- * \page Page_SoftwareBootloaderStart Entering the Bootloader via Software
- *
- * A common requirement of many applications is the ability to jump to the programmed bootloader of a chip
- * on demand, via the code's firmware (i.e. not as a result of any physical user interaction with the
- * hardware). This might be required because the device does not have any physical user input, or simply
- * just to streamline the device upgrade process on the host PC.
- *
- * The following C code snippets may be used to enter the bootloader upon request by the user application.
- * By using the watchdog to physically reset the controller, it is ensured that all system hardware is
- * completely reset to their defaults before the bootloader is run. This is important; since bootloaders
- * are written to occupy a very limited space, they usually make assumptions about the register states based
- * on the default values after a hard-reset of the chip.
- *
- * \section Sec_SoftareBootAVR8 AVR8 Architecture
- * The following software bootloader jump code is written for the AVR8 architecture.
- *
- * \code
- * #include <avr/wdt.h>
- * #include <avr/io.h>
- * #include <util/delay.h>
- *
- * #include <LUFA/Common/Common.h>
- * #include <LUFA/Drivers/USB/USB.h>
- *
- * uint32_t Boot_Key ATTR_NO_INIT;
- *
- * #define MAGIC_BOOT_KEY 0xDC42ACCA
- * #define BOOTLOADER_START_ADDRESS (FLASH_SIZE_BYTES - BOOTLOADER_SEC_SIZE_BYTES)
- *
- * void Bootloader_Jump_Check(void) ATTR_INIT_SECTION(3);
- * void Bootloader_Jump_Check(void)
- * {
- * // If the reset source was the bootloader and the key is correct, clear it and jump to the bootloader
- * if ((MCUSR & (1 << WDRF)) && (Boot_Key == MAGIC_BOOT_KEY))
- * {
- * Boot_Key = 0;
- * ((void (*)(void))BOOTLOADER_START_ADDRESS)();
- * }
- * }
- *
- * void Jump_To_Bootloader(void)
- * {
- * // If USB is used, detach from the bus and reset it
- * USB_Disable();
- *
- * // Disable all interrupts
- * cli();
- *
- * // Wait two seconds for the USB detachment to register on the host
- * Delay_MS(2000);
- *
- * // Set the bootloader key to the magic value and force a reset
- * Boot_Key = MAGIC_BOOT_KEY;
- * wdt_enable(WDTO_250MS);
- * for (;;);
- * }
- * \endcode
- *
- * Note that the bootloader magic key can be any arbitrary value. The <em>FLASH_SIZE_BYTES</em> and
- * <em>BOOTLOADER_SEC_SIZE_BYTES</em> tokens should be replaced with the total flash size of the AVR
- * in bytes, and the allocated size of the bootloader section for the target AVR.
- *
