If you wish to alter this size and/or change the AVR model, you will need to - * edit the MCU, FLASH_SIZE_KB and BOOT_SECTION_SIZE_KB values in the accompanying makefile. - * - * When the bootloader is running, the board's LED(s) will flash at regular intervals to distinguish the - * bootloader from the normal user application. - * - * \section Sec_Running Running the Bootloader - * - * This bootloader is designed to be started via the HWB mechanism of the USB AVRs; ground the HWB pin (see device - * datasheet) then momentarily ground /RESET to start the bootloader. This assumes the HWBE fuse is set and the BOOTRST - * fuse is cleared. - * - * \section Sec_Installation Driver Installation - * - * This bootloader uses the Generic Text-Only printer drivers inbuilt into all modern operating systems, thus no - * additional drivers need to be supplied for correct operation. - * - * \section Sec_HostApp Host Controller Application - * - * This bootloader is compatible with Notepad under Windows, and the command line \c lpr utility under Linux. - * - * \subsection SSec_Notepad Notepad (Windows) - * - * While most text applications under Windows will be compatible with the bootloader, the inbuilt Notepad utility - * is recommended as it will introduce minimal formatting changes to the output stream. To program with Notepad, - * open the target HEX file and print it to the Generic Text Only printer device the bootloader creates. - * - * \subsection SSec_LPR LPR (Linux) - * - * While the CUPS framework under Linux will enumerate the bootloader as a Generic Text-Only printer, many - * applications will refuse to print to the device due to the lack of rich formatting options available. As a result, - * under Linux HEX files must be printed via the low level \c lpr utility instead. - * - * \code - * cat Mouse.hex | lpr - * \endcode - * - * \section Sec_API User Application API - * - * Several user application functions for FLASH and other special memory area manipulations are exposed by the bootloader, - * allowing the user application to call into the bootloader at runtime to read and write FLASH data. - * - * By default, the bootloader API jump table is located 32 bytes from the end of the device's FLASH memory, and follows the - * following layout: - * - * \code - * #define BOOTLOADER_API_TABLE_SIZE 32 - * #define BOOTLOADER_API_TABLE_START ((FLASHEND + 1UL) - BOOTLOADER_API_TABLE_SIZE) - * #define BOOTLOADER_API_CALL(Index) (void*)((BOOTLOADER_API_TABLE_START + (Index * 2)) / 2) - * - * void (*BootloaderAPI_ErasePage)(uint32_t Address) = BOOTLOADER_API_CALL(0); - * void (*BootloaderAPI_WritePage)(uint32_t Address) = BOOTLOADER_API_CALL(1); - * void (*BootloaderAPI_FillWord)(uint32_t Address, uint16_t Word) = BOOTLOADER_API_CALL(2); - * uint8_t (*BootloaderAPI_ReadSignature)(uint16_t Address) = BOOTLOADER_API_CALL(3); - * uint8_t (*BootloaderAPI_ReadFuse)(uint16_t Address) = BOOTLOADER_API_CALL(4); - * uint8_t (*BootloaderAPI_ReadLock)(void) = BOOTLOADER_API_CALL(5); - * void (*BootloaderAPI_WriteLock)(uint8_t LockBits) = BOOTLOADER_API_CALL(6); - * - * #define BOOTLOADER_MAGIC_SIGNATURE_START (BOOTLOADER_API_TABLE_START + (BOOTLOADER_API_TABLE_SIZE - 2)) - * #define BOOTLOADER_MAGIC_SIGNATURE 0xDCFB - * - * #define BOOTLOADER_CLASS_SIGNATURE_START (BOOTLOADER_API_TABLE_START + (BOOTLOADER_API_TABLE_SIZE - 4)) - * #define BOOTLOADER_PRINTER_SIGNATURE 0xDF20 - * - * #define BOOTLOADER_ADDRESS_START (BOOTLOADER_API_TABLE_START + (BOOTLOADER_API_TABLE_SIZE - 8)) - * #define BOOTLOADER_ADDRESS_LENGTH 4 - * \endcode - * - * From the application the API support of the bootloader can be detected by reading the FLASH memory bytes located at address - * \c BOOTLOADER_MAGIC_SIGNATURE_START and comparing them to the value \c BOOTLOADER_MAGIC_SIGNATURE. The class of bootloader - * can be determined by reading the FLASH memory bytes located at address \c BOOTLOADER_CLASS_SIGNATURE_START and comparing them - * to the value \c BOOTLOADER_PRINTER_SIGNATURE. The start address of the bootloader can be retrieved by reading the bytes of FLASH - * memory starting from address \c BOOTLOADER_ADDRESS_START. - * - * \subsection SSec_API_MemLayout Device Memory Map - * The following illustration indicates the final memory map of the device when loaded with the bootloader. - * - * \verbatim - * +----------------------------+ 0x0000 - * | | - * | | - * | | - * | | - * | | - * | | - * | | - * | | - * | User Application | - * | | - * | | - * | | - * | | - * | | - * | | - * | | - * +----------------------------+ FLASHEND - BOOT_SECTION_SIZE - * | | - * | Bootloader Application | - * | (Not User App. Accessible) | - * | | - * +----------------------------+ FLASHEND - 96 - * | API Table Trampolines | - * | (Not User App. Accessible) | - * +----------------------------+ FLASHEND - 32 - * | Bootloader API Table | - * | (User App. Accessible) | - * +----------------------------+ FLASHEND - 8 - * | Bootloader ID Constants | - * | (User App. Accessible) | - * +----------------------------+ FLASHEND - * \endverbatim - * - * - * \section Sec_KnownIssues Known Issues: - * - * \par On Linux machines, new firmware fails to be sent to the device via CUPS. - * Only a limited subset of normal printer functionality is exposed via the - * bootloader, causing CUPS to reject print requests from applications that - * are unable to handle true plain-text printing. For best results, the low - * level \c lpr command should be used to print new firmware to the bootloader. - * - * \par After loading an application, it is not run automatically on startup. - * Some USB AVR boards ship with the BOOTRST fuse set, causing the bootloader - * to run automatically when the device is reset. In most cases, the BOOTRST - * fuse should be disabled and the HWBE fuse used instead to run the bootloader - * when needed. - * - * \section Sec_Options Project Options - * - * The following defines can be found in this demo, which can control the demo behaviour when defined, or changed in value. - * - * <table> - * <tr> - * <td> - * None - * </td> - * </tr> - * </table> - */ - |
