dd if=YEBEI_TDD_8M.bin of=yb.sq bs=1 skip=4882432 count=2971894

安装 squashfs-tools

unsquashfs squashfs_image.sqfs

mksquashfs squashfs-root/ new_squashfs_image.sqfs -comp xz -noappend -b 262144 -no-xattrs -always-use-fragments -all-root

mksquashfs squashfs-root/ new_squashfs.bin -comp xz -b 262144 -noappend

dd if=new_squashfs_image.sqfs of=YEBEI_TDD_8M.bin bs=1 seek=4882432 conv=notrunc
