I have this version UHD 3.15.0.git-84-g164d76dc

but the lines are there whenever you use the  ./uhd_image_builder.py scripts.

Best Regards

Hi Jerrid,

Some hints, for info,  I am working with the X310 device, but you can take the big picture.

I previously met  such issues, those were related to signal re-definitions.

The file *rfnoc_ce_auto_inst_x310.v* at lines 19/20 is re-defining the ce_clk/ce_rst signals by assigning to them  radio_clk/radio_rst signals. The issue here is that ce_clk is a clock of its own and is already defined in the top block file *x300.v* at lines 259 and 290. My filepath is rfnoc/src/uhd-fpga/usrp3/top/x300/.

In the code on github I don't see what you're talking about:


Looking at the history of the file, it looked like that might have been removed way back in 2016 in commit c98bc14fe0ea2c27a5629a24d47915eb7e0b6700.

Jerrid - do you have those lines that Cherif is describing?
