SCI based flash programming

Eric,

For each device we provide a flash API.  This API is used for all programming solutions whether it is through code composer studio, SDFlash, an SCI port, etc.  The API does the work of program and erase.  How the customer calls the API is up to them.  In the case of the SCI they can download a small kernel through the SCI port using the bootloader in the boot ROM of the device.  This kernel will then takeover the SCI communication  and make calls to the flash API as required.

 Jeff Stafford put together a great application report that describes this process.  Take a look here:

Cheers,
Lori

 Original Question:

Hi Lori,

I just read your remarks on the url mentioned below.

You mention a way of programming through the SCI port.

Could you please let me know how the customer can do that, or any other way….?

Thanks and kind regards,

Eric.

    Hi Lori,

    My customer wants to program the F28069 in production for the very first time via their Host processor using SCI-A boot mode. We are looking for a CKFA (Communication Kernel and Flash API) example for the F28069 which could be downloaded to the SRAM using the SCI-A boot mode.

    Do we have a similar solution to be used with the F28069?
    I guess there are several differences to the CKFA comparing F281x and F28069 (Flash API, SCI-A configuration…) which might not allow to use this CKFA directly on the F28069.

    Thanks,
    Regards,
    Matthias

    Hi Lori and Matthias, 

    We have the same need for the F28069. We would like to program flash using SCI_Boot.

    As Matthias asked, is there a similar solution using CKFA for the F28069?

    Or, do we need to use the Flash API?

    Thanks,
