I am trying to get my LS1021 up and running with secure boot. I have built Linux and Uboot with the -s flag, but when I try to make the firmware using:


flex-builder -c firmware -m ls1021atwr -b sd -s


flex-builder -i mkfw -m ls1021atwr -b sd -s


I get the following output:


Building ATF ... building dependent /home/user/flexbuild_lsdk1909_update_311219/build/firmware/u-boot/ls1021atwr/uboot_ls1021atwr_tfa_SECURE_BOOT.bin ... Please add the dependent /home/user/flexbuild_lsdk1909_update_311219/packages/firmware/u-boot/configs/ls1021atwr_tfa_SECURE_BOOT_defconfig


And I do not see the firmware created in build/firmware/atf


Can anyone provide any insight?
