HAB Script

norratheprattan — Fri, 15 Jul 2016 06:40:30 GMT

Hi,

I'm planning to enable HAB on Sabre Lite and I have been reading HAB user's guide and it mentioned about contacting Freescale for retrieving ./mk_secure_uboot and ./mk_secure_uimage scripts.

Is this the place where I can request those scripts or which one should I contact?

Thanks,

Hi Norrathep

please look at imx-test package folder ../mxc_secureboot

www.nxp.com/lgfiles/NMG/MAD/YOCTO/imx-test-5.4.tar.gz

Best regards

Thanks Igor. I have another question. Based on my understanding of HAB and HAB uImage Layout, uImage is authenticated as a whole by u-boot. and it seems to be the case for that script.

Is there a code (and/or is it possible at all in HAB) for authenticating only a partial uImage since some parts of our image (at the end) should support a code update.
