yes, mount and copy to USB or scp from it ?
a usb drive will usually appear as sda1.
mount /dev/sda1 /mnt

This is crazy, i'm not able to build IPK file for a single package.
And found many forum posts complaining about this but no solution 
Apparently, wiki is obsolete in this regard.
Still not able to build nand-utils separately at all.
This doesn't work
I think i got it now.
compile also installs the IPK of a package into bin.

Testing my trust level.
Ah nice! Ok, I can reply again. This was 30 minutes wasted on trying to figure out a way to get around the limitation of my trust level.
Got it and done.
Next issue please.
Seems to work.

How to build nand-utils.
First select it in the menuconfig.
Then do this:
make V=s -j$(($(nproc)+1)) package/utils/mtd-utils/clean
make V=s -j$(($(nproc)+1)) package/utils/mtd-utils/compile
ls -l bin/targets/alpine/generic/packages/nand-utils*.ipk
It booted fine..... but DHCP leaked.
Luci is up and reconnecting the ethernet cable resulted in expected DHCP address.
First step is success then. Not done yet.
We didn't remove switch setup from u-boot env yet. Now the next step.
We need to modify this line:
bootcmd nmrp;run check_dni_image;run bootargsnand;qca8337_init_one; ledtoggle;sleep 1;run bootnand
And remove qca8337_init_one.
The line becomes this:
bootcmd nmrp;run check_dni_image;run bootargsnand;ledtoggle;sleep 1;run bootnand
Use this:
fw_setenv bootcmd 'nmrp;run check_dni_image;run bootargsnand; ledtoggle;sleep 1;run bootnand'
Then verify with fw_printenv that qca8337_init_one is not present within bootcmd.
After that command the line ended up at the bottom. Is that ok?

yes, that's normal after an update.
Reboot time I assume?
Yeah, I'm going for it!
Edit: No change. DHCP still leaked. Reconnecting ethernet again resolved it.

Ok, then this was not the reason. I suspect that u-boot enables switches before even booting OpenWRT because it needs Ethernet for NMRP.
Would be great if you could stop your device in u-boot and then check whether DHCP still leaks.
We could also temporarily remove nmrp from bootcmd and test. After the test, you can add it again now that your uboot env changing works on OpenWRT 
And for that I need to cable.
I'll see what I need for making one tomorrow.
Thank you.

Ah yes, nmrp could perhaps be causing this.
But I am not too convinced for one reason.
When the router boots I can see first one DHCP leak for a short period of time, I assume this to be nmrp. It only lasts for about 1 second or so then the ethernet cable disconnects and DHCP lease resets.
Then it takes much longer for the next leak to come and this time it is permanent until the lease expires.
hmm, this is a good hint. my guess is then that it takes very long between switch activation by openwrt driver and switch setup from /etc/config/network. maybe i could setup switch in such a way that is disabled until the config is applied, somehow.
i‘ll test it on my device and if i have something worked out, will report here.

I timed it.
About 15 seconds after power on the first leak comes. It lasted for about 5 seconds and then the cable disconnected.
15 seconds later the ethernet reconnected and next leak came (35 seconds after power on) and is semi-permanent.
ok, sounds then like openwrt is to blame here then. i‘ll see whether i can get the desired behavior by modifying initial switch register configuration. it seems doable but i need to test.
but at least we know now that changing uboot env on nand is working. thanks for testing that. will be useful for other things later on.

PORT*_LOOKUP_CTRL switch register looks interesting. We can completely disable a port with this. Will test it. Hopefully switch setup done by OpenWrt will enable it again.
Another option we have is this. Why not setup your switch the way you need it right away when switch driver is loaded. It‘s a bit hacky but would solve your problem i think. Then there will be no period of time where it is configured differently. This is possible because we can configure VLANs directly with registers as well, w/o waiting for openwrt to do the job.
