Apr 17 08:26:08 <owrt-snap-builds> Build [#54](https://buildbot.openwrt.org/master/images/#builders/64/builds/54) of `realtek/generic` failed.
Apr 17 12:09:26 <stintel> hurricos: thanks for the info, I will check that oct-pci-boot out
Apr 17 12:09:53 <stintel> too bad I got those without 1GiB NAND
Apr 17 17:04:59 <stintel> hurricos: geez first attemtps to do something with that SDK ... yikes
Apr 17 17:53:29 <Spyro1248> Hey folks
Apr 17 17:53:56 <Spyro1248> I'm attempting to build the homehub3 image but its failing to build the kernel image fully
Apr 17 17:54:11 <Spyro1248> (complains the .bin file is too large)
Apr 17 18:03:22 <Spyro1248> the build appears to have built an initramfs+kernel .bin file, but not a standalone kernel image
Apr 17 18:04:09 <Spyro1248> where can I find the kernel its building, and how do I trigger a rebuild? (Im not familiar with the build system
Apr 17 18:23:59 <Spyro1248> no-one about?
Apr 17 19:12:52 <Spyro1248> no buildsystem guru about today?
Apr 17 19:24:14 <PaulFertser> Spyro1248: the kernel is built in build_dir/target*/linux*/linux*/
Apr 17 19:26:46 <PaulFertser> Spyro1248: plain "make" should be enough to rebuild whatever you changed in there
Apr 17 19:27:28 <Spyro1248> PaulFertser: hi :)
Apr 17 19:28:15 <Spyro1248> PaulFertser: I think I may have had some issue with serial - I've just tried pasting the initial few lines of the u-boot image I found online, and it actually responded with * characters. no idea why its behaving differently...
Apr 17 19:29:14 <Spyro1248> huh... and now its actually "working" (assuming the u-boot image is good)
Apr 17 19:29:38 <Spyro1248> holy shit, I'm in :)
Apr 17 19:29:45 <PaulFertser> Spyro1248: probably the ground connection was unreliable
Apr 17 19:30:03 <PaulFertser> Spyro1248: so you booted your self-compiled u-boot on the target after loading it via serial ROM bootloader? Cool!
Apr 17 19:30:06 <Spyro1248> PaulFertser: possibly, although I can't see why - waveforms looked fine on the scope etc.
Apr 17 19:30:21 <Spyro1248> Its not my u-boot - but it worked...
Apr 17 19:30:44 <Spyro1248> I *should* be able to follow the HH3.0 instructions to flash an image now...
Apr 17 19:37:40 <Spyro1248> hm. no network. bummer.
Apr 17 19:38:41 <Spyro1248> lets try the WAN port :)
Apr 17 19:42:38 <Spyro1248> aha! dhcp worked...
Apr 17 19:54:29 <Spyro1248> install kernel booted! getting somewhere!
Apr 17 19:56:36 <Spyro1248> ok, pingable, loginable environment on the router...
Apr 17 19:56:39 <Spyro1248> now what...
Apr 17 20:18:04 <Spyro1248> hmm. no mtd-utils in the base image...
Apr 17 20:18:06 <Spyro1248> annoying.
Apr 17 20:18:24 <Spyro1248> some tool called "mtd" though
Apr 17 20:19:01 <PaulFertser> Spyro1248: yes, OpenWrt uses custom "mtd" tool to handle all the usual usecases
Apr 17 20:19:10 <shibboleth> Spyro1248, oh, that's for brewing coffee
Apr 17 20:19:24 <PaulFertser> Spyro1248: it's supposed that once you boot initramfs image you can just use "sysupgrade" and regular "sysupgrade" image to flash.
Apr 17 20:19:36 <Spyro1248> PaulFertser: isnt "backing up the original NAND" considered a usual case?
Apr 17 20:19:50 <Spyro1248> PaulFertser: I will do that, but I have no backup image yet
Apr 17 20:20:32 <Spyro1248> PaulFertser: Im looking for something like nanddump
Apr 17 20:21:08 <PaulFertser> Spyro1248: hm, you can install additional packages with "opkd" if you need that, works on initramfs too.
Apr 17 20:21:29 <Spyro1248> Ive tried that, but there doesnt appear to be a mtd-utils package?
Apr 17 20:22:01 <Spyro1248> aaahhhh, is it nand-utils?
Apr 17 20:22:57 <Spyro1248> yes, yes it is...
Apr 17 20:23:22 <PaulFertser> Spyro1248: yes, I just did "git grep nanddump" in the OpenWrt git repo and saw the makefile and took a peek inside and nand-utils were there
Apr 17 20:24:19 <Spyro1248> right, now I just have to remember how nanddump works (its been almost 20 years...)
Apr 17 20:35:38 <Spyro1248> I guess I can just dump the mtdblock* devices really...
Apr 17 20:36:02 <Spyro1248> I found a neat trick actually...
Apr 17 20:36:25 <Spyro1248> now that I'm booted, I can just remove silent=1 from the u-boot config in /dev/mtdblock2
Apr 17 20:39:45 <Spyro1248> ok, mtdblock5 has errors and is not dumpable that way (presumably needs dumping with the ubi tools, but I dont really care about whats in it...
Apr 17 21:48:37 <Spyro1248> AHA! I have unlocked u-boot on the BT Businesshub 3.0
Apr 17 21:49:41 <Spyro1248> This file is a u-boot that can be serial downloaded to the device: https://sourceforge.net/projects/hh2b4ever/files/uboot%20for%20v3a/u-boot.asc/download
Apr 17 21:56:11 <PaulFertser> Spyro1248: do you already have an OpenWrt wiki account to document the procedure?
