XScope on XK-1A

[PetrStrnad]

Hello,

I'm trying to get the XScope running on my XK-1A through XTAG2. Without XScope, the programs (be it my own, or the app_xscope_printing_timed_example from XMOS) run without problems, and if I remove the config.xscope file, I even see the printf output in the console.
Problem is, whenever I switch in the XScope tab of Run Configurations to either Offline or Real-Time, the program hangs on startup. I tried both Run and Debug with same results, and when I press Suspend in Debug to see where the program is waiting, it shows xscope_constructor().
Is there something I'm missing? It looks like either the device can't connect to the XScope server, or I'm supposed to somehow tell the server to start the app, but I don't see where.

The Run Configuration I'm using:
(I also tried the "xSCOPE (via xCONNECT/UART)" in the "Target I/O options")

Xscope is broken, and looking at the forum XCORE has zero support staff so dont count on any help here.

Last time I used IO redirection in Xscope I think I had to add initialisation :

Code: Select all

void xscope_user_init(void) {
   xscope_register(0, 0, "", 0, "");
   xscope_config_io(XSCOPE_IO_TIMED);
}

You could try adding that, however, I tend to use command line rather than xtimecomposer though assuming your setting are similar results should also be.

You can initialise like this or by specifying configuration information in config.xscope file.
