mini2440 256M nand版本使用uboot

1.介紹

本文中用到的uboot並非自己移植，來自Tekkaman，博客地址 ：http://blog.chinaunix.net/uid-20543672-id-94379.html，這個u-boot最初是從友善之臂論壇看到的，帖子地址 http://www.arm9home.net/read.php?tid-3539.html。

該U-boot的特性如下：

1. 同時支持S3C2410和S3C2440 （2410沒板測試）
2. 支持串口 xmodem協議 （參考www.100ask.net）
3. 支持網卡芯片 DM9000
4. 支持不同NAND Flash的讀寫,並自動識別所使用的nand flash是512B/page還是2KB/page，實現在64MB\128MB\256MB\1GB NAND flash的啟動。
5. 支持IIC接口EEPROM的操作,並可保存ENV（參考hiboy的http://www.armchina.cn/article.asp?id=70）
6. 自動識別S3C2440的啟動方式是Nor boot還是Nand boot，調用不同的自拷貝程序，實現不論是Nor boot還是Nand boot，都可以燒寫同一個bin文件。(nor flash為SST39VF1601)
7. 支持燒寫yaffs/yaffs2文件系統映象.
8. 添加支持讀取SD卡中的FAT32文件系統，現在U-boot已經支持從U盤或SD卡上啟動。
9. 添加支持OpenOCD導入內存啟動，其實就是在一切flash識別之前，檢測自己是否在內存，如果已在內存就跳過自拷貝程序。
10. 支持NEC 3.5寸LCD輸出console信息和BMP圖片、logo。（參考openmoko）
11. 支持使用DNW工具，通過USB device口進行文件傳輸。（參考了 hugerat.cublog.cn 和 Apollo5520.cublog.cn 兩個高手的移植）

2.獲取移植好的源碼

Tekkaman將u-boot for mini2440命名為了u-boot-2010.03-tekkaman，其github主頁為 https://github.com/tekkamanninja/u-boot-2010.03-tekkaman

我們可以采用以下兩種方式獲取到該源碼；

1.執行git clone git://github.com/tekkamanninja/u-boot-2010.03-tekkaman.git

2.點擊github主頁的ZIP圖標，將其源碼打包為zip壓縮包下載到本地。如下圖所示

兩種方式均可，根據個人情況選擇，如果Linux下能聯網的話，建議使用第一種方式。

3.編譯u-boot.bin

作者在其 http://blog.chinaunix.net/uid-20543672-id-94379.html中已經提供了編譯好的u-boot.bin下載；不想自己編譯的，可坐享其成。

     NOTE：下載后得到的文件名為100418215118.bz2，務必改名為u-boot.bin.tar.bz2之后，再進行解壓，原因？了解下tar包和bz2壓縮格式的關系吧。

下面介紹如何自己編譯，來得到一個u-boot.bin。請確認交叉編譯器arm-linux-gcc已經正確安裝，本文編譯u-boot使用的是開發板光盤提供的4.4.3版本。

$ git clone git://github.com/tekkamanninja/u-boot-2010.03-tekkaman.git

$ cd u-boot-2010.03-tekkaman

$ make ARCH=arm CROSS_COMPILE=arm-linux- mini2440_config

$ make ARCH=arm CROSS_COMPILE=arm-linux- all

注意，arm-linux-和mini2440_config以及arm-linux-和all之間各有一個空格。執行完這兩條命令，當前目錄下就會產生一個名為u-boot.bin個文件。這就是我們要燒寫到開發板上的二進制文件了。如下圖所示：

...

4.燒寫到開發板

mini2440開發板默認已經帶有supervivi，我們可以借助supervivi里的 [a] Absolute User Application選項，通過 DNW下載到NAND Flash中。

5.測試

燒寫完成之后，開發板斷電，切換到Nand啟動，開發板上電，正常的話，開發板蜂鳴器會有大約1秒的聲響，串口終端會有信息打印出來，如果此時無任何操作，uboot會根據事前做好的配置引導內核，啟動開發板。

Tekkaman已經將uboot的默認啟動方式改為了網絡啟動，因此此時是無法引導內核的。啟動過程如下所示：

開發板此時會停留在Loading這里，每個一段時間打印一個T，每隔一段時間嘗試連接一次服務器。經過30次嘗試之后，會重啟網絡服務，再次嘗試連接。如下圖所示：

如果想進入U-boot的命令界面，怎麽辦呢？系統上電，做完必要的初始化工作之后，會有1秒的時間給用戶來選擇是否進入U-boot的命令界面。如下圖所示：

當U-boot執行這里的時候，按鍵盤的任意鍵，可使U-boot進入命令模式，而不會去引導內核。這個時間只有1秒，很短，因此如有必要，可在開發板剛上電的時候就開始按鍵。U-boot進入命令行之后如下所示：

