PSVita Ram Dump Test

main.c

#include "fcntl.h"
#define VITA_RAM_SIZE 536870912 //512 megabytes

int main()
{
	int err1, err2, y,x;
	
	//Open dump file
	err1 = sceIoOpen("ramdump.dat", 0, "wb");
	if(!err1<0){return 1;}
	
	//Create a pointer
	unsigned char *mempointer = (unsigned char*)0x00000000;
	
	unsigned char chunck[512]; //512 bytes
	
	for(x=0; x<VITA_RAM_SIZE; x++)
	{
	    if(x==y){break;}//Dump completed
		
		for(y=0; y<512; y++)
		{//Wont really work with restricted memory addresses, but since we have kernel access It doesn't really mind
			chunck[y]= (unsigned char)mempointer[x];
			x++;
		}
		

		err2 = sceIoWrite(err1, (const void *)chunck, 512);
	
	
	
	
	
	}
	
	sceIoClose(err1);
	
	return 0;
}

this doesnt work i tried compiling it i get a main.o file using gcc but if im doing it wrong please explain
