[guansonghuang]

Hi,

   I usb buildroot(branch: st/2023.02.2) to buid my system.

I want to know how to configure  to enable secure boot.

if i just enable 

TRUSTED_BOARD_BOOT=1

MBEDTLS_DIR=$(MBEDTLS_DIR)

then compile error as follow

 make[2]: *** No rule to make target '/home/gary/test/stm32mp15/buildroot/output/build/mbedtls-2.28.2/library/aes.c', needed by '/home/gary/test/stm32mp15/buildroot/output/build/arm-trusted-firmware-hgs_test/build/stm32mp1/release/libmbedtls/aes.o'. Stop.

Hi @guansonghuang ,

Have you tried following this wiki page to configure secure boot?

Yes I have read this article.but it talk  about some concepts of secure boot.  not operational steps
