[Discuss-gnuradio] About EEPROM and FX2(68013a) USB interface in USRP

[Liang Xin 梁昕]

Hi All

 

I am developing a board with gnuradio which is like USRP. It is also use FX2LP(CY7C68013a) and AD9862, and I add some surroundings. 

 

I hope that my board can work well with gnuradio, but it seems like it can only support USRP now.  So could you please give me some help, if I want to run gnuradio on my board. How should I do with it?

 

Now I do some test with my board. ----------------------------------------------

 

When I plug the board to host and run command :  lsusb

the information list as below:

 

Bus 002 Device 003: ID 0b4:8613 Cypress Semiconductor corp. CY7C68013 EZ-USB FX2 USB 2.0 Development Kit

 

When I plug the USRP it shows

Bus 002 Device 003: ID 0xfffe:0x0002

 

My board is recognized by PC, but VID and PID is different from USRP. What's the problem with it?

It means the driver(s) is not correct? Or I should change something in the source or head file?

 

PS: I don't configuration EEPROM with CY7C68013a now. Does this cause some issues? Should I leave it blank? If not, what and how should I burn in it?

 

---------------------------------------------------------------------------------

When I run benchmark_rx.py, it shows "Fail to automatically setup a usrp device".

I think it make sense, because the PC doesn't find USRP anyway.

 

 

Thank you guys all!!

 

Best Regard