輸入help，可以查看U-boot支持的命令以及各自的作用，自測去吧。關於U-boot的使用方法，本文不過多涉及，請自己查閱資料。

6.設置Uboot，使Uboot能引導nand flash里的Kernel

在mini2440中，由於u-boot.bin文件大小已經大於了0x40000，所以作者修改了ENV的 OFFSET。現在的Nand分區是這樣的：

uboot地址范圍是0x0-0x60000，共384KB
uboot參數區地址范圍是0x60000-0x80000，共128KB
kernel地址范圍是0x80000-0x500000，共5MB

在include/configs/mini2440.h中有nand分區的定義：

而在Supervivi中bootloader是0x0-0x40000，params是0x40000-0x60000，kernel是0x60000-0x500000；

如果u-boot是用supervivi的k選項將linux kernel傳到nand flash的。那么，Kernel的地址就會和u-boot中的params沖突，導致U-boot無法引導內核。

解決辦法:

修改linux kernel中對Nand的分區定義，使其與u-boot保持一致。kernel的nand分區信息在arch/arm/mach-s3c2440/mach-mini2440.c中的名為friendly_arm_default_nand_part的結構體數組里。

如下圖所示，為默認情況下，kernel中對Nand分區的定義：

根據U-boot的nand分區配置，我們需要將其修改為如下所示：

回到Kernel根目錄，執行make zImage命令，會重新生成/arch/arm/boot/zImage。現在又有一個問題：uboot目前只能支持uImage啟動，不支持zImage啟動，因此我們需要使用mkimage工具把zImage轉換為uImage；我們可以通過兩種方式獲取到mkimage工具：

1. uboot源碼根目錄下的tools目錄下
2. 執行以下命令安裝

# apt-get install uboot-mkimage

uImage是在zImage之前加上一個長度為0x40字節（64字節）的頭部，來說明zImage這個映像文件的映象名、映像類型、加載地址、入口地址、生成時間、大小等信息。換句話說，如果直接從uImage的0x40位置開始執行，zImage和uImage沒有任何區別。U-boot引導內核是通過bootm完成的，bootm加載uImage的時候，會先對uImage進行解壓（去掉0x40字節的頭部），解壓地址為內核入口地址（由mkimage的-e選項指定）。當解壓完成時的uImage跟原zImage是完全相同的。

轉換zImage為uImage的命令如下所示：

mkimage -n "linux-2.6.32.2" -A arm -O Linux -T kernel -C none -a 0x30008000 -e 0x30008040 -d zImage uImage

執行mkimage --help可以查看mkimage的幫助信息；

其中，

-A用於指定平台架構，我們的是arm平台

-O用於指定操作系統，我們的是Linux操作系統

-T用於指定映像類型，映像是內核鏡像，指定為Kernel

-C用於指定壓縮類型，此處我們不壓縮，設為none

-a用於指定夾在地址，0x30008000

-e用於指定入口地址，uImage去除0x40字節的頭部信息之后，即為zImage，這便是kernel的入口地址，指定為0x30008040

-d用於指定data文件，從內容上看，zImage不含格式信息，就是一個普通的數據文件，因此此處指的就是zImage

uImage即為輸出文件名。

接下來我們通過生成的uImage文件與zImage做一下對比：

$ file uImage zImage 
uImage: u-boot/PPCBoot image
zImage: data
備注：從格式上來看，uImage為u-boot啟動映像文件；zImage為普通的數據文件；
$ ls -l uImage zImage
-rw-r--r-- 1 gyl gyl 2266644 2013-05-12 17:45 uImage
-rwxr-xr-x 1 gyl gyl 2266580 2013-05-12 17:45 zImage
備注：文件大小正好差64字節；

$ mkimage -l uImage

備注：查看uImage的頭部信息；

u-boot能引導的內核已經制作好了，接下來我們測試一下能否正常工作；

首先，從nandflash重啟開發板，進入u-boot命令界面，依次執行以下幾條命令：

• 執行usbslave 1 0x30008000  #通過usb線將uImage下載至內存0x30008000中(在主機上執行dnw...)
• 執行nand erase 0x80000 0x500000  #擦除此區域，nand使用之前需要先擦除，以便接下來將linux kernel保存到這個地址處。
• 執行nand write 0x30008000 0x80000 0x500000  #從內存的0x30008000地址處開始拷貝0x500000字節的內容到nandflash的0x80000地址處。
• 修改u-boot引導參數

setenv bootcmd 'nand read 0x30008000 0x80000 0x500000;bootm 0x30008000'

setenv bootargs 'noinitrd root=/dev/mtdblock3 initrd=/linuxrc console=ttySAC0'

saveenv

• 重啟開發板

從nand啟動u-boot然后引導內核啟動，並且掛載根文件系統的全過程如下所示：
