摘要: A fail-safe booting system suitable for a system-on-chip (SOC) automatically detects and rectifies failures in power-on reset (POR) configuration or boot loader fetch operations. If a failure due to a boot loader fetch occurs, a POR configuration and boot loader are fetched from a different non-volatile memory. The reloading takes place from further different non-volatile memory sources if the boot loader fetch fails again. The automated system operates in accordance with a state machine, and does not involve any manual, on-board switch selection or manual re-programming.
