Hey folks, I'm working on a modified rfnoc-devel FPGA image for the x310, which involves doing custom RFNoC blocks and modifying some of the existing too.
In the last test I made, I synthesized instantiating two of my custom blocks (one of them twice), plus some other modification to the AXI DMA FIFO block to use the SDRAM in a different way (no longer a FIFO). The thing is, when running usrp_uhd_probe I'm getting some errors arising apparently from a lack of response packets from my blocks. I'm attaching the log of the command output, and hoping you could answer some questions about it: * What can I be missing? I made sure rb_stb stays asserted, and I'm using the AXI Wrapper in Simple Mode and 64 bits width. The output (upstream) rdy to the AXI Wrapper only asserts under certain conditions, but I wouldn't expect any problem from that behavior. * You can see that the same "no response" error is repeated for several different CE_xx_Port_yy. Does it mean something's failing for more than one Computation Engine? And the names of the ports range all the way to the hundreds, what does that number mean? I hope I made myself clear, and you could give me a hand. Thanks, as always! Leo
