Part Number: TM4C129DNCPDT
Other Parts Discussed in Thread: SYSBIOS

Hi, 

   I need to program TM4C129 using Beaglebone black. I am using Tivaware driver lib and Ti- RTOS. Planning is given below.

 

Which example i need to follow. I am planning to go with flash type bootloader. If any one have others easy and good option please suggest.

Regards,

    Hi,

      The boot_serial is the flash-based bootloader to program/upgrade application firmware on TM4C129 MCU. The boot_demo1 is an example application that is programmed through the UART port by the bootloader. You can use LM Flash Programmer running on the host PC to download the application application image. Since you are using a Beagle Bone then refer to this app note for implementation of a programmer on the host side for serial bootloading. 

    https://www.ti.com/lit/pdf/spma074

    TivaWare also has the source code for the sflash command line utility at C:\ti\TivaWare_C_Series-2.2.0.295\tools\sflash. You can refer to sflash to build your utility running on the Beagle Bone.

    Hi Charles,

    Thanks for suggestion.

    I have tested, it is working with UART0. I have tested the example code, boot_serial and boot_demo1.

    I my case, I have program though the UART1.

    So how to change UART0 to UART1?

    What is the process, I have to follow for this?

    I was trying to open the boot serial example code to modify the UART PORT but unable to open.

    I am getting this type of message.

    I copied and pasted at another folder but same message I got.

    Regards,

    Hi,

      Please refer to the bl_config.h file where you can configure the UART port that you want to use for serial bootloading. Below is the snippet of code that currently configures UART0 for serial bootloading. You can change it to UART1 for your project.

    Hi, Charles,

    After change i have to build boot serial example code?

    Yes, you need to change boot_demo1 example from UART0 to UART1 and rebuild boot_demo1 again.

    Hi Charles,

    Thanks for Quick reply.

    So, I have to change this file from example code.

    Then Need to build the project source code(boot_demo1).

    am I right Charles? 

    Regards,

    Sumit

    Yes. You need to modify the bl_config.h file shown in your screenshot and rebuild the boot_serial example. You also need to modify boot_demo1 to change from UART0 to UART1 as I mentioned in my last reply.

    Hi Charles,

    Thank you so much for instruction. I followed your instructions and it's work's fine. 

    But now i got some new issue.

    Now i am trying to integrate the bootloader with my actual source code, But i am getting some error.

    I think something i have to change, but i don't know that is that.

    Working Environment: TM4C129DNCPDT, TI-RTOS, TIVAWARE Driver lib.

    Before change the cmd file for bootloader

    After Change the cmd file for Bootloader

    Hi Charles,

    Thanks for instruction.

    Problem solved everything is working fine.

    Now i have another point.

    If new application is failed to load because of some issue (communication fail, Power fail, etc.) 

    Controller should be bootup with old application after reset.

    So, what do the steps i have to follow?

    Thanks and regards,

    Sumit

      You can use CHECK_CRC to verify if the new application is programmed successfully. Refer to CHECK_CRC in the bootloader user's guide for details. 

    SUMIT CHAULYA said:

    Controller should be bootup with old application after reset.

    The current bootloader will overwrite the existing old firmware with a new firmware. It does not retain the old application. It will be up to you to customize the bootloader and to divide the flash into two different sections where the bootloader will update one of the program images and decides which one to jump to after power up.
