Reading memory regions content at boot time using kernel module
I have a cell phone HTC 10 and I want to read some memory regions content at boot time. I'm using a kernel module which I can run after the boot using insmod and then read the memory content using dmesg. My question is how I can run the kernel module at boot time and read the memory content? My kernel module is located at : system/lib/modules/
#include <linux/module.h>
#include <linux/kernel.h>
int init_module(void)
{
long start_addr;
long end_addr;
long *i;
long *start;
long *end ;
start_addr = 0xffffffbffc00201c; //
end_addr = 0xffffffbffc00303c; //
start= (long*)start_addr ;
end= (long*)end_addr;
for(i=start ; i <= end ; i++ ){
printk(KERN_ALERT "nThe Address = 0x%pn", i);
printk(KERN_ALERT "nThe content = %lxn", *i);
}
return 0;
}
void cleanup_module(void)
{
printk(KERN_ALERT "Goodbye world 1.n");
}
kernel boot memory startup
