Dear Sir or Mandam,
I have some problem while configuring mpc5748g, eDMA, scatter/gather mode, attached is my problem.
In the following code in edma.c,
with the increase of the variable i, pDMA->TCD[channel].CITER.ELINKNO.B.CITER is always 2, and pDMA->TCD[channel].BITER.ELINKNO.B.BITER is always 18, they don't change with the increase of i.
The buffer to ben sent is dmaSampleBuffer "'This buffer is transferred via eDMA requests'\r\n", and when the programme ends, the receive buffer is only buffer "This buffer".
Could you please help me to find out what's wrong with my programme? How to make the receive buffer the same with dmaSample "'This buffer is transferred via eDMA requests'\r\n"?
Thank you very much for your help.
