🌟 Support for RT-AX5400 🌟

[gnuton]

*This thread is about supporting RT-AX5400.
If you see this issue here is because I have decided to support this model.

So, feel free to ask questions here about this topic.
I will keep the status updated.

Status:

• received GPL
• received development unit
• Merged GPL to feature-branch
• Initial testing & Bugfixing phase
• Public pre-alphas
• Alpha released
• collecting testing reports & Bugfixing phase
• Beta released
• collecting testing reports & Bugfixing phase
• Stable released

[gnuton]

the prebuild coming within hte GPL do not have compatible prebuilds with the upstream ones provided by Eric, since my models are based on BCM6756(ARMv7) and all Eric's SDK 5.04 models are based on BCM4912 (ARMv8)

Issues:

• src-rt-5.04axhnd.675x/bcmdrivers/opensource/net/enet/impl7/bcm_enet.o
• src-rt-5.04axhnd.675x/bcmdrivers/opensource/phy/prebuilt/phy_drv.o

Solutions:

• sames as for SDK 5.02 (eg: src-rt-5.02axhnd.675x/router-sysdep.rt-ax58u/hnd_extra/prebuilt/bcm_enet.o)

  release/src-rt-5.02axhnd.675x/platform.mk copies the files from hnd_extra to the right directory, but this meachanism doesn't work out of the box

   if [ "$(HND_ROUTER_AX)" = "y" ]; then \
                                        cp $(TOP_PLATFORM)/hnd_extra/prebuilt/bcm_enet.o $(HND_SRC)/bcmdrivers/opensource/net/enet/impl7/bcm_enet$(PRBM_EXT).o ; \
                                else \
                                        cp $(TOP_PLATFORM)/hnd_extra/prebuilt/bcm_enet.o $(HND_SRC)/bcmdrivers/opensource/net/enet/impl5/bcm_enet$(PRBM_EXT).o ; \
                                fi; \
  
  

• b/release/src-rt-5.04axhnd.675x/bcmdrivers/opensource/phy/Makefile
  We could split the prbuilds by chip or build name

DRV_OBJS += $(if $(wildcard $(CUR_DIR)/phy_drv.c),phy_drv.o,prebuilt/$(BUILD_NAME)/phy_drv.o)

any tester?

any tester?

I would enjoy the opportunity to test for this device! I have (2) RT-AX5400 REV B1 new, in-box and (1) RT-AX3000 with Merlin on it in use as my primary home router at the moment.

@Imastupidsalmon you can find the pre alpha image here. This image has not been tested and IT CAN SOFT BRICK YOUR ROUTER.
So please before flashing download the asus recovery tool
https://app.circleci.com/pipelines/github/gnuton/asuswrt-merlin.ng/1726/workflows/5671c5d6-91a1-4efc-8e8e-34a28d2f7188/jobs/6105/artifacts

If you do not feel enough brave to test this pre-alpha image it's fine.. I will test it next week once I get the device in my hands.

[Imastupidsalmon]

I don't mind risking a soft brick at all. Now that I grabbed the restoration utility and stock firmware, and now that I have downloaded your pre-alpha, I will trying flashing it and share the results shortly. Thank you for your work on this and letting me give it a whirl!

No problems so far! Everything I've checked operates as it should, and well, as far as I can tell so far. I just swapped this ax5400 with your pre-alpha on it into place as my home's primary wireless router so that I can give it a more realistic load/test. But so far it's running great, will keep you posted if that changes. Thank you, sir! And great work! If you need me to try something on my end, do let me know and if I can I will.

[gnuton]

Here another tested by myself pre-alpha build

Question, does support for this model mean that ZenWifi XD6 will be technically supported? The product page says they're a pair of AX5400 routers.

I don't know if it's just a different case.

[Imastupidsalmon]

12 days without a reboot. 17 devices connected. Speed is fantastic. Thank you @gnuton ! It's working great for me!

@gnuton Hi, I just came here via the snbforums because my new RT-AX5400 arrived today because I would like to have a fairly simple VPN for 2-3 clients. Unfortunately I miss the kill switch in the stock firmware..

Is the version already final?
I haven't had anything to do with Asus routers so far
And so I don't know if there are different REVs here

greeting

[gnuton]

@Heiliger-Gral it s stable enough

@gnuton
New to firmware installs on routers, was wanting to see where I can download the firmware for this. I can't find it on the main site (https://www.asuswrt-merlin.net/). I found it in the release page of github but only found "RT-AX5400_3004_388.6_2-gnuton1_nand_squashfs.pkgtb"
On all the tutorials online it says it's a .w file, but I don't want to brick my router.
Could I get some guidance?

[gnuton]

@Hollywood25201 the flashing tool checks for the firmware signature. You should allow you to flash garbage.
Even in the worsrt case you can recover but yes the last link is the rcorrect one

[skymansh]

Hi.
It seems that a newer version of the firmware has appeared. Can you tell me if I can install this firmware on RT-AX5400 H/W rev. A1 ?
I'm only interested if I can change the region for better WIFI coverage.

Thank you.
