Hi!

I'm pretty new on this and I think i screwed it up really good directly

I made this code and tried it:

void writeToFlash()
{
	command[0] = 54; 
	iap(command,result,0x7FFFFFF0);
		
	command[0] = 55;
	iap(command,result,0x7FFFFFF0);

	//Prepare sector 
	command[0] = 50;		// Command
	command[1] = 8;			// Start sector
	command[2] = 8;			// Stop sector
	iap(command,result,0x7FFFFFF0);

	//Erase sector 
	command[0] = 52;		// Command
	command[1] = 8;			// Start sector
	command[2] = 8;			// Stop sector
	iap(command,result,0x7FFFFFF0);

}

Offcourse it didnt work because I forgot to set the CCLK in the erase
part. 
But this was not all, after this I cant access the CPU again. I get
this error message: "Memory Missmatch Adress: 0x00000000 Value = 0x00
Expected = 0x18". 
Have I screwed up the CPU totally or is there anything I can do to
make it work again?

Please can someone help me?

Thanks
