Compressed files missing?

Hi, until now I usually got something like that:

tatel@tiki3:~/OPENWRT/18.06.1/openwrt/bin/targets/ar71xx/tiny$ ls
config.seed
openwrt-ar71xx-tiny-device-tl-wr940n-v6.manifest
openwrt-ar71xx-tiny-root.squashfs
openwrt-ar71xx-tiny-tl-wr940n-v6-squashfs-factory.bin
openwrt-ar71xx-tiny-tl-wr940n-v6-squashfs-factory-br.bin
openwrt-ar71xx-tiny-tl-wr940n-v6-squashfs-factory-eu.bin
openwrt-ar71xx-tiny-tl-wr940n-v6-squashfs-factory-us.bin
openwrt-ar71xx-tiny-tl-wr940n-v6-squashfs-sysupgrade.bin
openwrt-ar71xx-tiny-uImage-lzma.bin
openwrt-ar71xx-tiny-vmlinux.bin
openwrt-ar71xx-tiny-vmlinux.elf
openwrt-ar71xx-tiny-vmlinux.lzma
openwrt-ar71xx-tiny-vmlinux-lzma.elf
packages
sha256sums

But now I'm getting that instead:

config.seed
openwrt-ramips-mt76x8-device-tl-wr841n-v13.manifest
openwrt-ramips-mt76x8-tl-wr841n-v13-squashfs-sysupgrade.bin
openwrt-ramips-mt76x8-tl-wr841n-v13-squashfs-tftp-recovery.bin
_openwrt-ramips-mt76x8-tl-wr841n-v13-squashfs-tftp-recovery.bin.extracted
packages
sha256sums

So root.squashfs and all vmlinux.* are missing?

I was testing kernel size reduction as in Building a smaller kernel for a specific device

Before I was able to see how much smaller it got; now what should I do?

TIA

Maybe there was an error during the build? Check the make V=s output?

It seems to me that you have built for two completely different platforms, not narrowed it down to a specific device. Different platforms have different kinds of firmware files.
