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
Cherif

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

  https://github.com/EttusResearch/fpga/blob/fde2a94eb7231af859653db8caaf777ae2b66199/usrp3/top/x300/rfnoc_ce_auto_inst_x300.v<https://urldefense.proofpoint.com/v2/url?u=https-3A__github.com_EttusResearch_fpga_blob_fde2a94eb7231af859653db8caaf777ae2b66199_usrp3_top_x300_rfnoc-5Fce-5Fauto-5Finst-5Fx300.v&d=DwMFaQ&c=XYzUhXBD2cD-CornpT4QE19xOJBbRy-TBPLK0X9U2o8&r=xIsHdXnCRYoK3O7I17CLaka29UJ1VwI3mC9u8FAc7Ss&m=uyt3D3vrCo1sD1ffyQEPYhBW4X1kPu-ydtQoXIbEFIA&s=oWOA1dV-heZzHDmVnnGT9vrXUo3FwHl3BxJ3Eq3s6q0&e=>

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?

Brian
