Hardware bug STM32F11 in Timer DMA mode (PWM Generation)

I wanted to generate PWM Waveforms with nucleo F411and found a severe bug in the hardware. Maybe it is described in the errata sheet, but I found nothing.bug:DMA is dependent on data send on DMA stream. Sometimes DMA transfer is not done. (DMA circul...

It seems that using the comparators with interrupts on the stm32f373 series with HAL drivers blocks the program in infinite loop.

I attach the full code as a file and the relevant part here - for the evaluation board STM32373C-EVAL in which the red LED blinks a few times until the comparator is activated and blocks the execution.Is there a workaround to make the comparator work...
