hi,
I want to read the gpio4 voltag of Micrel KS8695.When use "IO_ADDRESS",it
return "Segmentation fault". Any idea will be thanks.
#include <asm/hardware.h>
#include <asm/irq.h>
#include <asm/io.h>
#define KS8695_GPIO_MODE 0xE600
#define KS8695_GPIO_CTRL 0xE604
#define KS8695_GPIO_DATA 0xE608
#define KS8695_VA_IO_BASE IO_ADDRESS(KS8695_IO_BASE)
#define KS8695_WRITE(offset, v) __raw_writel((v), KS8695_VA_IO_BASE +
(offset))
#define KS8695_READ(offset) __raw_readl(KS8695_VA_IO_BASE + (offset))
int main(void)
{
u32 uReg;
printf("haha");
uReg = KS8695_READ(KS8695_GPIO_DATA);
return 0;
}
