Unable to handle kernel paging request at virtual address 200f001c

这个地址有问题

HI_GPIO_WRITE_REG(F_ADDR+F_OFFSET,0x0);//写管脚复用寄存器
而
#define  HI_GPIO_WRITE_REG(Addr, Value) ((*(volatile unsigned int *)(Addr)) = (Value))

一般来说这个Addr应该是 ioremap_nocache过后的地址而不是直接写

用标准的linux驱动的方式来写

试试
在初始化中
reg_base_va = ioremap_nocache(0x200f0000, 0x1000)；

然后
HI_GPIO_WRITE_REG（reg_base_va + 0x1c， 0）；

最终不都是写这个地址的寄存器吗，有什么区别

区别是转换后不会是0x200f001c

0x200f001c是物理地址，而内核能用的是内核地址，两者不一样的， 一般情况下，内核会统一把寄存器用ioremap的方式映射出来，然后定义一个宏给其他驱动来用，不然每个驱动都要去ioremap会出现冲突

多谢庄工指点 收获很大:handshake
之前只是用，原理到没注意，刚Google了一下大概了解，有点类似用户空间和内核空间

[quote]默认外设I/O资源是不在Linux内核空间中的（如sram或硬件接口寄存器等），若需要访问该外设I/O资源，必须先将其地址映射到内核空间中来，然后才能在内核空间中访问它。
　　Linux内核访问外设I/O内存资源的方式有两种：动态映射(ioremap)和静态映射(map_desc)。[/quote]

另外，使用writel感觉效率比海思的地址操作接口高一些:D

谢谢，搞好了在初始化的时候ioremap_nocache   在exit的时候需要iounmap（）

[quote]在加载adv7180.ko的时候[/quote]

请问什么时候需要加载这个文件呢？运行时直接执行./filename就可以了啊？我是新手，在练习例程sample_venc，把它传到板子上修改权限之后./sample_venc就行了啊
