@晕哥，试了下你的代码，在我的上面出现 gpio: can't request region for resource [mem 0x01c208a0-0x01c208a3]报错，可以正常卸载，dts可能有问题。

@晕哥，现在根文件系统能启动，自己编译的.ko点灯不行

我编译app .ko 和内核用的是 arm-linux-gnueabi-gcc，编译根文件系统用的是 Sourcery CodeBench ARM 2014.05
这样有问题吗？还是其他问题。

include_h · 全志 SOC

准备先换一个高版本的buildroot，改一下buildroot的Toolchain选项，没辙了就照8楼那样搞了。

include_h · 全志 SOC

这个关闭了原先，我刚刚测试一下，

这个版本的buildroot最大选择内核头文件选4.12.x, 但实际上内核头文件版本用的是4.15.x , 这里会有问题吗？

@EddyZhan @晕哥我的buildroot配置如下

@EddyZhan 大神，能否共享一下你的根文件系统，您是参考 https://whycan.cn/t_1017.html
这种方式修改的根文件系统吗？我使用自己编译的根文件系统出现下面这种情况，怀疑是上面的链接所说的不能使用Linaro工具链编译nano的根文件系统：

我自己使用主线4.15.0的内核,从spi-flash 启动出现

后不会出现上面信息，看样子不能正确识别到spiflash里的分区信息。

include_h · 全志 SOC

@晕哥，能贴出将它编译成.ko文件的脚本吗？
友善的A9 4412是Makefile这样的,现在换到全志我转不过来，

FILE =  key_poll
INC =   key_poll.h

obj-m = $(FILE).o

KDIR = /works/linux/linux-3.5/

all:
	make -C $(KDIR)  M=$(PWD)  modules
