The lsdk version is :flexbuild_lsdk2004_update_290520

I use this  command "flex-builder -i mkfw -m ls1028ardb -b xspi -s" and "flex-builder -i mkfw -m ls1028ardb -b sd -s" to generate SD card and xspi boot image .

Then use "flex-installer -f /mnt/firmware_ls1028ardb_uboot_xspiboot_secure.img -d /dev/mtdblock0" and "flex-installer -f /mnt/firmware_ls1028ardb_uboot_sdboot_secure.img -d /dev/mmcblk0" to deploy.

When I set to the corresponding startup mode, I can’t start, and there is no output from the serial port.

CodeWarrior TAP with CCS is used in the prototype design stage. In the production stage, you could write OTPMK and SRK keys to shadow registers under u-boot and blow them to fuse arrays permanently.

Please refer to section "6.1.5 Procedure to run secure boot" in document "Layerscape Software Development Kit User Guide 20.04" downloaded from" Layerscape SDK | NXP

To below OTPMK, put jumper on J28 (TA_PROG_SFP) to supply 1.8 V to PROG_SFP

The following operations must be configured using codewarror and CW TAP?

Is there no other configuration method? Is it too troublesome to operate in a production environment?
