Problem with threads , uGFX+ChibiOS_16.1.8.

[jaro]

I have problem with more than one thread in system witch uGFX and ChibiOS. If one thread is running all is ok, but if I start another thread I get error SV#4 from ChibiOS. Threads are very simple, first thread drive blinking led and second only realize delay in while() loop  100ms. Have anyone any ideas what might be wrong?

That is a better question to be asking in the ChibiOS forums as it does not really relate to ugfx. Try some of the pure ChibiOS test programs for threads. Similarly ugfx has a demos/modules/gos/threads test program to test ugfx's api abstraction of the underlying operating system.
