你好，我想了解一下，在你们做2.6.29移植uda1341声卡驱动时，改变过的和新加入都是哪些文件，我正在做2.6.28的移植 ，想做个参考。另外，mkyaffsimage工具的生成文件能不能也放出来？尝试过做yaffs的移植，但多次都没有成功啊！

新系统把这些都已经做好了，见本论坛的"FriendlyARM官方最新动态"，里面有下载地址。

没读我的帖子，请不要乱回复，烦人。

diff一下什么都看到了，脾气还不小。

UDA134x driver for S3C24x0 in Linux 2.6.29 is part of ASoc project (ALSA System On Chip, http://opensource.wolfsonmicro.com/node/6)

The main source code is located at:
sound/soc/codecs/uda134x.c             --  UDA134x codec driver
sound/soc/s3c24xx/s3c24xx-i2s.c         --  S3C24xx I2S driver
sound/soc/s3c24xx/s3c24xx_uda134x.c   -- S3C24xx based board specific configuration for UDA134x

The code needed to add to use this driver is "platform device" configuration for s3c24xx uda134x in kernel machine specific source code, e.g. following code piece in arch/arm/mach-s3c2440/mach-mini2440.c:

复制代码 static struct s3c24xx_uda134x_platform_data s3c24xx_uda134x_data = {         .l3_clk = S3C2410_GPB4,         .l3_data = S3C2410_GPB3,         .l3_mode = S3C2410_GPB2,         .model = UDA134X_UDA1341, }; static struct platform_device s3c24xx_uda134x = {         .name = "s3c24xx_uda134x",         .dev = {                 .platform_data    = &s3c24xx_uda134x_data,         } };

and add this "platform device":

复制代码 static struct platform_device *mini2440_devices[] __initdata = {         ...         &s3c24xx_uda134x, };

I suggest you take a look at Asoc project page and basic info of Linux Driver Model of 2.6 kernel before using this driver.

另外我想说明的是， 26672624说的其实并没错，作为开发者，不要总期待别人会“好心”告诉你他每一步是如何如何做的，要善于利用源代码工具，其中diff和patch命令就是最有用的工具之一。
只要你找到别人的最终成果(友善之臂提供的2.6.29的内核)和他的基础（原始的2.6.29内核源代码），它可以帮你找出别人"所做的事情"(例如，diff -Nuapr linux-2.6.29 linux-2.6.29-mini2440 > linux-2.6.29-mini2440.patch)并很容易的让你重复利用(patch -p1 < linux-2.6.29-mini2440.patch)。

ASoc S3C24xx UDA134x driver was added in 2.6.29-rc1, so you need to apply following patches manually to add this driver if you use 2.6.28 kernel. In addition, you may need to modify some of these code since they're based on 2.6.29-rc1 kernel

1. patch to add UDA134x ASoc codec driver   asoc_uda134x.patch.zip (7 K) 下载次数:77
2. patch to add S3C24xx UDA134x driver   asoc_s3c24x_uda134x.patch.zip (5 K) 下载次数:66

Usage:
1. unzip patches downloaded
2. apply patches as
$ cd /path/to/your/kernel/source/directory
$ patch -p1 < /path/to/extracted/patch/file
3. add S3C24xx UDA134x "platform device" to your machine specific file, e.g. arch/arm/mach-s3c2440/machine-smdk2440.c, as Friendly ARM does
4. re-configure your kernel properly to use this driver.

请教一下：我按照4楼所说的改的2.6.29的内核，启动信息里显示No device for dai uda134x和No device for dai s3c24xx-i2s，建立不了dsp节点，请问是什么原因，谢谢。

贴出完整的内核启动log

下面是启动信息，帮忙看一下，谢谢。
