CC3220SF OTA bundle upgrade support


I’m using the following modules for my application.

Amazon FreeRTOS 202107
FreeRTOS Kernel V10.4.3
AWS IoT Over-the-air Update v3.0.0

As of now I have done only sys/mcuflashimg.bin upgrade using the OTA.

I am planning to upgrade OTA Bundle, AWS IoT Over-the-air Update v3.0.0 Software module will support this Update? If possible please let me know the process/ document.


Hi Suresh, Thanks for posting the query. Please help in explaining a little more on the current state and next state that you are planning with the OTA.

Hi Shub,

Thanks for your reply,

Currently I am flashing the Service pack, Communication certs (complete bundle of files) using UniFlash and if any changes in firmware, trying to upgrade sys/mcuflashimg.bin (Only single file update) with AWS IoT Over-the-air Update v3.0.0.

CC3220SF-LaunchXL will support the bundle update, so we can flash Service pack, Communication certs (complete bundle of files) using as part of OTA-Upgrade part itself.

For this kind of bundle OTA-Update current AWS IoT Over-the-air Update v3.0.0 SDK supports?


Hi can some one respond for the same…


Hello @Suresh,
If your question is if we will support to update the TI toolchain in amazon-freeartos, then the answer is no.
Please correct me if I didn’t get your question correctly.

Please notice that amazon-freertos is deprecated now, check for more info and ways forward

@ gedeonag,

Thanks for your clarification about the future support.

But My question is (point 2 from below)

The current AWS IoT Over-the-air Update v3.0.0 is having support for upgrading the OTA-bundle?

Point 1) OTA-binary Update (Contains single file i.e., only MCU image)

Point 2) OTA-bundle Update (Contains multiple files in a single rar file ->>>> Meaning MCU Image + TI Service pack + Cloud Certs + etc files )

Bundle is equal to the complete UNIFLASH project files.
