Hi Jan, We set all but a few IRQ handlers to "os_default_irq_asm" on initialization. What you have to do is to set your handler with:
NVIC_SetVector(DMA2_Stream0_IRQn, (uint32_t)DMA2_Stream0_IRQHandler); NVIC_EnableVector(DMA2_Stream0_IRQn); PS: No need to use the "HAL_" macros from STM32Cube for this...
