i.mx8m secure boot documentation available?

[thomasdoerfler]

Hi,

we are currently planning an application based on the i.MX8M processor. One of our requirements is secure boot (HAB) which seems to be supported. But we did not yet find a consistent documentation of this.

So: is the application note AN4581 "Secure Boot on i.MX 50, i.MX 53, i.MX 6 and i.MX 7 Series using HABv4" also applicable to the i.MX8M? Is there any further documentation available (or available under NDA)?

Any hints welcome ;-)

I found the following document:

Steps to enable secure boot in i.MX8M Nano

In my case, I'm using the i.MX8M Mini. Is this document also applicable for the i.MX8M Mini?

I wander if there is any update for this issue. Does HAB work in i.MX8M?

[igorpadykov]

it is working in i.MX8M, unfortunately currently there are no

publicly available documentation or examples, one can try to use latest uboot

documentation:

imx\doc - uboot-imx - i.MX U-Boot 

introduction_habv4.txt\habv4\imx\doc - uboot-imx - i.MX U-Boot

Thanks.

There is another question about HAB.

Do you know if following errata is fixed in i.MX8M?

[igorpadykov]

yes they are fixed in i.MX8M.

Thank you for clarification.

My target chip is i.MX8MQ.

For u-boot, I was using the tag: rel_imx_4.9.51_8mq_ga, the suggested branch: imx_v2018.03_4.14.78_1.0.0_ga looks not including all the changes from rel_imx_4.9.51_8mq_ga. Any suggestions?

[igorpadykov]

suggestion to post this on uboot mail list:

U-Boot Info Page 

Best regards
