I've found in a forum the follow indication:
"The address is outside of any allowed code addresses in a Cortex-M4. The code has probably tried to use unprogrammed flash (0xffffffff) as a return address, see the contents of the link register (R14)."
How I can see the register? If I switch to debug prospective I can't access to any register

R14 (LR) is viewable in the register tab. Note you need an active debug connection to view anything on the device.