Apr 17 21:58:40 <Spyro1248> PaulFertser: I do not. I would like one...
Apr 17 21:58:53 <PaulFertser> Spyro1248: please send me your desired wiki nick and e-mail.
Apr 17 22:23:58 <Spyro1248> Ooooh, so close... I can run the sysupgrade, but it fails.
Apr 17 22:30:18 <PaulFertser> Probably the ubi names do not match or something like that
Apr 17 22:30:41 <PaulFertser> volume names I mean
Apr 17 22:32:09 <Spyro1248> I think its the bootloader...
Apr 17 22:32:21 <Spyro1248> the partitioning looks... wrong.
Apr 17 22:32:44 <Spyro1248> I wonder if the serial bootloader will boot from my nand, its env is rather different
Apr 17 22:33:12 <PaulFertser> Do you mean sysupgrade worked but booting failed?
Apr 17 22:38:28 <Spyro1248> yes
Apr 17 22:39:04 <PaulFertser> Probably it's just the bootenv that needs tweaking a bit.
Apr 17 22:39:15 <Spyro1248> PaulFertser: yeah, I expect so
Apr 17 22:43:01 <Spyro1248> looks like shes a winner...
Apr 17 22:43:13 <Spyro1248> OpenWrt 19.07.7, r11306-c4a6851c72
Apr 17 22:43:39 <Spyro1248> I'll just go and make those changes to the uboot env permanent...
Apr 17 22:45:17 <PaulFertser> Spyro1248: congrats :)
Apr 17 22:47:37 <Spyro1248> Yep, direct boot from nand, all working! :)
Apr 17 22:47:53 <Spyro1248> I'll write that up tomorrow, after I've had a bit of a play and made sure everything works.
Apr 17 22:54:38 <Spyro1248> Hmmm. no wifi...
Apr 17 22:54:41 <Spyro1248> seems suspect.
Apr 17 23:05:05 <PaulFertser> Spyro1248: ath9k needs calibration data
Apr 17 23:05:22 <PaulFertser> Spyro1248: or if it's not detected at all, owl-loader to fix the pci pid.
Apr 17 23:05:42 <Spyro1248> ah, thats most likeley - whats owl ?
Apr 17 23:06:39 <Spyro1248> hm. owl-laoder is loaded.
Apr 17 23:06:56 <PaulFertser> Spyro1248: check dmesg to see whether it's wrong pid or lack of calibration data
Apr 17 23:07:00 <Spyro1248> aha - owl loader complained in the log about calib data
Apr 17 23:07:17 <Spyro1248> right, so I need to work out how to feed it that...
Apr 17 23:08:19 <PaulFertser> Spyro1248: check /etc/hotplug.d/firmware/10-ath9k-eeprom
Apr 17 23:08:54 <PaulFertser> Or 12-eeprom
Apr 17 23:09:40 <PaulFertser> Spyro1248: apparently you're supposed to have a partition called art-copy
Apr 17 23:19:39 <Spyro1248> PaulFertser: I do have one named that, but its blank (even in my backup)
Apr 17 23:21:29 <pkgadd> Spyro1248: in general lantiq older than vr9 (xrx2xx) is seeing very little usage and testing, so you're likely to be the first to use it in quite a while
Apr 17 23:22:05 <PaulFertser> Spyro1248: then you should try finding that art data in the other partitions.
Apr 17 23:22:11 <Spyro1248> indeed
Apr 17 23:22:22 <Spyro1248> I wonder if its got the board name wrong (doubtful)
Apr 17 23:24:03 <Spyro1248> board name looks reasonable
Apr 17 23:38:33 <Spyro1248> Weird.
Apr 17 23:38:56 <Spyro1248> Looks like the businesshub 3.0 doesnt keep the calib. data in art-copy
Apr 17 23:39:08 <Spyro1248> will have to look in the main filesystem (what a pain)
Apr 18 00:20:46 <Spyro1248> I dont suppose anyone here is running a HomeHub 3 ?
Apr 18 00:21:12 <Spyro1248> If so, I'd really appreciate a copy of the /dev/mtdblock2 partition
Apr 18 00:21:41 <Spyro1248> I can't seem to restore my mtd backup :(
Apr 18 00:29:46 <Spyro1248> Bollocks to it. Just bought a spare one so I can see where this went wrong.
Apr 18 00:29:51 <Spyro1248> (maybe recover this one)
Apr 18 00:30:29 <Spyro1248> PaulFertser: I'll hold off updating anything online until I've got an idea what went wrong here.
Apr 18 00:30:47 <Spyro1248> I could *swear* I saw wifi interfaces up at one point in this process...
Apr 18 00:31:09 <Spyro1248> this time I'm going to make sure I have a good nand dump :)
Apr 18 00:36:00 <pkgadd> The BT HH5A tends to be dirt cheap in the UK as well - and is much better hardware
Apr 18 00:39:54 <Spyro1248> pkgadd: I am using two of them here :)
Apr 18 00:40:16 <Spyro1248> pkgadd: its a matter of priciple... the BT Businesshub is going to give up its secrets :)
Apr 18 00:41:48 <Spyro1248> In the meantime, I guess I'll have to lend my neighbours one of my hh5a devices :)
Apr 18 00:46:58 <pkgadd> hehe
