I'm trying to use the MultibufferDMA mode of HAL driver for STM32F769 device. There's not a single example I could find which uses this mode in the list all the applications/demos/examples for STM32 devices. Here's an example call I use :

 // using Double-Buffer DMADMA_HandleTypeDef hdma ;StreamBaseAddr = DMA_CalcBaseAndBitshift(&hdma) ; // get the stream base addr if (HAL_DMAEx_MultiBufferStart_IT(&hdma, StreamBaseAddr, Buffer[0], Buffer[1], BUF_SIZE))     {       Error_Handler();   ...
