hanetzer : is uboot changes required for 18.04 or does it make everything better in general?

x86 low power has nearly reached parity with the arm so I'm nearing he point of giving up on ARM and going back to x86
01:19

akaizen: as it currently stand, 32bit rockchip SoC with 4gb of physical ram are not supported in mainline u-boot atm
01:19
<

most 3288 sbcs / not chromebooks have 2gb or am i mistaken
01:20

woww, what do you need all that ram in a router for?
01:20

akaizen: my two asus c201 chromebooks have 4gb :)

nvm confusing two channels
01:22

don't the chromebooks have coreboot support now, isnt that preferred since theres no rk binaries

01:27

hanetzer : ^
01:32
<

akaizen: honestly, coreboot+depthcharge is to finicky for me. the u-boot I use is without rk binaries as well.
01:32
<
akaizen >
hanetzer : can all rk3288 platforms boot via uboot w/o rk bins now?
01:33
<
hanetzer >
akaizen: no idea. there's a bit of work to be done to get sdcard/usb boot to work when booting from spi flash
01:33
<
akaizen >
hanetzer so sdcard boot needs work, what about emmc?
01:34
<
hanetzer >
emmc works.
01:34
<
hanetzer >
has to do with regulators and such needing to be flipped and jtag disabling (muxed with sdcard)
01:36

right now my only remaining boards are one firefly-rk3288 and ugoos ut3+ for HDMI in on linux

if I can get them on uboot + ubuntu 16.04/18.04 they'll server as nice little servers for a long time

heh. sure
02:00

it's broken real bad.
02:01

that said, i haven't tried it on another board ... i've got three ... maybe there's something weird about the emmc on that one
02:01
<
akaizen >
if i've learned anything with these arm boards these past few years, is pretty much trust nothing
02:01
<
akaizen >
do quick sanity checks as soon as possible to determine a baseline
02:02

im completely jaded ok rockchip arm
02:03

u-boot is released only on odd-numbered months

im curious what everyone thoughts are on rk3399, i expect more of the same as rk3288 release
02:04
<
akaizen >
vagrantc: thanks i'll give that a spin on my firefly and ugoos and 16.04/18.04
02:04

two firefly-rk3399 with mixed reults ... the puma-rk3399 is really nice

is the puma the RBD?

some industrial engineer folks give me some hope of a well designed board
02:07
<
vagrantc >
that said, i've found the firefly-rk3399 boards really finicky ... they might be fine if you never wanted to or needed to upgrade u-boot ...
02:07
<
akaizen >
haha hopefully they aren't cherry picked samples
02:08
<
akaizen >
i gave up on firefly
02:08
<
vagrantc >
the firefly boards in general are really hard to recover if you write to the eMMC a bootloader than kind of works but doesn't really work
02:08
<
vagrantc >
since it boots from eMMC before microSD
02:08
<
akaizen >
visited their factory was going to order a large qty and then they could never deliver / fix issues
02:08
<
akaizen >
the original firefly was fairly easy to get into ROM mode
02:09
<
akaizen >
mine is from 2014/2015?
02:09
<
vagrantc >
akaizen: depends on if your bootloader fails completely, or works just enough that the boot rom thinks it's job is over
02:09
<
akaizen >
i falshed it so many times i've had both
02:10
<
akaizen >
i think in 2015 we tested over 2000 builds
02:11
<
akaizen >
anyway most of the problems will be a thing of the past soon
02:11
<
vagrantc >
what i love about the puma-rk3399 board is that it has a usb interface to power cycle the board and switch between boot media
02:11
<
akaizen >
oo, OOB control thats nice
02:11
<
akaizen >
very dev/automation friendly
02:11
<
akaizen >
we eneded up building our own system for that based on LAVA
02:11
<
vagrantc >
and physical switches to set boot order (when you're not using the usb control)
02:12
<
akaizen >
thats nice too, having to short pins via paper clip is finicky :x
02:12
<
akaizen >
i am curious about i.mx8 tho
02:12
<
akaizen >
wandboard seems very compettive
02:12
<
akaizen >
and latest AMD embedded offerings
02:12
<
vagrantc >
i'd even settle for a jumper ... but shorting pins ... no fun
02:13
<
akaizen >
on my rk3288 tv stick
02:13
<
akaizen >
it was fking shorting traces
02:13
<
vagrantc >
there's an imx8 wandboard variant?
02:14
<
vagrantc >
i've been quite happy with the wandboards for the most part
02:14
<
akaizen >
their parent company is TechNexion
02:14
<
vagrantc >
still only 2GB of ram :/
02:15
<
akaizen >
i think the deluxe version is supposed to be 4gb
02:15
<
akaizen >
that could be a typo or not, its been a couple months since i spoke to them
02:16
<
akaizen >
this should be obvious but only after epxerience have i realized the solid boards are made by the embedded / industiral computer folks. all these kids moonlight as hw designers while i love the enthusiam its suicide to build a business / products based on their designs
02:19
<
akaizen >
haha my firefly still has gentoo on it
02:24
<
akaizen >
do i scrap this and just get a cheapo amd platform.. will probably save a lot of headache

