Openwrt- Failed creating firmware layout description

I am trying to build kernel image for VoCore v1.0. I got the sdk files form github. While doing so I got an error as follows

/build_root/openwrt/staging_dir/host/bin/padjffs2 /build_root/openwrt/build_dir/target-mips_34kc_musl-1.1.11/linux-ar71xx_generic/tmp/openwrt-ar71xx-generic-ubnt-ls-sr71-squashfs-factory.bin  4 8 16 64 128 256

I did some searching on the error and I find out that this error is generating from "mkfwimage.c" file, but I don't really get any useful information to remove such an error.

Reason for this error: It turns out the mkfwimage error was generated indirectly from performing a build that exceeded the flash size of the target device.

Help me avoid this error

Solution

  • 1) Try downloading the OpenWRT Chaos Calmer version with git clone git://git.openwrt.org/15.05/openwrt.git.

    2) Run make menuconfig on command line in the OpenWRT folder.

    3) Select ONLY the following items on the menuconfig:

    • Target System >> Ralink RT288x/RT3xxx
    • Subtarget >> RT3x5x/RT5350 based boards
    • Target Profile >> VoCore

    4) Apply this path:

    diff --git a/target/linux/ramips/dts/VOCORE.dts b/target/linux/ramips/dts/VOCORE.dts
index e6288b0..29867ed 100644

                };
            };

    5) Run make clean and make all on command line.
