First of all, you may need to upgrade to the latest versions of CubeFW and CubeMX.

Second, what is your SPI interface?

hi F.Belaid

i use the spi6. The spi tx uses the BDMA channel 0. The spi rx uses the BDMA channel 1. i use the stm32cubeide to make the project, and i use the HAL_SPI_Transelation_DMA to send data, but the data can't be send.

do you have the examples about the BDMA ? i don't find data about BDMA.
