TMS320F280025: F28002x FW upgrade example with serial flash programmer

TMS320F280025: Error during SCI boot with serial flash programmer

Dear Champs,

I am asking this for our customer.

They used F280025 control card and our SCI boot kernel example and the serial flash programmer from PC host, but they got this error message below.

The command they used is also on the top of the below figure.

Do you have any comment?

    Wayne,

    As per the error message, it looks like the error is happening at a RAM address.  Please note that the kernels are developed only to program flash - they do not load anything to RAM.  Hence is the error.  Customer should map all the initialized sections to flash only - if they need any code to execute from RAM, they should copy that to RAM from flash at run time.

    Thanks and regards,

    Vamsi

    Dear Vamsi,

    After modifying all initialized sections to flash and adding ALIGN(8), they find it works now.

    Thank you.
