Hello Suresh,
Thank you for brining this up. It is in our planning to update the TI SDK, but I cannot tell you when that will be finished.
You are welcome to try and update the TI Simplelink SDK locally, but we do not have any documentation to do so. I am one of the engineers that has updated the SDK in the distant past. I would recommend opening a diff tool like Beyond Compare and copy only the files that are different between <AWS-FreeRTOS-root>\vendors\ti\SimpleLink_CC32xx\v2_10_00_04 and ti\simplelink_cc32xx_sdk_4_10_00_07. You then must try to build the TI project (https://docs.aws.amazon.com/freertos/latest/userguide/getting_started_ti.html) and work out any issues from there. TI might have changed some of the API, and so this major version update may prove to be not a simple task.
