hi, what is the way to go with cedarx? I want to play hd video on my a20 device but its stuttering. The whole cedarx thing is very unclear, whats the latest thing to do? I don't care about using binary blobs and whatnot

hello. was hoping maybe someone here could point me in a direction to boot emmc on a banana pi m3 while using the sd as storage?
<jrg>
seems like when there is a blank sd in the slot it still tries to boot from it?

install uboot on sd card that will read files/confs from emmc? assuming uboot supports emmc on your soc
<jrg>
yah that was what i was wondering.. if i had to do something like that. it's odd that there is nothing anywhere to configure where it attempts to boot from
<jrg>
i was hoping to use the SD slot for a 64GB mSD as strictly storage and keep the OS on the onboard 8GB emmc
<longsleep>
jrg: it depends where it loads the bootloader from - its totally up to the bootloader when where the OS comes from
Amit_t_ has quit [Ping timeout: 250 seconds]
<ssvb>
jrg: do you already have a bootloader in eMMC?
<ssvb>
the boot priority of different media is sometimes documented in the SoC manual, unfortunately A83t is not one of these
<ssvb>
but you can figure it out by doing some experiments and document the findings here - https://linux-sunxi.org/BROM

Does anybody have an Orange Pi Lite yet? Looks to be very similar to the One, but with wifi, 2 USB hosts and no ethernet

They seem to have put or and a mic back on it too

yes, there are only 2 orange pi models. with options.
<KotCzarny>

Heh. Everything else does seem to be mostly the same with bits missing
ricardocrudo has joined #linux-sunxi

<KotCzarny>
also, grab either opi pc or opi+2e
<KotCzarny>
look for the 'voltage regulator' part not to be the dumb one

I have a couple of opi PCs
<phipli>
You mean the simple voltage reg in the One?
<KotCzarny>
dont remember which models were crippled
<phipli>
I see some stuff saying they might have got their voltages off?
<phipli>
Two voltage mode set with resistors and their both a bit too high
<KotCzarny>
yeah
Shirasaka-Hazumi has joined #linux-sunxi

I wonder if the resistor values are too high or low - could it be fixed by piggybacking?

hmm, the A83t manual says "Support mandatory upgrade process through SDC0 and USB DRD", maybe it is their way to say that SDC0 has a high boot priority?
<ssvb>
the A83t manual has some interesting information about EXP_BOOT_ACK and BOOT_MOD, I wonder what does it mean
IgorPec111114 has quit [Ping timeout: 240 seconds]
<jrg>
apritzel: hm. could be. i'll dd it blank later
<jrg>
and see how that goes.
<jrg>
apritzel: although... it won't even detect the SD when it is inserted WHILE debian is running on the bpi
<jrg>
i was sort of expecting it to be able to at least see the SD when it was inserted. guess that isn't the case for whatever reason
<ssvb>
this seems like a purely software problem, something might be wrong with your bpi kernel or the fex/dts
<jrg>
yah. seems that way. ah well. if push comes to shove and i can't figure it out i'll just use the SD and mount something onto the internal emmc
<ssvb>
as for the boot order, it is handled by the on-chip boot ROM code
<jrg>
is that something that can be flashed or changed?
<jrg>
awkward way of handling heat with it as well. i have a heatsink on it and i guess it still "overheats" so the actual spec speed isn't realistic without a fan

<KotCzarny>
still, will be worth it if it arrives

how much was the opi ?

maybe Xunlong needs to design a board targeting specifically this 22 euro (including shipping cost) price point?

support, but where and how

not sure tbh. i'm looking around trying to see how they did it

but unfortunately my reading time as run out. the dentist about to put me in a chair and pull a wisdom tooth out

anyone know what the minimum SD card size is for Armbian? Specifically the Orange Pi One image - need to test something and only have a 4gb to hand.
<KotCzarny>
4GB should be fine
<KotCzarny>
i think it can even fit in 1GB with some wiggling
<phiplii>
good good
<phiplii>
That's quite awesome
<phiplii>
I have so many 2GB cards from old phones, etc
<phiplii>
that it is nice when you can make a linux datalogger, booting and recording to something so small
<KotCzarny>
keep in mind old(crappy) cards might be the source of many problems
<longsleep>
phiplii: well, those cards will certainly be very slow
<phiplii>
yes :)
<KotCzarny>
they werent designed to be used as a rootfs
<KotCzarny>
also, i had some troubles with compatibility
<KotCzarny>
2 of my 2gb cards refused to boot
<phiplii>
I have more SBCs than SD cards... so sometimes I have to scrape the bottom of the barrel

when I'm too lazy to keep backing them up
<KotCzarny>
root over nfs?

:)
<KotCzarny>
s/root/rootfs/
<phiplii>
For what I'm doing right now, I really should be booting over USB from my laptop...
<phiplii>
but I've not looked at how to do it yet
<KotCzarny>
either via fel mode or simple uboot on sd that will boot via nfs
<KotCzarny>
yeah, but i see 500-900kB/s in the table

after ages using an old TV on linux machines for testing and getting irritated with how the backlight adjusted depending on what was on the screen...
<phiplii>
meaning it got really dark if you only had a login prompt...
<phiplii>
I just looked and realised that the backlight was set to "Auto".
<phiplii>
sometimes it helps to actually look.
<phiplii>
So, back to OPi One voltages
<phiplii>
I've measured the voltage at idle, and it seems to be 1.3v. Then I ran sysbench and measured it again, and I get 1.3v. I'm running Armbian downloaded last week.
<phiplii>
has voltage switching been turn off, have I misunderstood something, or something else altogether?
<KotCzarny>
what do forum says?
<phiplii>
Armbian forum posts from back in Feb say I should expect 1.11V and 1.31V
<phiplii>
but the exact situation, I'm not sure yet
<phiplii>
I'll have a look through the .fex and see if I can see anything obvious
<KotCzarny>
