don't know for the exact this implementation, but 3d functions are considered experimental
<RzR>
recent mali have better lima support
<ArmbianTwitter>
@Hacksterio (Hackster.io): "The Helios64 is an impressive second launch from Kobol, and one which is leaps and bounds ahead of its predecessor — but the company still has some way to go with the project." https://t.co/WNlpZk6R4c (20s ago)

Any mali users around ?

it's a good candiate
<IgorPec>
... chech other boards with this chip, they are usually better quality
<IgorPec>
there are at least three revisions of this boards around in the wild

the rockpro has a better gpu better support
<archetech>
3x price it better
<archetech>
Twister OS - Armbian for rockpro and 4c looks nice
<pakcjo>
wait, i'm confused, it seems that 4GB are for the NPU
<IgorPec>
what you will do with it?
<IgorPec>
you need software
<pakcjo>
Yes, not sure, I thought that the 8GB were all available, but it doesn't seem to be the case... 4GB for the system and the other 4 for the NPU.
<pakcjo>
I don't have any use for npu
<pakcjo>
but would love to have an arm board with 8GB
peterm6881 has quit [Remote host closed the connection]
<IgorPec>
with software support or without?
<pakcjo>
with software support of course
<IgorPec>
all current rockchips and amlogics and allwinners can only have 4g
<chewitt>
pakcjo RPi4?
<pakcjo>
is it a hardware/design limit or commercial?
<Xogium>
I believe hardware
<chewitt>
RPi4:~ # free -m
<chewitt>
total used free shared buff/cache available
<chewitt>
Mem: 7722 270 7092 81 359 7149
<Xogium>
yeah but noone likes rpi around here, and with good reasons
<IgorPec>
total used free shared buff/cache available
<IgorPec>
and we also came to rev C and still not sure we are there
<stipa>
it can always be better
<Xogium>
you guys know what's most open platform ?
<Xogium>
I went with stm32mp… I think it's one of the most open I ever saw
<pakcjo>
how does the development process to support a board goes? do you get the datasheets from the manufacturer? some dtb? or is it all reverse engineering or so?
<IgorPec>
a combination
<IgorPec>
but
<IgorPec>
datasheets can very in quality a lot
<pakcjo>
I bet
<IgorPec>
so you can easily waste a lot of time relying on them, while reality is different
<Xogium>
*cough cough* allwinner
<stipa>
and lose bucnh of nerves
<Tonymac32>
right, they make a decent starting point, but there are always errata, often uncorrected
<IgorPec>
dtb comes from chip vendor and its tweaked by boark makers ... which can be total amaters
* Xogium
hides
<Tonymac32>
Xogium Rockchip
<IgorPec>
some parts are closed
<Xogium>
that was ironic ;)
<Tonymac32>
:P
<Xogium>
or are you implying that rockchip is even worse off than aw ?
<Tonymac32>
they have some very... interesting pipeline from the video system to everything else
<Tonymac32>
and it never seems to work right
<Xogium>
charming…
<Tonymac32>
even their kernel, the camera and DSI stuff is just horrendous
<Tonymac32>
anyway, enough griping
<Xogium>
I mean, for my project, I went with the stm32mp, because, somehow, it felt right to pay a bit more for a good supported platform on mainline, and actual tons of complete, correct documentation, and outright support direct from st
<Tonymac32>
right
<Tonymac32>
the microchip ones aren't bad either if you need a deeply embedded SoC
<Tonymac32>
I'm just starting to learn the NXP stuff, they keep a lot of crypto stuff so locked up you'll never see it though
<Xogium>
yep that's what I heard
<Xogium>
though…
<Tonymac32>
in all caes I like having a real-time Cortex-M laying around
<Tonymac32>
(I make equipment sometimes)
<Xogium>
oh, yeah. I've never played with those, yet
<Xogium>
but, it sounds like it could perform some action even when linux is asleep
<Tonymac32>
yes, they are independant other than some shared memory space
<Tonymac32>
and latenvy isn't a problem unless you right shitty microcontroller code
<Tonymac32>
latency*
<Xogium>
so could you technically use the m4 to reflash the main linux OS or run some kind of recovery mode ?
<Tonymac32>
hmmmm, that I haven't looked at, it might not have that kind of hardware access
<Tonymac32>
it might be able to trigger the main bootloader
<Xogium>
I was thinking the m4 could handle the aptic touch
<Xogium>
I think it's the name, at least
<Xogium>
vibration when you start charging, etc.
<Xogium>
I was also thinking of sending some kind of message via vibrations
<Xogium>
like you know how boards like the rpi blink their leds in a pattern to indicate boot problems
<Xogium>
blind peeps can't notice that, so I thought of making it vibrate in a pattern if anything goes real bad
<stipa>
you would like to monitor the board with the m4 chip
<Xogium>
yeah, that
<Tonymac32>
That might be doable, but it depends on which peripherals you can hand over to it
<Tonymac32>
I think it's generally intended to do external control, but...
<Xogium>
yeah that makes sense
<Xogium>
maybe this should be handled with a non integrated controller instead
<Tonymac32>
