34 * \brief Flash boot loader main.
35 * This is a simple generic bootloader app.
36 * It requires only a serial port to work.
37 * Try to receive a file through XMODEM protocol
38 * and flash it on program memory.
39 * BOOT_INIT, BOOT_END are macros used to perform special operations
40 * respectively at boot start and boot end and are CPU dependant.
41 * The macro START_APP() jumps to main application start.
