ARM-CM3 LM3S Texas Instruments EK-LM3S8962 Crossworks

Supported firmware update interfaces

RS232 CAN USB TCP/IP SD-card
Yes Yes 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 Rowley Crossworks 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 Rowley CrossWorks, simply open the project from within CrossWorks. The project file is located at: \Target\Demo\ARMCM3_LM3S_EK_LM3S8962_Crossworks\Boot\ide\

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_Crossworks\Boot\bin\openblt_ek_lm3s8962.elf
  • \Target\Demo\ARMCM3_LM3S_EK_LM3S8962_Crossworks\Boot\bin\openblt_ek_lm3s8962.srec

Building the Demo Program

When using Rowley CrossWorks, simply open the project from within CrossWorks. The project file is located at: \Target\Demo\ARMCM3_LM3S_EK_LM3S8962_Crossworks\Prog\ide\

The output file is

  • \Target\Demo\ARMCM3_LM3S_EK_LM3S8962_Crossworks\Prog\bin\demoprog_ek_lm3s8962.srec

Firmware update procedure

To download the demo program \Target\Demo\ARMCM3_LM3S_EK_LM3S8962_Crossworks\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:
