Uboot_for_Tiny6410_移植步驟詳解

一、           設計要求

1.        目的

1)        掌握U-boot剪裁編寫

2)        掌握交叉編譯環境的配置

3)        掌握U-boot的移植

2.        實現的功能

1)        U-boot編譯成功

2)        移植U-boot，使系統支持從NAND  FLASH啓動

二、           設計方案

1.        硬件資源

1)        ARM處理器：ARM11芯片(Samsung S3C6410A)，基於 ARM1176JZF-S核設計，運行頻率 533Mhz,  最高可達 667Mhz

2)        存儲器： 128M DDR RAM，可升級至 256M；MLC NAND Flash(2GB)

3)        其他資源：具有三LCD接口、 4線電阻觸摸屏接口、100M 標準網絡接口、標準DB9 五線串口、Mini USB 2.0 接口、USB Host 1.1、3.5mm音頻輸入輸出口、標準TV-OUT 接口、SD卡座、紅外接收等常用接口；另外還引出4路TTL串口，另 1 路 TV-OUT、SDIO2 接口(可接SD WiFi)接口等；在板的還有蜂鳴器、I2C-EEPROM、備份電池、AD可調電阻、8 箇中斷式按鍵等。

2.        軟件資源

1)        arm-linux-gcc-4.5.1（交叉編譯）

2)        u-boot-2010.09.tar.gz  arm-linux-gcc-4.5.1-v6-vfp-20101103.tgz

三、           移植過程

1.      環境搭建

1)        建立交叉編譯環境

2)        下載得到最新或者你想要的u-boot。

下面是具體的對u-boot…的修改

 

一： 下載並解壓u-boot-gxb.tar.gz。

       #tar xzvf u-boot-gxb.tar.gz

二：在頂層的目錄下找到Makefile文件，並用gedit打開

在Makefile中找到下面代碼進行修改

ulong     get_PCI_freq (void);

#endif

#if defined(CONFIG_S3C24X0) || \

    defined(CONFIG_LH7A40X) || \

    defined(CONFIG_S3C6400) || \

    defined(CONFIG_S3C6410) || \     添加紅色的

    defined(CONFIG_EP93XX)

ulong     get_FCLK (void);

ulong     get_HCLK (void);

ulong     get_PCLK (void);

 

ulong     get_UCLK (void);

#endif

十四：修改頂層的MAKEALL

Unknown / orphaned boards:

十六：修改   nand_spl/board/samsung/ tiny6410/config.mk

                                             下面的這個沒有改動

# FriendlyARM TINY6410 development board,based on

# Samsung S3C64xx Reference Platform (smdk6400) board

 

# TEXT_BASE for SPL:

#

# On S3C64xx platforms the SPL is located in SRAM at 0.

#

# TEXT_BASE = 0

 

include $(TOPDIR)/board/$(BOARDDIR)/config.mk

 

# PAD_TO used to generate a 4kByte binary needed for the combined image

# -> PAD_TO = TEXT_BASE + 4096

PAD_TO := $(shell expr $(TEXT_BASE) + 4096)

 

ifeq ($(debug),1)

PLATFORM_CPPFLAGS += -DDEBUG

Endif

十七：在nand_sql/board/Samsung/tiny6410 這個tiny6410是仿照上述smdk6410做的內容一樣複製然後修改下面的就   OK

Nand_sql/board/Samsung/tiny6410/Makefile

# from board directory

#=========================更改部分===================================

$(obj)lowlevel_init.S:

       @rm -f $@

#     @ln -s $(TOPDIR)/board/samsung/smdk6400/lowlevel_init.S $@

   @ln -s $(TOPDIR)/board/samsung/tiny6410/lowlevel_init.S $@

#=================================================================
