EAP615WALL Snapshot Bootloop

andybjackson · July 28, 2025, 4:09pm

Afraid my EAP615WALL is still bootlooping on the Snapshot sysupgrade image. This despite the resolution of https://github.com/openwrt/openwrt/issues/19403.

What's odd is that it does boot an FTP'ed initramfs-kernel image. As well as the Stable 24.10.2 image. I'm not sure whether the LZMA dictionary size was the root cause, at least of the issues I've encountered.

Now my EAP-235Wall v1 has joined the party. It gets as far as Starting kernel ... and then no further. Doesn't even bootloop.

Anyone got similar experience? For the meantime I have downgraded to 24.10.3 which works.

Have now logged issue 20500 for the TP-Link EAP235-Wall v1. Issue 19403 is still open for the EAP615-Wall.

Hi, I will be able to test this next week. Did your process go with a sysupgrade from an older stable version to snapshot or from snapshot to snapshot or did a new flash with factory.bin fail?

I think I have images for 5.15 kernel snapshot, 23.05.5, 6.6 kernel 24.10.2 and snapshot for both 6.6 and 6.12 at hand to jump through the hoops. I can also start building building the different images today. Hardware won’t be available until early next week though.

andybjackson · October 20, 2025, 8:03pm

Thank you @Nihilokrat. Looking at both more closely, I think the experiences are unrelated. The EAP-235Wall v1 doesn't seem to make use of the same decompression as the EAP-615Wall.

There have been a few mt76 PRs merged in the past few days, and a few bug reports are emerging. I suspect the more recent issue will make itself known.

I was upgrading the 235 using owut from a recent snapshot.

The 615 problem can be solved by a dictionary size change. Although quite why the two would use such different methods is not obvious.

Will follow with interest.

My tests will be with EAP615. So the “fix” mentioned on Github is indeed a fix? I can’t test with the 235, since I don’t have any at hand.

I will be able to test with AX23 and C6v3, which have the same “ingridients”, but haven’t seen any mentions from others regarding an issue like this.

Since 24.10.4 just appeared would it be safe to assume the EAP615 issue is present in it ?

andybjackson · October 22, 2025, 1:00pm

It is SNAPSHOT with the newer (larger) kernel that runs into trouble.

24.10.4 works just as 24.10.3 does.

I will make an attempt to build/test this PR this weekend

ed8 · October 24, 2025, 9:43pm

I started the build process, I hope this is the correct way

git clone https://github.com/DragonBluep/openwrt -b eap615-bootfix
cd openwrt
git branch -a
git checkout remotes/origin/eap615-bootfix
scripts/feeds update -a
scripts/feeds install -a
make menuconfig

make V=s -j $(nproc)

Would have been cleaner to just pull the official OpenWrt repo and apply the PR on top of it, but this should work too.

ed8 · October 24, 2025, 10:09pm

I'm sorry, I have limited experience in this area.
What is the command to pull this PR on top of the official OpenWrt repo?

Applied the compiled sysupgrade.bin - device booted up

I Applied the patch the clean way on top of master like this

git clone https://www.github.com/openwrt/openwrt -b master
cd openwrt
git config --global user.email "me@example.com"
git config --global user.name "ed8"
wget https://github.com/openwrt/openwrt/pull/20509.patch
git am 20509.patch
scripts/feeds update -a
scripts/feeds install -a
make menuconfig
..Target System > Mediatek Ralink Mips
..Subtarget > MT7621 Based Boards
..Target Profile > TP-Llink EAP 615-Wall
..Luci-> Collections->luci *

make V=s -j $(nproc)

upgraded with the sysupgrade.bin from openwrt/bin/targets/ramips/mt7621 and device booted up as well

I will add my results to PR 20509
