I have a problem with xscope hanging when it is booting a multi-tile custom board. The board has an L16 and a U8 part in a linear chain: xtag2 -> L16 -> U8.
When I run a simple program using xrun --io it boots and runs normally (with the updated XTag firmware from https://www.xcore.com/forum/viewtopic.p ... 4&start=10). If I run the program with xrun --xscope, then the boot process never completes, and there is no response from the target (the child xgdb spawned by xrun on Windows then consumes approx. 20% of the cpu until it is killed manually).
I have included the verbose output, and you can see it loading the images to the cores and then stops at the end with "Enable xscope on core 2 at address 0x1069c" and there is then no further output.
Is this a known problem that has been seen before, or is, perhaps, some routing issue it my XN file? There was a fault in the XTAG firmware that XMatt in the referenced forum thread posted a fix for the basic booting of the multi-tile board, and I just wonder if there is a similar fault in the xscope mechanism where it is enabling the routing between tiles.
In case it helps I have attached the simple demo with its source, xn file, and makefile.
any thoughts and things to try would be appreciated,
thanks
