ARM-CM3 LM3S Texas Instruments EK-LM3S8962 IAR EWARM

Supported firmware update interfaces

RS232 CAN USB TCP/IP SD-card Modbus RTU
Yes Yes No No No No

Development Environment

This demo is targeted towards the Texas Instruments LM3S8962 Ethernet evaluation kit, with 256 kB internal Flash EEPROM and 64 kB internal RAM.

To program the bootloader into the internal flash on the LM3S8962 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 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 LM3S8962's internal flash memory. The steps in this section only need to be done once.

When using IAR EWARM, simply open the workspace from within the Embedded Workbench. The workspace file (lm3s8962.eww) is located at: \Target\Demo\ARMCM3_LM3S_EK_LM3S8962_IAR\Boot\ide\. Once opened, select Project→Rebuild All from the menu to compile all the bootloader sources and link the together into the final executable.

The bootloader program is now ready to be programmed into the internal flash memory of the LM3S8962. 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_LM3S8962_IAR\Boot\bin\openblt_ek_lm3s8962.out
  • \Target\Demo\ARMCM3_LM3S_EK_LM3S8962_IAR\Boot\bin\openblt_ek_lm3s8962.srec

Building the Demo Program

When using IAR EWARM, simply open the workspace from within the Embedded Workbench. The workspace file (lm3s8962.eww) is located at: \Target\Demo\ARMCM3_LM3S_EK_LM3S8962_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_LM3S8962_IAR\Prog\bin\demoprog_ek_lm3s8962.srec

Firmware update procedure

To download the demo program \Target\Demo\ARMCM3_LM3S_EK_LM3S8962_IAR\Prog\bin\demoprog_ek_lm3s8962.srec using the bootloader, follow the instructions in the following links, depending on the communication interface you intend to use:
