RTOS/EK-TM4C1294XL: TM4C1294 Firmware update

Abdul Basit

Part Number: EK-TM4C1294XL

Tool/software: TI-RTOS

Hi,

I have to update my firmware while previous firmware is running from main flash of controller TM4C1294. I want to divide my flash into to partitions. One for firmware 1 and second firmware 2. While running firmware 1, I want to update second half flash with firmware 2 using UART interface. After writing firmware image 2, I will switch pointer to firmware 2 to run current updated firmware. Can you please help me to implement this way? Is there any example code related to this scenario?

thanks,

Basit

Basit,

Offhand I don’t know of any example code for this. Is your firmware using the TI-RTOS kernel? If yes, which version of TI-RTOS?

Thanks,
Scott

Scott,

We are using latest version of TI - RTOS V2.16. I am searching for OTA type firmware update example. If you don't have exact example code, please refer some related document or firmware example.

Thanks,

Basit

Basit,

I’ve searched, and there isn’t any example or specific documentation that I can point you to. There has been some discussion of OTA and reference bootloaders on these two threads:
