Signal 'ET_ILLEGAL_RESOURCE' received??

As I already said before, a simple LED blinky code is working fine in debugger. I can step through the code lines ans breakpoints are ok too, but not the whole audio project.

And yes, its really strange ;-)

One of the differences between booting from flash and loading over JTAG is that when booting from flash the xscope link won't be enabled.

Could you try taking the -fxscope option out of the Makefile and commenting out the xscope link in the .xn file to see if that makes a difference? I wonder if there is some noise on the xscope link causing spurious network traffic.

Richard, that was the solution! No wI can debug my board as expected...

Great job guys and many many thanks!!!

Do you have appropriate pull down resistors on the XSYS connection for the xSCOPE link as documented in section M.3 of the datasheet? Or is this link even connected to the XSYS connector?

I think it is unlikely the channel end has received any data
from noise on the link -- unless perhaps it is using static
forwarding? It seems more likely it has data to deliver
instead; no pulldowns are going to help then, just don't
send anything if the link isn't connected ;-)

Either way, the xscope code could be made a bit more
robust it seems.

I have JTag only connection (M.2) and no pull downs on this pins.
