+This demo is targeted towards the Texas Instruments LM3S6965 Ethernet evaluation kit, with 256 kB internal Flash EEPROM and 64 kB internal RAM.
 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 compile the demo programs you can use the [[http://www.iar.com/|IAR Embedded Workbench for ARM]] development environment.
 ===== 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.

 The bootloader program is now ready to be programmed into the internal flash memory of the LM3S6965. Using your favorite programmer, flash the bootloader using one of the following files, depending on what file type your programmer supports:
-  * \Target\Demo\ARMCM3_LM3S_EK_LM3S6965_IAR\**Boot**\bin\**openbtl_ek_lm3s6965.out**
+  * \Target\Demo\ARMCM3_LM3S_EK_LM3S6965_IAR\**Boot**\bin\**openblt_ek_lm3s6965.out**
-  * \Target\Demo\ARMCM3_LM3S_EK_LM3S6965_IAR\**Boot**\bin\**openbtl_ek_lm3s6965.srec**
+  * \Target\Demo\ARMCM3_LM3S_EK_LM3S6965_IAR\**Boot**\bin\**openblt_ek_lm3s6965.srec**
-===== 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 =====
 When using IAR EWARM, simply open the workspace from within the Embedded Workbench. The workspace file (lm3s6965.eww) is located at: \Target\Demo\ARMCM3_LM3S_EK_LM3S6965_IAR\**Prog**\ide\. Once opened, select Project->Rebuild All from the menu to compile all the demo program sources and link the together into the final executable.
 The output file is
   * \Target\Demo\ARMCM3_LM3S_EK_LM3S6965_IAR\**Prog**\bin\**demoprog_ek_lm3s6965.srec**
-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_IAR\**Prog**\bin\" directory and select the **demoprog_ek_lm3s6965.srec** file to start the download.
+===== Firmware update procedure =====
+To download the demo program \Target\Demo\ARMCM4_TM4C_DK_TM4C123G_IAR\**Prog**\bin\**demoprog_dk_tm4c123g.srec** using the bootloader, follow the instructions in the following links, depending on the communication interface you intend to use:
+  * [[manual:rs232_demo|Firmware updates using the RS232 communication interface]]
+  * [[manual:net_demo|Firmware updates using the TCP/IP communication interface]]
+  * [[manual:sdcard_demo|Firmware updates from SD-card]]
-{{: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.
