Other Parts Discussed in Thread: UNIFLASH

 I created a project using CC 7.4 with projectspecs file in the demo directory and built a .bin file. Then using Uniflash 4.3, generated .sli file and used program image command to download.

The following are screen shots of my Uniflash Project:

    Hi Vijay,

    It doesn't look like the images uploaded correctly. Try uploading them again by clicking the "Insert Code, Attach Files, and more.." link when you post. Then choose the Insert/Edit Media button to attach them. It looks like this:

    The one that I tried to post   was built with no signature file. Since then,  I updated the project with a signature file. However, I couldn't generate an image file. I get an error. Please view the attached document which provides the setup details and the error message I get:

    3122.DocforSerialWifiUniflashSetup.docx

    Hope you are able to view the images .

    Thanks.

    Do you mean that you were adding the MCU image to the user-files without a signature file? If so, there may be an issue with how you are adding the application binary that is causing an issue with the secure boot mechanism.

    I recommend updating to the latest UniFlash Image creator and trying to use the "Simple View" to see if the image boots correctly that way. The simple view will automatically handle adding the MCU image with a signature based on the dummy certificate chain and adding the necessary certificate for the device to validate it on boot. This provides a nice walk through of Image Creator and the Simple View feature -

    I also notice that you have the OTA vendor cert file and ota.dat added to your user files. If these were added based on modifications you made to the serial Wi-Fi example, please try using the default example and make sure that is working. If so, there may be other issues based on how you modified the code.

    Best,

    Thank you for your reply. I tried with the latest Uniflash and was able to create an image successfully in Simple mode. Will go through the basics link to learn about providing the signature file.

    Thanks again,

    Vijay
