ADSP-21369 direct DMA external ram to uart

I need to move large amount of data from external ram bank0/ bank1 through the uart in ADSP-21369, using DMA.

The platform is ez-kit and assembler.

The serial port 19 bits DMA addressing cannot get to the external memory, and therefore the only way that I found is to do two DMAs: one from the external memory to internal memory, and the other from internal memory to the uart.
Is there a better or direct way to do this job?
