E8350 why not supported by OpenWrt

tcolov · August 22, 2020, 4:43am

Thanks for the feedback.
Make sure you know how to debrick your device if something goes wrong:
https://openwrt.org/toh/netgear/netgear_r7500

can you try the factory image again over the WEB interface?
I've re-uploaded the 7500v1 with minimum packages. (minimal size). May be the image size was the problem as the other part of the build is basically the same.
If it is working with the standard openwrt image. It should be working with this customized test image too.

I have one additional question:

Have you tried sysupgrade -n openwrt..... after you flash it first with the standard openwrt?

I know debrick procedure .
Smaller image was installable directly from netgear firmware.
I can't find 5G radio for wifi in your firmware.
Unfortunately I have no enough time for testing and studying OpenWrt how-to.
I will let you know soon.
Thanks

Can you paste me the output of commands:
cat /etc/rc.local
dmesg
lsmod

NTFS FS package is not pre-installed into the image, you can manually install it:

it is located under the packages directory on the google drive:
https://drive.google.com/drive/folders/1LsIYCS_EU_XXwIVmwNO91gnojiGA6uz7

opkg install kmod-fs-ntfs_5.4.52-1_arm_cortex-a15_neon-vfpv4.ipk

re-plug the drive
and than make sure you can mount & NTFS/files under the openwrt console(directly in openwrt)?
mount
mount /dev/sda1 /mnt - or whatever your mount point is.
df -h
cd /mnt
ls -ls
fdisk -l

Any feedback on the 5Ghz wifi? Have you been able to test it?

xromansx · August 25, 2020, 8:46pm

Tested for some time, seems to be stable speed it excelent, enabled it from ui in Generic 802.11bg how to make possible to set password from it ?

tcolov · August 26, 2020, 7:10am

More wifi settings are in:
cat /etc/rc.local
To edit it with vi
vi /etc/rc.local

zzz · August 26, 2020, 1:48pm

could you please paste rc.local the settings to me with a txt type,only if you change the wifi name and password to blank to test....

tcolov · August 27, 2020, 4:56am

rc.local wifi settings are embedded into the last test image. Once you upgrade you will see it under
cat /etc/rc.local

sysupgrade -n /tmp/openwrt.....ubi

Hi, I was on your earlier e8350 test firmware and I tried upgrading to the latest one with Quantenna wifi but failed. When doing sysupgrade I can't do sysupgrade -n because of the "v1" and I had to use -F to force flash, but after reboot it would be back on the old firmware without the 5G driver. It seems like the flash wasn't successful.
Did I miss anything in the upgrade? Or do I need to flash from stock firmware?

tcolov · August 28, 2020, 8:33am

Use the de-bricking procedure with the factory image(no need to go back to stock)

https://openwrt.org/inbox/toh/linksys/linksys_ea8350_1

zbrandom · August 28, 2020, 12:47pm

I tried that and also unable to flash. Got this after clicking "reboot and recover":

Invalid Image

ERROR - the image you uploaded failed to pass verification.

zbrandom · August 28, 2020, 1:05pm

Update: I flashed stock and successfully flashed factory.bin

Also, it seems like the model name of the router (shown in system status in the overview page) is still incorrect. In the last test build it showed "EA8300 V1", in this version it showed "EA8350 V1" instead of "E8350 V1".

tcolov · August 28, 2020, 3:06pm

I'll fix the model name.
Have you tested the 5Ghz wifi?

flipster · August 28, 2020, 10:46pm

I finally switched to openwrt from stock. I even managed to update to your build. But when trying to activate 5Ghz the rc.local file is empty. (R7500)

zbrandom · August 29, 2020, 4:22am

5G wifi works but I haven't have time to meaningfully test it yet. We try some more stuff over the weekend.

tcolov · August 29, 2020, 6:57am

here is the rc.local, it should be there after sysupgrade of r7500 if you use "-n" option - do not keep the old config files.
sysupgrade -n /tmp/open....
If you add it manually, please make sure it is executable
chmod 755 /etc/rc.local

#!/bin/bash
export PATH=$PATH:/usr/bin:/usr/sbin

Thanks for the quick answer! As I'm kind of new to the game I have a hard time following.
So I made a fresh install of the OpenWRT for the R7500 (v1), after that, I installed your sysupgrade .bin file by flashing it through "Flash new firmware image" under System/Backup / Flash Firmware. Maybe we could start from there. I noticed another thing: Under Network Settings ( DHCP and DNS for example ) all menus appear twice.

Thanks in advance for your answer!

Best

Update: So I did a fresh install (Stock firmware > your firmware) and 5Ghz is available now. The menus do still show up twice though.

Update II: This is how the 5G config site looks like for me. Nothing to edit there:

iivailo · August 30, 2020, 7:40am

There is a size limit for the firmware of Netgear R7500 v1. You cannot install an image larger than 22MB using either the original firmware or the TFTP method.
