Jonathon, I have been working on this the last two days and can't seem
to get it working. My destructor looks like this:
dataGenerator_impl::~dataGenerator_impl()
{
std::cout << "In here3.\n";
uhd::rfnoc::dataGenerator_block_ctrl temp;
temp.issue_stream_cmd(::uhd::stream_cmd_t::S
What I did was instead of creating an enable flag, I used the PKT_SIZE
value I write when I execute a flowgraph to be my enable:
assign enabled = (PKT_SIZE > 0) ? 1'b1 : 1'b0;
assign o_tvalid = enabled;
That should work, right? If not, how do I know that initialization is done?
I didn't write
In the first screenshot you captured your block sending out a command
response packet. That is normal.
In the second screenshot, I couldn't see the full value of the header /
first word, so I cannot say if it had any issues.
Did you add an explicit enable for your block that turns it on after
ini
One last piece of oddball info I've discovered.

immediately and nothing shows up on the timesink. If I then stop it and
run it again, I get some data through, and t

I need to re-setup my debug messages to check. To be clear, you are
talking about the o_tdata (etc) up in my upper level
noc_block_dataGenerator, right?

Hey Jason,
Here is what should happen on the axi stream bus to the crossbar. You
should first see the header on o_tdata with o_tvalid asserted. After a few
clock cycles, depending on how long arbitration takes, you should see
o_tready assert. Are you seeing that sequence?

I am still struggling with my "output only" RFNoC block and can't seem
to figure out what silly thing I am doing wrong.
I am generating data by reading from a ROM and can see it happening by
monitoring the o_tdata (etc) lines coming from my lower module. If I
look in my noc_block_dataGenerator
