@W3isserWolf seems to have disappeared.
Yes, I got it working. I was on a business trip, thatswhy i just tested it yesterday.
I've got several of these devices in use. Everything seems to work fine once the firmware is installed. However, I often encounter errors like the following during install:
Init commands:
Boot (PRI)-> fdt boardsetup;
ft_fixup_l2cache: FDT_ERR_NOTFOUND
Boot (PRI)-> fdt chosen;
WARNING: could not set bootargs FDT_ERR_NOSPACE.
Upgrade:
WARNING: could not set reg FDT_ERR_NOSPACE.
ft_fixup_cpu: FDT_ERR_NOSPACE
ft_fixup_l2cache: FDT_ERR_NOTFOUND
WARNING: could not set reg FDT_ERR_NOSPACE.
WARNING: could not set bootargs FDT_ERR_NOSPACE.
WARNING: could not set linux,stdout-path FDT_ERR_NOSPACE.
I'm able to get through the above by rebooting and/or repeating the process. Next time I'll keep better records of the hoops I jump through.
I am hitting the same issues as @nmpu - however I am not able to get through it by reflashing/rebooting. This appears to be a legitimate error. Could it be caused by a regression in the nightlies' FDT size, e.g. growth over time?
Here's my U-Boot blurb, maybe it can shed some light.

Ha, okay, figured it out. The second set of instructions on the wiki page have a longer boot_openwrt U-Boot var, with multiple attempts to resize the fdt:
setenv boot_openwrt "cp.b 0xEC000000 0x2000000 0x2000000; interrupts off; bootm start 0x2000000; bootm loados; fdt resize; fdt boardsetup; fdt resize; fdt boardsetup; fdt chosen; fdt resize; fdt chosen; bootm prep; bootm go;"
versus the step-by-step version, which doesn't work:
setenv boot_openwrt "cp.b 0xEC000000 0x2000000 0x2000000; interrupts off; bootm start 0x2000000; bootm loados; fdt resize; fdt boardsetup; fdt chosen; bootm prep; bootm go;"
Used the longer version, and saveenv again, and booted first try.
The longer version should only be needed if you're running an older version of OpenWrt, built before commit 1d06277.
What are you running? Seeing these come back is a bit worrying, the build should be padded well-enough not to have this issue.
The original issue is discussed here. Padding was resolved to have fixed that (though I didn't implement it properly the first time).
If you show me the image which fails to boot, I'll see if I can binwalk it and make sure the padding is working. If it is, we have a bug and should probably just document the "multiple resize" fix.
I have several more 'virgin' devices to FLASH. I'll keep better notes of exactly what I'm doing. I was a bit worried the first time I encountered the above because I thought maybe it had something to do with the stock firmware. The first time I encountered these errors, I just waited a few days assuming someone else would complain and it would just get fixed. Now I think it's just more about reboot/repetition.
Hi Everyone, I'm also having trouble flashing some "virgin" devices. I keep running into ft_fixup_cpu: FDT_ERR_NOSPACE errors. I'll paste a log of my terminal here so you can see. I've cleaned up the log a little due to post limits.

Hey @jpontius -- gah, that's really annoying. Sounds like u-boot is still picky about placement irrespective of fdt padding.
I have kernel 5.10.135 running just fine; maybe if we look at the different offsets we can suss out some pattern between fdt-1's Data Start location and whether it will boot.
For now, we have:
$ factor $((0x22f9228))
36672040: 2 2 2 5 41 59 379
Let me check 5.10.135.
Edit: 5.10.135 has it at 0x2f912c. Mod 4096 both of these are very close to the page boundary (0x2f912c -> 300, 0x2f9228 -> 552) -- but the failing one is FURTHER into the page, meaning that that there is probably no simple logic we can use to suss out what fdt blob addresses will and won't be bootable so we can adjust accordingly.
I guess one other thing we could try is to pad the kernel to a set length so the fdt is always at the same location with respect to the page ... but it's probably easier to just have users use more fdt resizes in-place, and when that starts breaking down to just provide a u-boot replacement.
Hey guys, I also have a ap3825i, now I successfully installed openwrt(BTW thank guys porting this device) now I have problem, I tried to run debootstrap to make a powerpc Debian root, and using chroot, but chroot said "Illegal instruction" , I tried to switch to other distro, like ubuntu 16.04, but chroot is still say that, is this kernel not support chroot? what should I do ?
Hey there -- try starting with an OpenWrt or Alpine Linux chroot. I'm gonna guess there are some compilation differences that have come up recently.

Yes, you are right, I'm try to chroot to /rom, and it's successed XD
Guys, I am trying the chroot Gentoo ppc musl, but there is still a problem with the "Illegal Instruction". "cat", "uname" commands can be executed normally, but "ping", "bash", "top" still prompts "Illegal Instruction", I am shown in the screenshot. What should I do?
Definitely look into the portage scripts for the binaries. Gentoo is probably using different compiler options. Can you share how you're doing this?
All - I am running into a curl error (132) when using ddns on a ws-ap3825i (using recent stable release 22.03). I have posted it here:
Any suggestions?
I've found that the time is basically always incorrect on first boot. There's some bug in sysntpd startup that I have not tracked down.
I will pull on that - so because the time is off, the cert generated at first boot by uhttpd uses the incorrect date/time, and then it is rejected when presented for the TLS handshake? (correct me where I am off here).
I have tried to regenerate the uhttpd cert with its defaults and use that for curl in ddns.
Not sure about DDNS' use of client-side certs, I thought DDNS only used the remote's cert.
I've also run into that ddns issue (with the ws-ap3825i, but it would surprise me if that's specific to this device). It broke in one of the later RCs. It did work at the beginning.
Thanks for confirming that. I am going to switch back to another head end router (TP-Link 4300) to get the ddns stable again. Will continue to monitor and experiment with using 3825 in the future.
I had switched my head end router to the 3825 to have a little more processing power with the two cores and more memory. Plus the wifi radios were not working / being detected by OpenWRT on this particular AP out of the lot that I bought.
