Hi,

is it possible to add during image creation with UniFlash (.sli file) to add in the image user files and this image(.sli) to contain user files?

After that, when program the image to multiple devices. 

How to create an image (.sli) for multiple devices? 

When try to program an image on another NWP there is an error for MAC. 

The error is: - FS_DEVELOPMENT_BOARD_WRONG_MAC

Best regards,

Ilian

    Hi Illian,

    Yes you can add user files either in the CCS project you are using, or the Uniflash project (Depending on what tool you use to flash). For the error code, this is because you are trying to flash a development image that is signed to a specific mac address to a different device. When in development mode, images created are locked to specific mac addresses of devices to prevent the use of development images in production. You will need to change the project to production mode to remove this limitation and flash the image on multiple devices.

    Hi Vincent,

    Thanks!

    Yes I was in Development mode and this was the reason for this error.

    I am use this mode because will be good to have an access (to can read or change this user file) after image programming.

    This is not possible on Production mode. When the image, which contain the user file is programmed, after that, user file is not accessible.

    Best regards,

    Ilian

    I create a Project in UniFlas in production mode.

    Add the user file.

    Do Save.

    Burn.

    Create Image

    Save Image.

    After that, using "Program Image from an Image file" program the .sli  image file, which contain the added user file.

    The image is programmed the file also, it is tested. The image can be programmed on different devices.

    After that I am trying to connect to one of the devices with UniFlash and to see the user file. In this case it can not be seen (get or override).

    Best regards,

    Ilian

    Hi Ilian,

    So in production mode, you are not able to see the contents of the File System. This is locked for security reasons. To verify your process is correct, set the device into development mode and verify on one board after you program that you can see the file. This should confirm you have no issues.

    Hi Vincent,

    I understand.

    The question was, whether there is a way the user file to be accessible for UniFlash in production mode, but you confirm, that the answer is no.

    Thanks!

    Best regards,

    Ilian
