DMA1_Channel7_IRQHandler doesn't get called HiI am trying to do a simple USART communication via DMA (LL Drivers). I want to send two chars to my STM32F103 from my PC which are received by DMA. In the DMA RX transfer complete callback I want to send some text string, also via DMA back to the sender.For that I wrote extra functions to send the text and to clear the text buffer once the DMA TX has completed the transfer.Receiving the two chars works without problems.Sending text back to the sender also works, but then the DMA1_Channel7_IRQHandler doesn't get called and subsequently all actions that rely on TX Transfer Complete signal don't work anymore, like clearing my TX-text buffer.The buffer for the two receiving chars:char rxBuf[2];configuration of my reception DMA:LL_DMA_SetMemoryAddress(DMA1, LL_DMA_CHANNEL_6, (uint32_t)rxBuf);
LL_DMA_SetPeriphAddress(DMA1, LL_DMA_CHANNEL_6, (uint32_t)&USART2->DR);
LL_DMA_SetDataLength(DMA1, LL_DMA_CHANNEL_6, 2);
LL_DMA_EnableIT_TC(DMA1, LL_DMA_CHANNEL_6);
LL_DMA_EnableIT_TE(DMA1, LL
