EK-TM4C1294XL: What is the maximum length of DMA transfer from memory to UART please?

Hi Ping,

  Please find below description. The maximum size is 1024 bytes. 

9.2.5 Channel Configuration
The μDMA controller uses an area of system memory to store a set of channel control structures
in a table. The control table may have one or two entries for each μDMA channel. Each entry in the
table structure contains source and destination pointers, transfer size, and transfer mode. The
control table can be located anywhere in system memory, but it must be contiguous and aligned on
a 1024-byte boundary
