every example, some work.

Board version is: MB1248-H747I-D03

Did anyone try this example?
