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

[xi yang]

Hi, Nick,

Thanks a lot!

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

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
