Image is too big

Now I'm getting

make[2] package/install
make[2] target/install
make[3] -C target/linux install
WARNING: Image file /home/pi/openwrt/build_dir/target-aarch64_cortex-a53_musl/linux-mediatek_filogic/tmp/openwrt-mediatek-filogic-bananapi_bpi-r3-sdcard.img.gz is too big: 249888768 > 46137344

make -r world: build failed. Please re-run make with -j1 V=s or V=sc for a higher verbosity level to see what's going on
make: *** [/home/pi/openwrt/include/ world] Error 1"

I'm i missing a config for image size ??

Is there some previous history/context here?


Are you really building a 250 megabyte OpenWrt image? What's in the image that requires a quarter-gigabyte of flash?
