its such ass when you're doing a bisect and the damned board waits until *just after* you issue git bisect bad to show signs of life xD

I am trying to get alpine linux to boot on a turris omnia (armv7, onboard u-boot) but u-boot gets stuck at `Starting kernel ...`. Any pointers on how to debug this?

<mps>
pinsl: looks like u-boot works but something is wrong with kernel
<hanetzer>
does the alpine-lts kernel config include the stuff the turris need? clock controllers and stuff like that are very important.
<hanetzer>
I'm assuming the vmlinuz-lts file is a zImage?
<pinsl>
hmm, well alpine does not include the boards dtb file
<pinsl>
yes, `file` tells me its a zImage
<mps>
pinsl: could you try with linux-edge instead of -lts
<hanetzer>
yeh. that could be an indication they don't flip their CONFIG_* options, because generally that'll cause the dtbs to be built as well. maybe try an archlinux arm boot, setup alpine using the rootfs image or so, and build a kernel with those options flipped on
<mps>
pinsl: if you could test linux-edge and see something wrong I will look to fix (I'm maintainer). would be nice to know if alpine works 'out-of-the-box' on turris
<pinsl>
mps: on it :)
<hanetzer>
mps: oh hey. you're a maintainer? I'd like some help wrt to fixing up another alwinner board (sunxi-s3, on the pine64 pinecube) for use with alpine.
<mps>
haritz: np, just report what is needed
<mps>
uh, sorry haritz I meant hanetzer
<hanetzer>
hehe. wrong ha, but sure. problem is there's only one 'big' boot media for those, and that's the sdcard, so I'm unsure how I can boot alpine and install it using that tbh
<mps>
hanetzer: I usually use scripts on workstation, inserting usb/sdcard and installing all needed on workstations
<pinsl>
the current openwrt image for the omnia has Linux 5.10.138
<pinsl>
I assume this is a useful commit: https://git.openwrt.org/?p=openwrt/openwrt.git;a=commit;h=9f3f61a0d968fbe7b93899f948f3c34612683ba6
<mps>
will look
<pinsl>
thanks :)
<mps>
pinsl: if you are ready to test changes and report back I could try to build linux-edge for you
<mps>
ofc, it if it works push it to alpine
<hanetzer>
pinsl: try perhaps repacking the alpine media with debian kmods/kernel/dtbs and see if that works. Its most definitely kernel config options, there's nothing particularly fancy about alpine's userspace
<mps>
and I see I didn't enabled u-boot for turris machine on alpine. nobody asked
<pinsl>
mps: ready :)
<pinsl>
hanetzer: I am using the dtb file from openwrt
<mps>
hanetzer: right, I sometimes used debian or arch linux kernels with alpine to test some things
<pinsl>
mps: the board has onboard u-boot on spi-flash
<mps>
pinsl: ah, that explains why no one asked for it
<mps>
pinsl: on u-boot line `setenv bootargs earlyprintk console=ttyS0,115200 modules=loop,squashfs,sd-mod,usb-storage` maybe adding `loglevel=7` could say something
<pinsl>
mps: no...
<mps>
maybe you could uncompress vmlinuz and try with it, not sure if their u-boot uncompress kernel after load
<pinsl>
the debian kernel that boots also is a zImage
<pinsl>
how would I go about uncompressing it?
<mps>
ah, ok then
<mps>
if it load and uncompress debian kernel it should also alpine ones
<mps>
pinsl: could you send or paste somewhere debian kernel config
<pinsl>
the board has U-Boot 2019.07 but I also tried once with U-Boot 2022.10-rc4

I am struggling to find the debian kernel config
<mps>
does /proc/configs.gz file exits
<mps>
maybe modprobe configs before look at this file
<pinsl>
ah got it
<pinsl>
I don't have a running debian system
<mps>
I forgot where to look for config on debian
<mps>
maybe in /boot dir
<hanetzer>
sjg1: when you get a chance to look at this: is there a mechanism I can use to build an old chromeos? Mostly interested in trying 'stock' chromeos with USE=fwconsole/similar against servod to see if its u-boot that's doing the weird input-only over cpu_uart_pty
lucascastro has quit [Remote host closed the connection]
<hanetzer>
sjg1: nah, would be fun tho. also you may find this fun. just added the equivalent of linux's rockchip.usb_uart to rk3288 (easy enough; same as rk3188 but different bit fiddling)
