I'm trying secure boot in develop mode on LS1046A-FRWY with its manual FRWY-LS1046ABSPUG v0.1, but it fails.
I used following steps.

 

1. Edit build_lsdk.cfg

 

    51c51
    < CONFIG_APP_OPTEE=n
    ---
    > CONFIG_APP_OPTEE=y
    58c58
    < CONFIG_FUSE_PROVISIONING=n
    ---
    > CONFIG_FUSE_PROVISIONING=y

 

2. build image
    $ source setenv
    $ flex-builder -m ls1046afrwy -a arm64 -b -s

 

3. deploy the image to SD card
    $ source setenv
    $ flex-installer -f firmware_ls1046afrwy_uboot_sdboot.img -d /dev/sde

 

4. blow OTPMK(described in 3.3.3.1 in  FRWY-LS1046ABSPUG v0.1)

 

5. Boot the image
    - Change switch setting to SD boot
    - Insert SD to the board
    - boot the board

 

At this point, I have expected a prompt for SRK blowing as described in 3.3.3.2, but nothing is displayed.
Please give me some advice.
thanks.
