I am testing the example uart_edma_transfer for the SDK 2.0. On the FRDM K64.
I have modified the serial port, it is the 1 now. The pin mux are updated as well.
The buffer length is now 128.
I also initialize the tx buffer to some sequential numbers.
The source is attached.
I short on the board the PTC3 and PTC4, The pin 16 of J1 to the pin 4 of J2.
I see the data going out on the scope. The end of rx transfer is never got.
