我的Linux入坑日记,顺便求解其中的问题。

刚入坑,但感觉到处是坑。 mad

写驱动代码,说要内核源码,准备内核源码去了。

驱动编译发现不通过,说是要先编译内核源码,就先编译内核源码。

其中遇到各种编译问题,交叉编译问题,gcc版本过高问题。

完了终于编译得到 .ko 文件,拉去开发板说版本不对,无法加载,完蛋

查了半天,说可以改个头文件,改完 modinfo 后的确和开发板一样了,但还是提示加载失败

以上

最后决定从 uboot-->内核--->根文件系统 开始整个流程走一遍,心想,这下版本对了吧。

然后编译uboot遇到各种错误,很久很久才解决

然后编译内核遇到各种错误,很久很久才解决,甚至重装了 ubuntu 两次 。。。。。

最后编译根文件,又是各种错误。。。。

以上,都是根据教程来的,为啥自己就那么多错误,是官方给的东西玩我还是人品问题,这条路走不通。。。。

最后 uboot 烧录成功了,串口输出又是一堆错误,忽略!

然后拷贝镜像、设备树、根文件系统那个压缩文件解压

万事俱备,启动-------》

结果没有看到应该有的打印信息  reading zImage
反而设备树给打印出来了。。。。。

说是环境变量问题,看着也有 load mmc 0:1 0x41000000 zImage
没毛病啊。。。。

不信邪,再来几遍,再去搜

终于,既然环境变量没问题,我直接执行uboot指令可以吧
于是直接执行了  load mmc 0:1 0x41000000 zImage

好家伙,真的打印 reading zImage

然后执行 bootz 0x41000000 - 0x41800000,尝试进入Linux系统!

结果又打脸,显示根文件无法加载!

我感觉Linux就是个大坑。

楼主这是高手必经之路啊,是不是没设置 bootargs 的 root 参数,linux没找到根文件系统。

查了一下,你说的应该是“ root=/dev/mmcblk0p2 ”

分区时,32M/FAT16、剩余空间/EXT4

这是uboot的环境变量:

Re: 我的Linux入坑日记,顺便求解其中的问题。

其实Linux还好,感觉主要是嵌入式这一块坑比较多

再加上是全志的东西,资料少之又少,坑不多才怪呢 big_smile

这段错误我也注意到了,但是并不知道该如何更改环境变量。

我以为 ttyS0,115200=panic=5 rootwait root=/dev/mmcblk0p2 就是该部分选项

网上搜索得知,有可能是内核不接受uboot的参数导致的:

Re: 我的Linux入坑日记,顺便求解其中的问题。

查看Linux内核配置:

Boot options --->
     Kernel command line type (Use bootloader kernel arguments if available)  --->   

这说明使用的就是Uboot的参数,但是貌似无法获取

Re: 我的Linux入坑日记,顺便求解其中的问题。

自己瞎搞,根据网上的配置,修改了环境变量

来源: https://blog.csdn.net/xxxx123041/article/details/119938816

setenv bootargs 'console=ttyS0,115200 panic=5 rootwait root=/dev/mmcblk0p2 earlyprintk rw  vt.global_cursor_default=0'
setenv bootcmd 'mmc dev 0;fatload mmc 0:1 0x41000000 zImage;fatload mmc 0:1 0x41800000 sun8i-v3s-licheepi-zero.dtb;bootz 0x41000000 - 0x41800000;'
saveenv
boot

最后打印

可以看到最后打印得超级慢,也不知道是什么原因导致的

但是但是但是但是但是但是但是但是但是但是但是但是

成功了!

输入 cd /
输入 ls

看到了久违的文件列表打印
