Si5324 AC701

Hello, 

 

I followed the tutorial 

https://www.xilinx.com/support/documentation/boards_and_kits/ac701/2014_4/xtp231-ac701-si5324-c-2014-4.pdf

 

But at the oscilloscope I see the output not a clock but a signal :

Please suggest me, what is going wrong or how should I proceed.

 

Thanks

Re: Si5324 AC701

Does it work before you re-program it?

Re: Si5324 AC701

I have no way to know, as without flashing the board the output voltage is zero.

 

After I flash the hardware with ready to use .tcl file i.e. bit and .elf from Xilinx, I couldn't see the expected clock on the oscilloscope. 

 

Is it possible to check this? and how? 

 

I don't know how to proceed further.

Re: Si5324 AC701

If I take clock wizard, then generate a clock of 100Mhz from clock wizard. Later fed the SMA connector via OBUFDS then I can see a perfect clock. This implies SMA GPIO are working and oscilloscope station is also good.

Re: Si5324 AC701

the tcl script which comes with the xilinx example :


open_hw
connect_hw_server -url localhost:3121
current_hw_target [get_hw_targets */xilinx_tcf/Digilent/*]
set_property PARAM.FREQUENCY 15000000 [get_hw_targets */xilinx_tcf/Digilent/*]
open_hw_target
set_property PROGRAM.FILE {C:/Users/HussainS/Downloads/rdf0229-ac701-si5324-c-2015-1/ac701_si5324/ready_for_download/si5324_bypass.bit} [lindex [get_hw_devices] 0]
current_hw_device [lindex [get_hw_devices] 0]
refresh_hw_device [lindex [get_hw_devices] 0]
program_hw_devices [lindex [get_hw_devices] 0]
refresh_hw_device [lindex [get_hw_devices] 0]
disconnect_hw_server localhost:3121
close_hw

 

In this only see that .bit file is flashed. How does this tcl script take care of flashing .elf file ?

 

thanks
