AWR2944EVM: Flashing the AWR2944EVM from SDK 4.7 to SDK 4.2 using UniFlash

Part Number: AWR2944EVM
Other Parts Discussed in Thread: DCA1000EVM, UNIFLASH

Tool/software:

Hi TI team,

I'm working with the AWR2944EVM and DCA1000EVM and using the open-source ROS package xwr_raw_ros, which appears to require SDK version 4.2.0, based on the .cfg files provided (e.g., % Created for SDK ver:04.02).

Currently, my radar is running firmware from SDK 4.7, and when I run the config through the ROS interface, the device responds only with repeated CCCCCCCCCCC and never sends Done. I suspect this is due to SDK incompatibility.

My questions are:

1. Is it safe to flash the AWR2944EVM from SDK 4.7 to SDK 4.2 using UniFlash?

2. Can I later re-flash it back to SDK 4.7 without any issues or side effects?

3. Are there any conditions, or limitations. I should be aware of when switching SDK versions on this platform?

Thanks in advance for your help!

    Hi,

    There should be absolutely no side effects in switching between SDK versions as long the device you have is shown as supported in that SDK. Please refer to the mmwave_mcuplus_sdk_user_guide in each of SDK to understand the features supported in that version, you may specifically want to look at chapter 4 which has details related to flashing tools.

    Regards,
