Msp430 Usb Firmware Upgrade Example [upd] < iPhone >

The bootloader’s reset vector is at 0xFFFE . Application vectors are relocated and remapped via bootloader’s interrupt vector table.

A USB firmware upgrade system requires two separate firmware images residing in different flash regions: msp430 usb firmware upgrade example

To implement a USB-based firmware update, you typically use a combination of hardware triggers and official software tools: The bootloader’s reset vector is at 0xFFFE

Follow these steps to validate your USB firmware upgrade: It requires a specific hardware invocation sequence

The MSP430 does not automatically enter BSL mode upon reset. It requires a specific hardware invocation sequence. Typically, this involves applying specific logic levels to the RST/NMI and TEST/SBWTCK pins during power-up or reset.
