@零度灬救赎目前2.4G最高，不支持再超到更高频率。强行超频可能会导致CPU物理损坏。建议增加散热措施，让CPU持续工作在高频即可。

Welcome to OpenEmbedded, the build framework for embedded Linux. OpenEmbedded offers a best-in-class cross-compile environment. It allows developers to create a complete Linux Distribution for embedded systems. Some of the OpenEmbedded advantages include:

adopted as the build system for the Yocto Project in March 2011.

support for many hardware architectures

multiple releases for those architectures

tools for speeding up the process of recreating the base after changes have been made

easy to customize

runs on any Linux distribution

cross-compiles 1000's of packages including GTK+, Qt, the X Windows system, Mono, Java, and about anything else you might ever need

step1:
git clone https://gitee.com/yanyitech/openwrt.git cd openwrt ### Quickstart 1. Run `./scripts/feeds update -a` to obtain all the latest package definitions defined in feeds.conf / feeds.conf.default 2. Run `./scripts/feeds install -a` to install symlinks for all obtained packages into package/feeds/ 3. Run `make menuconfig` to select your preferred configuration for the toolchain, target system & firmware packages. 4. Run `make` to build your firmware. This will download all sources, build the cross-compile toolchain and then cross-compile the GNU/Linux kernel & all chosen applications for your target system.

@wuming 按照如下方法操作，格式化EMMC
1.按住中间的loader按键同时短按复位按键，机器就会进入maskrom模式，如下图所示：

2.选择loader文件，选择EMMC，点击download，等待完成以后点击Eraseall。即可完成EMMC擦除。

@大法师 said in Coolpi 4b support dynamic update logo:

Sometimes we may need to customize the logo display. We just need to copy logo bmp files to first partition of tf-card or emmc. Two logo files can be the same.

It should be noted that uboot must be upgraded to the latest.

@jugg 如下图所示，电脑的line out输出经过衰减以后接入COOLPI耳机座的MIC输入端。正常麦克风的电平范围控制到20mv以内。所以电阻参数根据电脑line out输出的信号幅度决定。
