Current version of HAL drivers optimize IRQ handler by using precalculated DMA register address and stream bitshift instead of calculating it on every interrupt. Since we skip call to `HAL_DMA_Init` on reused DMA, fields StreamBaseAddress and StreamIndex of DMA handle are not initialized and thus leads to SegFault in `DMA_IRQHandler`. HAL_DMA_Init is a big routine and we do not need to call it on each use of DMA (ex.: series of I2C operations) and DMA_CalcBaseAndBitshift is really small and releasing it increases code size by only 8 bytes. |
