Archivo: DueFlashStorage.cpp Proyecto: nkiraly/DueFlashStorage

void DueFlashStorage::setGPNVMBootMode(bool mode)
{
	//SerialUSB.println("About to set how to boot");
	__disable_irq();

	//flash_clear_gpnvm(1); //boot from ROM for testing
	flash_set_gpnvm(1); //boot from Flash for production


	//SerialUSB.print("Set GPNVM Mode to ");
	//SerialUSB.println(mode);
	if (mode) flash_set_gpnvm(2);
	else flash_clear_gpnvm(2);
	//I think that this becomes active IMMEDIATELY so the sketch will pretty much be guaranteed to crash after this is run.

	__enable_irq();
