TMS320F280049C: 关于LFU历程使用的问题

//! This example demonstrates how to perform a live firmware update with use
//! of the Live Device Firmware Update (Live DFU or LDFU) command. The LDFU 
//! command is supported in Serial Flash Programmer which communicates with 
//! the SCI Flash Kernel.
//!
//! In the example, an SCI autobaud lock is performed and the byte used for autobaud
//! lock is echoed back. Two interrupts are initialized and enabled: SCI Rx FIFO
//! interrupt and CPU Timer 0 interrupt. The CPU Timer 0 interrupt occurs every 1
//! second; the interrupt service routine (ISR) for CPU Timer 0 toggles an LED
//! based on the build configuration that is running. LED1 is toggled for the
//! BANK0_FLASH and BANK0_ROM build configurations and LED2 is toggled for the
//! BANK1_FLASH and BANK1_ROM build configuration. The SCI Rx FIFO interrupt is set
//! for a FIFO interrupt level of 10 bytes. The number of bytes in a packet from the
//! Serial Flash Programmer (when using the LDFU command) is 10. When a command is
//! sent to the device from the Serial Flash Programmer, the SCI Rx FIFO ISR receives
//! a command from the 10 byte packet in the FIFO. If the command matches the Live
//! Device Firmware Update (Live DFU) command, then the code branches to the Live DFU
//! function located inside of the SCI Flash Kernel for the corresponding bank.
//!
//! The project contains 2 build configurations:
//!     - BANK0_FLASH: Links the program sections to the appropriate locations
//!                    in Bank 0 of flash and uses the Flash API library that
//!                    links the Flash API functions to flash. The 'codestart'
//!                    section is linked to the alternative flash entry point
//!                    for Bank 0 (0x8EFF0) and the rest of the sections are
//!                    linked to 0x082008 or above. Bank 0 configurations of
//!                    the flash kernel reserve sector 0, sector 1, and the
//!                    first 128 bits of sector 2 of Bank 0; therefore, sections
//!                    must be linked to 0x082008 or higher. After building the
//!                    configuration, the C2000 Hex Utility will output the
//!                    program in the appropriate SCI boot hex format for the
//!                    flash kernel and serial flash programmer in a file named
//!                    'flashapi_ex2_liveFirmwareUpdateBANK0FLASH.txt'.
//!
//!     - BANK1_FLASH: Links the program sections to the appropriate locations
//!                    in Bank 1 of flash and uses the Flash API library that
//!                    links the Flash API functions to flash. The 'codestart'
//!                    section is linked to the alternative flash entry point
//!                    for Bank 1 (0x9EFF0) and the rest of the sections are
//!                    linked to 0x092008 or above. Bank 1 configurations of
//!                    the flash kernel reserve sector 0, sector 1, and the
//!                    first 128 bits of sector 2 of Bank 1; therefore,
//!                    sections must be linked to 0x092008 or higher. After
//!                    building the configuration, the C2000 Hex Utility will
//!                    output the program in the appropriate SCI boot hex format
//!                    for the flash kernel and serial flash programmer in a
//!                    file named 'flashapi_ex2_liveFirmwareUpdateBANK1FLASH.txt'.

//! \b External \b Connections \n
//!  - Connect GPIO28 (SCI Rx) and GPIO29 (SCI Tx) to a COM port of the computer
//!    running the Serial Flash Programmer project. In control card this is 
//!    routed via the USB port. So juct connecting the USB cable to PC will 
//!    suffice.
