Hi list,I want to send data direct from the firmware without host. I looked at the tx_standalone.c and there came up some questions:
1. Do I have to encapsulate my data into a ethernet packet like it's done there or can I simply put something into the buffer pool and set the first_line-argument of the dbsm to zero?
2. What's this last_line-Argument for?3. Does the buffer pool or the DSP delete the data out of the buffer after sending?
4. If the ethernet header is necessary, which fpga component interprets it? The buffer pool or the DSP?
kind regards, Matthias
