Is it possible to specify squashFS images in an .its file? If so, anyone have an example or a pointer to the docs I've been searching for? Hi Mark,
It is possible, here is an example I have used on an NXP LS1043 board: /dts-v1/;
As Matthew's example shows it's totally doable. Furthermore it's not just squashfs it could be any valid initrd. As long as your kernel is configured to expect it u-boot will pass it along.
On that note last time i looked most if the general kernel defconfigs didn't have squashfs enabled.
/ { description = "ARM64 OpenWrt FIT (Flattened Image Tree)"; #address-cells = <1>;
images { kernel@1 { description = "ARM64 OpenWrt Linux-4.4"; data = /incbin/("arch/arm64/boot/Image.gz"); type = "kernel"; arch = "arm64"; os = "linux"; compression = "gzip"; load = <0x80080000>; entry = <0x80080000>; };
ramdisk@1 { description = "ARM64 OpenWrt ramdisk"; data = /incbin/("root.squashfs"); type = "ramdisk"; arch = "arm64"; os = "linux"; compression = "gzip"; };
fdt@1 { description = "ARM64 OpenWrt device tree blob"; data = /incbin/("arch/arm64/boot/dts/ freescale/fsl-ls1043a-rdb.dtb"); type = "flat_dt"; arch = "arm64"; compression = "none"; load = <0x90000000>; };
};
configurations { default = "config@1"; config@1 { description = "OpenWrt"; kernel = "kernel@1"; fdt = "fdt@1"; ramdisk = "ramdisk@1"; }; }; };
Cheers, Matt
