Hi, If you know the physical address, then you get virtual address from that physical adress by using ioremap().
Then you can use readl(virtualaddress) to read the string from there Nobin Mathew On 7/10/07, [EMAIL PROTECTED] <[EMAIL PROTECTED]> wrote:
-- Hey all, I know the physical address of a string which is loaded into flash memory. I want to read the string at the known physical memory location from within a kernel module. I initially tried reading the "/dev/mem" file using open(), lseek() and read(). But I guess its not possible to call these functions from a kernel module. Is there some way of reading the contents of this physical memory location from within a kernel module?
