Sign an image stored in flash to run in SDRAM

[dwhite85]

I am creating an application image that will be stored in flash at around 0x6020_0000 (not the beginning of flash so no FCFB is only reason I mention) on the RT1050 EVKB board.  A bootloader that I have already setup is stored at 0x6000_0000 and will be responsible to loading this application into SDRAM to be run.

When I try to sign this test application though, the MCUXpresso Secure Provisioning Tool does not seem to like the start address of the image.  See picture below.

Is there a stretch of SDRAM that is unavailable for this purpose?  Is there any section I can use to get this image signed? I tried a few locations at random just in case there was a small reserved segment.

Thanks,

Dan

I got some help from an FAE who pointed me to a useful document that comes with the MCUXpresso Secure Provisioning tool.

With the changes suggested here I was able to sign the image
