| - | ===== 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! | + | |

| - | 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 ===== |
| - | + | 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: | |
| - | {{: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. | + | |
