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:
If you are going to do something completely standalone, there is no need to use ethernet. Just send packets to the DSP Core.
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?
Last line tells the buffer pool how big the packets are.
3. Does the buffer pool or the DSP delete the data out of the buffer after sending?
It is automatically cleared.
4. If the ethernet header is necessary, which fpga component interprets it? The buffer pool or the DSP?
Ethernet is not necessary. Matt _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
