Here’s a structured technical text explaining an , covering the concept, required components, and a basic implementation flow. MSP430 USB Firmware Upgrade Example Overview Many MSP430 microcontrollers (e.g., MSP430F55xx, MSP430USBxx families) integrate a USB module. This allows in-application firmware upgrades via USB without requiring a dedicated programmer (like JTAG or Spy-Bi-Wire). The process is often called DFU (Device Firmware Upgrade) . // Function pointer to application void ( jump_to_app)(void)

// USB command handling (example) void USB_handle_commands(void) if (received_cmd == CMD_WRITE_FLASH) uint8_t* flash_ptr = (uint8_t*)APP_START_ADDR + offset; FCTL3 = FWKEY; // Unlock flash FCTL1 = FWKEY covering the concept
