STM32H742XI QSPI MDMA CubeMX Setup

[CMA]

Hi,

I am attempting to communicate with a LAN9252 via QSPI and had success in a polling mode.

I've attempted to do the same thing with MDMA setup in the CubeMX, all default settings, and was unable to achieve communciation. From the use of HAL_QSPI_Receive_DMA, the SPI peripheral got stuck in HAL_QSPI_STATE_BUSY_INDIRECT_TX.

Is there a tutorial of some sort I can refer to for properly setting up the MDMA controller?

Thanks a lot.
