can you try my updated sunxi-wip-a64 branch...I'm away from my hardware now

tomorrow, it's already 11pm here

ok....I'll try my branch with your config later...if it doesn't work I'll revert to a rc label
06:09

FWIW, clock dividors setup is wrong in mainline
06:09
<
anarsoul >
and BSP seems to use WSS = 3
06:11
<
codekipper >
before you head to the land of zzzs could you send me logs from mainline for silent and playing
06:11

I hardcoded values from BSP for CLK_DIV and FMT0 regs and I'm getting some sound in R channel
06:12
<
codekipper >
thanks
06:13
<
anarsoul >
oh, actually there's some sound in L channel as well, but it's very quiet

alright, if i manage to get chip-mali-userspace in chip-buildroot, i can try to compile qt with opengl es support, and the demos will use libMali, do you guys think this sounds right?

marble_visions: I've ported a package for r6p2 libMali,
16:30
<
benettig >
but when I start malitest or Qt5, it gives me BAD_ALLOC
16:31

benettig >
tried on a20-olinuxino-lime and also a33-olinuxino
16:31
<
jernej >
benettig: Error 0x3003 can happen when you have different versions of userspace and kernelspace driver
16:32
<
benettig >
jernej: I have both r6p2 on kernel driver mali.ko and libMali.so
16:32
<
benettig >
I've used the ones provided by mripard
16:32
<
benettig >
mali.ko with high verbosity load correctly with cma
16:32
<
jernej >
well, that was my experience
16:33
<
jernej >
as soon as I matched them, the error was gone
16:33
<
benettig >
jernej: did you manage to have r6p2 working?
16:33
<
jernej >
yes, no big deal
16:33
<
jernej >
but I used gbm version
16:34
<
benettig >
so you use libdrm?
16:34
<
benettig >
maybe I should compile with libdrm on
16:34
<
benettig >
and Qt5 using eglfs_ksm ?
16:35
<
jernej >
I'm not familiar with that
16:35
<
benettig >
but did you use malitest as is or did you modified it?
16:35
<
jernej >
but blobs provided by free electrons doesn't have gbm/wayland version
16:35
<
benettig >
oh, but where can I find other blobs?
16:38
<
benettig >
would it work for A20 and A33?
16:39
<
jernej >
you have to have libwayland-server.so and libwayland-client.so even if you don't use wayland
16:39
<
jernej >
yes, why not
16:39
<
benettig >
and ever tried the fbdev version?
16:39
<
jernej >
it depends on GPU not SoC
16:39
<
benettig >
that's right
16:40
jemk has joined #linux-sunxi

fortunately fbdev days are behind me

not with mainline, only with bsp kernel
16:41
<
benettig >
ah, so you suggest to move to wayland, right?
16:41
<
jernej >
oh, for the record, I did everything that with H3, but I don't see the reason why it wouldn't work with A20 or A33
16:41
<
jernej >
wayland or gbm, if you run mainline kernel
16:41
<
jernej >
with bsp kernel, you can't
16:41

oh, thank you very much!

take a look here for a build script for both, kernel and user space driver

it is libreelec build system, but you'll manage

it should allow to turn off and on the power to external usb devices, if the PMU/USB-controller, does not support this

i guess you can get good usb hub for the price of two with full port control
17:29
<
KotCzarny >
cool thingie though
17:31
<
da3m0n22 >
sure, but then i'd need additional power socket and usb hub with power control (digital), which is hard to tell from product specs
17:37
<
da3m0n22 >
and i need like 600 pcs to deploy in the field
17:38
<
miasma >
what a piece of junk. wasting the whole usb port for that
17:38
<
pmpp >
well it has a darlington and probably can use libusb userspace
17:38
<
da3m0n22 >
miasma: know better solution, if the boards PMU / USB controller does not support fully cutting usb-vcc to the device?
17:39

miasma >
just criticizing the usb interface
17:40
<
pmpp >
maybe you have /dev/gpiomem ?
17:40

da3m0n22 >
miasma: oh you mean on that pmpp's link ?
17:42

some kind of esp8266 + mosfet + dc-dc converter hat would be nice for many boards
17:43
<
miasma >
it would convert 12..24V -> 5V and feed the GPIO pins via the mosfet
17:43
<
miasma >
esp8266 could control power on/off
17:44
<
pmpp >
relay would last longer
17:44
<
pmpp >
it is powered only the time required to reset device
17:45
<
miasma >
relays may burn your device with voltage spikes
17:45
<
pmpp >
there's no inductive load involved there
17:45
<
KotCzarny >
isnt powercutting prone to voltage spikes too?
17:46
<
pmpp >
but i like esp too :)
17:46
<
pmpp >
KotCzarny: if there's an inductance yeah
17:46
<
miasma >
i'm pretty sure it doesn't require any inductive load to cause those spikes, but i don't have a degree on electric engineering

also is it u-boot or fex that sets that USB is powered even when the SoC is turned off ?

that's a very low level question that requires precise board info i guess
17:50

source code type question
17:50

i would assume both

bpi-m1 and i can issue schematics, usb-vcc is running through axp209, not directly from input

da3m0n22 >
the name is "BPI-M1 schematic.pdf"
17:53

pmpp >
da3m0n22: sorry i am another kind of low level i would get a relay and some usb2dupont cables

and python :P

codekipper: so simple-audio-card,mclk-fs should be 128

also we need to take into account that wss = 3 on A64 internal i2s in bclk_div calculation
