Build for Netgear R7800

You need to first opkg remove the -ct blob

(Opkg complains to you that you want to overwrite it with a file from another package)

Iv4nI · February 27, 2021, 3:20pm

OK. Did that, too.
I hope everything works now.

Btw. you should see the full version number loaded into your WLAN cards in dmesg after rebooting, e.g.:

ath10k_pci 0000:01:00.0: qca9984/qca9994 hw1.0 target 0x01000000 chip_id 0x00000000 sub 168c:cafe

Been on master up until recently so i just sysupgraded every time i wanted to update the base,curious if now that i'm on the 21.02 branch its safe to just run a full update from opkg or if i should sysupgrade again to your build today.

edit: there is no build today, misread, but more of a general question i suppose

hnyman · March 1, 2021, 4:58am

There is no safe "full update" with opkg.

Opkg is only suitable for upgrading selected individual packages. It can't upgrade kernel, and there are difficulties with low-level system packages.

Just use sysupgrade every now and then.

Test-DSA-kernel510-master-r16135-7e7218d133-20210307

I have compiled a test version with kernel 5.10 and DSA switch config.
That is based on commits from @Ansuel in PR
https://github.com/openwrt/openwrt/pull/3954

Discussion and advice at
[WIP] [PR] ipq806x: kernel 5.10 bump code propose

I have been running 5.10 with DSA for a day, and so far no problems.

wireless · March 10, 2021, 9:45pm

Hi hnyman,
does it mean you are going to use in your builds the code for NSS made by Ansuel (and others)?!? Uh hu!!! What a happy news!

Ansuel · March 10, 2021, 10:01pm

nope... dsa is not nss
it's just new kernel with new upstream driver

streilu · March 11, 2021, 7:16am

What has to be changed in config for using DSA? I'm only using VLAN on WAN for internet access.

hnyman · March 11, 2021, 7:32am

all references to the hardware interfaces: eth0 eth1 eth.2 etc.

wan interface is not eth0.2, but just "wan".
lan is directly the 4 ports as 'lan1 lan2 lan3 lan4'

With default settings, only this change in the network config itself:

And the wan LED config:

With those changes made before sysupgrade, I am able to sysupgrade with other settings intact. I do not use any VLANs.

But additionally, all stuff related to sqm, bcp38, whatever..., where references to the hardware interface names are used in config.

streilu · March 11, 2021, 8:22am

Thanks a lot, I will give it a shot.
Just have to find out how to tag WAN to VLAN 3201.

hnyman · March 11, 2021, 8:24am

You should probably ask help in the threads specific to ipq806x and kernel 5.10 with DSA:

(I do not want this R7800 build thread to get stuck into DSA debugging & advice, as those items are more wide and generic than my test build)

RainGater · March 13, 2021, 2:38pm

@hnyman Thank you for providing builds and much appreciate it. I have used OpenWRT couple of years ago until I retired R7800. Now, it's alive again.

I see there are two builds: openwrt-21.02 and openwrt-19.07. Which one do you recommend?

I am planning to flash your firmware from Voxel (OEM). So, flashing via stock GUI should work, correct? If not, I will try tftp.

hnyman · March 13, 2021, 2:50pm

21.02 was branched off master just a month ago. It is two years newer than the old 19.07. There is not yet any 21.02 releases or even RCs, but soon there will be.

Personally I mainly use the actual master. (although I run these pretty much round-robin fashion, due to testing all builds I upload)

No idea about Voxel.

But it makes no sense to flash the OEM between Voxel and OpenWrt. Just skip the OEM firmware and use the TFTP flashing method.

RainGater · March 13, 2021, 5:15pm

I am confused. If there are no builds for 21.02, what is this "R7800-owrt2102-r15874-ceb6869cd9-20210304-2223-factory.img"? Isn't this the latest?

So, you are using "R7800-master-r16178-1cd098784e-20210313-1827-sysupgrade.bin"?

I didn't mean to say that I am going to flash OEM to get to OpenWRT. Voxel is nothing but OEM with some performance optimizations.

hnyman · March 13, 2021, 5:26pm

I meant that there are not yet any official release builds.

Buildbot is crunching the packages etc., but so far there is no formal 21.02-rc release.

I build already from the 21.02 branch, so yes, for my community builds there already are 21.02 builds.

RainGater · March 13, 2021, 5:51pm

So, you are using "R7800-master-r16178-1cd098784e-20210313-1827-sysupgrade.bin"? I just want to get your latest, similar to what you have to try it. Thanks again for your prompt response.

infirit · March 13, 2021, 6:20pm

Which file to use for flashing is identical to stock openwrt, this is described on https://openwrt.org/docs/guide-user/installation/generic.flashing. The sysupgrade file is very likely not what you want.

The R7800 can be put into tftp (unbrick mode) very easily see Netgear R7800 exploration (IPQ8065, QCA9984) - #5 by hnyman

How to flash openwrt with tfpt can be found at https://openwrt.org/docs/guide-user/installation/generic.flashing.tftp

hnyman · March 13, 2021, 7:33pm

I have three different "latest", from different branches:

Branch	Version
master	master-r16178-1cd098784e-20210313
stable openwrt-21.02	owrt2102-r15874-ceb6869cd9-20210304
stable openwrt-19.07	owrt1907-r11318-c64742a96e-20210308

Try the 21.02 build...

RainGater · March 13, 2021, 7:48pm

Thank you again for all your builds and the fast response is much appreciated. Will try the R7800-owrt2102-r15874-ceb6869cd9-20210304-2223-factory.img and let you know how it goes.
