=Objective=
In this tutorial we will be discussing how to upload the .hex and .bin files to Lpc1768 board.<br>
For flashing the hex files, we will be using the flash magic software along with a Usb to Serial converter.<br> To upload the .bin, no external hardware is required but  board should have the secondary boot loader.<br><br><br>

<font size="3" color="red">The board is shipped with USB bootloader,  if you want to use it directly follow the steps on how to flash the bin file.</font>

=Generating .hex File=
Check the tutoial [[LPC1768: Keil Project For Hex File|LPC1768 Keil Setup]]  for generating the .hex file using keil.<br><br><br>

=.Hex Using Flash Magic=
You need a USB to Serial(UART) convertor in order to get this working. The neat thing about the NXP controllers is, they come with a UART boot-loader from the factory.

Note: If your converter does not have DTR and RTS lines, "hold down the ISP/PRI_BLD switch, RESET the board(press and release reset switch) and then release the ISP switch ". Now the Boot Contoller will be in ISP/PRI_BLD mode and you can flash the hex file using flash magic.<br><br>

Now open the flash magic software and follow the below steps.
#Select the IC from Select Menu.
#Select the COM Port. <b>Check the device manger for detected Com port</b>.
#Select Baud rate from 9600-115200
#Select None Isp Option.
#Oscillator Freq 12.000000(12Mhz).
#Check the Erase blocks used by Hex file option
#Browse and Select the hex file.
#Check the Verify After Programming Option.
#If DTR and RTS are used then go to Options->Advanced Options-> Hardware Config and select the Use DTR and RTS Option.
#Hit the Start Button to flash the hex file.
#Once the hex file is flashed, Reset the board. Now the controller should run your application code.<br><br>

=Generating .bin File=
Check this tutoial [[LPC1768: Keil Project For Bin File|LPC1768 Keil Setup]]  for generating the .bin file using keil.<br><br><br>

=.Bin File Using Secondary Boot Loader=
For uploading the .bin file, secondary(USB) boot-loader needs to be flashed to the controller. Even though we put a USB boot-loader, the serial boot-loader will be still present to flash the hex files using Flash Magic.

Follow the below steps to upload the new .bin file to LPC1768 board:
#Connect the USB Jumpers.
#Connect the ExploreLpc1768 to system using a USB cable.
#Hold the USB_Btlr switch.
#Press the Reset Switch.
#Release the Reset Switch.
#Release the USB_Btlr switch.
#Now the board will be detected as Explore1768.
#Delete the old firmware.bin file.
#Paste the new .bin file.
#Reset the Board.
#Now your Application code should be running on the board.<br><br>
