[LEDE-DEV] TP-Link Archer C7 boot loop

[Jochen Demmer]

Hi,

yesterday I bricked an Archer C7 v2 by installing some homebrew 
(buildroot) lede firmware. It got stuck in a boot loop and it's also not 
reachable on 192.168.1.1 on any time during boot whatsoever. No failsafe 
mode.
Today I tried an Archer C7 v1 and it also got stuck in a boot loop after 
flashing snapshot. This device luckily has a working failsafe mode. So I 
tried multiple versions with that C7 v1:

# lede snapshot from August 20th sysupgrade, sha256sum: 
9c5332deda79c813efc23c4b7a8b80ea810fa967f4f29b5c9f6e11535d60b994
->boot loop

# lede buildroot commit 7264df388616d2fa21d4cb97336e7e2afe3759ad with 
default .config
-> boot loop

# lede buildroot commit 5d0b180f798ca53cc04be4cec82c7c56b6c25d97 with 
default .config
-> boot loop

# OpenWrt Chaos Calmer 15.01.1 sysupgrade sha256sum 
486c7f96e66b5446b12d2dc27560a533e65dca70de5d1fe0c0981bcb431a2ab5
-> working fine

I don't know how to debug this. Could someone give me a hint? Is maybe 
something wrong within lede for Archer C7 ?

Thank you
Jochen Demmer
