linux-xc · Cortex M0/M3/M4/M7

SD卡：
32GB
FAT32
扇区512byte

MCU:
STM32F103C8T6

SD卡与MCU连接方式：SPI

移植FatFs前：
能够初始化SD卡，能够写入/读出，正常。

移植FatFs后：
无法挂载（提示未格式化FR_NO_FILESYSTEM）
挂载成功时，始终无法使用 open、read、write 等函数（提示FR_DISK_ERR）

官方版本：FatFs R0.14b

打印等级如下：

root@LicheePi:/# cat /proc/sys/kernel/printk
7       4       1       7

但在驱动模块不论是多高等级的信息，都打印在了dmesg去了

很不巧，又是自己解决了。

发现应用程序所访问的设备文件差了一个字母。。。。。

然后用read/write正常了

但是，使用 cat 和 echo 还是会有问题，我想应该是后面学到的东西才能解决。

使用dmesg发现，使用echo写入内容后，会不断打印收到的数据，像是write不断被执行。

使用了两次 cat 打开，dmesg打印如下：

找到办法了，完全查看内核配置的各个选项后，发现内核配置没有勾选USB的网络相关驱动。
不知道官方为什么没有默认选择这部分驱动？

因此，我直接将所有相关驱动都加载进去了
应该是某个驱动实现了，但暂时并不清楚，有待前辈指点。

具体方法，在内核源码目录输入 make ARCH=arm menuconfig

Device Drivers  --->  
    [*] Network device support  ---> 
         <*>   USB Network Adapters  --->
                子选项全部勾选,子选项的子选项默认即可

此外，还可以自行搜索以下配置打勾（根据自身需要打勾）（按键盘 / 键可以搜索）

DNS Resolver support

Generic failover module

Network block device support

USB CATC NetMate-based Ethernet device support

烧录网友提供的.dd镜像可以找到usb0设备，联网，但是自己重新编译的内核更换原来的内核后，就无法找到usb0了。

dmesg打印表明无法加载autofs4、ipv6模块，应该是找不到usb0导致的

以下的ifconfig打印信息：

但是经过以上操作，并不能ping通，已经确保OTG链接到路由器，能上网

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

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

看日志，确实没有设置 root 参数

网上搜索得知，有可能是内核不接受uboot的参数导致的：

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

因为是单片机过渡来的，想玩Linux，就从最简单的荔枝派开始，以为会有个好开始。。。。

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

哇酷小二说：

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

刚入坑，但感觉到处是坑。

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。

@哇酷小二

感谢回答，的确是bootcmd脚本问题，但我好奇的是官方给的配置为什么不加入启动内核的脚本？

我在uboot命令行输入以下两条指令成功引导镜像：

=> <INTERRUPT>
=> load mmc 0:1 0x41000000 zImage
reading zImage
3860984 bytes read in 633 ms (5.8 MiB/s)
=> bootz 0x41000000 - 0x41800000

这个脚本应该在那里固化?
最后我将跟文件系统的结果解压到了SD卡上，但Linux内核最后提示无法加载跟文件系统。

2 file(s), 0 dir(s)

已经烧录uboot
已经将 zimage、sun8i-v3s-licheepi-zero.dtb拷贝到FAT16主分区
未拷贝根文件系统

前辈们，这是需要烧录跟文件系统才可以自动加载Linux吗？
已经看到uboot读取了设备树。

找到了部分解决办法，来自网上：

最后打印信息如下:

小白虽然不知道为何，但看打印信息vga，应该是关于屏幕的问题，没有接入屏幕导致的？
但是后面的驱动依然没有解决

根据官方办法编译成功得到：u-boot-sunxi-with-spl.bin
并烧录：if=u-boot-sunxi-with-spl.bin of=/dev/sdb1 bs=1024 seek=8

方法来源：http://zero.lichee.pro/%E7%B3%BB%E7%BB%9F%E5%BC%80%E5%8F%91/uboot_build.html

最后启动荔枝派，但是串口打印各种错误信息，是否正常？如何解决?我还没烧录Linux

已自行解决。
问题的原因是Ubuntu 安装了多个版本的arm-linux-gnueabihf，手动卸载/删除关于arm-linux-gnueabihf的文件后重新安装即可

linux-xc · 全志 SOC

根据荔枝派zero文档要求：
安装交叉编译器：gcc-linaro-6.3.1-2017.05-x86_64_arm-linux-gnueabihf
下载Linux源码： git clone https://github.com/Lichee-Pi/linux.git
下载的是 4.10.y 版本。
