[Discuss-gnuradio] Ram_loader VS CPLD VS firmware

[Gabriel Morel]

Hi, I need some help for ram_loader.v.  I have a bug with start-up of the usrp2 and I think that ram_loader module may be the problem.  Some process in that file aren't clocked.  Can somebody knowing verilog language help me.  I know some, bug i'm not a expert, can a state machine run without clock?

 

I think ram_loader have a problem because the usrp2 doesn't start with my u2_rev3.bin but the fpga is well programed.  So if the ram_loader doesn't work, the firmware can't be load.  Or the ram_loader works well with the cpld but the cpld can't read and load the firmware from the SD card.

 

I can write on the sd card , the usrp2 can load u2_rev3.bin but not the firmware.  So the problem is not the compiled binary file but can be the verilog program, the cpld or the firmware.

 

If somebody have an idea.
