TMS570LS3137: Problem appending to TX descriptor list.

 

Please provide a simple example of how to append to an active TX descriptor list without using interrupts. Or provide comments to previously provided code as to why it does not work.  The TRM indicates this can be done and how to do this, but the provided solution does not work.  Processing of descriptors stops at the end of the current list without transmitting the appended portion.

Please don't provide an example that uses interrupts. Please don't provide an example that appends to a list that is not yet active.  Please don't provide an example that stalls software for the current list to end.  Please don't use a small first packet that completes before appending the second packet.  These are all examples you used to indicate the hardware works, but it does not duplicate our conditions.

Sorry for the tone, but this has been going on for way to long not to have a solution.
