Forum Post: RE: AM335X use uart dma and HW FIFO

Jeff or anyone else in TI:

Any further information on "It was showing some difficulties using DMA with UART" for that internal document?  Is this referring to problems with the driver or the chip?

I've attempted to enable DMA support with the UARTs, but the driver seems to have lots of problems with that.  Panics when enabled, unable to get the necessary DMA channels due to a conflict, attempts to use EDMA functions which the OMAP DMA wrapper indicate are not supported,...

I've worked through each of these problems, but I'd like to know the details of what sort of "difficulties" are known before continuing.


Thanks,

    Steve
