            幾種Bootloader簡(jiǎn)介

            Posted on 2007-10-06 19:24 謝龍飛 閱讀(1993) 評(píng)論(2)  編輯 收藏 引用
             Redboot

            RedbootRedhat公司隨eCos發(fā)布的一個(gè)BOOT方案,是一個(gè)開源項(xiàng)目。

            當(dāng)前Redboot的最新版本是Redboot-2.0.1Redhat公司將會(huì)繼續(xù)支持該項(xiàng)目,其官方發(fā)布網(wǎng)址為:http://sources.redhat.com/redboot/。

            Redboot支持的處理器構(gòu)架有ARM,MIPS,MN10300PowerPC, Renesas SHx,v850,x86等,是一個(gè)完善的嵌入式系統(tǒng)Boot Loader。

            Redboot是在ECOS的基礎(chǔ)上剝離出來(lái)的,繼承了ECOS的簡(jiǎn)潔、輕巧、可靈活配置、穩(wěn)定可靠等品質(zhì)優(yōu)點(diǎn)。它可以使用X-modemY-modem協(xié)議經(jīng)由串口下載,也可以經(jīng)由以太網(wǎng)口通過(guò)BOOTP/DHCP服務(wù)獲得IP參數(shù),使用TFTP方式下載程序映像文件,常用于調(diào)試支持和系統(tǒng)初始化(Flash下載更新和網(wǎng)絡(luò)啟動(dòng))。Redboot可以通過(guò)串口和以太網(wǎng)口與GDB進(jìn)行通信,調(diào)試應(yīng)用程序,甚至能中斷被GDB運(yùn)行的應(yīng)用程序。Redboot為管理FLASH映像,映像下載,Redboot配置以及其他如串口、以太網(wǎng)口提供了一個(gè)交互式命令行接口,自動(dòng)啟動(dòng)后,REDBOOT用來(lái)從TFTP服務(wù)器或者從Flash下載映像文件加載系統(tǒng)的引導(dǎo)腳本文件保存在Flash上。當(dāng)前支持單板機(jī)的移植版特性有:

            -          支持ECOSLinux操作系統(tǒng)引導(dǎo)

            -          在線讀寫Flash

            -          支持串行口kermit,S-record下載代碼

            -          監(jiān)控(minitor)命令集:讀寫I/O,內(nèi)存,寄存器、 內(nèi)存、外設(shè)測(cè)試功能等

            Redboot是標(biāo)準(zhǔn)的嵌入式調(diào)試和引導(dǎo)解決方案,支持幾乎所有的處理器構(gòu)架以及大量的外圍硬件接口,并且還在不斷地完善過(guò)程中。

             

            l         ARMboot

            ARMboot是一個(gè)ARM平臺(tái)的開源固件項(xiàng)目,它特別基于PPCBoot,一個(gè)為PowerPC平臺(tái)上的系統(tǒng)提供類似功能的姊妹項(xiàng)目。鑒于對(duì)PPCBoot的嚴(yán)重依賴性,已經(jīng)與PPCBoot項(xiàng)目合并,新的項(xiàng)目為U-Boot。

            ARMboot發(fā)布的最后版本為ARMboot-1.1.0,2002ARMboot終止了維護(hù),其發(fā)布網(wǎng)址為:http://sourceforge.net/projects/armboot。

            ARMboot支持的處理器構(gòu)架有StrongARM ,ARM720T ,PXA250 等,是為基于ARM或者StrongARM CPU的嵌入式系統(tǒng)所設(shè)計(jì)的。

            ARMboot的目標(biāo)是成為通用的、容易使用和移植的引導(dǎo)程序,非常輕便地運(yùn)用于新的平臺(tái)上。ARMbootGPL下的ARM固件項(xiàng)目中唯一支持Flash閃存,BOOTPDHCP、TFTP網(wǎng)絡(luò)下載,PCMCLA尋線機(jī)等多種類型來(lái)引導(dǎo)系統(tǒng)的。特性為:

            -          支持多種類型的FLASH

            -          允許映像文件經(jīng)由BOOTPDHCP、TFTP從網(wǎng)絡(luò)傳輸;

            -          支持串行口下載S-record或者binary文件

            -          允許內(nèi)存的顯示及修改

            -          支持jffs2文件系統(tǒng)等

            Armboot對(duì)S3C44B0板的移植相對(duì)簡(jiǎn)單,在經(jīng)過(guò)刪減完整代碼中的一部分后,僅僅需要完成初始化、串口收發(fā)數(shù)據(jù)、啟動(dòng)計(jì)數(shù)器和FLASH操作等步驟,就可以下載引導(dǎo)uClinux內(nèi)核完成板上系統(tǒng)的加載??偟脕?lái)說(shuō),ARMboot介于大、小型Boot Loader之間,相對(duì)輕便,基本功能完備,缺點(diǎn)是缺乏后續(xù)支持。

