Hi NXP

I am using IMX8MP EVK Board , I want to enable Secure Boot on Android 14. Following is my steps:

1. cd cst-3.1.0/keys

2./hab4_pki_tree.sh

3. cd cst-3.1.0/crts

4. ../linux64/bin/srktool -h 4 -t SRK_1_2_3_4_table.bin -e SRK_1_2_3_4_fuse.bin -d sha256 -c SRK1_sha256_2048_65537_v3_ca_crt.pem, SRK2_sha256_2048_65537_v3_ca_crt.pem, SRK3_sha256_2048_65537_v3_ca_crt.pem, SRK4_sha256_2048_65537_v3_ca_crt.pem

5. hexdump -e '/4 "0x"' -e '/4 "%X""\n"' SRK_1_2_3_4_fuse.bin

6. uboot cmd:

fuse prog -y 6 0 0x2C316710 0x46A7CA37 0x6FAD074B 0xFA86146A

fuse prog -y 7 0 0x8D79AC5E 0xD6E89D73 0x678A9405 0xE386E6A3

7. enable

CONFIG_IMX_HAB=y in uboot

8. build android kernel

9. edit

csf_spl.txt, csf_fit.txt csf_fit_fdt.txt 10.

./cst --i=csf_spl.txt --o=csf_spl.bin

./cst --i=csf_fit.txt --o=csf_fit.bin

./cst -i csf_fit_fdt.txt -o csf_fit_fdt.bin

11.

dd if=csf_spl.bin of=u-boot-imx8mp-evk-uuu.imx seek=$((0x34000)) bs=1 conv=notrunc

dd if=csf_fit.bin of=u-boot-imx8mp-evk-uuu.imx seek=$((0x59020)) bs=1 conv=notrunc

dd if=csf_fit_fdt.bin of=u-boot-imx8mp-evk-uuu.imx seek=$((0x5b020)) bs=1 conv=notrunc

12. copy u-boot-imx8mp-evk-uuu.imx and burn board

13. sudo ./${FALSH_DIR}/uuu_imx_android_flash.sh -D ${FALSH_DIR} -f imx8mp -e -d lvds-panel
