I always need to replug, reboot or press the refresh list button several time for it to work
Is it possible to update the firmware on xtag to solve the problem?

It always end with "target connection failed"
Any ideas ?

I add XMOS_XTAG_WINDOWS7_STARTUP_TIME with the value 500 and reboot the system, but nothing change. Debugger can be used several times without error and then without any modifications it cannot be used. I have to plug, unplug many times before I can use it againmon2 wrote:Personally believe the USB IP is not perfected. The IP is held in OTP ROM so cannot be changed. Based on using many other USB driven kits from different vendors, really should not have to jump through a ring of fire followed with a walk like a poodle on front 2 paws before this all works. Other vendor kits are working fine using the same set of parameters and physical box - often with longer USB cables.
You can try to the delay variable noted for Windows 7 use which may help out on Windows 10:
