 To program the bootloader into the internal flash on the LM3S6965 microcontroller,​ the In-Circuit Debugger Interface (ICDI), that is available on the board, was used. However, this is not required if you have another means of programming the internal flash. To program the bootloader into the internal flash on the LM3S6965 microcontroller,​ the In-Circuit Debugger Interface (ICDI), that is available on the board, was used.

-===== Building and programming the Bootloader ===== 
 Before the bootloader can be used, it needs to be built and programmed into the LM3S6965'​s internal flash memory. The steps in this section only need to be done once. Before the bootloader can be used, it needs to be built and programmed into the LM3S6965'​s internal flash memory.

-===== Configuring Microboot ​===== +===== Building the Demo Program ​=====
-The Microboot utility needs to be configured to connect to the correct COM-port and to communication at the correct baudrate:+
  
-  * Start Microboot by double-clicking "​\Host\**MicroBoot.exe**"​. 
-  * Click the "​**Settings**"​-button and select "​**OpenBLT using UART**"​ from the dropdown box. 
-  * Click the "​**Options**"​-button to configure the communication parameters. 
-    * Select the PC's **COM-port** that the board is connected to. 
-    * Set the baudrate to **57600** bits/sec. 
- 
-Once you saved the settings by clicking the "​**OK**"​-button twice, you can close Microboot by clicking the "​**Cancel**"​-button on the main screen. Microboot is now ready for action! 
- 
-===== Building and downloading the Demo Program =====

-To download this **demoprog_ek_lm3s6965.srec** file to the remaining flash memory using the bootloader, start the **Microboot** program and click the "​**Browse**"​-button. Browse to the "​\Target\Demo\ARMCM3_LM3S_EK_LM3S6965_Crossworks\**Prog**\bin\"​ directory and select the **demoprog_ek_lm3s6965.srec** file to start the download.  +===== Firmware ​update procedure ​=====
- +
-{{:​manual:​demos:​ek_lm3s6965_download.gif?​|}} +
- +
-Once the download completed, the newly programmed software will be started by the bootloader. You can verify this by checking that the status LED blinks periodically. Congratulations! That's all there is to using the bootloader. +
- +
- +
-===== Firmware ​updates from SD-card ​===== +
-In addition to the previously described update procedure with Microboot, the bootloader demo is configured for making firmware updates from an SD-card. The procedure is: +
- +
-  - Insert the SD-card into your PC and store the firmware file **demoprog_ek_lm3s6965.srec** on it. +
-  - Insert the SD-card into the card holder on the microcontroller board. +
-  - Reset the microcontroller to start the firmware update. Once done, the newly programmed firmware is automatically started. +
- +
-The bootloader demo is configured to output log messages to a serial terminal. This enables you to view the progress of the firmware update with a terminal program such as putty. The communication settings are the same as those described above in section **Configuring Microboot**. Additionally,​ the log messages are written to a file called **bootlog.txt** on the SD-card, which can optionally be checked for verification purposes. ​+
  
 +To download the demo program \Target\Demo\ARMCM3_LM3S_EK_LM3S6965_Crossworks\**Prog**\bin\**demoprog_ek_lm3s6965.srec** using the bootloader, follow the instructions in the following links, depending on the communication interface you intend to use:
