Can't program board: hw_server is probably down

Hello,

 

During some manipulation in xsct I put configuration staff in some "fail state".

Here is what I see when I try to program device in Vivado:

 

program_hw_devices [get_hw_devices xc7z045_1]
ERROR: [Labtools 27-3176] hw_server failed during internal command.
Resolution: Check that the hw_server is running and the hardware connectivity to the target

 

How to check if hw_server is running and if not how to launch it ?

Thanks.

Well ... I understood why it occured, but didn't find a remedy.

This failure caused by resetting of the ARM9 core in XSCT (rst command).

In the same time after issuing of this rst I can't no more program ARM (so I need reinitialize it).

 

Does exist some "safe" way to reprogram ARM9 and then rerun it ... without affecting logic fabric ?

Important remark:  logic fabric includes ILA instance.

Thanks.

Here is a "remedy", that I've found: issue these 2 commands in the Tcl console:

  • disconnect_hw_server
  • connect_hw_server

Anyway probably does exist more "smart" way to proceed at ARM9 side  (i.e. reprogram device and rerun application)
