Linksys EA7500 v1 and OpenWrt?

Thanks for the answer,
did it as per your instructions - the flash is still failing with "incorrect firmware"
Thanks

Maybe this should force the openwrt through TFTP: https://www.linksys.com/us/support-article?articleNum=137928

Followed the instructions, and accidentally flash my router as GPG version!

Can't flash any 3rd-party firmware like OpenWrt. I can't even flash back to other region.

Would serial port do the magic to remove the GPG verify?

Thanks.

Serial flash is for everyone, who can't install anything via stock web GUI. I flashed non gpg version with gpg soft and was able to return non gpg firmware.

If You couldn't, please use serial and tftp instruction.

Did you try to flash the 1.1.2 non-GPG firmware twice and consecutively?

I can't get WAN on the today's snapshots, even compiling them by hand:

Had to return to the November 4th snapshots.

There have been reports on IRC suggesting that https://git.openwrt.org/?p=openwrt/openwrt.git;a=commitdiff;h=a0be58576cfc25f93f10aabf45908f6056d9f848 might introduce a regression for setting up VLANs (vid 2 in particular), reverting that probably fixes your problem.

Yep, after reversing the file to it previous version:

I had only an issue with the Luci install:

I build every couple days (usually with a new kernel version). I keep a backup repository of prior builds - beta software will have hiccups when trying to support such a broad base of devices. Gotta be ready to revert back :sunglasses:

Same issue, any workaround suggestion? :joy:

Now, the website is giving 502 errors...

With snapshot r14935-95b0751d0f. the wifi throughput is weird. I'm using an Intel Ac-8265 card, at less than 2 meters from the router, using the 5 GHz band, on AC mode and 80 MHz of bandwidth, on an empty non-DFS channel.

With iperf3, through the WAN, with Firewall on, and parallel streams:

4
[SUM] 0.00-180.01 sec 4.22 GBytes 202 Mbits/sec receiver

8
[SUM] 0.00-180.00 sec 4.03 GBytes 193 Mbits/sec receiver

Why is this getting more 50% speed with almost 64 streams?

And the speed test (fiber 500/100) is awkward:

Found the issue regarding the odd radio TX rates and bandwidth, on ath10k:

@M10

How did you get a terminal up? I'm game to test images.

While much of this is new to me, I seem to be using all the suggested settings.
20201120_111931
Soldered on TX, RX, GND as pictured in device data
Plugged in Si CP2102, set to 1v8
Installed drivers and noted com port
Set putty to 115200 8n1 no parity & no flow control

When the USB bridge is powered and plugged in, the router hangs on boot, but when disconnected the ea7500 will boot fine. Regardless of timing of connection, I get no data in terminal.

Any guidance available?

Hi,
I am getting EA7500V1 at a bargain. I want to run openwrt on it. Is it fully supported? By that I mean stable wifi (both 5ghz and 2.4ghz) speed and uptime?

Thanks in advance.

Well, despite header voltages looking right and soldering like the example picture, I seem to have cooked my board after a few boots/attempts to get terminal up. The board now only seems to power properly when the ttl leads are connected, but I still don't get a terminal.

do You have 1.8v and 3.3v from board?

@M10
I do get 3.3, but I do not get 1.8 at the tx rx headers. I got a ttl adapter that supported 1.8, but seem to have lost voltage regulation on 1.8 and now rx/tx swing from 1.7-2.5. An led on the back of the board at power cycle button blinks quickly. When the usb adapter is attached it calms down and would seem to boot. Stabilizes the voltage maybe? I haven't tried much after seemingly cooking it.

it looks like You fried 1.8v regulator , any not normal looking components near serial header ?
