在2410内核的基础上移植2.6内核的步骤

最后进行内核编译。


#make


然后将镜像下载到开发板中去，启动信息如下：

可以看到UDA1341 audio driver initialized的信息，说明声卡已经初始化。进入终端之后，查看设备文件名：


[root@fa /]# ls -al /dev/sound/*

crw-------    1 root     root      14,   3 Jan  1 00:00 /dev/sound/dsp

crw-------    1 root     root      14,   0 Jan  1 00:00 /dev/sound/mixer

由此可见，声卡已经成功驱动，要测试驱动程序可以用cat 命令（如：cat  ALSNDMGR.WAV > dev/sound/dsp），也可以用madplay播放mp3文件。










第二部分     声卡UDA1341TS驱动程序播放部分的移植


    1、UDA1341TS录音调试记录
修改sound/oss/s3c2410-uda1341.c 文件中的audio_init_dam函数
对应于dma_ch=1的情况
s3c2410_dma_config(s->dma_ch,2,0xa2900000);原来为0xa0900000(设置DCON寄存器，对应位［26：24］)，查看S3C2410数据手册(8-10)中的对应位定义，DCON1［26：24］应为010(I2SSDI)、而原来设置为000（UART1）


2、测试：
（1）、从网上http://www.eca.cx/ecasound/download.php下载ecasound-2.4.3.tar.gz
（2）、tar zxf ecasound-2.4.3.tar.gz
（3）、cd ecasound-2.4.3
（4）、配置：
CC=/opt/crosstool/gcc-3.3.4-glibc-2.3.3/arm-s3c2410-linux-gnu/bin/arm-s3c2410-linux-gnu-gcc CXX=/opt/crosstool/gcc-3.3.4-glibc-2.3.3/arm-s3c2410-linux-gnu/bin/arm-s3c2410-linux-gnu-g++ ./configure --enable-all-static --disable-ncurses --host=arm-s3c2410-linux-gnu  --target=arm-s3c2410-linux-gnu --prefix=/friendly-arm/rootfs_netserv/usr/local
（5）、编译
make
（6）、安装
sudo make install
（7）、cd /friemdly-arm/rootfs_netserv/usr/local/bin
（8）、./ecasound -i:/dev/sound/dsp -o /tmp/somefile.wav -c
