Anything I can do? The fact the board-2.bin file shows in two different packages is not overlaping it, right?

I'll work with the v1 version I have to validate which board data file it's using.
Stay tuned.

Build for WHW03 V1 version that has wifi detected, kernel is 4.19.
Will try to port to 5.4.
Only for testing!

Output is squashfs and ext4, since being an eMMC perhaps ext4 is more suited.

Will work to have upgrade/install tools fixed to work with eMMC -- if anyone has a hint, would be much appreciated.

F A N T A S T I C! Great work @flipy!!

It worked great, WiFi is working. Radio 1 and 2 works as expected but I was not able to get radio 0 to work (QCA9888), I mean I can see the radio with iw/ifconfig and drivers loaded but the WiFi network will not come up. I assume that this is the radio usually dedicated to the mesh between the velops, maybe related to this:

New WHW03 v1 build based on kernel 5.4.

Corrected device tree along with kernel bump.

Still for testing only as sysupgrade most likely will fail or corrupt some critical partitions.

@flipy, pretty stable for me, wlan1/2 working properly, good throughput, no kernel dump this time for the same high speeds as well, 200Mbps up/down.

Wlan0 still not comming up, my attempts to get it up resulted in wlan1/2 not working properly, if I enable wlan0, wlan1/2 will not come up. When trying to bring wlan0 up got this:

eMMC, serial, switch, everything working as expected and as on the previous firmware, all good. LuCi is installed and working well on this build.

Will do more tests and report in the coming days.

I've been using it for 2 days now and it proved to be stable, using on a regular basis, my daughter having online classes for 3/4h a day just with one issue where the network went down (wifi) and putting the wifi password again didn't solved, tried 2 times before it worked. The only think that was reported on the serial at that time was:

Find here a new build for WHW03 v1.

Do let me know if it proves to be more stable -- it is base on a recent commit from master, so once they create the new stable branch I'll switch the port.

Still working to figure out how to upgrade/install the build, and currently looking at ext4 builds.
There are few devices that have only eMMC.

Changelog:

  • correctly load data from devinfo partition, such as hw base MAC address
  • set up MACs for all interfaces (eth and wlan)
  • configure u-boot tools (although I'd recommend not to tinker with them unless necessary)

First thing I've noticed is that interfaces eth0/1 got switched, no issue for me but just as FYI. On previous version eth0 was WAN and eth1 was LAN, on this one is the oposite, just fixed my config and it is running fine.

I was able to make all the radios work now. For wlan0 (mesh radio) I obviously had to use one of the channels from 100-161 and it went up as AP. I was even able to make it connect as client to the other velops on the network and use is was WAN but it was tricky, I had to configure wlan0, disable all radios, enable wlan2 than 1 than 0 otherwise if I put 0 up, 1 and 2 will disable.

On the file format, think that ext4 is best, that's was is being used for the eMMC root partition orinally on the velop, right?

I'll take a look on the other similar threads with eMMC devices and will see if I get any ideas, think will be difficult as you're clearly more expert than me on that.

Will test it for a couple more days and will report.

@flipy, do you think it is worth adding an entry into OpenWRT TOH so see if there are other people with knowledge like you interested in helping on this specific case of the eMMC? If worth, I can gather the information and include there, just let me know.

I've only tested fw_printenv so far and it properly shows the env variables I got from U-boot. Was wondering if I could change one of the boot parameters so I could make them tftp by default and get the other 2 devices running elsewhere at home.

Also, trying to mount the ext4 partitions was not working this time, kmod-fs-ext4 wasn't compatible with the built kernel but understand it is because you're building on the latest master branch.

Following with interest... I also have a WHW03 v1, and would love to put OpenWRT on it. @flipy, Can this be done with just tftp type access, or what do I have to do to load these builds?

Right now it is only usable thru TFTP and loading an initramfs image, as I am still working on the install/upgrade process.

I have to say that seems to be stable enough, although @gabriel.hahmann did more testing than I could.

Great, thanks. No problem with tftp - I just put "openwrt-ipq40xx-generic-linksys_whw03-initramfs-fit-zImage.itb" to the router, or openwrt-ipq40xx-generic-linksys_whw03-squashfs-factory.bin ?

Apologies, I should have been more clear.
Although TFTP is the way to send an image to the device, it does require serial access to it and you need to open the device and hook/solder connectors to it.

New build for whw03 v1.
The major change is the ability to use sysupgrade and install it on the device, with some caveats and serial access required.
As always, build for development only -- it is full of tools I've been using to debug/test the install process.

