Hello ,
I am using iMX8M mini.
I am following the CST code signing tool and the document https://www.nxp.com/docs/en/application-note/AN4581.pdf
These documents talks about signing u-boot.imx , but what about the SPL ? Does it need to be signed and with IVT and other info table ( imx format ) as well as u-boot does ?
Do instead the docs mean an all inclusive u-boot meaning u-boot+spl ?
thank you
Hi Antonio
>Do instead the docs mean an all inclusive u-boot meaning u-boot+spl ?
right. AN4581 was written when spl was not supported with i.mx processors.
In general more updated documentation can be found on
imx\doc - uboot-imx - i.MX U-Boot
Best regards

Thank you that is useful. Which is the command to configure and then build U-boot from those sources for the imx8mm_vk ?
please look at tutorial on
imx\doc - uboot-imx - i.MX U-Boot
"Step-by-step guides are available under doc/imx/habv4/guides/ directory"
introduction_habv4.txt\habv4\imx\doc - uboot-imx - i.MX U-Boot
Best regards
igor
thank you,
I completed the part described on that document and
at the end of that document I can read
The SRK_1_2_3_4_table.bin and SRK_1_2_3_4_fuse.bin files can be used in further steps as explained in HAB guides available under doc/imx/habv4/guides/ directory.
But I cannot find any other document that follows with other steps required to build imx8mm_evk U-boot.
I was expecting to find somewhere where it explains how to configure for the board like "make imx8mm_evk_defconfig "or something similar , but I cannot find it.
additional document was sent vial mail.
