The early logic to locate a free DMA channel and then set it up was broken in a few ways that only manifested itself when we needed to set up more than 2 on chip SRAM regions (most board defaults setup 1 or 2). First, we checked the wrong status register (the destination gets updated, not the source) and second, we did the ssync before rather than after resetting a DMA config register.
