Yocto GTP signed files

Hi,
I am trying to use fastboot to load my images for the dragonboard410c. it doesn't generate the sdcard fiile so I need to do it by hand. I can get it loaded onto the DB410c but when i boot the board I get the error GTP: (Warning) Primary signature invalid) -- Can anyone help on tell me how to resolve this error?
Best Regards,
Rob Berry

Figured it out. I was using the wrong boot image.
