Hi ggsn
Have you been able to solve this issue? I'm getting exactly the same errors, my board only works if I stop u-boot and use bootipq manually.
Which IPQ4019 device? What bootargs are passed? What does the kernel need?
Vague questions will usually get vague answers at best.
For that matter, a word-for-word repetition by a “different” user who just joined is rather suspicious.

Where did you get the firmware? Can you please try this one: https://megaupload.nz/B4m66cw8b1/openwrt-ipq40xx-compex_wpj419-squashfs-sysupgrade_bin
solve this issue? me too .
I have same issue on compex wpj428. Is there some fix pending or should I dig in? Thanks.
Are you (all) using Compex-supplied firmware or OpenWrt itself?
If Compex-supplied, then they would be the ones to ask. Very often OEM firmware uses bits and pieces (or huge swaths) of the OpenWrt OS, but then combines it with one or more of vendor kernels, proprietary drivers, vendor tool chains, ...
Looks like a problem with the DTS or one of the drivers from the boot log. Perhaps I'm missing it, but I don't see the "419" in https://openwrt.org/toh/compex/start
At least on master there is target/linux/ipq40xx/files-4.14/arch/arm/boot/dts/qcom-ipq4028-wpj428.dts, which may provide insight into what I would hope is a running version of OpenWrt on a Compex / IPQ40xx platform.
The bug is probably because the bootloader does not reset the PHY during normal boot process.
You may need the PHY reset patch in my post and specify the reset pin in DTS.

I'm using Compex wpj428 and hit same issue. I can took kernel patch but I'm not sure which phy-reset-gpio should be used for my board (as don't have schematics). Ideas? Thanks.
Hi, FYI
on WPJ419 the phy-reset-gpio is GPIO#47 and on WPJ428 is GPIO#59

Note that if you're using 4.14 kernel, you must replace patches-4.19 with patches-4.14 in the patch
Yes. I'll try to refresh patches on top of latest master and then post for review + test on device. One other issue I'm facing is thta when usb modem is plugged to M2 connector is not recognized (while when connected via extender board to USb then it works). I assume M2 usb is not working or something like that but that's different story :).
I've tried to reuse existing patch and apply to 4.14 kernel. Basically I took only patch with add support for phy-reset-gpio + add change in dts for compex 428 but issue is still present. Anything else should be fixed or taken from patch (patch add support for other boards also so I drop that + some other stuff which is IMO not relevant). Commit can be found here
Also I was poking it yesterday and fixed crash issue with following hack:

IMO looks like mii_bus driver not yet probed and priv->mii_bus->dev is NULL and thus crash. AMybe proper fix would be to return -EPROBE_DEFFER but I'm unsure. Any ideas?
I don't think the Ethernet can work using this modification, it just a work around to pass over Kernel Panic.
Yes I know but ethernet works. I was able to connect to device without issue and avoid crash.
No you're right. Interface is up but I cannot get dhcp. So any ideas why original patch won't work? Maybe it's pin number wrong? Thx.
I found that Compex has their own repository here, I think you should try it.

@oldme thanks a lot. Looks like that in this repo they have phy fix already included. I'll overtook and post patch. Thank again.
