The following example shows the detailed manner in which you can write a BIF while grouping the partitions together. The BIF syntax has changed for Versal ACAP to support the concept of subsystems, where multiple partitions can be combined to together to form an image, also called as subsystem with one image header.

{
	id_code = 0x04ca8093
	extended_id_code = 0x01
	id = 0x2
	image
	{
		name = pmc_subsys
		id = 0x1c000001
		partition
		{
			id = 0x01
			type = bootloader
			file = gen_files/executable.elf
		}
		partition
		{
			id = 0x09
			type = pmcdata, load = 0xf2000000
			file = topology_xcvc1902.v2.cdo
			file = gen_files/pmc_data.cdo
		}
	}
	image
	{
		name = lpd
		id = 0x4210002
		partition
		{
			id = 0x0C
			type = cdo
			file = gen_files/lpd_data.cdo
		}
		partition
		{
			id = 0x0B
			core = psm
			file = static_files/psm_fw.elf
		}
	}
	image
	{
		name = pl_cfi
		id = 0x18700000
		partition
		{
			id = 0x03
			type = cdo
			file = system.rcdo
		}
		partition
		{
			id = 0x05
			type = cdo
			file = system.rnpi
		}
	}
	image
	{
		name = fpd
		id = 0x420c003
		partition
		{
			id = 0x08
			type = cdo
			file = gen_files/fpd_data.cdo
		}
	}
}

The following example shows how you can write a BIF in a concise manner by grouping the partitions together.

new_bif:
{
	id_code = 0x04ca8093
	extended_id_code = 0x01
	id = 0x2
	image
	{
		name = pmc_subsys, id = 0x1c000001
		{ id = 0x01, type = bootloader, file = gen_files/executable.elf }
		{ id = 0x09, type = pmcdata, load = 0xf2000000, file = topology_xcvc1902.v2.cdo, file = gen_files/pmc_data.cdo }
	}
	image
	{
		name = lpd, id = 0x4210002
		{ id = 0x0C, type = cdo, file = gen_files/lpd_data.cdo }
		{ id = 0x0B, core = psm, file = static_files/psm_fw.elf }
	}
	image
	{
		name = pl_cfi, id = 0x18700000
		{ id = 0x03, type = cdo, file = system.rcdo }
		{ id = 0x05, type = cdo, file = system.rnpi }
	}
	image
	{
		name = fpd, id = 0x420c003
		{ id = 0x08, type = cdo, file = gen_files/fpd_data.cdo }
	}
}
