disconnect_hw_server and connect_hw_server commands

Question

hello

i am using cmod a7 and for programing i am using vivado15.1 . 

when trying to program device or to connect to device it shows:

 No hardware targets exist on the server [localhost:3121]
Check to make sure the cable targets connected to this machine are properly connected
and powered up, then use the disconnect_hw_server and connect_hw_server commands
to re-register the hardware targets.

i have to restart my computer and then it works fine.but after programing and implementing once the error occurs again.any advice will be helpful .

thanks

>> vivado15.1

Are you sure?
This is my "Help/About Vivado" dialog of the latest free "webedition", which works for me without flaw for the CMOD A7:

If really "15" it sounds like a fairly old version.

i did install vivado 17.4 and it worked fine for first 3-4 times. but then suddenly it showed this error when tried to store bit file.

ERROR: [Labtoolstcl 44-199] No matching targets found on connected servers: localhost
Resolution: If needed connect the desired target to a server and use command refresh_hw_server. Then rerun the get_hw_targets command.
ERROR: [Common 17-39] 'get_hw_targets' failed due to earlier errors.

Hi @anurag,

When the Cmod A7 is connected please attach a screen shot of the device manage under ports and universal serial  bus controller? Did you download Adept 2? Does Adept 2 recognize the Cmod A7?

thank you,

Jon

Hi @anurag,

In adept 2 you can browse your computer to find the bit file. Once you have found the bit file are you able to program the Cmod A7 multiple times with Adept 2?

thank you,

Jon
