porting u-boot to QQ2440V3

I've ported an u-boot with basic function to QQ2440v3. It is based on openmoko u-boot (http://svn.openmoko.org/trunk/src/target/u-boot/patches).

I'll commit the all patches to opencsbc project (http://opencsbc.svn.sourceforge.net/viewvc/opencsbc/) later.

Comments welcome :)

请不要再要我发build的步骤到邮箱了，我已经贴出来了，在帖子的第二页

不客气，不过再好的代码躺在SVN里面是没有用的，只有实际用了才能体现价值

u-boot-1.3.1中qq2440.h中的在NANDFLASH中设定环境变量的地址空间时

#define CFG_ENV_OFFSET 是怎么定义的？需要考虑哪些因素？你设定的CFG_ENV_SIZE 是 16k

#define  CFG_ENV_OFFSET_00B 1 的定义，没有替代CFG_ENV_OFFSET 的意思呀？
.......

CFG_ENV_OFFSET_OOB的意思是把env数据分区的offset写在block 0的OOB区域里，至于这个offset如何用的，恐怕你的看代码才能了解。
这个机制的可以参考 http://wiki.openmoko.org/wiki/NAND_bad_blocks#Environment

请问版主能把u-boot -1.3.1 for  QQ2440V3的源码发给我吗 我现在正在研究这  万分感谢    邮箱 wxlllove@126.com

我已经把u-boot patch check in到https://opencsbc.svn.sourceforge.net/svnroot/opencsbc/trunk/target/u-boot/patches
你可以通过下面的命令check out:
svn co https://opencsbc.svn.sourceforge.net/svnroot/opencsbc opencsbc

有关svn的操作参考https://sourceforge.net/svn/?group_id=204028
有关build u-boot的步骤我已经发Mail到你的邮箱

已发

我更新过u-boot的patch,大概没法在原来版本的u-boot上用了,现在应该在u-boot 1.3.2-rc2上可以

Here's the instructions for how to build u-boot for FriendlyARM QQ2440V3:

You'll need svn(subrevision, http://subversion.tigris.org/) and quilt tool (http://savannah.nongnu.org/projects/quilt) installed on the development PC

1. Install Cross Compile Toolchain from Pokylinux.org

$wget http://pokylinux.org/releases/pinky-3.1/poky-eabi-glibc-i686-arm-toolchain-pinky-3.1.tar.bz2

$tar jxvf poky-eabi-glibc-i686-arm-toolchain-pinky-3.1.tar.bz2 -C /

2. Get u-boot source code against which the QQ2440 patches are generated:

Get u-boot soruce tar ball from U-boot project FTP:
$wget ftp://ftp.denx.de/pub/u-boot/u-boot-1.3.2-rc1.tar.bz2


$tar jxvf u-boot-1.3.2-rc1.tar.bz2

3. Get QQ2440 u-boot patch from opencsbc via svn
$svn co https://opencsbc.svn.sourceforge.net/svnroot/opencsbc opencsbc

4. patch u-boot with opencsbc patch for QQ2440

$cd u-boot-1.3.2-rc1 && cp -a ../opencsbc/trunk/target/u-boot/patches . && quilt push -av

5. build u-boot for QQ2440
$make ARCH=arm \
CROSS_COMPILE=/usr/local/poky/eabi-glibc/arm/bin/arm-poky-linux-gnueabi- \
qq2440_config

$make ARCH=arm \
CROSS_COMPILE=/usr/local/poky/eabi-glibc/arm/bin/arm-poky-linux-gnueabi- \
all

You'll get u-boot.bin after it is complied successfully

6. Flash the generated u-boot.bin into NAND Flash by SJF jtag tool on Windows

7. You'll get u-boot running on QQ2440 after reset the board

Note:
1. The u-boot contains LCD support for the 7" 800x480
LCD only currently
2. This u-boot porting is based on the one by
OpenMoko, for general features on this u-boot, see
http://wiki.openmoko.org/wiki/U-boot

你可以把'$'后面的命令直接复制粘贴到bash命令提示符后面执行

我不是已经贴出来了吗？

It depends on which s3c24x0 frame buffer driver you use. In this case, I use framebuffer driver from openmoko and add 7' LCD configuration to board/qq2440/qq2440.c like following:


+#ifdef CONFIG_VIDEO
+void board_video_init(GraphicDevice *pGD)
+{
+    S3C24X0_LCD * const lcd = S3C24X0_GetBase_LCD();
+
+    /* FIXME: select LCM type by env variable */
+
+    /* Configuration for GTA01 LCM on QT2410 */
+#ifdef QQ2440_LCD_TFT_800480
+        /* Configuration for HITACHI 7" LCM on QQ2440 */
+        lcd->LCDCON1 = 0x00000178;
+        lcd->LCDCON2 = 0x1977c141;
+        lcd->LCDCON3 = 0x021b1f28;
+        lcd->LCDCON4 = 0x00000d1f;
+        lcd->LCDCON5 = 0x00000b08;
+        lcd->LPCSEL  = 0x00000f82;
+
+        pGD->winSizeX = pGD->plnSizeX = 800;
+        pGD->winSizeY = pGD->plnSizeY = 480;
+        pGD->gdfBytesPP = 2;
+        pGD->gdfIndex = GDF_16BIT_565RGB;
+
+        pGD->frameAdrs = LCD_VIDEO_ADDR;
+        pGD->memSize = 0xBB800; /* 800*480*16bit  */
+
+#elif defined QQ2440_LCD_TFT_240320
+#error "NEC 3.5' LCD on QQ2440 not supported yet"
+#endif
+}
+#endif
