Problem booting Linksys EA4500 with Linux Kernel 4.11.3 Kirkwood

Hey bodhi! Thanks as always for the updates. I'm playing with the EA4500 again, wanted to see if DSA is perhaps working in a newer kernel, but boot gets stuck here (with both .dtb files, with DSA and without):

Uncompressing Linux... done, booting the kernel.

Any ideas? The 4.4 kernel bundled with the rootfs works fine...

When it get stuck here, you should turn on earlyprintk in bootargs. Add this to your u-boot env bootargs. If not sure, post your u-boot envs listing in serial console, or in Debian here and I'll help.

earlyprintk=serial

Thanks for that, handy trick!
Here's the output. The only thing I've changed is updated the kernel, which I've done 100 times on the EA4500 and the Dockstar without problems. Might it be an issue with 4.11.3? I can try an earlier version if you'd like?
Using the non-DSA dtb.

megal0maniac,

It looks like the Non-DSA DTB that you've appended to the kernel image has some problem.

Try remake the uImage with this DTB that should be newly compiled with this kernel?

I'm 99% sure that I'm using the dtb packaged with the 4.11.3 kernel package (assuming that tar -cvf file.tgz overwrites by default)
I'll check again but I don't think that is the problem...

megal0maniac,

Can you boot older kernel with the same DTB?

I agree, I followed the instruction for 4.11.3 but failed to boot.

however, 4.9 works ok

megal0maniac,

You have following error in log:
[ 0.466636] Unpacking initramfs...
[ 0.470107] Initramfs unpacking failed: junk in compressed archive

This means that there are memory overlap between kernel and initramfs.
You need to allow more space for the kernel and load initramfs at higher address, not at 0x1100000, but for example at 0x1200000.

Right, beware of stock u-boot does bad things to memory. It does not relocate the images correctly (if at all).

In this case, the kernel is small enough to fit in the range of 0x800000 to 0x1100000. I need to look at the entire boot log to tell if the uInitrd is just bad.

Turns out that the kernel is too big with embedded dtb. Loading uinitrd to 0x1200000 worked fine :)
Too bad I'm stuck with this dumb stock u-boot. Thanks for the help!

megal0maniac,

Have you tried this DTS for the Linksys EA4500 with updated DSA binding? This has been updated in Jan 2017.

How sneaky, I didn't even notice that "viper" was there - I just tried "ea4500" and "ea4500-dsa"
This looks promising (and new):

And it works! :)
Was able to configure interface "ethernet3", bring it up and ssh into the router over it. Awesome!

Awesome :) thanks for testing!

I did not notice this DTS either until wacke had problem in the Qizitong thread because of the new driver. It inspires me to think it is time for me to look into this u-boot again. My box has been collecting dust for a while :)

So you just connected the ethernet cable to port 3? or is it port 2?

The interface names correlate to what's on the back of the router (internet & ethernet{1..4})
I just did

ifconfig ethernet3 10.0.0.1/16
ifconfig ethernet3 up

and it worked. When I plugged the cable in and the link lights came on, I got kernel messages about link up and negotiated speed - exactly like you'd expect with a directly connected interface :)
I'm not actively using the router so I can't check for stability, but my quick tests proved it to be functional at least.

megal0maniac,

Yes, it works fine for me too. I've cloned it to the latest kirkwood-ea450.dts and made some cosmetic changes. So far it has been up running for a couple hours.

One minor problem is the buttons are not working (they were fine before in previous version).

I'll post the DTB in the Debian Linksys EA4500 thread.
