芯片:MT7620N

FALSH:25Q128 （winboard）

SDK中的Uboot只能识别4M，烧写大于4M的uImage提示如下：

Bytes transferred = 4450303 (43e7ff hex)
NetBootFileXferSize= 0043e7ff
raspi_erase_write: offs:50000, count:43e7ff
Abort: image size larger than 3866624!

Bytes transferred = 4450303 (43e7ff hex)

NetBootFileXferSize= 0043e7ff

raspi_erase_write: offs:50000, count:43e7ff

Abort: image size larger than 3866624!

查看/driver下的spi_flash.c，没有W25Q128BV，添加后重新编译Uboot然后烧入即可。

{ "W25Q64BV", 0xef, 0x40170000, 64 * 1024, 128, 0 }, //S25FL064K

设置ImageButton按钮，点击后切换到另外一张图片，比如2张图片A,B，初始默认为A，点击完成后切换成B，再次点击，切换成A，这样的效果。

public class MainActivity extends Activity {
	boolean is=true;//设备状态
	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);
		ImageButton btn = (ImageButton)findViewById(R.id.imageButton1);
		btn.setOnClickListener(new View.OnClickListener() {
			public void onClick(View v) {
				if (is) {
						((ImageButton)v).setImageDrawable(getResources().getDrawable(R.drawable.on));
						is=false;
				}
				else{
						((ImageButton)v).setImageDrawable(getResources().getDrawable(R.drawable.off));
						is=true;
				}
			}
		});
	}
}

public class MainActivity extends Activity {

boolean is=true;//设备状态

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

ImageButton btn = (ImageButton)findViewById(R.id.imageButton1);

btn.setOnClickListener(new View.OnClickListener() {

public void onClick(View v) {

if (is) {

((ImageButton)v).setImageDrawable(getResources().getDrawable(R.drawable.on));

is=false;

}

else{

((ImageButton)v).setImageDrawable(getResources().getDrawable(R.drawable.off));

is=true;

}

});

}
