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.
