Hy all!

I have a problem with CubeMX and sd card init with dma channels. I check that all of the sd card example project has 2 dma stream for sd card communication. So that I would like to set DMA2_Stream6 for Tx and DMA2_Stream3 for Rx but CubeMX does not allow to do this. What can I do in this situation?

Thanks

Hi toth.janos,

Have already configurated your DMA2, by adding SDIO DMA requests for DMA2 Stream3/6 ? Which STM32CubeMX version are you using ? and with any STM32 MCU serie ?

With regards,

Heisenberg.

I can configure only TX or RX stream whit stmcubemx 3.1.0 and stm32f407ig.

But now I check the 4.0.0 and this is support both streams for rx and tx. So the pro blem solved with the new cubemx.
