Hi, I'm trying to add an OTT block into the FPGA for an E320. I'm using version 4.0.0 of the UHD.
So far I've used rfnocmodtool to create the OOT folder structure and add my new block. My initial plan was to add this block as per the default code generated that just passes data through. I wanted see that this was instantiated into the FPGA and the system still worked before starting to add my own code. I've been following the "Getting Started with RFNoC in UHD 4.0" page on the Ettus website and also the Youtube video "RFNoC 4 Workshop - GRCon 2020". The .yml file I've created connects the OTT block between the radio Rx and stream endpoint (I've removed the DDC / DUC and already had the FPGA working without these). So far I've got the FPGA built and uploaded to the FPGA. Uhd_usrp_probe shows that the RFNoC routing as expected, but the name of OTT block has been replaced with Block#0. The OOT project appears as a folder in GNU radio with the new block available to be dragged into the project. I think the issues I'm now having are similar to those reported recently by Mike with the E310. Trying to run a GNU radio project results in the error " AttributeError: module 'Dilbert' object has no attribute 'dogbert'" The examples I'm following are all based around the X310, is there an extra step required for the E3xx USRPs to update the firmware running on the device so that it's aware of the new block type? If so I've no idea how I would go about this. Any help on this would be much appreciated, Mark ________________________________ This email and any files transmitted with it are confidential and intended solely for the use of the individual or entity to whom they are addressed.
