CC1352P: ODA + BIM, receiving FW over UART, guidance

Christian Engstrand1

Part Number: CC1352P

Dear TI,

We have built our application around the CC1352P with good results. Now we need to add remote FW update.

The CC1352P connects to our cloud service over a 4G module connected via UART. New FW will be downloaded through this interface.

I have recently started reading on ODA + BIM and the concept is perfect for us. We want to run if off-chip, using our MX25R1635 flash. Without the secure boot option.

But we want to use ODA with a FW-image delivered via custom written UART interface.

Can you point me to the best starting point (example/doc/...) for this implementation?

Thanks

Christian

    Hi Christian, 

    Which technology are you using? 

    There is a lot of information about the OAD feature for the different stacks in the corresponding User's Guides that you can find here. This documentation focuses on using one single technology for OAD, for example a BLE target receives an image from the BLE distributor, not mixing technologies and using a custom interface. What's the purpose of using the cloud and a custom UART interface?

    Thanks, 
    Elin

    Hi Elin,

    The purpose is to update the FW and the new FW will be delivered over 4G (UART to the MCU).

    My previous experience is writing my own bootloader etc so I was happy finding the OAD/BIM.

    My question now was more if there was a recommended starting point as I will be using it in a "custom" way. Which project/guide that would be best suited.

    Thanks

    Christian

    Hi Christian, 

    You can probably start with whichever OAD example that fits best to your use-case. We unfortunately do not have any guides for this use-case since all our documentation centers around the OAD solution we provide from Texas Instruments. I believe that you have to make some changes to the BIM too since you will make a propriety OAD solution. 

    Thanks, 
    Elin
