Hi Marcus,
I tried axi_wrapper in both SIMPLE_MODE and advanced. When not in
SIMPLE_MODE, I setup s_axis_data_tuser like this:
wire [63:0] vita_time;
wire has_time;
wire eob;
wire [1:0] pkt_type;
wire [15:0] length_adj;
assign has_time = m_axis_data_tuser[125];
assign eob = m_axis_data_tuser[124];
assign pkt_type = m_axis_data_tuser[127:126];
assign vita_time = m_axis_data_tuser[63:0];
assign length_adj = (4 + (has_time ? 16'd16 : 16'd8));
assign s_axis_data_tuser = {pkt_type, // DATA packet
has_time, // Has VITA time field?
eob, // End of burst
12'd0, // Don't care, AXI wrapper
handles sequence number internally
length_adj, // ... and packet length
src_sid, // Source SID (aka this block
port's SID)
next_dst_sid, // Destination SID
vita_time};
(where src_sid and nex_dst_sid are outputted from the noc_shell)
The length_adj seems odd to me, but I've had to use it in the past when
I was doing vectors (it would be 4*PKT_SIZE), should I do something
different there for a stream?

Sounds like the header might have not been adapted 100% correctly.
Check whether your noc shell has the right fields set.
Cheers,
Marcus

I am splitting one of my RFNoC blocks into two different ones, and one
of them is giving me issues. The block is essentially a keep m in n
block, so I only spit out data once in a while. This worked fine when
combined with my other block, but now when I run it independently, it is
throwing this error whenever I send the samples across (one error
message per dump of data it seems:
[RFNoC Streamer block received error ERROR] ERROR_CODE_BAD_PACKET[
(Code: 0xSTREAMERf] )The receive packet handler caught a value exception.
ValueError: Bad CHDR or packet fragment
Any idea the best way to debug this?
