for me it gives "Device 'mmc@1c11000': seq 1 is in use by 'mmc@1c10000'" during the normal load sequence
<anarsoul>
anyway
<anarsoul>
using aliases doesn't look like a proper solution to me
<anarsoul>
why not to fix built-in boot scripts instead?
<wens>
looks like it's a bit fragile, as I just booted again, but this time MMC0 not showing (SD)
<anarsoul>
then would you mind NACK-ing Jagan's series before it lands in u-boot master?
<wens>
anarsoul: I don't know. I think mripard asked that existing user scripts not be broken
<wens>
anarsoul: since it doesn't work for you, you should nack :)
<anarsoul>
*sigh*
<anarsoul>
I already did
<anarsoul>
wens: I think if you update bootloader it's OK to fix your scripts
<anarsoul>
mripard: ^^

wow, my a33 tablet is still on jessie... it's been a few years since I last pulled it out
<DonkeyHotei>
what kernel?
lurchi_ is now known as lurchi__
<wens>
DonkeyHotei: just userspace, I build my own kernels, and since I'm going to test the newest, I didn't bother checking what kernel was there lol
<DonkeyHotei>
i mean, mainline or legacy
<anarsoul>
haha
<anarsoul>
:)
<zilzu>
?
<DonkeyHotei>
because AFAICT neither really worked for most things on a33 tabs
<anarsoul>
I hope Jagan fixes it before it gets merged

<DonkeyHotei>
a lot of the needed drivers in mainline just don't have dt bindings
<wens>
DonkeyHotei: such as?
<DonkeyHotei>
rtl8723bs, for one
<wens>
for bluetooth? WiP. for WiFi you don't even need the bindings
<DonkeyHotei>
i was not able to get the wifi working last i tried
<DonkeyHotei>
nor the touchscreen
<wens>
either you're missing firmware, or power sequencing
<wens>
touchscreen... silead? there's a driver, but you need to retrieve the needed firmware from the original android image on the tablet
<DonkeyHotei>
i did
<wens>
what issues remain?
<DonkeyHotei>
i need to try again with more recent mainline, but among what i never got working were: stk8312, wifi, bt, mali, csi, usb, audio (partially), and i forget what else
<DonkeyHotei>
usb worked only with dr_mode = "host"
<DonkeyHotei>
on audio, left and right channels at the headphone jack were reversed and there was no detection of the plug
<DonkeyHotei>
not sure about the mic
<DonkeyHotei>
neither camera did anything
<DonkeyHotei>
touchscreen errored
selfbg has joined #linux-sunxi
<DonkeyHotei>
nand was not usable
<wens>
the gcXXXX camera sensor modules likely aren't supported
<wens>
csi was only recently added (like the last release recent)
<wens>
mali should be working, provided you can figure out userspace
<wens>
audio... needs a bit of work, but there's nothing one can do about the channels being reversed
dddddd has quit [Ping timeout: 244 seconds]
<DonkeyHotei>
there should be
<DonkeyHotei>
and wrt mali, i never got /dev/mali to appear
<wens>
if the channels are hard-wired in reverse, the codec does not have options to switch them around
<wens>
AFAIK there are tablets that do this :(
<DonkeyHotei>
idk whether they're hard-wired that way, but if so, that's a major oversight in the codec
<wens>
well, there's nothing that can be done in that case. That's just how the hardware is
<DonkeyHotei>
the codec driver is software
<wens>
sure you can tell alsa to switch around the channels in software, but that won't help line-in or other analog inputs being routed around inside the codec
<DonkeyHotei>
there is no line in, only mic
<wens>
so in your case, the software workaround would be fine, and there's already an option to do that within the codec controls
airwind has joined #linux-sunxi
<DonkeyHotei>
i didn't see it
<DonkeyHotei>
but, it's been several months since i looked
<wens>
just set "Headphone Source" to "Mixer", mute "DAC", un-mute "DAC Reversed"
<DonkeyHotei>
any way to put that in dt?
<wens>
no
<wens>
it's all alsa controls
<DonkeyHotei>
ok
<wens>
set it once, and it should remember
<DonkeyHotei>
ISTR there is a gpio to shut the speaker off and on
<DonkeyHotei>
but i could not find how to detect the headphone plug for it
<wens>
gpio to enable/disable speaker would be implemented using the simple-amplifier device / widget. And you would have to fix the routing in the DT
<wens>
hot-plugging is not supported
<DonkeyHotei>
headphones can't be hot-plugged?
<wens>
uh, I mean jack detection isn't implemented
<DonkeyHotei>
i'm assuming that's not just another gpio
<wens>
switching between outputs (if supported) is normally done by pulseaudio in userspace though
<wens>
it's not. it's a feature in the codec
<DonkeyHotei>
are there any examples for the dt routing to the speaker gpio?
<mripard>

