The

http://www.st.com/web/en/resource/technical/document/errata_sheet/DM00037591.pdf

describes a limitation with the DMA2.

''2.1.10 DMA2 data corruption when managing AHB and APB peripherals in a concurrent way''

Does the above note also apply on STM32F429 / 439? Have anyone tried to have more than two concurrent DMA2 transfers on STM32F429 / 439?

Is it possible to have 19 concurrent DMA transfers (16 peripheral DMA and 3 dedicated DMA)?

8 x  DMA1 channels

8 x DMA2 channels

1 x USB HS dedicated DMA

1 x Ethernet dedicated DMA

1 x DMA2D (LCD-TFT DMA)
