昨天刚拿到RK3288-Reload的开发板，今天正好有时间就来折腾下。
目前的任务是:
以前做了一块FPGA的板子，能够与一块音频编解码的芯片通过I2S做到音频数据流的传输，现在的想法是直接用RK3288的板子来替换音频编码芯片，直接通过I2S总线进行录音。
总体计划:
因为对这个板子不太熟悉，预计一个星期时间，中间可能会遇到一些问题，希望大家多多指教，同时也希望这份记录能为后来人带来点参考。
目前已经给板子上电了，并且切换到了Ubuntu系统＾＿＾
内核和版本都是板子自带的
:lol折腾起来吧~

折腾起来吧~
不错，写一个系列的教程！

不错，写一个系列的教程！
教程谈不上，只是个记录，还希望各路大神过来指教
OK，继续安装Toolchain，我把下载下来的文件解压复制到了/opt/Firefly文件夹下面：
现在添加进环境变量中:
vim ~/.bashrc
我比较喜欢这种方式添加环境变量
129行那个 $ARM_LINUX是以前玩其他开发板的时候添加的，可以省略
再执行下 source ~/.bashrc 让环境变量生效
设置好后的效果如下:
说明安装成功了
继续来编译内核
现在内核根目录执行下make firefly-rk3288-linux_defconfig
看下默认的配置，如下:
看到使用的是ALSA音频系统，SoC的音频支持已经加入了ESP8323的支持
比较疑惑的是，在ES8323的下面，还有一个ES8323 for PCM modem，
不知道什么意思，求指教!
还有昨天耳机插上不能用，最后查出来ES8323驱动加载正常，只是和HDMI的声音有冲突。
插上HDMI线时，默认使用HDMI播放声音，再插入耳机，耳机也就没有反应了。
这个应该是个bug吧～
怎么见不到开发的人，不来论坛交流嘛（⊙＿⊙）？
编译:
masong@hydra:~/Coding/learnUbuntu/firefly-rk3288-kernel$ make ARCH=arm CROSS_COMPILE=arm-eabi- -j8 firefly-rk3288.img
最后出现这样就说明编译成功了
OBJCOPY arch/arm/boot/zImage
Kernel: arch/arm/boot/zImage is ready
Image: kernel.img is ready
Pack to resource.img successed!
Image: resource.img (with firefly-rk3288.dtb logo.bmp) is ready
你提出的es8323问题，我们会去跟进的。

感觉es8323启动中间异常了，有没有firefly的开发过来看下~
8323的驱动是android和ubuntu内核共用，create file失败是因为ubuntu没有/data目录，可以在probe中把路径改一下
zouxf 发表于 2016-4-18 09:59
ES8323 和 HDMI 是两个声卡，如果你要验证ES8323是否正常，可以使用aplay来播放wav文件测试。
可以验证es8323驱动是正常的，只是插上HDMI的线，会优先使用HDMI播放声音，当去除掉HDMI线时，耳机声音就正常了。
感觉音频es8323这块的问题好大
昨天查看的启动信息补全，完全的是这样的
