The development of U-Boot is closely related to Linux: some parts of the source code originate in the Linux source tree, we have some header files in common, and special provision has been made to support booting of Linux images. Some attention has been paid to make this software easily configurable and extendable. For instance, all monitor commands are implemented with the same call interface, so that it's very easy to add new commands. Also, instead of permanently adding rarely used code (for instance hardware test utilities) to the monitor, you can load and run it dynamically. Status: ======= In general, all boards for which a configuration option exists in the Makefile have been tested to some extent and can be considered "working". In fact, many of them are used in production systems. In case of problems see the CHANGELOG and CREDITS files to find out who contributed the specific port. Where to get help: ================== In case you have questions about, problems with or contributions for U-Boot you should send a message to the U-Boot mailing list at . There is also an archive of previous traffic on the mailing list - please search the archive before asking FAQ's. Please see http://lists.sourceforge.net/lists/listinfo/u-boot-users/ Where we come from: =================== - start from 8xxrom sources - create PPCBoot project (http://sourceforge.net/projects/ppcboot) - clean up code - make it easier to add custom boards - make it possible to add other [PowerPC] CPUs - extend functions, especially: * Provide extended interface to Linux boot loader * S-Record download * network boot * PCMCIA / CompactFLash / ATA disk / SCSI ... boot - create ARMBoot project (http://sourceforge.net/projects/armboot) - add other CPU families (starting with ARM) - create U-Boot project (http://sourceforge.net/projects/u-boot) Names and Spelling: =================== The "official" name of this project is "Das U-Boot". The spelling "U-Boot" shall be used in all written text (documentation, comments in source files etc.). Example: This is the README file for the U-Boot project. File names etc. shall be based on the string "u-boot". Examples: include/asm-ppc/u-boot.h #include Variable names, preprocessor constants etc. shall be either based on the string "u_boot" or on "U_BOOT". Example: U_BOOT_VERSION u_boot_logo IH_OS_U_BOOT u_boot_hush_start Versioning: =========== U-Boot uses a 3 level version number containing a version, a sub-version, and a patchlevel: "U-Boot-2.34.5" means version "2", sub-version "34", and patchlevel "4". The patchlevel is used to indicate certain stages of development between released versions, i. e. officially released versions of U-Boot will always have a patchlevel of "0".

There are two classes of configuration variables: * Configuration _OPTIONS_: These are selectable by the user and have names beginning with "CONFIG_". * Configuration _SETTINGS_: These depend on the hardware etc. and should not be meddled with if you don't know what you're doing; they have names beginning with "CFG_". Later we will add a configuration tool - probably similar to or even identical to what's used for the Linux kernel. Right now, we have to do the configuration by hand, which means creating some symbolic links and editing some configuration files. We use the TQM8xxL boards as an example here. Selection of Processor Architecture and Board Type: --------------------------------------------------- For all supported boards there are ready-to-use default configurations available; just type "make _config". Example: For a TQM823L module type: cd u-boot make TQM823L_config For the Cogent platform, you need to specify the cpu type as well; e.g. "make cogent_mpc8xx_config". And also