missing first character when setting up SCI to use DMA frame transfer with hardware trigger.

Other Parts Discussed in Thread: TMS570LS1224

I am using a TMS570LS1224. When I set up a DMA channel to transfer characters from the SCI receive register (sciREG->RD + 3) it always misses the first character. All following characters are received with no problem except the frame count is off by one because of the missing first character. The DMA channel is set up well in advance of any characters being received.