             

            l         U-Boot

            U-Boot是由開源項(xiàng)目PPCBoot發(fā)展起來(lái)的,ARMboot并入了PPCBoot,和其他一些archLoader合稱U-Boot。20021217日第一個(gè)版本U-Boot-0.2.0發(fā)布,同時(shí)PPCBootARMboot停止維護(hù)。

            U-Boot自發(fā)布以后已更新6,最新版本為U-Boot-1.1.1U-Boot的支持是持續(xù)性的。其發(fā)布網(wǎng)址為:http://sourceforge.net/projects/u-boot/。

            U-Boot支持的處理器構(gòu)架包括PowerPC (MPC5xx,MPC8xxMPC82xxMPC7xx,MPC74xx,4xx) ARM ARM7,ARM9,StrongARMXscale),MIPS (4Kc,5Kc),x86等等, U-BootUniversal Bootloader從名字就可以看出,它是在GPL下資源代碼最完整的一個(gè)通用Boot Loader。

            U-Boot提供兩種操作模式:啟動(dòng)加載(Boot loading)模式和下載(Downloading)模式,并具有大型Boot Loader的全部功能。主要特性為:

            -          SCC/FEC以太網(wǎng)支持 

            -          BOOTP/TFTP引導(dǎo) 

            -          IP,MAC預(yù)置功能 

            -          在線讀寫FLASH,DOC, IDEIIC,EEROM,RTC

            -          支持串行口kermit,S-record下載代碼 

            -          識(shí)別二進(jìn)制、ELF32、pImage格式的Image,對(duì)Linux引導(dǎo)有特別的支持 

            -          監(jiān)控(minitor)命令集:讀寫I/O,內(nèi)存,寄存器、內(nèi)存、外設(shè)測(cè)試功能等

            -          腳本語(yǔ)言支持(類似BASH腳本)

            -          支持WatchDog,LCD logo,狀態(tài)指示功能等 

            U-Boot的功能是如此之強(qiáng)大,涵蓋了絕大部分處理器構(gòu)架,提供大量外設(shè)驅(qū)動(dòng),支持多個(gè)文件系統(tǒng),附帶調(diào)試、腳本、引導(dǎo)等工具,特別支持Linux,為板級(jí)移植做了大量的工作。U-Boot1.1.1版本特別包含了對(duì)SA110044B0芯片的移植,所以44B0移植主要是針對(duì)Board 的移植,包括FLASH、內(nèi)存配置以及串口波特率等等。U-Boot的完整功能性和后續(xù)不斷的支持,使系統(tǒng)的升級(jí)維護(hù)變得十分方便。

             

            l         Blob

            Blob(Boot Loader Object)是由Jan-Derk Bakker and Erik Mouw發(fā)布的,是專門為StrongARM 構(gòu)架下的LART設(shè)計(jì)的Boot Loader。

            Blob的最后版本是blob-2.0.5,其發(fā)布網(wǎng)址為:http://www.lart.tudelft.nl/lartware/blob/。

            Blob支持SA1100LART主板,但用戶也可以自行修改移植。

            Blob也提供兩種工作模式,在啟動(dòng)時(shí)處于正常的啟動(dòng)加載模式,但是它會(huì)延時(shí) 10 秒等待終端用戶按下任意鍵而將 Blob 切換到下載模式。如果在 10 秒內(nèi)沒(méi)有用戶按鍵,則 Blob 繼續(xù)啟動(dòng) Linux 內(nèi)核。其基本功能為:

            初始化硬件(CPU速度,存儲(chǔ)器,中斷,RS232串口)

            -          引導(dǎo)Linux內(nèi)核并提供ramdisk

            -          LART下載一個(gè)內(nèi)核或者ramdisk

            -          FLASH片更新內(nèi)核或者ramdisk

            -          測(cè)定存儲(chǔ)配置并通知內(nèi)核

            -          給內(nèi)核提供一個(gè)命令行

            Blob功能比較齊全,代碼較少,比較適合做修改移植,用來(lái)引導(dǎo)Liunx,目前大部分S3C44B0板都用Blob修改移植后來(lái)加載uClinux。 

            l         Bios-lt

            Bios-lt是專門支持三星(Samsung)公司ARM構(gòu)架處理器S3C4510BLoader,可以設(shè)置CPU/ROM/SDRAM/EXTIO,管理并燒寫FLASH,裝載引導(dǎo)uClinux內(nèi)核。這是國(guó)內(nèi)工程師申請(qǐng)GNU通用公共許可發(fā)布的。                  

