Hello,
I am running FreeRTOS Multitasks application.
Actually, I am using the DMA1 channel 4 and 5 for SPI transfer and request #1.
Now, I wonder if I can run in parallel USART DMA using the same channels (4 and 5) but they are linked to another request #.. #2.
So, can I have some issue to enable both? For example, I can wait data on UART lines for few seconds and in same time, I am using the SPI to communication with a device using the same DMA channel.
Thanks for your help

I found that I can map UART to DMA2 channels 6 and 7. So, I will not have any conflict.
Thanks
