ARMv7 Reset Vector and Boot Process

The initialization of the stack pointer and PC pointer through the reset vector after power-on reset on ARMv7, followed by a jump to the assembly entry to begin system initialization and other operations, is crucial for embedded system software development. Although different SoCs may have variations in the address allocation of BootROM and Flash, the … Read more

Understanding the Power-On Sequence of MCUs

The power-on sequence of an MCU (Microcontroller Unit) is a carefully designed sequence that ensures the chip reliably transitions from a completely powered-off state to normal operating conditions. 1. Power-on Reset When power is applied to the MCU, the supply voltage rises from 0V to the rated operating voltage (e.g., 3.3V). The internal reset circuit … Read more
