 # FSBL
+## Build with Docker
 
-FSBL code is at https://github.com/Xilinx/embeddedsw/
-
-there:
 ```sh
-cd lib/sw_apps/zynq_fsbl/src/ && make BOARD=zed CFLAGS=-DFSBL_DEBUG_INFO
+cd docker/compile_fsbl/
+git clone https://github.com/Xilinx/embeddedsw/
+docker build -t compile_fsbl .
+```
+docker build might fail because of firewall settings or the IRS wireguard VPN.
+
+
+To build the FSBL, run the following command in the `docker/compile-fsbl` directory:
+```sh
+docker run -v ./embeddedsw:/project compile_fsbl /bin/bash -c "cd lib/sw_apps/zynq_fsbl/src && make BOARD=zed SHELL=/bin/bash"
+```
+
+If you want, copy the FSBL.elf to the docker/compile_fsbl directory for easier access:
+```sh
+cp embeddedsw/lib/sw_apps/zynq_fsbl/src/fsbl.elf .
 ```
