<apritzel>
KotCzarny: does it mean: supported by upstream code?
<apritzel>
which would then duplicate information from other pages
<KotCzarny>
active mainlining, not just sporadical one-off ports
<MoeIcenowy>
petard_: could you try my other branches?

<MoeIcenowy>
someone in OPi QQ Support Group reported that his opi failed to boot any image after flashing some AliOS(a heavy modified version of Android, used in lot of OTT box in China)-based OTT box firmware his opi refuse to boot any other firmware
<apritzel>
and I don't know if it justifies "good support from community"
<KotCzarny>
though afair my a20 doesnt require any patching?
<MoeIcenowy>
I think it may be burned secure bit
<montjoie>
cannot send v3, stmmac is breaked in next
<montjoie>
so my minor modification cannot be well tested
<KotCzarny>
montjoie: is it broken because of sunxi or upstream?
<montjoie>
upstream
<montjoie>
on H3 TX is now 33Mb/s
<montjoie>
on A20 total break
<KotCzarny>
maybe it broke stmmac for nonsunxi too? which means it should be reported as a regression?
<montjoie>
I wait for the revert
<montjoie>
problem already reported
<apritzel>
MoeIcenowy: that's nasty, but indeed there is some code from Allwinner to burn the fuse, someone could just have copied that

One other thing when I debugged uboot
<petard_>
CONFIG_SPL_MAX_SIZE is set at 0x5fc0

I mean to be able to control the current in the USB ports (to join my Orange Pi Lite), changing to the battery in case of failure in the main supply ...

for Allwinner the SoC from the A series usually come with a PMIC which can have battery support
<masanet>
175/5000

The only available in my country (Spain) is the A10 Lime, but USB ports are limited to 500 mha according to specification, somewhat limited for an Orange Pi Lite.

<BenG83>
Olimex are in the EU
<KotCzarny>
nah, what i meant most allwinners can be ordered from china via ali
<masanet>
BenG83: Comparing with the A10 Lime that is in Amazon, the price including taxes and shipping costs is almost doubled directly at Olimex, that is the reason of "reasonable price". I'm just a stundet.
<masanet>
KotCzarny: I recently bought the Orange Pi Lite from there as I said before, I thought I could use a battery ... I should have known before.
<MoeIcenowy>
Use an allwinner board as another device's UPS is not a good idea...
<KotCzarny>
you can aleay add independent li-ion chArger board
<KotCzarny>
*always
<MoeIcenowy>
If you want a backup power supply, I think you could try to use a Power Bank
<MoeIcenowy>
except if you want some "smart" functions
<MoeIcenowy>
and usually battery-backed devices won't have high VBUS current limit
<MoeIcenowy>
as for these devices VBUS must be converted from the battery voltage (the IPS pin of AXP is directly automatically wired to the currently used power supply, and in the situation with no DCIN or VBUS IN, it will be the battery's voltage, at around 3.5V~4.2V)
<masanet>
I think the Lime2 offers a USB port with 1000 mha. I would like to get an autonomous and self-reliant system being remotely managed, so maybe I need some smart functions.
<MoeIcenowy>
but you can accept only 1A power output?
<KotCzarny>
a20 based board is a good choice imo
<masanet>
KotCzarny: Could you give me more information about charger boards?
<MoeIcenowy>
but you may DIY a "smart power bank" by use some relays after a ordinary power bank
<MoeIcenowy>
(and with your OPi Lite as the controller)
<masanet>
MoeIcenowy: With some adjustments to reduce consumption, I think it would be more than enough for an H3-board. Just Wi-FI and the SoC, nothing about peripherals.
<MoeIcenowy>
it may be the best solution, as these power banks are better on 5v power generating than AXP combined regulators
<MoeIcenowy>
you can connect GPIOs to transistors then connect to relays
<masanet>
I'll look for more information about power banks, maybe it would be the cheapest and more efficient.
<MoeIcenowy>
at least much more efficient than AXP + regulator option.
<MoeIcenowy>
P.S. the Pine64 board even featured a jumper to bypass the 5v regulator when DCIN is available
<masanet>
But at the moment I haven't found in Google any such solution with power banks. I'll continue to search.
<KotCzarny>

I think most power banks (not all) are passive charging or 'pass through charging' capable
<MoeIcenowy>
My power bank cannot be simulaneously charged and drained.
<TheLinuxBug>
well I said not all, but a large amount I was reading about could
<MoeIcenowy>
maybe mine is partly broken ;-)
<BenG83>
I have a EasyACC 10Ah and that can charge and feed through at the same time
<BenG83>
so you get kind of a online UPS
<MoeIcenowy>
P.S. some power banks can even support higher output voltage, although more hacks are needed
<KotCzarny>
hacks == step-up converters? ;)
<MoeIcenowy>
nope

more high-level
