There is a reset or interrupt source called "CM4 is in lockup". But what I cannot find in the Vybrid manual describing when can this happen.
When and why can this happen?

Hi Yuri,
ARM M4 manual says "..The processor enters a lockup state if a fault occurs when executing the NMI or HardFault handlers. "

Thus it shouldn't be in the state just after system reset.
