Debug token for Apollo Lake target

Jezic__Damir — Mon, 14 Oct 2019 14:57:55 GMT

Hello,

I'm not able to debug our Apollo Lake based target although our platform seems to be connected by System Debugger using CCA and USB3.0 port.
When I connect to our target and then when I press pause button in debugger then I get message "E-2201: Target is unresponsive":

IPC: DCI: Target connection has been fully established
INFO: Target power is now: Off
INFO: Target power is now: On
WARNING: attempting to halt an unresponsive target, this operation may fail…
E-2201: Target is unresponsive

I think that my problem to create debug token.bin by PFT to be able to debug our corebooot bios by CCA, because I need permission for this token.bin creation. Do I have right? Please could you provide this permission to me if this is what I need to be able to debug?

Hello,

Seems that I did debug token and properly stitched it, but now I see the next log before and after I start "Trace H/W test" in System Studio:

When I press pause button in debugger then I still get message "E-2201: Target is unresponsive".

Does anybody has any advice what could be the problem, why the target is always unresponsive although LED on CCA is green and status in System Studio is running?

No, "Found TAPs" list is

No, "Found TAPs" list is empty. So you have actually no connection to target. You are only connected to CCA adapter.

Did you enabled Debug Interface in BIOS?