configure the cogent directory according to the instructions in cogent/README. Configuration Options: ---------------------- Configuration depends on the combination of board and CPU type; all such information is kept in a configuration file "include/configs/.h". Example: For a TQM823L module, all configuration settings are in "include/configs/TQM823L.h". Many of the options are named exactly as the corresponding Linux kernel configuration options. The intention is to make it easier to build a config tool - later. The following options need to be configured: - CPU Type: Define exactly one of PowerPC based CPUs: ------------------- CONFIG_MPC823, CONFIG_MPC850, CONFIG_MPC855, CONFIG_MPC860 or CONFIG_MPC5xx or CONFIG_MPC8220 or CONFIG_MPC824X, CONFIG_MPC8260 or CONFIG_MPC85xx or CONFIG_IOP480 or CONFIG_405GP or CONFIG_405EP or CONFIG_440 or CONFIG_MPC74xx or CONFIG_750FX ARM based CPUs: --------------- CONFIG_SA1110 CONFIG_ARM7 CONFIG_PXA250 CONFIG_CPU_MONAHANS MicroBlaze based CPUs: ---------------------- CONFIG_MICROBLAZE Nios-2 based CPUs: ---------------------- CONFIG_NIOS2 - Board Type: Define exactly one of PowerPC based boards: --------------------- CONFIG_ADCIOP CONFIG_GEN860T CONFIG_PCI405 CONFIG_ADS860 CONFIG_GENIETV CONFIG_PCIPPC2 CONFIG_AMX860 CONFIG_GTH CONFIG_PCIPPC6 CONFIG_AP1000 CONFIG_gw8260 CONFIG_pcu_e CONFIG_AR405 CONFIG_hermes CONFIG_PIP405 CONFIG_BAB7xx CONFIG_hymod CONFIG_PM826 CONFIG_c2mon CONFIG_IAD210 CONFIG_ppmc8260 CONFIG_CANBT CONFIG_ICU862 CONFIG_QS823 CONFIG_CCM CONFIG_IP860 CONFIG_QS850 CONFIG_CMI CONFIG_IPHASE4539 CONFIG_QS860T CONFIG_cogent_mpc8260 CONFIG_IVML24 CONFIG_RBC823 CONFIG_cogent_mpc8xx CONFIG_IVML24_128 CONFIG_RPXClassic CONFIG_CPCI405 CONFIG_IVML24_256 CONFIG_RPXlite CONFIG_CPCI4052 CONFIG_IVMS8 CONFIG_RPXsuper CONFIG_CPCIISER4 CONFIG_IVMS8_128 CONFIG_rsdproto CONFIG_CPU86 CONFIG_IVMS8_256 CONFIG_sacsng CONFIG_CRAYL1 CONFIG_JSE CONFIG_Sandpoint8240 CONFIG_CSB272 CONFIG_LANTEC CONFIG_Sandpoint8245 CONFIG_CU824 CONFIG_LITE5200B CONFIG_sbc8260 CONFIG_DASA_SIM CONFIG_lwmon CONFIG_sbc8560 CONFIG_DB***360 CONFIG_MBX CONFIG_SM850 CONFIG_DB***460 CONFIG_MBX860T CONFIG_SPD823TS CONFIG_DU405 CONFIG_MHPC CONFIG_STXGP3 CONFIG_DUET_ADS CONFIG_MIP405 CONFIG_SXNI855T CONFIG_EBONY CONFIG_MOUSSE CONFIG_TQM823L CONFIG_ELPPC CONFIG_MPC8260ADS CONFIG_TQM8260 CONFIG_ELPT860 CONFIG_MPC8540ADS CONFIG_TQM850L CONFIG_ep8260 CONFIG_MPC8540EVAL CONFIG_TQM855L CONFIG_ERIC CONFIG_MPC8560ADS CONFIG_TQM860L CONFIG_ESTEEM192E CONFIG_MUSENKI CONFIG_TTTech CONFIG_ETX094 CONFIG_MVS1 CONFIG_UTX8245 CONFIG_EVB***260 CONFIG_NETPHONE CONFIG_V37 CONFIG_FADS823 CONFIG_NETTA CONFIG_W7OLMC CONFIG_FADS850SAR CONFIG_NETVIA CONFIG_W7OLMG CONFIG_FADS860T CONFIG_NX823 CONFIG_WALNUT CONFIG_FLAGADM CONFIG_OCRTC CONFIG_ZPC1900 CONFIG_FPS850L CONFIG_ORSG CONFIG_ZUMA CONFIG_FPS860L CONFIG_OXC ARM based boards: ----------------- CONFIG_ARMADILLO, CONFIG_AT91RM9200DK, CONFIG_CERF250, CONFIG_CSB637, CONFIG_DELTA, CONFIG_DNP1110, CONFIG_EP7312, CONFIG_H2_OMAP1610, CONFIG_HHP_CRADLE, CONFIG_IMPA7, CONFIG_INNOVATOROMAP1510, CONFIG_INNOVATOROMAP1610, CONFIG_KB9202, CONFIG_LART, CONFIG_LPD7A400, CONFIG_LUBBOCK, CONFIG_OSK_OMAP5912, CONFIG_OMAP2420H4, CONFIG_SHANNON, CONFIG_P2_OMAP730, CONFIG_SMDK2400, CONFIG_SMDK2410, CONFIG_TRAB, CONFIG_VCMA9 MicroBlaze based boards: ------------------------ CONFIG_SUZAKU Nios-2 based boards: ------------------------ CONFIG_PCI5441 CONFIG_PK1C20 - CPU Module Type: (if CONFIG_COGENT is defined) Define exactly one of CONFIG_CMA286_60_OLD --- FIXME --- not tested yet: CONFIG_CMA286_60, CONFIG_CMA286_21, CONFIG_CMA286_60P, CONFIG_CMA287_23, CONFIG_CMA287_50 - Motherboard Type: (if CONFIG_COGENT is defined) Define exactly one of CONFIG_CMA101, CONFIG_CMA102 - Motherboard I/O Modules: (if CONFIG_COGENT is defined) Define one or more of CONFIG_CMA302 - Motherboard Options: (if CONFIG_CMA101 or CONFIG_CMA102 are defined) Define one or more of CONFIG_LCD_HEARTBEAT - update a character position on the lcd display every second with a "rotator" |\-/|\-/ - Board flavour: (if CONFIG_MPC8260ADS is defined) CONFIG_ADSTYPE Possible values are: CFG_8260ADS - original MPC8260ADS CFG_8266ADS - MPC8266ADS CFG_PQ2FADS - PQ2FADS-ZU or PQ2FADS-VR CFG_8272ADS - MPC8272ADS - MPC824X Family Member (if CONFIG_MPC824X is defined) Define exactly one of CONFIG_MPC8240, CONFIG_MPC8245 - 8xx CPU Options: (if using an MPC8xx cpu) CONFIG_8xx_GCLK_FREQ - deprecated: CPU clock if get_gclk_freq() cannot work e.g. if there is no 32KHz reference PIT/RTC clock CONFIG_8xx_OSCLK - PLL input clock (either EXTCLK or XTAL/EXTAL) - 859/866/885 CPU options: (if using a MPC859 or MPC866 or MPC885 CPU): CFG_8xx_CPUCLK_MIN CFG_8xx_CPUCLK_MAX CONFIG_8xx_CPUCLK_DEFAULT See doc/README.MPC866 CFG_MEASURE_CPUCLK Define this to measure the actual CPU clock instead of relying on the correctness of the configured values. Mostly useful for board bringup to make sure the PLL is locked at the intended frequency. Note that this requires a (stable) reference clock (32 kHz RTC clock or CFG_8XX_XIN) - Intel Monahans options: CFG_MONAHANS_RUN_MODE_OSC_RATIO Defines the Monahans run mode to oscillator ratio. Valid values are 8, 16, 24, 31. The core frequency is this value multiplied by 13 MHz. CFG_MONAHANS_TURBO_RUN_MODE_RATIO Defines the Monahans turbo mode to oscillator ratio. Valid values are 1 (default if undefined) and 2. The core frequency as calculated above is multiplied by this value. - Linux Kernel Interface: CONFIG_CLOCKS_IN_MHZ U-Boot stores all clock information in Hz internally. For binary compatibility with older Linux kernels (which expect the clocks passed in the bd_info data to be in MHz) the environment variable "clocks_in_mhz" can be defined so that U-Boot converts clock data to MHZ before passing it to the Linux kernel. When CONFIG_CLOCKS_IN_MHZ is defined, a definition of "clocks_in_mhz=1" is automatically included in the default environment. CONFIG_MEMSIZE_IN_BYTES [relevant for MIPS only] When transfering memsize parameter to linux, some versions expect it to be in bytes, others in MB. Define CONFIG_MEMSIZE_IN_BYTES to make it in bytes. CONFIG_OF_FLAT_TREE New kernel versions are expecting firmware settings to be passed using flat open firmware trees. The environment variable "disable_of", when set, disables this functionality. CONFIG_OF_FLAT_TREE_MAX_SIZE The maximum size of the constructed OF tree. OF_CPU - The proper name of the cpus node. OF_SOC - The proper name of the soc node. OF_TBCLK - The timebase frequency. OF_STDOUT_PATH - The path to the console device CONFIG_OF_HAS_BD_T The resulting flat device tree will have a copy of the bd_t. Space should be pre-allocated in the dts for the bd_t. CONFIG_OF_HAS_UBOOT_ENV The resulting flat device tree will have a copy of u-boot's environment variables CONFIG_OF_BOARD_SETUP Board code has addition modification that it wants to make to the flat device tree before handing it off to the kernel - Serial Ports: CFG_PL010_SERIAL Define this if you want support for Amba PrimeCell PL010 UARTs. CFG_PL011_SERIAL Define this if you want support for Amba PrimeCell PL011 UARTs. CONFIG_PL011_CLOCK If you have Amba PrimeCell PL011 UARTs, set this variable to the clock speed of the UARTs. CONFIG_PL01x_PORTS If you have Amba PrimeCell PL010 or PL011 UARTs on your board, define this to a list of base addresses for each (supported) port. See e.g. include/configs/versatile.h - Console Interface: Depending on board, define exactly