My situation is this:
I modified the UART pspdrivers_01_30_00_05 for SYS/BIOS6
There is a problem: When I call GIO_submit write first time, the data is transmitted normally. When the call again with the same parameters, the transmission does not occur. I experimented and when I resumed transmission via JTAG recorded in the register TX 8 bytes (trigger level), although the documentation it is written that the DMA event is generated for the first time when the FIFO is empty, and then when the FIFO = TH_trigger_level (in my example 5). When modifying PSP_UART with EDMA used the example UartEcho_edma