Install procedure:

  1. Pause u-boot, and load bootargs from an existing variable.
    For instance: set bootargs $partbootargs2.
  2. Load TFTP image and boot.
  3. Copy the sysupgrade file to a temporary directory.
  4. Run sysupgrade -n sysupgrade.bin.

Warning: since the install logic will install on the inactive partition, it is recommended to always force the install process on the same partition -- by using the same bootargs.

Caveats:

  • not possible to install from factory yet, I need to understand how Linksys applies a magic header to their firmware files
  • the boot count is not being reset upon boot, which means that even if it successfully boots openwrt upon next reboot it will fallback to the other partition

Note: this version has a hook to bridge both ethernet ports and enable DHCP on them upon first boot

New build for WHW03 v1 that works from factory.
Only tested that it flashes and boots OpenWRT.

Removed testing tools as well as hook to bridge ethernet ports.

@flipy @davideshay the build seems very stable so far, 5 days uptime, no glitches, no downtime, no problems so far.

The only erros I see on dmesg are related to the WiFi ath10k mod, they show up from time to time, this for the 11bgn radio:

[ 4095.368717] ath10k_ahb a000000.wifi: unsupported HTC service id: 1536
[ 4095.745111] ath10k_ahb a000000.wifi: Firmware lacks feature flag indicating a retry limit of > 2 is OK, requested limit: 4

And this one :

[ 4193.268999] ath10k_ahb a800000.wifi: Invalid VHT mcs 15 peer stats
[ 4274.701649] ath10k_ahb a800000.wifi: htt tx: fixing invalid VHT TX rate code 0xff
[ 4275.603288] ath10k_ahb a800000.wifi: wmi: fixing invalid VHT TX rate code 0xff

But this is not affecting the navigation, video conferences, etc, so maybe just a minor issue.

That's awesome @flipy, great work! Mine was properly installed and is working fine!

Just in case somebody else need it, I followed the procedure on https://www.linksys.com/us/support-article/?articleNum=274497 to upgrade the firmware and used the file openwrt-ipq40xx-generic-linksys_whw03-squashfs-factory.bin

I have configured the wifi interfaces, radio1/2, installed a couple packages, rebooted and everything was still there and working fine.

I couldnt get LuCi but assuming that's because of the difference between available packages/kernel and the branch your developing:

Collected errors:
 * satisfy_dependencies_for: Cannot satisfy the following dependencies for luci:
 * 	kernel (= 5.4.43-1-37761bfffe8b62214933bbf55c652828)
 * opkg_install_cmd: Cannot install package luci.

After one reboot, for some reason I lost access to the system and realized it was booting the original Linksys firmware again. Is there any way to get back to the openwrt I configured or do I need to reflash it with your firmware?

Just wondering what triggered it to boot the other partition.

Note: although install from factory and sysupgrade both work, I have not tested yet how to revert back to stock firmware.
Hence the recommendation is to always keep a Linksys firmware installed and work from there -- if doing an upgrade it will require to make a backup and restore afterwards.

Given that the bootcount it's not reset to 0 upon OpenWRT start, after some tries it will fallback to the other partition.
If you have serial access, the easiest way is to change U-Boot variable boot_part to the other partition.

I am working to rewrite the mtd reset_bc to work on the eMMC partition, but cannot give an ETA as of yet.

You could use the flag -F to force the installation, since the mismatch will not affect functionality.

Regarding issues, this one I've seen some references, I'll do some research.

New build for WHW03 V1.
Boot count will get reset to zero upon boot.
Added the possibility to check the current boot count by issuing mtd getbc_blk /dev/mmcblk0p12.
Also added LuCi to default image.

I'd recommend to revert back to stock before installing on the same partition, and then use sysupgrade to upgrade instead of flashing from factory.

To revert back to factory, here's the linksys code:

if [ "$BootPart" == "1" ]; then
                KERNEL_BLKDEV="mmcblk0p16"
                FIRMWARE_BLKDEV="mmcblk0p17"
        else
                KERNEL_BLKDEV="mmcblk0p14"
                FIRMWARE_BLKDEV="mmcblk0p15"
        fi

        Debug "Writing image: $FirmwareImage $KERNEL_BLKDEV .."

        dd if=$FirmwareImage of=/dev/$KERNEL_BLKDEV bs=4M count=1
        dd if=$FirmwareImage of=/dev/$FIRMWARE_BLKDEV bs=4M skip=2

Note: Looks like after a successful flash/upgrade, it won't change the boot partition and the previous version will be booted.
Also working into implementing the standard way to flash factory images on the device.