for things like haptic feedback, that is external control to a large extent. charge status from an external controller/etc
<Xogium>
yeah…
<Xogium>
hmm
<Xogium>
it's my first time ever working on such a project but man I love it :D
<Tonymac32>
it's fun digging into new things
<Xogium>
that all started because of me, but we're 3 onboard now :p
<Xogium>
trying to make a good audio player/recorder/note taker for the blind, at a reasonable price
<Xogium>
and with good performance and no crappy hw
<Tonymac32>
IgorPec have we cleaned up the fusb302 on rockchip 64 yet?
<Tonymac32>
Xogium high bar :D
<Xogium>
oh yes
<Xogium>
ain't gonna be easy, but what matters is enjoying the work
<IgorPec>
Tonymac32: not sure
<Tonymac32>
After seeing a VGA output retro computer emulator running on an ESP32 I have to say that might be an option given the brute force power of the thing
<Xogium>
though… some stuff do that already, but it sells for $400 or so, and it's crappy hw along with crappy software able to read only a few file formats… No ogg, no flac, no opus, etc.
<Tonymac32>
it also has I2S input so you can use nice microphone
<Xogium>
and the update mechanism is badly designed aka no rollback, and no way to unbrick it yourself
<Tonymac32>
oooof
<Tonymac32>
yeah I can see linux being the go-to if you can get the BOM cost down to a reasonable level
<Tonymac32>
IgorPec I'll take a look. In theory the mainline driver is fixed
jl4_ has joined #armbian
<Xogium>
we found a neat platform with that stm32mp, and an awesome SoM made by seeedstudio
* jl4_
Mbian newbie here ...
<Xogium>
the SoM integrates the SoC, ram, eMMC, and pmu
<Xogium>
and best of all, no soldering required, just stuff it on a carrier board with its 70-pins connector
<jl4_>
I just flashed my Orange Pi 3 microSD, inserted it on the given slot and booted... Apparently is up and running. Yet,i'm not able to find it on my LAN... what am i missing ?
<IgorPec>
"what am i missing" -> searching forums
<jl4_>
(LAN LED is flashing and Pi LED it stays on (red color))
<IgorPec>
did you search forums?
<Xogium>
no soldering is a major selling point for us, given that 2 of the project members are blind, and it will make it super easy for people that want to replace a dead internal storage… Remove the SoM, put the new one up, and flash with usb DFU
<jl4_>
i don't understand .. forums ?
<IgorPec>
forum.armbian.com
<jl4_>
ah, thanks ... i'll give a look at.
<IgorPec>
its a bug
<IgorPec>
and we have no solution
<Xogium>
SoM itself's $26. Could have been a lot worse ;)
<jl4_>
Um, this on latest (Orange Pi3) Kernel 5.9.5 ... May use an older armbian version ?
<IgorPec>
you can
<jl4_>
(typo : may i use..)
<IgorPec>
just don't udpate
<jl4_>
sure... i'm about to flash Armbian_20.11_Orangepi3_buster_current_5.8.16
<jl4_>
BTW... i tried with an OPi4 i have here too... same connectivity issue. May the both OPi3 and OPi4 issues correlated ?
<IgorPec>
no, opi4 is very different beast and should work fine
<IgorPec>
just bring enough power
<IgorPec>
its hungry
<jl4_>
umh...ah, here might be the issue, as long as i'm missing OPi4 's power supply
<jl4_>
i'm re-using the OPi3 one with OPi4. ...could this be a problem on power shortage ?
<lanefu>
yeah actually I used a official OPI USB-A to DC-barrel plug cable that i've had forever on my opi4 and it wasnt enough.. had to use a different cable
<lanefu>
btrfs in theory is SSD optimized.... and i _really_ prefer it for docker
<lanefu>
because docker's storage driver can use it natively via snapshots and suvolvumes n shit
<lanefu>
so no overlayfs2 or aufs or anything
<lanefu>
btrfs's snapshot features are cool too
<lanefu>
and you can have compression etc
<lanefu>
anyway. it had a stigma a while back, but i prefer it for general use
* Tonymac32
mutters in latin while holding up crucifix
<Tonymac32>
:D
<lanefu>
Tonymac32:thats fine you can like hte ext4 journal trash your sdcard
<jl4_>
I use Btrfs on my laptop a lot ... in so useful combination with openSUSE's snapper
<Tonymac32>
lanefu lol
<jl4_>
...to smoothly rolling'back when things go wrong/broken. So useful.
<jl4_>
you rollback to a previous/older (system) read-only image...when checked that is working (again) as expected, reboot from that one. All automagically pre-configured for you, BTW.
<lanefu>
yeah pretty cool.. I was annoyed at first because i saw 32bit memory controllers, but CNX software guy said there's 2 memoy controllers to 8GB ram possible

Hey Tonymac32 .. I've got a bunch of little protoboards like this.. https://armbian.lane-fu.com/linx/s/k849u78j.png what's like the intended purpose fo rthe extra big pads on either side
<Tonymac32>
you can do ridiculous things like surface mount headers on like edge connectors
<Tonymac32>
and switches
<jl4_>
On Bash... how can i get to know wether if my orangi Pi runs armhf or arm64 ?
<jl4_>
ah.. donde, ' uname -a'
<lanefu>
Ohhhh
<IgorPec>
jl4: your orange always runs correct arch :)
<Tonymac32>
hehe we don't exist solely because of a fragile and outdated ARM11 ecosystem
