Hi all,

I am building Secure Boot environment with iMX8MINI board and
I am tring to generate CSF with the CSF description file by reffering to i.MX_Android_Security_User_Guide.pdf (section 3.1.2).
but following error messages ware asserted on the console when I executed these ./cst commands.


./cst -o csf_spl.bin -i csf_spl.txt
Unsupported argument: File in command AuthenticateCSF


./cst -o csf_fit.bin -i csf_fit.txt
Unsupported argument: File in command AuthenticateCSF

The layout information in the log of make_android.txt is below.

===================Finish building imx8mm_evk_android_trusty_defconfig ===================


csf_spl.txt and csf_fit.txt files were attached.


I do not know how to modify this csf files,so please teach me the countermeasure
and I would like to know what "Unsupported argument" means.

Best regards,
