OCTOSPI and MDMA - STM32CubeMX bug

[samob2703]

Hello!

I would like to report a bug. Using STM32CubeIDE 1.16.0 and the integrated STM32CubeMX 6.12.0 i encountered a bug regarding OCTOSPI and MDMA on STM32H723ZGT6 MCU. Inside HAL_SPI_Receive_DMA(handle, pdata); where the HAL_MDMA_Start_IT is called the destination and source pointers are/were swapped resulting so the DMA was writing 64 bytes into the DR register which was crashing my application. Swapping these 2 attributes fixed the issue and is now working as intended, below im adding the swapped code where the commented out line is the false one (incorrect one).

Thanks for your time. I hpe some ST employee sees this and fixes it but if not at least someone will be aware of the issue when he finds it on google
