[Discuss-gnuradio] Details on the initialization sequence

[Gabriel Morel]

I'm looking for details about the initialization process of the FPGA as the order of lightsand their meanings. I studied the verilog files and significance of signal configurations. 

 

I think the CPLD program the FPGA and the FPGA turns on a light, the configuration signal DONE at the end of the program process, but I don't know which light.

 

But for the second light, I think it's the firmware that enables it.  The firmware is loaded from SD card by the FPGA after the DONE signals goes high.

 

So when I program my bin file in the usrp2, a single light illuminates. So I think my problem is not the bin file but the firmware. Is this possible?

 

I will come back next week with more details.  I will probe some pin and via to really understand the order of some signals.
