FS#3418 - Latest build for TL-WR1043ND v2 (ath79) does not boot - missing libs needed by /sbin/init

Device: TL-WR1043ND v2
Software versions: Linux version 5.4.72 (risa@gentoo-vb) (gcc version 9.3.0 (OpenWrt GCC 9.3.0 r14820-5cdc65f6d1)) #0 Sat Oct 31 20:27:47 2020

I am building a the latest snapshot into a custom image by using ImageBuilder, the latest build of r14820-5cdc65f6d1 does not boot, because the `/sbin/init` process misses some libraries. Following is the output from serial console during the failed boot:

but for some reason are not present in the final image built from ImageBuilder.

The image built using the same configuration from the older revision (7190fb2da4) has the size:

-rw-r--r--  1 risa risa 6684973 Sep 20 15:46 openwrt-ath79-generic-tplink_tl-wr1043nd-v2-squashfs-sysupgrade.bin

while the new one built now is much smaller. It looks like some parts are not correctly stored in the image:

-rw-r--r--  1 risa risa 4915501 Oct 31 23:46 openwrt-ath79-generic-tplink_tl-wr1043nd-v2-squashfs-sysupgrade.bin


Richard Musil commented on 31.10.2020 23:51

Another find: When comparing the build logs from the two builds (old=7190fb2da4, new=5cdc65f6d1), I can see that quite a lot of packages are not installed when the squashfs image is built.

Richard Musil commented on 01.11.2020 16:23

After some more investigation of ImageBuilder files, by comparing the build, which is OK (old=7190fb2da4) and the one which is not (new=3440c75986affe02b26d7479071f2b9e1d55366e) I found out that there is a difference in the file `openwrt-imagebuilder-ath79-generic.Linux-x86_64/bin/targets/ath79/generic/openwrt-ath79-generic-tplink_tl-wr1043nd-v2.manifest`.

I do not know, if this file is generated during ImageBuilder build, or is part of the repo, but it seems the lot of libs and modules are missing from the new one. I am attaching the diff.
