帖子: RE: 求助关于6455的8位flash读写问题

flash的BYTE#管脚是怎么拉的，确定是设为8bit模式了吗？

flash是新的没写过吗？要是写过的话，要确保flash是擦除过的才能写。

WriteByte函数不是很严谨，我记得有一个检查某一个线状态的过程，类似于：

int Write_Byte(unsigned int Address, unsigned char data)
{
unsigned int timeout = 0;

//Unlock command
*(unsigned char *)(FlashBaseAddr+0xAAA) = 0xAA;
*(unsigned char *)(FlashBaseAddr+0x555) = 0x55;

//Setup command
*(unsigned char *)(FlashBaseAddr+0xAAA) = 0xA0;

//Write data to destination
*(unsigned char *)Address = data;

do timeout += 1;
while((*(unsigned char *)Address) != data && timeout < 0xffff);

if(timeout ==0xffff)
return -1;
else
return 0;
// flashnext++;

}