ooohhh interesting
02:37
<
akaizen >
what do you use PPC for?
02:38
<
akaizen >
x_x base system is 4K
02:39
<

think i can get 2 epyc systems for that much 1 epyc system + 7 gpus
02:39
<
hanetzer >
akaizen: I don't use ppc, other than a few routers. I'm just interested in powerful hardware with a fully foss stack :)
02:39
<
akaizen >
yea i saw that, open BMC and everything + pci-e 4.0
02:40
<
akaizen >
hanetzer : got any recommendations for low power router that can do 500 Mbps/1 Gbps with QoS ?
02:40
<
akaizen >
i was thinking of turning one of these arm board into a ubuntu router
02:40
<
akaizen >
sips 5W and gives me ~950+ Mbps
02:40
<
akaizen >
but qos might kill tha
02:41
<
hanetzer >
akaizen: not really. I have 30 cisco meraki mr24s to deploy here soon :)
02:41
<
hanetzer >
those are powerpc iirc
02:42
<
akaizen >
how do those compare to the ubiquiti stuff?
02:43
<
akaizen >
ha the meraki office are in my old offices
02:43
<
hanetzer >
no idea, but once you flash lede/openwrt on them they are pretty good. I managed to find lots of 10 for $100usd on ebay :)
02:43
<
akaizen >
cant beat that
02:44
<
hanetzer >
they're older now, but hey, old enterprise is nice stuff :)
02:44
<
akaizen >
can you spare any
02:44
<

i would replace my home routers with those
02:44

all embedded folks tinker alot ;p
02:47

its a job requirement
02:48

then again i'd say any kind of good engineer tinkers alot
02:48
<
hanetzer >
and I use the gentoos :P
02:48

i couldnt handle compiling world on an arm

x86 and arm, thought the arm is not in active use because need time :P
02:52

i had arm-chair theorized a cross compile system
02:52

anything that needs to compile on arm send it over to the x86 and pull back the bins
02:54

hanetzer : oo found a 5 pack for $100 :) know of any 802.11ac gear on hte cheap?
02:54

not off hand.
02:55
<
akaizen >
i picked up a ac68 for $50 ish running merlin right now
02:55
<
akaizen >
perhaps i should try lede
02:56
<
hanetzer >
well, lede and openwrt remerged :)
02:56
<
akaizen >
yea so i heard but the site and forums are still kinda a mess
02:56
<
akaizen >
and openwrt lost a bunch of posts
03:00
<
hanetzer >
sucks, but I dont' use the forum anyways so eh :)
03:01
<
akaizen >
was researching some port multiplier stuff in openwrt and marvell was taking to long to respond, shame those posts look lost
03:01
<
akaizen >
i find the lede / openwrt luci ui very confusing so im trying minimal ubuntu with the packages
03:02
<
akaizen >
i guess i could try lede without luci but that seems to gimped
03:02
<
akaizen >
waaaaait a min, does lede support rk3288
03:05
<
akaizen >
openWRT for firefly: openwrt-15.05+kernel4.5
03:05
<
hanetzer >
not yet, but no reason it can't :)
03:05
<
akaizen >
meh so many issues
03:08
<
akaizen >
so whats the boot process for rk3288 with all open components now?
03:08
<
akaizen >
bootrom -> u-boot-spl.bin -> uboot.bin -> boot.img -> rootfs?
03:09
<
akaizen >
flash with rkdeveloptool ?
03:09
<
hanetzer >
yep. though atm boot.img (which is any sort of image u-boot can handle) can only come from emmc (and maybe sdcard)
03:09
<
hanetzer >
erm, spi flash
03:10
<
akaizen >
hoping emmc works: [22:03:55] <vagrantc>akaizen: u-boot v2018.01 works
03:27
<
hanetzer >
I actually had to send the O.G. kernel/initramfs over to the asus c201 via ymodem :P
03:51
<
akaizen >
hanetzer: dats some og stuff right there
04:18
<
akaizen >
hanetzer: dude thats for the heads up on mr24.. i think this will be super helpful for another project im workin on
04:18
<
akaizen >
ran into the co-founder of meraki at a conference so maybe this is a sign :)
04:19
<
hanetzer >
heh, glad to have helped on that. they're not the best, but if you can find them for $10-20 a pop, who cares? :P
04:20
<
akaizen >
the fundamentals are whats important :)
04:20

you can always improve speed later
