思路我这里大概有了,我先自己摸索摸索去。

我之所以要用linux的模块方式来搞,就是为了让荔枝派发挥他最大的价值:带我入门真正意义的嵌入式驱动开发领域。

纯c写,我知道怎么搞,那个简单。

目前找到了这篇文章,看的稀里糊涂,主要是荔枝派nano上烧写的linux,里面也没gcc呀
难道说需要我在ubuntu上编译好,然后往荔枝派nano的设备树上挂载?

用了两天时间,终于一步一步的从uboot烧录,到linux编译烧录,到根文件烧录,系统跑起来了。我这里也记录了整个过程,方便大家:
https://www.cnblogs.com/scy251147/p/14856721.html
https://www.cnblogs.com/scy251147/p/14858574.html

目前已经成功进入系统。
现在有个问题,怎么利用嵌入式linux开发的方式来点亮一个led等。
我说的嵌入式开发的方式,是指按照如下方式:

module_init(led_init);
module_exit(led_exit);
MODULE_LICENSE("GPL");

其中module_init和module_exit都是linux定义好的模块初始化和模块卸载的操作,我们只需要实现其中的具体逻辑,和arduino目前的开发模式有点像。

请问各位大佬,这个该如何开始?

把文件系统重做一个

嗯。看来确实是根文件系统问题,换一个rootfs.tar就可以了,后面我会用目前这个交叉编译链重新打包个。现在准备开个新帖,来问另一个问题,嵌入式开发的问题。

怎么确认较差编译使用的EABI接口呢?

上面链接里面有


arm-linux-gcc -v


哦哦,好的,sorry, 我傻了, 问了个白菜问题。

我看我的.config中配置:
CONFIG_AEABI=y
CONFIG_OABI_COMPAT=y

这俩应该都是生效了。看上去应该还有别的选项干扰。

uboot正常了,第一分区放了zimage和dtb文件,第二分区放了根文件系统,但是启动报错
是不是根文件系统有问题?有大佬遇到过吗?

@哇酷小二
sd卡的话,我用了如下的命令了:

sudo mkdir /mnt/sdb2   //创建一个临时目录
sudo mount /dev/sdb2 /mnt/sdb2  //将sdb2挂载到此临时目录
sudo cp rootfs.tar /mnt/sdb2  //拷贝到sdb2中,此时sdb2中已经能看到跟文件
sudo tar -xf rootfs.tar  进入目录并解压
sudo rm rootfs.tar  //删掉tar
sudo sync
sudo umount /dev/sdb2

想问问各位,上面的uboot引导是不是有问题呀?

哇酷小二 说:

前面那個是對的, 后面那个只有 spl (boot0), 没有 u-boot

请问下,生成的 dtb文件 在 dts同级目录下,将其放入 TF卡第一分区。这里的命令是不是:
sudo cp suniv-f1c100s-licheepi-nano.dtb /dev/sdb1

好的,谢谢解答,我按照前面那个烧写试试

论坛里面有一篇帖子,提到了烧写应该用这个命令,sudo dd if=u-boot-sunxi-with-spl.bin of=/dev/mmcblk0 bs=1024 seek=8

但是实际上我昨天烧写,用的命令是sudo dd if=spl/sunxi-spl.bin of=/dev/sdb bs=1024 seek=8

请问到底哪个对呢?

你说的很好,最终结果是芯片没焊接好,那芯片好难焊接啊。

报错信息如上,看上去感觉是不是哪里的环境配错了?

flash启动?tf卡启动?

tf卡启动的,目前检查出来,发现连接晶振部分没有电压,怀疑是芯片引脚没对好。

F1C100s的板子做完了,插上usb后,也能够显示正确的com口,板子本身测量后,几个点的电压也正常。sd卡用的荔枝派的系统,烧写也没什么问题,为什么用putty连接成功后,界面上没有任何输出呢?

各位指点下,我该怎么去排查这问题。

在二线厂做java后端,业余时间研究linux卡片电脑,看论坛其他兄弟从二月份玩到现在都可以做出来一个了,我很惭愧,从去年玩到现在也没做出来,主要是自己不是这个方向的,各种知识都没有。
目前看来需要的知识: 电路图(不会,基本上各处找),pcb(不会,在学习),打板(会),3d建模打印(会),uboot移植(不会),linux裁剪(不会),linux应用开发(会)等。
之前一直玩esp8266,现在玩linux卡片电脑,也算有幸搜索f1c100s的时候看到了这个网站,感觉后面的学习进度就快很多了吧。
菜鸟肯定各位指教。
