[meta-xilinx] BOOT.BIN creation with hdf files

[Magnus Olsson]

I can only speak for meta-xilinx dizzy branch which is what I use, but AFAIK the only boot.bin generation it supports is the one provided by u-boot-xlnx.


With meta-xilinx, your boot.bin will contain U-boot SPL and nothing else. You can then load FPGA images from U-boot (e.g your fpga.bit). U-boot SPL only needs ps7_init.c and ps7_init.h to build.


If you need to load the FPGA earlier than U-boot in your boot sequence, you need to package boot.bin using the Xilinx SDK tool "bootgen". It allows packaging FSBL, FPGA image and U-boot. AFAIK there is no support for this in meta-xilinx, since it brings in a huge dependency on Xilinx SDK which is not easy to package (nor possible due to licenses I think).

Subject: [meta-xilinx] BOOT.BIN creation with hdf files

Hai,
                I need to generate a custom BOOT.BIN for ZC7030 device with provided hdf that consists of the following:
Ps7_init.c
Ps7_init.h
Ps7_init.html
Ps7_init.tcl
Ps7_init_gpl.c
Ps7_init_gpl.h
Sysdef.xml
Fpga.hwh
Fpga_bd.tcl
Fpga_reg_if.tcl
Fpga.bit


·         Kindly provide the steps required for generating BOOT.BIN using hdf file.

·         In the current yocto build environment I noticed that fsbl source code is present in the path /yocto/ZC702/tmp/work/zc702_zynq7-poky-linux-gnueabi/fsbl-platform-init/2014.4-r0/git/lib/sw_apps/zynq_fsbl/src.

Do I have to copy the above files into this path & issue build command. If yes then what is the build command?
