How to encrypt flash_flexspi target of mk-image for iMX8QX rev C0?

[BrainKub]

I can`t encrypt "flash_flexspi" target of "imx-mkimage" using the same CSF (for "flash" target):

[ERROR] CST: Offsets are not consistent with the input binary to be signed

Offset in CSF correct - they are from imx-mkimage output.

Hi

You need follow this guide 

https://source.codeaurora.org/external/imx/uboot-imx/tree/doc/imx/habv4/guides/mx8m_secure_boot.txt?...

make SOC=<SoC Name> flash_hdmi_spl_uboot

make SOC=<SoC Name> print_fit_hab

What should I do with this value? Tell me please how I can determine the offsets.

[BiyongSUN · Accepted solution]

The guide in uboot does not consider the spi.  

It is for emmc/sdcard. 

So you add 4096(0x1000) to offset for spi as I have given you the link, which is printout by build or in the build log.

Suggest you make sure you can sign the emmc/sdcard image.
