Thanks, I'm using the original firmware until you find a solution to the performance problems.
However, this command :
dd if=/tmp/FW_WHW03_2.1.13.200506_prod.img of=/dev/mmcblk0p14 bs=4M count=1
return
dd: error writing '/dev/mmcblk0p14': No space left on device
1+0 records in
0+0 records out
Looks like I made a mistake in my previous post.
Was that run from an installed OpenWRT partition or from an initramfs?
If the former, try to write to mmcblk0p16 and mmcblk0p17, which correspond to the boot_part 2 firmware location.
Same problems with mmcblk0p16 and mmcblk0p17.
I try from an installed OpenWRT boot_part 1.
I don't really see how I can be more useful, because when I make an ls -la /dev or with df, I don't see anything starting with mmc*, which is normal I guess.
I'm connected in serial on it, so if you have a more radical way requiring it, it's possible.
Is your model a V1?
The label clearly indicates version 2

Here is a list of steps to flash a factory image into a V2 model:
fw_printenv boot_part.cat /sys/class/ubi/ubi0_0/device/mtd_num
FIRMWARE_IMAGE=/tmp/FW_WHW03_2.1.13.200506_prod.img
mtd erase $FIRMWARE_BLKDEVmtd write $FIRMWARE_IMAGE $FIRMWARE_BLKDEVmtd erase $KERNEL_BLKDEVmtd write $FIRMWARE_IMAGE $KERNEL_BLKDEV
I have tested that this steps successfully work but I have not tested booting from the factory image due to not having spare devices to do so.
I do apologize if my lack of availability has impacted you.
UPDATE: To manually flash a firmware you should load the CA Support page of the Linksys Factory Firmware: http:///ui/1.0.99.192419/dynamic/home.html#casupport
Thanks @flipy, this procedure worked for me.
I do apologize if my lack of availability has impacted you.
No problem, don't worry.
If you need someone to test future builds when you will have a little more time, do not hesitate
I'm really interested in getting this firmware working. I've cloned @flipy git repo and built an image, but it will not boot on my WHW03v2.
The binary firmwares that @flipy posted here are no longer available to download. The links have expired. If anyone (@Pro_info ?) has a copy of the firmware and can repost it, this would really help.
Thanks
No, I didn't keep the compiled binaries.
Did you clone the whw03v2 branch and not the master branch?
I will make a new build for both versions with an updated upstream tree.
I'll keep you posted.
BTW, is there any package you'll like to see included, besides LuCi?
I did clone the v2 branch, and I tried the 19.07 variant too. I guess there could be a problem with my build system, but the same system produces viable firmwares for the EA/MR8300.
Luci is all I really need thanks. I'm very keen to get this working, and I'm happy to work through the performance issues.
Thanks a lot for your help, and for the effort you've put into this.
I have added a new build for WHW03 v2: https://github.com/flipy/openwrt/releases/tag/v0.0.1
I will be able to test it during the weekend, and expect a new release for WHW03 v1 as well.
Thanks for your quick work.
I've given this a try, but just like the firmware I build myself from your sources, it wouldn't boot.
I'm running the official firmware version 2.1.8.192419, and the web interface confirms my model number as WHW03v2.
I'm using the /fwupdate.html page to install your firmware (openwrt-ipq40xx-generic-linksys_whw03v2-squashfs-factory.bin). After I get the "OK" response, the LED remains purple, and after 5 minutes of no ping responses, I then power-cycled it. The LED then goes to solid blue and stays that way. I left it for over 5 minutes, but there was no change.
I'm wondering if the problem I'm experiencing exists only in the ".factory" version of the firmware. That could explain how these firmware work for you, assuming you install the ".sysupgrade" variants when testing.
I don't have a serial cable attached, so I'm afraid I can't give any more information at this time.
Here is the console output. Seems to die very early on.

Interesting, thanks for the output.
Looks like it is able to identify the NAND chip but it has some issues accessing it.
I'll debug and give it a go on my devices.
I'm new to the build process though have built drivers and fought the Linux kernel, switches and PHYs in the past but where is the config, presumably a file called .config, used to build your v0.0.1 ?
Just uploaded version 0.0.2 for WHW03 V2, not tested yet.
Any feedback more than welcomed!
