Linux kernel supports to compress its output binary with lzma algorithm and U-Boot support to decompress lzma compressed image.
Both xz and lzma algorithms are identical and users can use xz utility with format parameter to compress Image which supports lzma algorithm. Add the following command to support lzma. This command is refer to Linux kernel, https://github.com/torvalds/linux/blob/master/arch/powerpc/boot/wrapper "xz --format=lzma -f -6 linux.bin" Signed-off-by: Jamin Lin <[email protected]> --- meta/classes-recipe/kernel-uboot.bbclass | 2 ++ 1 file changed, 2 insertions(+) diff --git a/meta/classes-recipe/kernel-uboot.bbclass b/meta/classes-recipe/kernel-uboot.bbclass index 30a85ccc28..6d4aff6b11 100644 --- a/meta/classes-recipe/kernel-uboot.bbclass +++ b/meta/classes-recipe/kernel-uboot.bbclass @@ -41,6 +41,8 @@ uboot_prep_kimage() { gzip -9 linux.bin elif [ "${linux_comp}" = "lzo" ] ; then lzop -9 linux.bin + elif [ "${linux_comp}" = "lzma" ] ; then + xz --format=lzma -f -6 linux.bin fi mv -f "linux.bin${linux_suffix}" linux.bin fi -- 2.25.1
