The above image represents logic analyzer output when HAL_SPI_Receive_DMA is executed. My doubt is regarding the single high pulse at MOSI line. During HAL_SPI_Transmit_DMA , no issues. Is this normal behaviour? STM as Full duplex master, i have disconnected the slave to check if it was responsible for the high pulse.