wens, mhh so that's only with 800x480?
<paulk-leonov>
wens, with the A33 I have everything supported working "as expected" as far as I know
<paulk-leonov>
but I haven't tried low resolutions
<wens>
paulk-leonov: my Q8 tablets came with 800x480, not 1024x600 screens :)
<wens>
paulk-leonov: so I think I figured out most of the issues
<wens>
paulk-leonov: only one I haven't figured out is AR15/RA15
<wens>
paulk-leonov: semi-planar formats not working on the A23 was because I forgot to enable the frontend lol
<paulk-leonov>
ah :)
<paulk-leonov>
wens, did you try scaling?
<wens>
not yet
<paulk-leonov>
I think there's still something off with the FIR coefficients
<paulk-leonov>
it's broken on the A13
<paulk-leonov>
IIRC AR15 should be backend only
<wens>
I don't know, maybe the image generated by modetest is wrong
<wens>
scaling works for x <= 1
<wens>
with >= 1 the image looks choppy
<wens>
well, same thing on A33
<wens>
paulk-leonov: oh, and scaling doesn't work with the first plane
<paulk-leonov>
wens, mhh interesting, I guess I should give this a try when I get the chance

<pmp-p>
gamelaster: probably, but what would you need someone for exactly ?
<gamelaster>
pmp-p: There is wiki of Sunvell R69, but there is multiple revisions, I have a newer one (this one have real H3, not H2+), and I don't know if I should make a new page with "Sunvell R69 H3 version", or add information into the default one
<pmp-p>
i think that deserves a new page
msimpson has quit [Quit: Leaving]
<pmp-p>
gamelaster: are boards strictly identical ?
<[TheBug]>
gamelaster: the new one is a piece of garbage and should go in a dumpster. I bought one as well and because of the shit quality (as in no QC) ram they use, it can't be used with a standard uboot compilation other than the one for Opi0+2 and then it lacks almost all useful devices in it. It appears that the reason it boots at all is because they use allwinners uboot which is adaptive and tries basically all timings before it gives up and is able to c
<[TheBug]>
There are a few people who got versions with decent ram and they will boot other images
<[TheBug]>
but my understanding is most of those were located in the first batches of the unit
<[TheBug]>
and then they started shipping the crap quality components in their revised versions
<[TheBug]>
gamelaster: not sure what your status is but I spent a good 6-8 hours fighting to make it usable or load Armbian or H3Droid for it with no success.
<[TheBug]>
there may be a way but its gonna take a lot of guess and check
<gamelaster>
pmp-p: The case is same, and it's like newer revision, there is marks it's been made in 2018, so it's relatively new, some parts are similar to images on Sunxi page, but something is totally new
<[TheBug]>
gamelaster: I am staring at it right now
<[TheBug]>
lol
<[TheBug]>
its on my bench of shame
IgorPec has joined #linux-sunxi
<gamelaster>
[TheBug] ouchie, that's not sounds good. You are right, there RAM "layout" is really weird. I wanna try to get Mainline u-boot and kernel working on it, but RAMs will be probably big challenge
<[TheBug]>
I bet y ou 5x the value of the device you won't have much success
<[TheBug]>
unless you got lucky and have good ram
<[TheBug]>
though I did give you the biggest thing to test
<[TheBug]>
get the OPi0+2 uboot
<[TheBug]>
as in the Armbian image will boot
<[TheBug]>
but you will be without USB, ethernet, and about ever other device but hdmi and UART
<gamelaster>
BSP legacy kernel and u-boot, :|
<[TheBug]>
maybe you will have luck with messing with fex for it to enable those items
<[TheBug]>
I wasn't successful
<gamelaster>
well, I have burned SD card with 5.0.0 LibreELEC for H3 (OPi Lite)
<[TheBug]>
does it boot?
<gamelaster>
I'm gonna try it and see what will happen :D
