SD card boot and flashing tool for TI davinic DM368

實驗環境：

DM368 平臺 : LW3xx

SD card : Micro SD 128MB

HOST : ubuntu 10.04.4 64-bit

CROSS_COMPILE : CodeSourcery GNU Toolchain for ARM Processors: 2009q1-203 version

1，參考網址

http://processors.wiki.ti.com/index.php/SD_card_boot_and_flashing_tool_for_DM355_and_DM365

http://wiki.linpert.de/index.php?title=LeopardBoard/SD_CARD

2，下載 SD boot 工具 dm3xx_sd_boot

3，解壓 dm3xx_sd_boot-6.1.tgz，並重新編譯

#export PATH=$PATH:/opt/arm-2009.q1-203/bin
#make clean
#make CROSSCOMPILE=arm-none-linux-gnueabi-

編譯時有錯誤發生，解決方法請參考http://wiki.linpert.de/index.php?title=LeopardBoard/SD_CARD

DM36x/debug.o:(.ARM.exidx+0x0): undefined reference to `__aeabi_unwind_cpp_pr1'

修改 sdcard_flash/Makefile，增加下面一行就可以解決問題（記得要重新 make clean & make）

CFLAGS+= -mabi=aapcs-linux

4，在 dm3xx_sd_boot-6.1/original 目錄準備好適用於 LW3xx 平臺的 UBL, u-boot, uImage 二進制文件，並修改文件 dm3xx_sd.config 

DM36x)
    ubl=original/ubl_DM36x_ARM432_DDR340_OSC24_NAND.bin
    uboot=original/u-boot-2011.12.bin
    kernel=original/uImage-3.3.4
    ;;

注意：UBL 要選用 NAND 版本的 

編譯 LW3xx UBL 請參考《TI davinci DM368 UBL 編譯方法》

編譯 LW3xx uboot 請參考《TI davinci DM368 u-boot 編譯方法》

編譯 LW3xx uImage 請參考《編譯 davinci linux 的方法》

5，插入 SD 卡，並格式化 SD 卡

根據提示，重新插拔 SD 卡

6，將 ubl, u-boot... 寫到 SD 卡中

#make install

此處有一個錯誤 "ERROR: overlapping at 60000 (ftell = 6b228)"

這是由於 u-boot 太大了，已經覆蓋到了 uImage 的分區，解決方法如下：

首先，修改 sdcard_flash/sdboot_flash_cfg.h

第31行

#define UBOOT_SIZE (160*KB) 修改爲 #define UBOOT_SIZE (512*KB)

第42行

#define KERNEL_SDC 0x060000 修改爲 #define KERNEL_SDC 0x080000

其次，修改 dm3xx_sd_boot-6.1/Makefile

第3行

arch=$(shell uname  -m | sed -e "s/i.86.*/x86/" -e "s/arm.*/arm/" -e "s/x86.*/x86/")

第23行 

rm -f $(BIN)/dm3xx_boot_make_image

最後執行

#make
#make CROSSCOMPILE=arm-none-linux-gnueabi-
#make install

7，將 SD 卡插入 LW3xx SD卡槽，然後設置 LW3xx 爲從 SDMMC 啓動（LW3xx 平臺是 R428 接 3.3v）

8，LW3xx 上電後，即可以看到如下信息：

1 - boot; 2 - install; 3 - erase flash, 4 - nand boot, 5 - test first 16MB of RAM
u - install ubl only, d - nand flash dump

9，選擇 2 - install，就可以把 UBL, u-boot, uImage ... 下載到 NAND flash 中

10，再斷電，設置 LW3xx 爲從 NAND 啓動（LW3xx 平臺是 R428 接地），重新上電即從 NAND 啓動了
