换另一根网线2typec导网线
引导测试
上接,连线,需要安装CP2104的驱动百度下载一个

直接从emmc里驱动读取重新线程的内核参数有0x8000到1000的位置,直接运行内核,直接运行内核,最终目标应该是直接到内核和文件系统了,然后再研究下
问题
用了Ubuntu,直接的shell默认了fish,会导致smart-env.sh失败,切换成bash后无问题,当前arm架构的执行配置我没有def_config_arm,不过找了下gitee发现确实没有,没影响,的.config是arm架构的,如果想要开发其他架构的芯片,默认需要自己手动配置下配置

编译缺少工具问题
下载使用python可以通过指定python3 XXX.py来指定使用python3下载工具链,下载完成后,仍然编译不过,原因是工具链没有

编译缺少工具问题

![](//file.elecfans.com/web2/M00/50/39/poYBAGLH2YCAZFXJAACit7xAIIo029.jpg)
在使用当前目录为根深蒂固的脚本时,一定要在脚本的上,也调用目录脚本,并且设置源头就是在当前的终端环境下,所以你要使用其他环境设置变量,不会改变你导致终端的环境变量
![](//file.elecfans.com/web2/M00/50/39/poYBAGLH2YCAajxXAADdHCUbCb0272.jpg)
调整好工具链,需要重新编译makefile文件,编译完成后,第一个程序就可以编译了
DHCP问题
手头没有路由器,板卡自带的程序默认了DHCP,设置静态IP
重新编译内核需要修改
![](//file.elecfans.com/web2/M00/50/39/poYBAGLH2YCAcjTQAABTckge5ko546.jpg)
![](//file.elecfans.com/web2/M00/50/D3/pYYBAGLH2YCAFGLLAAHSEOaY8qU258.jpg)
注意不要修改.config 编译的时候应该是使用没有这个配置文件 需要修改rtconfig.h文件
重新编译内核,修改 uboot bootcmd 参数,setenv reset 完成后重启

感想
单片机了解使用RTT,对RTT的系统开发使用后,mar系列认为是在linux之前的内核上进行了比较linux的实际开发,比较linux更独立的说,RTT的环境开发的实时开发,用于开发的操作系统,于使用完成,板子的,在没有了解的下,照着当天执行了几个脚本,环境就直接完成了,APP非常简单,没有开发者监控。
接触功能性和性能方面还没有深入了解,刚刚继续更新。
