Creating a bootable image

ken1_saito — Tue, 18 Jun 2019 08:52:34 GMT

I am following the document i.MX8 Boot process and creating a bootable image to create a bootable image for MCIMX8M-EVK. I think I already have all I need to create one, but I am not sure which SCFW is suitable for my purpose because there are several variants in imx-sc-firmware.1.2 without any descriptions.

Could anyone tell me which one I should use?

Then I guess I also need to rename it to scfw_tcm.bin to make the image. Is that correct procedure?

Hi Ken,

If you are using a MCIMX8M-EVK board, it includes a i.MX8M processor (4x Cortex-A53), which does not have the SCU (so, no SCFW is required).

The SCU-SCFW is for i.MX8QM (2x Cortex-A72 + 4x Cortex-A53) and i.MX8X (4x Cortex-A35) processors and their MEK boards.

Hope this will be useful for you.
Best regards!
/Carlos

Hi Carlos,

Thanks for your help. Yes, you are right. I thought "Q" in i.MX8QM stands for Quad. Now I understand they are totally different.

Thanks,

Ken
