FS#3522 - ath79 Image for TL-WR810N v1.1 causes soft bricked device

newfoundglory:

Flashing the TL-WR810N v1.1 (EU version) with target ath79 is known to cause soft brick. Appears to work with ar71xx target.

There is a warning about this already on the device page: https://openwrt.org/toh/tp-link/tl-wr810n

Problem detailed in forum post:

https://forum.openwrt.org/t/tp-link-tl-wr810n-v1-ath79/48267

I could not find a record of this in the bug tracker, and so I have created one.

It appears that the USB power GPIO is different between ar71xx and ath79. Depending on what a wrong GPIO would do, this at least has a chance of being the root cause to the problem:

https://github.com/openwrt/openwrt/blob/openwrt-19.07/target/linux/ar71xx/files/arch/mips/ath79/mach-tl-wr810n.c#L38

I have adjusted the GPIO for ath79 in a staging branch here:
https://git.openwrt.org/?p=openwrt/staging/adrian.git;a=shortlog;h=refs/heads/wr810n

Please test whether this helps with the issue.

Note that the branch is master, but you should be able to apply the same change to 19.07 easily if you do not want to test with master.

Luckily a forum user was available for testing, so this is fixed in 6934d30
