AM62P: secure boot

Jenney Ni

Part Number: AM62P

Tool/software:

Hi all,

We are testing secure boot on AM62P and we have flash key( cusMpk_am62px.pem cusMek_am62p.txt) on Efuse; But customer didn't successfully boot AM62P HS-SE; So could you provide the customer the images(tispl.bin; mcu.img,linux.img) which can boot after flashing the key. (SBL BOOT)

FLASH process as below:

./gen_keywr_cert.sh -t tifek/ti_fek_public.pem --msv 0xC0FFE -s keys_devel/v15/smpk.pem --smekkeys_devel/smek.key --keycnt 1 --keyrev 1
python3 ../../../../../../tools/bin2c/bin2c.py primary_cert.bin keycert.h KEYCERT
cd <MCU_PLUS_09_01_SDK_INSTALL_DIR>/source/security/sbl_keywriter/am62px-sk/wkupr5fss0-0_nortos/ti-arm-clang
make clean PROFILE=debug
make PROFILE=debug
Flash SD-card ：cp tiboot3.bin /media/jenney/boot

Hello,

Which SBL is being used here? What changes the customer did in the SDK to build the images for HSSE devices?

Thanks!

Which SBL? Maybe you mean SBL SD-card or SBL EMMC? The customer is using SBL SD-card.

The customer changes so many, maybe no useful to refer. So could you guide how to build the boot images above ? It is best to provide the boot images with the default SDK what the customer can use directly in the beginning period.

In that case, I will close this thread as they have already an active thread for this issue:
