15:10 < KotCzarny> multi_io: you have 2 options. 1/ mainline one, which doesnt use b53 module, 2/ patching b53 back into mainline
<multi_io>
I read the thread you mentioned, but it's still not clear to me what works on mainline
<multi_io>
https://github.com/igorpecovnik/lib/issues/511#issuecomment-258106972 seems to explain just how to set up a software bridge and VLANs on existing physical interfaces lan0..3 and wan, which I don't seem to have after booting on mainline kernel without the b53 driver loaded
<multi_io>
so how do I do this without b53?

multi_io: i think it's in CONFIG_HAVE_NET_DSA
<KotCzarny>
it was long time since i've built the kernel
<KotCzarny>
you can check what armbian sets in config
<multi_io>
no dmesg output on rmmod / modprobe of the b53_* things
<KotCzarny>
what dtb are you using?
<KotCzarny>
hmm, [ 4.230737] sun7i-dwmac 1c50000.ethernet (unnamed net_device) (uninitialized): PHY ID 03625f24 at 0 IRQ POLL (stmmac-0:00) active
<KotCzarny>
unnamed net_device? wth?
<KotCzarny>
if you do ifconfig -a or ip addr what interfaces show up?
<multi_io>
only eth0, wlan0, bond0
<KotCzarny>
maybe stmmac broke b53
<multi_io>
(before the script ran -- after than I also had eth0.10[12], but anyway)
<KotCzarny>
funsies
<KotCzarny>
can you try 4.9.x ?
<multi_io>
how do I know which dtb I have? sorry
<KotCzarny>
your uboot config should load some dtb file
<KotCzarny>
so probably in /boot/boot.scr
<KotCzarny>
i would suggest you checking latest 4.8 or 4.9 then if those work most likely stmmac broke
<multi_io>
ok I can try that.
<multi_io>
how do these dtb things work? armbian provides them for all the supported boards, and u-boot just loads them so the kernel knows what hardware is there?
<KotCzarny>
those dtb files are compiled with the kerne
<KotCzarny>
when you do make dtbs
<KotCzarny>
then you copy the one you want to /boot and make it load with the kernel
<KotCzarny>
they are describing your hardware, what devices you have, where to find them etc, so kernel know what to initialize/run
<KotCzarny>
*knows
reinforce has joined #linux-sunxi
<KotCzarny>
they are in arch/arm/boot/dts/
<KotCzarny>
and you only need to compile them once (they dont depend on kernel .config)
<KotCzarny>
you can also just use armbian's provided kernel for bpir1
<KotCzarny>
could save you some hassle

techping: the designware uart is compatible with 16650, with a minor glitch in handling baud rate changes when the uart is busy
<wens>
since this never happens in u-boot, one can ignore it, and just use it as a standard 16650

later versions actually fix it, with a register switch to change the behavior

that switch is available in the allwinner version

The behavior of the WiFi is super strange, if I keep pinging I don't have a problem but if I stop for a short amount of time it gets a ping every 20-30 attempts and sometimes it recovers.

TheLinuxBug: Saturating GbE of course, won't be different with ARMADA 3700
<tkaiser>
TheLinuxBug: Just as a general advice when playing with iperf/iperf3. You need 3 devices for tests. Two to ensure you exceed 940Mbits/sec in between so you can test against the real (3rd) device. Otherwise results are numbers without meaning.
<TheLinuxBug>
tkaiser: what do you consider saturated, as I was saying yesterday I was getting ~75M/sec up and ~70M/sec down, though this could be a limitation of the server I was testing to and not the ESPRESSObin.
<tkaiser>
And then both tools are bottlenecked by CPU performance so when you downclock your SoC to the min you get worse numbers. Also behaviour might depend on GCC version the binaries have been compiled with. Which OS do you use currently?
<TheLinuxBug>
Debian on the server I am testing to and Ubuntu 16.04 on ESPRESSObin
leviathan has quit [Ping timeout: 260 seconds]
<MoeIcenowy>
no I think the number will be a low bound, saying that the speed will be at least not worse than the number you get ;-)
<tkaiser>
TheLinuxBug: 'Saturated' is 940Mbits/sec. Regarding Debian vs. Ubuntu please see different results here: https://forum.armbian.com/index.php?/topic/1917-armbian-running-on-pine64-and-other-a64h5-devices/&do=findComment&comment=14673

are you saying there is a driver issues that prevents the NAND from working as well?

Of course I see it can be 'slodered' to it after installing the pins, but I was hoping to avoid even having to mess with adding the pins

MoeIcenowy: yes but now I am very confused, does the board come with SPI and NAND or is it simply compatible with them. Cause I am telling you, before I backed it I read the specs and there was listed in it a 128MB NADA and the SPI as coming on the board. Even someone in comments asks about this but doesn't get a very clear answer.
<MoeIcenowy>
only compatible with it.
<TheLinuxBug>
thats very frustrating
<TheLinuxBug>
so basically when I receieve the board I will have no way to use the Wifi at all unless I solder the pins on... pft
<MoeIcenowy>
and for SPI NAND it may be only able to work as storage, but not boot from it.
<TheLinuxBug>
Well I figured , based on what I read and watching the video, that uboot was in SPI and it would load system from NAND
lurchi__ is now known as lurchi_
<MoeIcenowy>
no the U-Boot is on SPI NOR.
<TheLinuxBug>
but I guess at this point your saying SPI isn't even included and obviously since they changed their page to no longer show the specs I am gonna guess they are no longer providing the NAND either.
<MoeIcenowy>
I think they never provide SPI NAND at all
<MoeIcenowy>
and SPI NOR is always optional, since it's on indiegogo
<TheLinuxBug>
im telling you I was very careful reading before I backed it and it was there on the page..
<TheLinuxBug>
someone in comments even says
<TheLinuxBug>
"Hi, great project, I just have one question: In the diagram I see “SPI Flash Nor 16MB/32MB Nand 128MB”, but in the “Zero’s system & application example” under buildroot you say " you can put the kernel&rootfs into 8MB SPI flash". So what will be the size of SPI flash on the final boards?"

mripard: ccu-sun8i-a33 driver seems to have some bug
<MoeIcenowy>
when booting, the clock value is 0x90001b21, which is 1008MHz based on my calculation
<MoeIcenowy>
but ccu-sun8i-a33 reports it as 2016MHz

mripard: it seems to be a grammar error in ccu_nkmp_recalc_rate()
<MoeIcenowy>
the priority of >> is lower than * and /
<MoeIcenowy>
you used parent_rate * n * k >> p / m
<MoeIcenowy>
which is equal to (parent_rate * n *k) >> (p / m)
<MoeIcenowy>
but we want parent_rate * n *k / m >> p

KotCzarny: I was using the wrong $BOARD yesterday (bananapi instead of lamobo-r1)
<multi_io>
:-O
<KotCzarny>
happens to the best :P
<multi_io>
with the correct one, it all works
<multi_io>
yeah, thanks for your help
<KotCzarny>
all the mentioned warnings about b53 still hold true for mainline
<KotCzarny>
ie. in poweron/after reset state is acting as a dumb switch
<multi_io>
I bought a USB-Ethernet adapter today, I guess I'll use that for the WAN connection
<multi_io>
so the whole VLAN isolation thing won't be necessary

mripard: I sent out the patch, please check it
<KotCzarny>
tbh, i use bpir1 at home and so far isolation works, i've added li-ion battery though to minimize risk of resets
<KotCzarny>
plain 18650 cell is enough
<KotCzarny>
as charging circuit is already on board

I just connected two machines to the lamobo-r1 on two of its ethernet ports, set up static IPs on them, booted the board, and the two machines could NOT ping each other until you run ip link up lanx/wan on the board.

hm, no, immediately after reboot they can ping each other for a few seconds until the kernel on the board gets to disable the interfaces (apparently)
