This is an open-source replacement for the Xilinx bootgen application.
It parses a .bif file and creates a Zynq boot image in the .bin format.
It is written entirely in C.
Required C libraries: pcre, libelf.
To build this application run:
make
To use it, type in:
./mkbootimage [--zynqmp|-u] <input_bif_file> <output_bin_file>
To see all available options, run:
./mkbootimage --help
For Zynq-7000 series, zynq-mkbootimage currently supports creating boot images
containing the FSBL, bitstream, U-Boot, and Linux-related binary files.
For loading Linux-related images, both the [load] and the [offset] attributes
are supported.
As opposed to the original bootgen utility, file extensions are not required.
For example the following .bif file:
the_ROM_image:
{
[bootloader]fsbl.elf
fpga.bit
u-boot.elf
[load=0x2a00000]devicetree.dtb
[load=0x2000000]uramdisk
[load=0x3000000]uImage
}
used with the following command:
./mkbootimage boot.bif boot.bin
will generate a .bin image which can be used in U-Boot, as follows:
bootm 0x3000000 0x2000000 0x2a00000
For Zynq UltraScale+, zynq-mkbootimage currently supports creating boot images
containing the FSBL, bitstream, U-Boot, ARM trusted software and Linux-related binary images.
For example the following .bif file:
the_ROM_image:
{
[fsbl_config] a53_x64
[bootloader] fsbl.elf
[destination_device=pl] fpga.bit
[, destination_cpu=a53-0, exception_level=el-2] bl31.elf
[, destination_cpu=a53-0, exception_level=el-2] u-boot.elf
[load=0x2a00000]devicetree.dtb
[load=0x2000000]uramdisk
[load=0x3000000]uImage
}
used with the following command:
./mkbootimage --zynqmp boot.bif boot.bin
will generate a .bin image, which can be used to successfully boot a Zynq
UltraScale+ machine, and to boot Linux using the following U-Boot command:
bootm 0x3000000 0x2000000 0x2a00000
