Description: 基于linux kernel 2.6.20的UDA1341声音芯片的声卡驱动，在s3c2410 cpu下调试通过。
使用方法:源码树的根下新建local目录，并将其解压缩到该目录，修改源码树根下的Makefile文件的559行为：
vmlinux-dirs := $(patsubst ％/,％,$(filter ％/, $(init-y) $(init-m) $(core-y) $(core-m) $(drivers-y) $(drivers-m) $(net-y) $(net-m) $(libs-y) $(libs-m))) local/
就可以编译了，不过是模块编译，编译好了之后不要忘了insmod进内核啊-Linux kernel 2.6.20 based on the sound chip UDA1341 sound card driver in the adoption of s3c2410 cpu debugging. Usage: source tree root under the new local directory, and unzip to that directory, edit the Makefile under the root source file 559 acts: vmlinux-dirs: = $ (patsubst /,,$( filter /, $ (init-y) $ (init-m) $ (core-y) $ (core-m) $ (drivers-y) $ (drivers-m) $ (net-y) $ (net- m) $ (libs-y) $ (libs-m))) local/can be compiled, but is a module compiler, the compiler better not forget that after the insmod into the kernel ah Platform: |

Description: 这个驱动的移植主要是是将原来的2..4.18内核中的1341驱动程序直接往2.6.11上移植的，没有采用ALSA。移植过程中也曾经参考过一些资料，具体是哪位大虾的资料忘记了，在此感谢文中所参考的资料的大虾们
硬件环境：SBC-2410X开发板（CPU：S3C2410X）
内核版本：2.6.11.1
运行环境：Debian2.6.8
交叉编译环境：gcc-3.3.4-glibc-2.3.3
第一部分 声卡UDA1341TS驱动程序播放部分的移植
一、从网上将Linux内核源代码下载到本机上，并将其解压：
#tar jxf linux-2.6.11.1.tar.bz2
二、打开内核顶层目录中的Makefile文件，这个文件中需要修改的内容包括以下两个方面。
-This was mainly driven transplantation is the original 2 .. 4.18 kernel drivers 1341 directly to the Transplant 2.6.11, and did not use ALSA. Transplantation process have also made reference to some information, specific information prawns who have forgotten, would like to thank the paper for reference information on the hardware environment of shrimp are: SBC-2410X development board (CPU: S3C2410X) kernel version: 2.6.11.1 Operating Environment: Debian2.6.8 cross compiler environment: gcc-3.3.4-glibc-2.3.3 the first part of the sound card driver UDA1341TS play one part of the transplant, from the Internet Linux kernel source code will be downloaded to the machine, and decompression:# tar jxf linux-2.6.11.1.tar.bz2 Second, open the core top-level Makefile in the directory file, the document need to modify the contents include the following two aspects.
