Hi Andrew,
Have you tried using Chipscope to see where the issue is at in your code?
You want to look at the tvalid and tready AXI stream control signals to
pinpoint where your data flow stalls (i.e. tvalid = 1 and tready = 0). Once
you know where the stall is located, I can provide more advice.
Some more thoughts...
Are you programming the axi_rate_change SR_N, SR_M, and SR_CONFIG registers
when you run on hardware? You might be able to do this with the XML
definition, but you may also need a block controller like the
ddc_block_ctrl_impl in uhd. Don't forgot the config register-- this
Thanks for the reply. I do set simple_mode and I propagate tuser into and
out of axi_rate_change the same way noc_block_ddc does. I also have my
block running properly in Vivado simulation. Is there anything else I
should check? I also included axi_tag_time. Could that be causing an issue?
You can do "make GUI=1 X310_HG" to open the Vivado GUI and build the
project.

Hi all,
Will running "make X310_HG" generate a .xpr file that I can open with
Vivado? I have a .xpr for the E310 from a previous effort so I think it can
be done, but I wasn't the originator of this file.
I was following this guide:

Do you really need to install uhd on a machine to install an sdk on it?

Hi Andrew,
Quick thoughts:
- Are you setting SIMPLE_MODE(0) in the axi_wrapper?
- Are you propagating tuser into and out of the axi_rate_change block?
The axi_rate_change block updates tuser, which the axi_wrapper uses to
create output packets when SIMPLE_MODE is disabled.
Also, have you run in
If I recall correctly the only place QT is used would be in the RFNoC
Fosphor host code to display the fosphor output. This typically runs on a
PC, not an embedded device like E310 or N310. Unless you really need to use
QT on the N310, definitely the easiest solution here would be to just
disable
Hi all,
I'm trying to create an rfnoc block that takes in a stream of data at
Sample rate n, does some processing to turn i-q values into real samples,
and outputs data at a rate of n/2 by packing real values into both i and q
channels of the output stream. I've tried to incorporate the

It looks like qt4 was not included in the cross-compile build. If I look at my

Dear Marcus
The problem is solved by setting RF policy manual for RF and DSP both and
passing uhd::tune_request_t object as parameter to set_center_freq function,
but now i getting one more issues that after 35-40 iteration my application is
getting assertion because of "EnvironmentError:
