Now I have changed the code to this:

	IAP iap_entry;
		
	iap_entry = (IAP) IAP_LOCATION; 

	//Prepare sector 
	command[0] = 50;		// Command
	command[1] = 7;			// Start sector
	command[2] = 7;			// Stop sector
	iap_entry(command,result);
/*
	//Erase sector 
	command[0] = 52;		// Command
	command[1] = 7;			// Start sector
	command[2] = 7;			// Stop sector
	command[3] = 60000;  	// System clock frekquency in (CCLK) KHz
	iap_entry(command,result);

	//Prepare sector 
	command[0] = 50;		// Command
	command[1] = 7;			// Start sector
	command[2] = 7;			// Stop sector
	iap_entry(command,result);
*/

	//Write
	command[0] = 51;			// Command
	command[1] = 0x0000E000; 	// Start adress
	command[2] = source;		// Data
	command[3] = 512;			// Size of data 512 | 1024 | 4096 | 8192	  	
	command[4] = 60000;  		// System clock frekquency in (CCLK) KHz
	iap_entry(command,result);


But it still dosent work. If i try to erase it seems like I mess ut
the interrupt vector and if I try "copy to ram" I get SRC_ADDR_NOT_MAPPED.
