ARM Trusted Firmware in u-boot

Hello,

Does the u-boot that comes with the Toradex Apalis iMX8 QuadPlus module have ATF enable by default?

The buidinfo message that u-boot displays (below) suggests that it is, but wish to confirm.

Thanks

Hi @frankalert ,

By default, the ATF is enabled on our reference images, the imx-atf recipe is added as a dependency for imx-boot recipe here and then imx-boot is added to Apalis iMX8 configuration here.

If you want more information please refer to this article.

Best regards,

Thank You! Would you have any information regarding how to boot QNX from u-boot. I have rebuilt QNX with ATF enabled but it just hangs when I run.

Frank

Hi @frankalert ,

I don’t have experience with QNX but I expect it to work if all necessary binaries are compiled correctly, can you please take a look at this question on NXP community and check if it helps you to solve your issue?

I also suggest you check if every step described in this article is being done correctly.

Otherwise, I recommend you to contact QNX support directly.

Best regards,
Daniel Morais
