TM4C1294NCPDT: Bootloader functionality implementation on a linux based host.

Bodhayan Nandi

Part Number: TM4C1294NCPDT


I am trying to create an application on a linux based host that handles the firmware update on a TM4C129 chip connected to the host via USB.

My challenge is that the host os is built using yocto and i don't seem to locate the correct recipe in the host build system and the subsequent steps that I need to follow after the inclusion of the recipe. I am pretty new to all of these can anybody help me getting started with this?

Do let me know if TI has any DFU utility for host side suitable to be implemented with a yocto build. Such that I can write a c++ based application to perform the device firmware upgrade of TM4C129 chip from host via the USB interface.

    Hello Bodhayan,

    We do not have any Linux related resources or any knowledge about 'yocto'. All our boot loader resources are for Windows OS.

    You should determine what interface you want to boot load through (UART likely the best option) and then research how to implement a boot loader process through that interface on your Linux host.

    Maybe the dfuprog source code in C:\ti\TivaWare_C_Series-2.2.0.295\tools could be useful to reference.

    Best Regards,