            Bios-lt的最新版本是Bios-lt-0.74,另外還提供了S3C4510B的一些外圍驅(qū)動(dòng),其發(fā)布網(wǎng)址為:http://sourceforge.net/projects/bios-lt

            l         Bootldr

            Bootldr是康柏(Compaq)公司發(fā)布的,類似于compaq iPAQ Pocket PC,支持SA1100芯片。它被推薦用來(lái)引導(dǎo)Llinux,支持串口Y-modem協(xié)議以及jffs文件系統(tǒng)。                                          

            Bootldr的最后版本為Bootldr-2.19,其發(fā)布網(wǎng)址為: http://www.wearablegroup.org/software/bootldr/

             ViVi

                    vivi是什么?

                    vivi是由mizi公司設(shè)計(jì)為ARM處理器系列設(shè)計(jì)的一個(gè)bootloader,因?yàn)関ivi目前只支持使用串口和主機(jī)通信,所以您必須使用一條串口電纜來(lái)連接目標(biāo)板和主機(jī)。

                   它有如下作用:

                   1)、 把內(nèi)核(kernel)從flash復(fù)制到RAM,然后啟動(dòng)它

                   2)、 初始化硬件

                   3)、 下載程序并寫入flash(一般通過(guò)串口或者網(wǎng)口先把內(nèi)核下載到RAM中,然后寫入到flash)

                   4)、 檢測(cè)目標(biāo)板(bootloader會(huì)有一些簡(jiǎn)單的代碼用以測(cè)試目標(biāo)板硬件的好壞)

                   vivi的使用方法

                   摘錄自vivi的guide.txt,稍作修改。

            2. vivi 的編譯

            This section describes how to compile the vivi.

            2.1. Pre-Requirements

            Here is a list of the minimum levels of software necessary to compile the vivi.

             

            * Gnu C 2.95.3

             

            * Gnu make 3.79.1

             

            * binutils 2.11.2

             

            And then, your host platform are installed these tools.

             

            * You have a cross-compiler and tool-chains.

             

            * You have a Baurne-Again shell. (/bin/bash)

             

            * You have a ncurses library.

            2.2. Straight-forward compilation

            The compiliation(configuration) environment of the vivi is simlilar to the environment of the linux kernel. So, you can do make distclean, make clean, make oldconfig , make menuconfig, and make config. General compiling sequence sequence is:

             

            1) make distclean

             

            2) make menuconfig

             

            3) make

             

            Note that If you change configurations, run make clean and make. Next two sections describes compilation of two examples.

            2.3. SA-1110-Based machines with the NOR flash

            I will take an example about the vivi compliation. I assumed that a target platform's core block is composed like this:

             

            * CPU: SA-1110 processor

             

            * ROM: 32MB Intel Strata Flash (32-bit wide)

             

            * RAM: 32MB DRAM

             

            These features make sense to you. Many platforms I have met is designed core block like above. For instance, KINGS, GILL, and ENDA's core block is designed like this. Therefore, you refer to vivi/arch/def-configs/kings, vivi/arch/def-configs/gill, and vivi/arch/def-configs/enda

             

            If you want to compile vivi for KINGS(i.e. a configuration of a target board, alredy exist in the vivi/arch/def-cofnigs), just do like this:

             

            # make kings

             

            Other machines can complie same ways.

            2.4. S3C2410-Based machines with the NAND flash

            Here, I will take an example about a S3C2410-Based machine. The SMDK-2410 (a development board by SAMSUNG) is a S3C2410-Based machine.The core block of SMDK-2410 is composed like this:

             

            * CPU: S3C2410

            * ROM: 64MB SMC (NAND Flash)

            * RAM: 64MB DRAM

             

            A configuration for SMDK-2410 will be found atvivi/arch/def-configs/smdk2410. To compile for SMDK-2410, do like this(As I described above):

             

            # make smdk2410

            3. vivi的使用

            3.1. Interface between an user and the vivi

            The vivi uses the serical communication for user interface. Therefore, to connect the vivi, you

            1) connect a serial cable between host platform and target platform.

            2) already have a serial communication program like the minicom.

            3) properly make the vivi binary to support a UART port when you configure the vivi.

