@eanbowman (๐ข๐ธ๐ฏ๐ฝ๐ท๐ฎ๐ผ๐ผ Guaranteed ๐ฆ๐ WFH): Oh fun... The kernel they released in 2013 has no `pv` command, but the provided https://t.co/mEfxzZ5Aas has it in the `dd` command. Remove "pv |" and it seems to actually update. 13 minutes to write armbian. Good thing the serial terminal is up so I can see a log in case... (24s ago)

@eanbowman (๐ข๐ธ๐ฏ๐ฝ๐ท๐ฎ๐ผ๐ผ Guaranteed ๐ฆ๐ WFH): Maybe that armbian image is too big. I'll try the Ubuntu image from 2013 they suggest. https://t.co/UztUVNMYpK (18s ago)

hello.. if my raspberry pi 3b+ supports USB boot. Can i simply load Armbian on USB and boot from that?

abananabread: nope
<lanefu>
all these little cheap single board computers don't have bioses, or UEFI.. which means each board requires a custom bootloader configuration
<lanefu>
its the same reason you can't just download plain arm ubuntu and install it on rpi.. you have to use hte special image
<sbbg>
I don't get it. I didn't change any settings in Kernel. I don't think it's happen because of missing FS support.
<sbbg>
yet I can confirm it's happening to LibreELEC with 5.6 kernel. ( No wifi/ethernet )

5 heatsinks and a fan later now my little nano pi neo plus 2 has a 5.6.5 custom kernel on it that was compiled "on" it after I built one using the ubuntu vm
<lanefu>
haha awesome
<lanefu>
how long did it take to build the kernel from the neo
<Tenkawa>
now its time to start doing battery tests
<Tenkawa>
it took a fair bit of time
<Tenkawa>
a few hours
<Tenkawa>
I unfortunately didnt think to set up my normal timers and was watching movies so I didnt get a good representation
<lanefu>
hehe
<Tenkawa>
I'm going to get one of my 5v batteries now and see how much runtim I get instead of running it off my usb 3
<Tenkawa>
(I have a 5A and a 10A pack to test)
<lanefu>
Oooh that'll be good
<HerculeP>
just measure the drawn current and do some maths
<Tenkawa>
eeeek maths
<Tenkawa>
(math is my weakness)
<HerculeP>
not real maths, just multiply ;)
<lanefu>
effort is my weakness
<Tenkawa>
haahaa
<Tenkawa>
lanefu: that was good
<lanefu>
i wish it was less true lol
<Tenkawa>
oh good.. the pack is even charged lol
<Tenkawa>
oh yeah.. this thing is running a m.2 root too now lol

ok.. battery experiment has begun
<HerculeP>
if the SBC is getting pretty warm it means high input current and the battery won't last very long
<HerculeP>
maybe five hours?
<Tenkawa>
which sbc?
<Tenkawa>
these all seem to get pretty hot
<Tenkawa>
(the nanos)
<Tenkawa>
I bolted 5 heatsinks and a fan on mine
BCMM has joined #armbian
<Tenkawa>
I'm going to test out a clang build to see if it can compile things any cooler
<Tenkawa>
hmm at least in my testing its running quite a bit cooler
<Tenkawa>
than compiling with gcc
<Tenkawa>
interesting
BCMM has quit [Read error: Connection reset by peer]
<Tenkawa>
lanefu: I'm running it on -j6 now and last night with gcc 9 it was easily hitting 83C, with clang 9 it is averaging 61C
<Tenkawa>
i did take a few more debug flags out which might be affecting it but I doubt it would do "that" much
<R0b0t1`>
IgorPec: well, I want to create a bootable / for my board based on the armbian config, but use debootstrap and avoid Vagrant to make reproducible builds
<R0b0t1`>
which sbc with m.2 btw
<R0b0t1`>
interested
<Tenkawa>
the nano pi neo plus 2 (just usb connected)
<Tenkawa>
but since they are both tiny I figured.. why not
<R0b0t1`>
IgorPec: I did find the configs, that may be enough, but tracking down how they are used exactly is taking some time, so if that is documented I would appreciate link
<R0b0t1`>
@ anyone else too
<Tenkawa>
what you trying to do ?
<lanefu>
Tenkawa: this probably won't make a difference.. but i like the schedutil governor... `cpufreq-set -g schedutil`
<Tenkawa>
I'm running ondemand now. i tested perf it was horrid high.. on demand is good
<Tenkawa>
but just switching compilers made the biggest diff
<lanefu>
schedutil is like ondemand, but a little more granular and responsive IMHO
<Tenkawa>
I also restarted because I forgot to start it with ccache doh
<Tenkawa>
I want all the speed increase for subsequent rebuilds I can get
<Tenkawa>
(you dont know me yet but I'll probably build this one build 20-30 times)
<R0b0t1`>
sorry, one more question, is there any way to find all boards that support USB device mode?

interactively or a list somewhere?
<Tenkawa>
if you are looking for a list good luck
<R0b0t1`>
in any way, can use CLI if necessary, was thinking I might have to grep the config files
drobo_00 has joined #armbian
<Tenkawa>
let me see if I can get a cli/programmatic way

must have been the bug in the kernel.. its a little warmer now with gcc but a lot cooler than it was before
<Tenkawa>
er debug
<Tenkawa>
crashed my battery finally lol
<Tenkawa>
time to break out the 10A
