Looking to build a debian stable image for Opi Plus 2E, any pointers?
<dan0_0>
Not a fan of the following things in Armbian:
<dan0_0>
Messes with the bash prompt to show a silly warning on *every* new shell after a kernel upgrade
<dan0_0>
Doesn't have a normal debian installer, leading to issues like incorrect handling of /etc/resolv.conf after copying to NAND, almost certainly others
<vagrantc>
dan0_0: doesn't sound like you want an image, sounds like you want support enabled in debian...
<dan0_0>
MOTD changes and a few other things vs Debian stable keep throwing me off
<dan0_0>
Yea, I mean Armbian is supposed to just be a build system for it, but it seems to be doing much more
<vagrantc>
basically, getting support in debian involves mainline kernel, mainline u-boot, and getting the board recognized in flash-kernel
<vagrantc>
and then getting all the appropriate modules enabled in the debian kernel...
<dan0_0>
Yeah, its a pretty extensive project that has only been undertaken for A10/A20 it looks like
<vagrantc>
depends on what you need, i've got a few orangepiplus2 boards running just debain, but they're headless and use a usb ethernet adapter
<dan0_0>
I'm fine with running a custom kernel/uboot, but I just am not a fan of the changes Armbian has made around the edges

dan0_0, you might want to mention your concerns over in #armbian or on their forums. Getting Armbian support is accidental.
<dan0_0>
Eh, #armbian has 16 users in it, and tkaiser and a few others who work on Armbian are here in #linux-sunxi, but never in that channel

swiftgeek: for the silead chips, the blob is actually calibration data
<swiftgeek>
yes i know that
<swiftgeek>
i just want to fix stuff for my board which is pretty close to reference one
<swiftgeek>
wens: do you have software for creating it by any chance ;)
<wens>
swiftgeek: nope
<wens>
i reached out to silead engineers back when hansg started work on the silead driver
<swiftgeek>
i have to ask somebody to transcribe the title of it
<wens>
they actually have to have their engineers go on site with special equipment to do the calibration
<swiftgeek>
it's not called ctouch suite at all
<swiftgeek>
nah
<swiftgeek>
but dongle is quite a special one
<wens>
so the possibility of someone doing it themselves is pretty low
<swiftgeek>
just because of the scarcity of the dongle
<wens>
well, that and you have to know what you're doing
<swiftgeek>
well
<swiftgeek>
i don't know chinese but it's not THAT hard from looks of it
<swiftgeek>
oh my i'm retarded, forgot to save whole guide
<wens>
i guess the point is the requirements make reversing the blob specs kind of low priority if not useless
<swiftgeek>
wens: but it takes header files as input to create calibration file

I noticed that the USB OTG is still wip for h3 according to http://linux-sunxi.org/Linux_mainlining_effort#Status_Matrix -- would it be possible to mainline that soon since it seems to be a fairly small patch and armbian and others have supported it for a long time now?

MoeIcenowy: but when it is ok to say that there is some support? I guess if it boots mainline kernel appropriately, it's already a first step :)
<MoeIcenowy>
we may speak "mainline support"
<MoeIcenowy>
but I think "sunxi support" means the sunxi-3.4 branch
<miasma>
i see
<miasma>
that might be confusing for some readers not interested in < 4.x kernels
<miasma>
the 'yet' part kind of implies that some developers would possibly like to have the support in the 3.x branch some day

hmm could h64 be mentioned as a variant on a64 page just like h2+ is listed on the h3 soc page?
<miasma>
the a64 page already listed a h64 htpc as a a64 device
<KotCzarny>
miasma: see a33/r16 and similar pages
<KotCzarny>
though in this case its just a rename
<miasma>
the h64 page mentions some differences
<KotCzarny>
yes, the ones i've managed to find
<miasma>
well I thought a short intro with link to [[h64]] could be mentioned on the a64 page under variants
<miasma>
and if there's more differences, those on the h64 page
<MoeIcenowy>
I think H64 page should be merged into A64
<miasma>
k
<KotCzarny>
but h64 is so niche chip , do you know any devices using it?
<miasma>
the wiki only lists one or two
<KotCzarny>
one.

sun50iw1p1 series just have fewer devices than other ;-)

hopefully.

nah. I'm just being realistic. I'm one guy working a full time job doing this as a sort of hobby.

you have the problem of the binary only kernel module, you need to find out how the hardware is initialized

Any of the SoPine owners looked into mainline DRAM support already (LPDDR3 and not DDR3/DDR3L)? I could only find legacy boot0 in one of longsleep's repos but nothing 'blob free'...
<apritzel>
tkaiser: LPDDR init in U-Boot> I started looking at it
<apritzel>
I actually found some DDR code in the NanoPi-A64 BSP
<tkaiser>
dan0_0: To keep this channel clean it would be great if you could open a new thread in Armbian forum (dev section) and explain what annoys you (interesting for me). Maybe most if not all issues can be resolved by making use of image customization script that get called in the end (I use this heavily to tweak OS images we use at customers)
<dan0_0>
Yeah, I did, lemme go link to that
<tkaiser>
apritzel: Good to hear. Can some of the code used for BPi M3 (sun8i but also 2GB LPDDR3) maybe reused here?
<apritzel>
tkaiser: sure, this is one driver in U-Boot anyway
<apritzel>
tkaiser: if you mean "H3" with sun8i

I printed a case for my PC2 and now it runs a reasonable amount slower. Temps are slightly lower, but may not quite be at equilibrium. So, the thermal budget/throttling seems to be working great.
<willmore>
Board still stock--no heatsink and no enhanced airflow.
<willmore>
Okay, now that it's cooked a bit longer I'm seeing odd behavior. The temperature and clock speeds are fluctuating quite a bit. Clocks peak at 1008MHz and dip down to 720. Temps go from 62C to 75C.
<willmore>
Is there some kind of PID loop that controls this or a state machine of some sort?
<TheLinuxBug>
I have it in its 'Orange Pi' branded acrylic case and noticed its a bit slower, but I have also added a heatsink since which did improve a good amount.
<TheLinuxBug>
wnever checked temps but may be worth seeing what it runs at
