Hi, I've found what causes my problems with the squashfs volume. The standard block size using mksquashfs is 128KiB, but OpenWrt's default is 256KiB (-b 256k) causing the failure: mksquashfs openwrt/build_dir/target-arm_xscale_musl-1.1.15_eabi/root-baltosopenwrt/build_dir/target-arm_xscale_musl-1.1.15_eabi/linux-baltos/root.squashfs -root-owned -noappend -comp xz -b 256k -p '/dev d 755 0 0' -p '/dev/console c 600 0 0 5 1' -processors 1 Setting -b 128k works. Also OpenWrt uses bcj filters (-Xbcj arm) for xz which don't work either. I had commented out this option earlier.
