Re: [Discuss-gnuradio] How to update FPGA in E100

[xi yang]

Hi, Philip,

Thanks!

If I got a USRP1, what files do I need to copy to /usr/share/uhd/images ?

And that's it? No additional operations?

Hi, Nick,

Thanks a lot!
Do you know which file is same as usrp_std.v that is responsible for binding
all modules together?

This one:

fpga/usrp2/top/E1x0/u1e_core.v

I think.

Yooxi,

The USRP1 used an Altera FPGA. The USRP E100 uses a Xilinx Spartan-3A FPGA.
The FPGA code you want to be modifying is in the fpga/usrp2/top/E1x0
directory.

Hi, all,

We have made a FPGA FFT module.
We downloaded the UHD source code from
https://github.com/EttusResearch/UHD-Mirror/archives/master
We modified the usrp_std.v under
fpga/usrp1/toplevel/usrp_std/
to link our FFT module between rx_buffer and USB.
We have successfully compiled the usrp_std.qpf in Quartus II 9.1.
How can we make it effective in our USRP E100?

We found the way to update FPGA firmware in usrpe1xx-FAQ

http://ettus-apps.sourcerepo.com/redmine/ettus/projects/usrpe1xx/wiki/FAQ?version=30
But what we want to update is the FPGA code.

Thanks a lot!

Yooxi
