imx8mm encrypted uboot failed to load linux kernel

yanghongsing1 — Thu, 19 Aug 2021 13:01:37 GMT

I built a encrypted uboot, it can load the kernel image and dtb file, but gave an error of "Could not create optee node.ERROR: system-specific fdt fixup failed: FDT_ERR_NOTFOUND". I hangs there. Please refer to below for details. Could you advise that I used the correct versions of below modules? If not, what are the correct versions?

Hi Hong

one can recheck optee configuration described on

https://source.codeaurora.org/external/imx/uboot-imx/tree/doc/imx/habv4/guides/mx8m_encrypted_boot.txt?h=lf_v2021.04

In general using aligned versions is important, so for v5.10.y recommended to use

https://source.codeaurora.org/external/imx/linux-imx/tree/?h=lf-5.10.y

https://source.codeaurora.org/external/imx/imx-optee-os/tree/?h=lf-5.10.y_2.0.0

Best regards

Dear Igor,

Thank you for your advise.

Could you also advise which version of imx-atf and uboot-imx are aligned to lf-5.10.y? There is no lf-5.10.y at link below:

https://source.codeaurora.org/external/imx/imx-atf

https://source.codeaurora.org/external/imx/uboot-imx

Thanks...

Hi Igor,

I use modules below to build a signed flash.bin and try to generate dek_spl_blob.bin. But I got an error message of "Cannot get OP-TEE device". Could you advise what wrong with me?

uboot-imx: v2021.04

imx-optee-os: lf-5.10_2.2.0.0

imx-atf: lf-5.4.y

imx-mkimage: lf-5.10_2.0.0

Hello Hong,

Could you please check that imx-atf was built with "SPD=opteed" as decribed by the U-boot documentation Igor linked above?

That was my issue when I encountered "Cannot get OP-TEE device".

Best,

Elgin
