Report Devices Here With 18.06.0 Provided Image too big to save overlay

TP-Link TL-WR2543ND v1.0

It has 8 MB flash, so the problems must be caused by something other than the image being too big. If you create a new topic and post the boot log then maybe someone can help you.

Sorry, problem was with router. Maybe bad flash chip, don't know. I've second router, flashed it with 18.06.1 and everything works.

Seems like a partitioning problem.

Thank you for sharing this! I have the same problems with the same hardware. I'm using a Viasat custom version of Netgear WNR612v2 (called WN602v2, yes, no R). I understand it's the same hardware as WNR612v2 but without a RJ45 connector for WAN, which I of course soldered to the board myself. Netgears own firmware for WNR612v2 works flawlessly, so it really can't be any other major differences.

It's wonderful to have all the openwrt capabilities and performance, but I can't get anything above 14.04 to work. I have tried factory img-files, and sysupgrade bin's, but with no success. I get kernel panic at different points during the boot process, either a sync problem or "can't mount". Too advanced for me, but I'd be happy to share logs from serial port if of any use. Using TFTP the router is easily restored to 14.04 every time, but it would be great to be able to run 18.06.1. I realize this is limited hardware, but I'm grateful for any help.
Thanks!

You're out of space, so you have to use a custom firmware with something removed. If you can figure out how to get a serial log you shouldn't have much problems building an image using the guides.
https://openwrt.org/docs/guide-user/additional-software/beginners-build-guide
https://openwrt.org/docs/guide-user/additional-software/saving-space

There is also a web based builder that you can use with the instructions from ginn13 about what to remove: Online ImageBuilder and Upgrade Server

The drawback is that it's harder to know if anything malicious has been added if you use the online builder.

D-Link dir-300 b1 is affected too on 18.06.1

zyxel keenetic v1 has this trouble too on 18.06.1

same problem for TA WA850re v2 repeater, and it isn't supported on 17.01.6!!!

http://downloads.openwrt.org/releases/17.01.6/targets/ar71xx/generic/ (no tiny for 17.01.6, only generic)

same here, any workaround?

See @per post, just above

Also, the WA850 is on the "tiny" target for 18.06 -- see http://downloads.openwrt.org/releases/18.06.1/targets/ar71xx/tiny/

doesn't help! reduced 200k but still config loss on reboot

that is what I'm using. I've built a custom image and saved ~200k (from du report), but still df -h reports 0 free disk, I can't mount on rw mode, no /overlay is mounted, and config is lost on reboot!

I've used

make image PROFILE=tl-wa850re-v2 PACKAGES="uhttpd uhttpd-mod-ubus libiwinfo-lua luci-base luci-app-firewall luci-mod-admin-full luci-theme-bootstrap zram-swap -ppp -ppp-mod-pppoe -iptables -ip6tables -odhcp6c -kmod-ipv6 -kmod-ip6tables -odhcpd -opkg"

On http://downloads.openwrt.org/releases/18.06.1/targets/ar71xx/tiny/openwrt-imagebuilder-18.06.1-ar71xx-tiny.Linux-x86_64.tar.xz

Then flashed the sysupgrade file.

Maybe the problem lies elsewhere. I think you should have gotten an overlay mount anyway, but on RAM disk. Have you checked the logs?

You probably have to use make menuconfig til remove more stuff. 17.01.6 is smaller by default, so if you use it and remove as much as possible you have a greater chance of success.

I'm afraid it wouldn't help, otherwise wouldn't I see 200kb free when I saved by removing packages above?

Because of the block structure there is a threshold you need to get below before it helps. Suddenly you will have enough, and then it will mount.

Tested 15.05.1 and 17.01.5 - no issues. But with 18.06.1 config lost after reboot
