While trying to flash my DL40 on a socket with the connector on * the procedure stops on [quote]Connecting…[/quote]
I hope that I’m missing something but I can’t figure out what.
LPC1113F is different than the LPC1111 but I guessed that was ok.
NXP.Frequency.MHz_72 and NXP.Frequency.MHz_168 didn’t make the difference and I also don’t know which one I should use.
public static Thread flashThread;
public static InterruptPort _button;
public static byte[] binFile = Resources.GetBytes(Resources.BinaryResources.DL40);
public static SerialPort serial;
public static GT.Interfaces.DigitalOutput reset;
public static GT.Interfaces.DigitalOutput loader;
public static bool doneFlash = true;
void ProgramStarted()
{
var socketNumber = 9;
loader = new GT.Interfaces.DigitalOutput(Gadgeteer.Socket.GetSocket(socketNumber, true, null, null), GT.Socket.Pin.Six, true, null);
reset = new GT.Interfaces.DigitalOutput(Gadgeteer.Socket.GetSocket(socketNumber, true, null, null), GT.Socket.Pin.Seven, true, null);
_button = new InterruptPort((Cpu.Pin)24, true, Port.ResistorMode.PullUp, Port.InterruptMode.InterruptEdgeLow);
_button.OnInterrupt += _button_OnInterrupt;
serial = new SerialPort(Gadgeteer.Socket.GetSocket(socketNumber, true, null, null).SerialPortName, 9600, Parity.None, 8, StopBits.One);
serial.Open();
}
void _button_OnInterrupt(uint data1, uint data2, DateTime time)
{
if (doneFlash)
{
doneFlash = false;
flashThread = new Thread(DL40FirmwareThread);
flashThread.Start();
}
}
static void DL40FirmwareThread()
{
Debug.Print("Beginning chip reflash...");
loader.Write(false);
Thread.Sleep(100);
reset.Write(false);
Thread.Sleep(100);
reset.Write(true);
Thread.Sleep(400);
NXPFlashLoader.CommunicationInterface com = new SerialPortToNXP(serial);
NXP.Programmer p = new NXP.Programmer(com, NXP.Chips.LPC1111, NXP.Frequency.MHz_72);
Debug.Print("Connecting...");
p.Connect();
Debug.Print("Connected!");
Debug.Print("Erasing...");
p.EraseAll();
Debug.Print("Erased!");
Debug.Print("Converting File...");
p.SelectDownloadBuffer(binFile, 0, binFile.Length);
Debug.Print("Converted!");
Debug.Print("Downloading...");
p.Download();
Debug.Print("Downloaded!");
Debug.Print("Verifying...");
p.Verify();
Debug.Print("Verified!");
Debug.Print("Board Flash Complete!");
doneFlash = true;
}
}
The thread hangs on com.read(cmdBuffer, 0 , 1, TIMEOUT); :
public void Connect(){
byte[] dummyBuffer;
com.Initialize();
com.Purge();
// send "?"
com.Write(Encoding.UTF8.GetBytes("?"), 0, 1);
// Read "Synchronized"
long initialTime = DateTime.Now.Ticks / 10000;
do {
com.Read(cmdBuffer, 0, 1, TIMEOUT);
if (cmdBuffer[0] == (byte)'S')
break;
} while (((DateTime.Now.Ticks / 10000) - initialTime) <= TIMEOUT);
}
I hope someone see’s my mistake. Thanks in advance
