The following is an example XSCT session that demonstrates creating a FSBL project for a Cortex-A53 processor by manually creating platform, domain and application. Configuration option zynqmp_fsbl_bsp is set for FSBL compiler optimization options.
setws /tmp/wrk/workspace
platform create -name HW1 -hw zcu102 -no-boot-bsp
domain create -name A53_Standalone -os standalone -proc psu_cortexa53_0
domain active A53_Standalone
bsp setlib -name xilffs
bsp setlib -name xilsecure
bsp setlib -name xilpm
bsp config zynqmp_fsbl_bsp true
platform generate
app create -name a53_fsbl -platform HW1 -template "Zynq MP FSBL" -domain A53_Standalone -lang c
app build -name a53_fsbl
