淘了一个a20行车记录仪主板,并编译lichee

偶然间在淘宝上发现了20块钱的a20行车记录仪的主板,
淘宝链接:https://item.taobao.com/item.htm?spm=a230r.1.14.91.6de65a756h4Fsi&id=594462933314&ns=1&abbucket=8#detail
到手后发现运行camdroid,通过bootlogo来看是凌度的机子,

先将bananapi的官方系统写入,成功启动,但是无法使用usb,
bananian系统下载地址:
https://mirrors.tuna.tsinghua.edu.cn/bananian/releases/bananian-latest.zip

从原系统无法获取到scripts.bin,
于是就想编译a20的lichee来使用usb。
全志官方下载地址:http://dl.linux-sunxi.org/SDK/A20-SDK-2.0/aw.tar.bz2
有5个G,但是真正使用的是里面的lichee-2.0.tar.gz,
但是在github上找到了相应项目,https://github.com/dwlinux/Armcore_a20_V30_lichee

参考晕哥的这篇教程:https://whycan.cn/t_1522.html

注意,一定要使用ubuntu-14.04,不然的话遇到的坑是无法填的,
首先安装依赖

sudo apt-get install -y libncurses-dev lib32z1 lib32ncurses5 lib32stdc++6 u-boot-tools make g++ gettext python unzip fakeroot bison texinfo bc flex gcc-arm-linux-gnueabi gcc-arm-linux-gnueabihf
cd /opt
git clone --depth=1 https://github.com/dwlinux/Armcore_a20_V30_lichee

这里可以将github.com换成github.com.cnpmjs.org提高克隆速度。

然后直接编译就行了

cd Armcore_a20_V30_lichee
./build.sh -m all

其中会遇到几个坑,
1.host-m4-1.4.15

In file includedfrom clean-temp.h:22:0,
from clean-temp.c:23:
./stdio.h:456:1:error: 'gets' undeclared here (not in a function)

对host-m4-1.4.15/lib/stdio.in.h文件根据补丁内容自行修改

根据这个补丁文件修改即可,直接修改源代码包,下次编译就不会再提示这个错误了。

3.host-makedevs

      ^

直接修改/opt/Armcore_a20_V30_lichee/out/linux/common/buildroot/build/host-makedevs/makedevs.c文件:
最后一行,return 0;
修改为:return ret;

我给板子上换了一个8GB的nand flash,所以去内核里面勾选nand flash的驱动后再编译

最后打包,选择sun7i_linux_evb-v10

./build.sh pack

最后打包好的文件在tools/pack/sun7i_linux_evb-v10.img

使用PhoenixSuit烧录,要提前进入fel模式,可以通过烧录fel-boot.sunxi到sd卡来进入,

wget http://www.hno.se/code/A10/OLD/fel-boot.sunxi
dd if=fel-boot.sunxi of=/dev/sdX bs=1024 seek=8

Re: 淘了一个a20行车记录仪主板,并编译lichee

巧了,我前段时间也在折腾这块板子,最后用了点“奇技淫巧”把script.bin导出来了: https://whycan.com/t_5343.html
如果有人需要我可以上传一下转换过后的fex。
另外从fex内容中看不出板子上8脚的fpc母座和空焊的无线模块焊盘连接的GPIO(fex没有gpio_para段)。目前我想到的最简单的方法就是把SoC吹下来然后挨个脚测,或者在gpio_vx里顺序把每个引脚拉高一次然后测电平,但可能是因为之前配置的方式不对或没选对引脚,没能测到电平变化。
这个板子疑似是全志的公版方案,我找到了一篇疑似其软件方案的文档:

https://wenku.baidu.com/view/5dd3cba8195f312b3069a548.html
国庆这段时间又去折腾另一张四块五的Mstar的行车记录仪板子了,那个自带系统是RTOS,前两天编译了一个疑似可用的镜像。之后有时间还要接着折腾这个A20的板子
