Detailed Description

Stacked registers pushed by the Cortex-M exception entry.

Layout matches the basic (non-FP) stack frame described in the Arm Architecture Reference Manual section B1.5.6. The FPU variant adds S0..S15 + FPSCR but we log only the core GPRs – FPU state is rarely the root cause of a fault and makes the dump three times larger.
