stintel: I've found squashfs with xz and arm BCJ always dies in the same way you're seeing. xz without BCJ I have no problems
<russm>
haven't bothered digging to see what the actual problem is, mainly use zstd these days

slh / slh64 (?): Thanks! And pardon the lack of heads up, I'd have poked you about the NBG6817 MMC PR earlier, I've just had to withdraw from real-time chat as unrelated life stuff's been overwhelming. I'm glad stuff seems to be working, or at least nobody's yelled at me on GitHub/etc for breaking ipq806x yet :)
<slh>
digitalcircuit: don't worry, sadly I didn't find time this weekend to test it on my device yet (hopefully qca8k/ dsa gets merged 'soon', taking juggling that patch series from my plate; switching between mildly complex swconfig vs dsa configs isn't fun...)
<digitalcircuit>

russm: I tried with !XZ but seems like something didn't work as expected ... during mksquashfs perf showed zstd compress and the kernel still tried XZ
<stintel>
need to further investigate

ahh, there is an exception for arm and powerpc already to not use BCJ, I'll just add powerpc to that

hmmm actually, that uses KARCH which for ppc32 and ppc64 is powerpc so it should already not be using BCJ
<stintel>
hmm, wait, I'm probably misreading that :)

yeah, I read it wrong, it does the opposite, it enables bcj for ppc

blocktrron: hm ok, the reason I'm asking is that I'll have a 7520 soon. It's the same hardware as 7530 with some artificial restriction on the vendor firmware
<dhewg>
it does have a different revision (247) and now I wonder if I need to add support for it because the initial avm bootloader checks that or if I can just use a 7530 uboot
srslypascal has joined #openwrt-devel
<blocktrron>
If it does not find the correct revision, it uses the first one
<blocktrron>
Nur the dt does not Matter for us anyway
rua has quit [Quit: Leaving.]
<blocktrron>
What is probably still there is the limitation on 100 Mbit/s on the LAN ports in case it is already set by the bootloader
<blocktrron>
ar40xx afaik does not touch the port speed configuration
<dhewg>
k, I'll validate that once I get the device
<blocktrron>
Could be that my assumption is wrong (now that i think about it), as we load our own U-Boot in second stage.
<blocktrron>
This was just a thought that sticked to me when observing different FC configuration between ipq40xx boards
<dhewg>
fwiw I came up with this patch http://sprunge.us/Q7r2QD but as I don't have the hw yet it's completely untested
<dhewg>
(if that makes sense and works the uboot patch obv should go in its repo instead of a patch file here)
<blocktrron>
dhewg: if U-Boot works, i would just stick with using the 7530 one
<dhewg>
alright
<blocktrron>
The OpenWrt image for the 7520 however should be kept
<dhewg>
if I flash the 7530 uboot, and it doesn't work, it won't brick my device, right? ;)
<blocktrron>
in case we realize we need to differentiate between both boards.
<blocktrron>
dhewg: check NAND part layout in vendor firmware and if it matches you are good to go
<dhewg>
alright, thanks
<blocktrron>
What is still dislike is the inflexibility of the current buildsystem regarding multi-dtb FIT images
<dhewg>
I found the corresponding TODO :)
<blocktrron>
I'd love to just have a single kernel image for all boards where we need to spin our own u-boot anyways
<blocktrron>
But that's just rambling about stuff, nevermind
<dhewg>
btw, do you have an url or something where the boot process is descibed in detail for avm devices? So far I only found bits here and there on forums

jow: will take a look
<blocktrron>
dhewg: regarding installation or for the regular bootchain?
<blocktrron>
regular bootchain is PBL --> SBL --> EVA --> openwrt-uboot --> linux
<blocktrron>
What is important to note here: At least their post-4040 models have a signed chain up to EVA
<dhewg>
yeah, I meant the regular
<blocktrron>
EVA is 2x on the NAND and PBL will boot the one with a valid signature (and no one if both are corrupt / unsigned)
<blocktrron>
The reason for this probably being they update the bootloader OTA

oh, actually, not that bad

it happens in /etc/init.d/done

it's simply the call "mount_root done"

so reproducing it is very easy

dhewg: there are many who force-flash the 7530 OEM image on the 7520, to get rid of the 100 MBit/s port restriction, it's purely done in their firmware
