LAUNCHCC3220MODASF: LAUNCHCC3220MODASF

Part Number: LAUNCHCC3220MODASF

Hello,

Although it works Image creation for Secure Device is a lengthy procedure.

I therefore tried following "Image creation for NonSecure Device" (Section 3.4.2), of document "swru461.pdf" (Simple Link Wi-Fi and IoT Solution CC3220, a single chip wireless MCU, GSG), in the hope that it requires far lesser number of clicks on the "Uniflash" utility.

However, when I try to "Program Image" by clicking the "Program Image (Create & Program)" button, as per step 6 of Section 3.4.2 "Image creation for NonSecure Device", the screen shows the error

Operation failed: fs_programming error: ret: -10372, ex_err: 2633 - FS_WRONG_CERTIFICATE_FILE_NAME

The screenshot of same is attached too.

What could I have missed?

    Dear Neeraj - 

    The CC3220S and CC3220SF devices require image to be signed, as they offer the feature and benefit of run-time binary image protection. It is not possible to turn this off or disable image protection. (simply meaning, these variants require a valid certificate chain to be included in the process you are now familiar with). The CC3220R device is the variant of the family which does not require the image to be signed. If you want to go that route - your decision should be based on your application need. The CC3220S-LAUNCHXL LaunchPad can be used to get where you want to go - but you will need to change the IC onboard to an -R part, then proceed forth.
