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.