one serial port (like CONFIG_8xx_CONS_SMC1, CONFIG_8xx_CONS_SMC2, CONFIG_8xx_CONS_SCC1, ...), or switch off the serial console by defining CONFIG_8xx_CONS_NONE Note: if CONFIG_8xx_CONS_NONE is defined, the serial port routines must be defined elsewhere (i.e. serial_init(), serial_getc(), ...) CONFIG_CFB_CONSOLE Enables console device for a color framebuffer. Needs following defines (cf. smiLynxEM, i8042, board/eltec/bab7xx) VIDEO_FB_LITTLE_ENDIAN graphic memory organisation (default big endian) VIDEO_HW_RECTFILL graphic chip supports rectangle fill (cf. smiLynxEM) VIDEO_HW_BITBLT graphic chip supports bit-blit (cf. smiLynxEM) VIDEO_VISIBLE_COLS visible pixel columns (cols=pitch) VIDEO_VISIBLE_ROWS visible pixel rows VIDEO_PIXEL_SIZE bytes per pixel VIDEO_DATA_FORMAT graphic data format (0-5, cf. cfb_console.c) VIDEO_FB_ADRS framebuffer address VIDEO_KBD_INIT_FCT keyboard int fct (i.e. i8042_kbd_init()) VIDEO_TSTC_FCT test char fct (i.e. i8042_tstc) VIDEO_GETC_FCT get char fct (i.e. i8042_getc) CONFIG_CONSOLE_CURSOR cursor drawing on/off (requires blink timer cf. i8042.c) CFG_CONSOLE_BLINK_COUNT blink interval (cf. i8042.c) CONFIG_CONSOLE_TIME display time/date info in upper right corner (requires CFG_CMD_DATE) CONFIG_VIDEO_LOGO display Linux logo in upper left corner CONFIG_VIDEO_BMP_LOGO use bmp_logo.h instead of linux_logo.h for logo. Requires CONFIG_VIDEO_LOGO CONFIG_CONSOLE_EXTRA_INFO addional board info beside the logo When CONFIG_CFB_CONSOLE is defined, video console is default i/o. Serial console can be forced with environment 'console=serial'. When CONFIG_SILENT_CONSOLE is defined, all console messages (by U-Boot and Linux!) can be silenced with the "silent" environment variable. See doc/README.silent for more information. - Console Baudrate: CONFIG_BAUDRATE - in bps Select one of the baudrates listed in CFG_BAUDRATE_TABLE, see below. CFG_BRGCLK_PRESCALE, baudrate prescale - Interrupt driven serial port input: CONFIG_SERIAL_SOFTWARE_FIFO PPC405GP only. Use an interrupt handler for receiving data on the serial port. It also enables using hardware handshake (RTS/CTS) and UART's built-in FIFO. Set the number of bytes the interrupt driven input buffer should have. Leave undefined to disable this feature, including disable the buffer and hardware handshake. - Console UART Number: CONFIG_UART1_CONSOLE AMCC PPC4xx only. If defined internal UART1 (and not UART0) is used as default U-Boot console. - Boot Delay: CONFIG_BOOTDELAY - in seconds Delay before automatically booting the default image; set to -1 to disable autoboot. See doc/README.autoboot for these options that work with CONFIG_BOOTDELAY. None are required. CONFIG_BOOT_RETRY_TIME CONFIG_BOOT_RETRY_MIN CONFIG_AUTOBOOT_KEYED CONFIG_AUTOBOOT_PROMPT CONFIG_AUTOBOOT_DELAY_STR CONFIG_AUTOBOOT_STOP_STR CONFIG_AUTOBOOT_DELAY_STR2 CONFIG_AUTOBOOT_STOP_STR2 CONFIG_ZERO_BOOTDELAY_CHECK CONFIG_RESET_TO_RETRY - Autoboot Command: CONFIG_BOOTCOMMAND Only needed when CONFIG_BOOTDELAY is enabled; define a command string that is automatically executed when no character is read on the console interface within "Boot Delay" after reset. CONFIG_BOOTARGS This can be used to pass arguments to the bootm command. The value of CONFIG_BOOTARGS goes into the environment value "bootargs". CONFIG_RAMBOOT and CONFIG_NFSBOOT The value of these goes into the environment as "ramboot" and "nfsboot" respectively, and can be used as a convenience, when switching between booting from ram and nfs. - Pre-Boot Commands: CONFIG_PREBOOT When this option is #defined, the existence of the environment variable "preboot" will be checked immediately before starting the CONFIG_BOOTDELAY countdown and/or running the auto-boot command resp. entering int ... ...
