Hi everyone,
Is there any bus error or memory error would occure if dma and cpu core access the same address at the same time? I want to trig dma to move data by external signal, and cpu may requier the data at the same time.
Thanks.

There will be no error occur, dependent of the data location the CPU will access first then the DMA or first the DMA access then the CPU.
