| - | 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\ARMCM4_TM4C_DK_TM4C123G_IAR\**Prog**\bin\" directory and select the **demoprog_dk_tm4c123g.srec** file to start the download. | ||

| - | 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_dk_tm4c123g.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. | ||