             

            If all of above is ok, you can see messages on the screen printed by the vivi. For example, below messages catched from the SMDK-2410

             

            VIVI version 0.1.4 (nandy@nandy.mizi.com) (gcc version 2.95.2 20000516 (release)

             

            [Rebel.com]) #0.1.4 10 16 16:19:11 KST 2002

             

            MMU table base address = 0x33DFC000

             

            Succeed memory mapping.

            NAND device: Manufacture ID: 0xec, Chip ID: 0x75 (Samsung KM29U256T)

            Found saved vivi parameters.

             

            Press Return to start the LINUX now, any other key for vivi

             

            See the last line on the screen. (As I mentioned section 1.1) the vivi has two mode: an autoboot mode and a prompt mode. The vivi wait for a key input. If an user want to enter the prompt mode, press andy key (except Enter key). And then you can see the "vivi>" prompt. Otherwise, the vivi try boot the linux kernel after waiting a few seconds or minutes.

            3.2. Built-in user commands

            This is not full-described built-in user comamnd. But following commands is enough to use the vivi (as far as I know).

            3.2.1. load command

            A load command is loading binaries to the flash or the ram.

             

            Usage:

             

            load [ | ]

             

            This argument is where to load. Availabe values are *flash* and *ram*.

             

            [ ] or [ ]

             

            This arguement determines location where to load a binary. If you want to use pre-defined mtd partiton informations, just type a partition name. Otherwise you specify an address and a size.

             

            This arguement determines the file transfer protocol. I shy that the vivi only supprot xmodem curruntly. So, Available value is "x".

             

            For exampe, you load zImage to flash memroy.

             

            vivi > load flash kernel x

             

            or you specify an address and a size.

             

            vivi > load flash 0x80000 0xc0000 x

            3.2.2. part command

            The vivi has mtd partiton informations for the vivi. This informatin not related to mtd partition informations of mtd device drivers. The vivi uses partition informations when load a binary, boot the linux kernel, erase flash memroy, etc...

             

            Avalilable commands are:

             

            Display mtd partition informations.

             

            part show

             

            Add a new mtd partition.

             

            part add

             

            is name of a new mtd partiton.

            is offset in the mtd device.

            is a size of a mtd parition.

            is flags of a mtd parition. Available valuse are JFFS2, LOCKED, and BONFS.

             

            Delete a mtd partiton.

             

            part del

             

            Reset mtd partitions to default values.

             

            part reset

             

            Save paramter valuse and mtd parition informations to flash permanently.

             

            part save

            3.2.3. param command

            The vivi has some parameter values. For example, the "boot_delay" paramter determines how long wait keystroke when the vivi is in the autoboot mode. I'm sorry that this feature is in progress. So all listed parameter is not available.

             

            Here, I give several tips for you.

             

            If you change the "linxu command line",

             

            vivi> param set linux_cmd_line "you wish.."

             

            If you want to see paramters,

             

            vivi> param show

             

            If you want to wait a long time when recevie file via xmodem,

             

            vivi> param set xmodem_initial_timeout 3000000

             

            If you want to boot imediately when a hardware reset,

             

            vivi> param set boot_delay 100000

            3.2.4. boot command

            A boot command is boot the linux kernel which is stored in the flashmemroy or ram.

             

            Usage:

             

            boot [ | ]

             

            This argument is where to store the linux kernel image. Availabe values are ram, nor and smc.

             

            [ ] or [ ]

             

            This arguement determines location where to store the linux kernel. If you want to use pre-defined mtd partiton information, just type a partition name. Otherwise you shuld specify an address and a size.

             

            Note that all argument is optional. If you omit all argument (just type boot), all arguments is parsing from pre-defined mtd parititon information called "kernel" For example,

             

            vivi> boot

             

            the vivi read the linux kernel binary from the "kernel" mtd parititons.

             

            vivi> boot nor 0x80000

             

            the vivi read the linux kernel binary form the nor flash memory. The offset is 0x80000 and the size is default value (0xc0000). Ocassionally, you want to test the kernel on the ram (not store kernel to flash). you can do it on the vivi On the SA-1110 based machine,

             

            vivi> load ram 0xc0008000 x

             

            vivi> boot ram

             

            On the S3C2410 based machine,

             

            vivi> load ram 0x30008000 x

             

            vivi> boot ram

             

            On the PXA-240 based machine,

             

            vivi> load ram 0xA0008000 x

             

            vivi> boot ram

             

            the vivi boot the linux kernel from the ram.

            3.2.5. flash command

            A flash comamnd manages the flash memory. If you want to erase flash memory,

             

            flash erase [ | ]
