[...] Btw. the image sizes in mktplinkfw also include the reserved space of 262144 bytes. See the option -X in Build/mktplinkfw [1]. My use of the term "final image" might therefore be a little bit misleading - it is just the size which mktplinkfw calculates including the reserved space. But this hasn't changed since Chaos Calmer [2]. And I just saw that Matthias Schiffer also integrated his ar71xx target in OpenWrt. So you might want to check his patch [3] to get a little bit inspired.

Why do you think that you are now using only 6.8MB? The fw_max_len for 8Mlzma devices is 8126464 bytes in mktplinkfw.c. So your final image would be 8376020 bytes large and thus it is rejected by mktplinkfw. The dd before that is from something else (the append-rootfs when I am not mistaken). You might now need to start to remove more things (stuff which cannot be configured but has to be patched) - for example remove unused mach files from the kernel build, remove unused drivers from the kernel, remove unused symbols from large libraries (+ elf sections per function/data + elf section garbage collection during the link), get rid of things which you don't actually use (opkg?), ... ar71xx-tiny from from gluon [1] could maybe also give you some inspiration.

Re: [OpenWrt-Devel] Images are too big in LEDE but not in OpenWRT
two years of development means that lots of packages are larger. you will have to see fi there are config options for the packages that you are using that reduce their size I don't know what configuring limits would mean? not produce an image if it's too large? start leaving things out when it hits a limit?

[OpenWrt-Devel] Images are too big in LEDE but not in OpenWRT
Hello, is there any reason why LEDE needs more empty space in firmware for TP-link tl-wr1043nd v3 ? In OpenWRT 15.01 we are building 7.3MB large images and have just enought space for configs. In LEDE 17.01 is max size ~6.5MB and we are not able to build our images, because we cannot strip more packages, now we are on 6.8MB. Is it possible to configure limits? Thanks for help.
