xdarklight: sorry, sleep intervened
<mace>
xdarklight: i had assumed flash storage was something that was old hat in the kernel by now o.o
<mace>
will check what's on this board
<mace>
has a samsung KLMBG2JETD 32Gb eMMC flash chip on it
chewitt has joined #linux-amlogic
<xdarklight>
mace: eMMC is supported (even with full capacity) while NAND (insert multiple disclaimers here ;))
<mace>
xdarklight: ah happy days :)
<mace>
xdarklight: happy to test patches etc once I figure out how to get buildroot working
<xdarklight>
mace: not sure which patches you are speaking of. eMMC is supported upstream and *should* not need any patches to make it work
<chewitt>
mace: what are the dev boards (brand/model) ?
<chewitt>
the A311D and S905D3 combo sounds like Khadas VIM3/VIM3L
<chewitt>
in which case it should be trivial to use them, they are well supported
<mace>
these are from 'sztomato'
<chewitt>
do you have schematics? .. do you have u-boot/fip sources?
<chewitt>
Shenzen Tomato are a known name
<mace>
i have virtually nothing. they sent me these, and then after i got them asked me if i'd like to spend 3k usd + sign an nda for the sdk etc, and i wasn't wildly desperate to do either
<mace>
i've a single word document for one of the boards i can send over if you want to eyeball it and see if it's of any use?
<chewitt>
sure .. always happy to look
<chewitt>
share a dropbox link or similar, or pm for an email
<mace>
test platform for a custom board, for the most part
<mace>
however if these boards are half decent, i might import some and sell them in the uk
<mace>
as a side line
<mace>
wanting to run android on them, mipi dsi display, i2s audio output, i2c control of a parent board for a car head unit
<mace>
maybe have a functioning microsd slot for users to stick music etc on, ditto usb for usb sticks. not exactly high brow stuff
<chewitt>
the overall plethora of interfaces on the board kind of forces you to use the bsp kernel
<chewitt>
current mainline support is geared towards HDMI output and Android TV/box configurations
<mace>
understandably i guess
<Xogium>
what about odroid n2 ? How is it doing so far ? Been thinking of getting one
<mace>
i don't need all of those interfaces on the board working, just the key ones. however it turns out this board might not expose mipi anyway
<mace>
i did look at the n2, but it definitely doesn't expose mipi dsi - i asked
<Xogium>
but I don't want to use a 4.9 kernel
<Xogium>
like, is it good to run usb and headless ?
<mace>
i've not physically used one
<Xogium>
hmm
<Xogium>
I tried to read through the wiki to determine the mainlining progress but there's tons of stuff I don't understand
<chewitt>
N2 is well supported
<Xogium>
yeah, already ? That's nice
<chewitt>
boots fast, esp. with an emmc module
<chewitt>
half the product is a heatsink so cooling isn't an issue
<Xogium>
all I care about really is headless stuff. I remember my c2, I used it as soon as there was initial support in mainline hehe that was perhaps a bit too hasty ;)
<chewitt>
(not that cooling is really an issue on any devices)
<chewitt>
C2 works well for me when I test things
<Xogium>
yeah, its a very neat board
<Xogium>
at one point I amused myself with the buggy sensor data for thermal, said 40.5 million degrees and I went like, cool ! Lets start nuclear fusion
<chewitt>
I use the Khadas boards most, but that's mostly because I can have one PSU on the desk and do all the major Amlogic SoCs
<Xogium>
my first arm board was the c2
<chewitt>
everything else requires a smorgåsboard of PSUs
<Xogium>
then I took an espressobin from globalscale, which runs quite good, but its not at all oriented like the c2 was. The n2 might be my third, especially if I can somehow use the eMMC I had in my c2 for it
<Xogium>
I had the black module for the c2, 64 gb
<chewitt>
I'm not sure the modules are compatible, but that's a Q for the HK forums
<chewitt>
I use whatever they post me, which seems to be a bit random somtimes :)
<Xogium>
yup. Do hope they are though, eMMC is definitely priced high
<Xogium>
I know you couldn't use the eMMC for c2 in a xu4
<Xogium>
which was kind of funny, samsung eMMC not working on a samsung SoC
<Xogium>
but the xu4 eMMC worked in a c2
<chewitt>
I'm using the same (orange) modules on a C1+, XU4 and C4 .. because they sent three modules in the same bag
<Xogium>
did they now ?
<chewitt>
all were pre-formatted for XU4
<chewitt>
I'm sure things are more organised for customers, these were all samples for dev/upstreaming work
<Xogium>
ahah yeah
<Xogium>
most likely are
<Xogium>
I do wonder though if the n2 could be used as a decent build machine
<chewitt>
mace: the biggest challenge you'll have is the fip sources for boot firmware
<Xogium>
all I have here is a poor core i5 of third generation which has some trouble cooling down, even while idle. Around 50C
<Xogium>
so often when building things it goes up beyond 90C
<chewitt>
one of the LE contributors has been cross-compiling images on a VIM3, N2 and RK3399 recently
<Xogium>
neat
<chewitt>
build times are about the same as my older (2011) Core i7 MacBook Pro 13"
<chewitt>
sorry.. older Dell Corei7 laptop
<chewitt>
MacBook is about 1/2 the time of the Dell
<Xogium>
wow, not half bad considering the boards
<chewitt>
about 4.5 hours for N2
<Xogium>
I know building a kernel on my c2 took about 3 hours
<Xogium>
but while I was doing that I couldn't do much of anything else because for some strange reason my usb keyboard started acting up and some keys were repeated several times when typing on irc for example
<Xogium>
while having a compilation running
<chewitt>
I am ruined by an AMD 2990WX .. full distro image from sources in 22 mins :)
<Xogium>
oh wow
<chewitt>
and 1/3rd of that is sequential building bits of toolchain
<Xogium>
heh
<Xogium>
from my experience when building full systems here, most of the time it takes is actually on running configure
<Xogium>
that is, make is parallel but configure isn't
<chewitt>
LE builds host compile packages that build the ARM toolchain that's used to build everything else
yann|work is now known as yann
<chewitt>
so the initial period is sequential building toolchain bits
<Xogium>
yeah like buildroot, sort of
<chewitt>
then it goes massively parallel
<Xogium>
buildroot finally got experimental support for top level parallel build, which is a relief
<Xogium>
building this system here went from a full hour to around 20 minutes
<Xogium>
I just wish the cpu would not heat up so much lol
<chewitt>
I'm still stunned at the server/box that I have
<Xogium>
the server I have here isn't something where I have physical access, but its a neat machine
<chewitt>
under a full compile load with all cores saturated you can put your head against the case and you still can't hear anything
<Xogium>
oh wow
<chewitt>
it sits in the corner of a room with a hamster cage next to it .. the hamsters make more noise than the server
<chewitt>
nvme ssd so there's nothing spinning in the case apart from some large noctua fans, which are silent
<Xogium>
I pay 65 usd every month for it, but it's worth the price. At least, I didn't find any other provider that does as much, and as well so far. dual xeon l5639, 24 gb ram and 2x 1 tb drive, 5 public ip, 24/7 ipmi over serial, 24/7 support and 20 tb bandwidth each month
<chewitt>
which provider?
<Xogium>
ioflood
<Xogium>
they have servers on their website, but if you contact them and explain what you want to do, your budget and etc. they generally make you at least two offers that are custom, and that for as long as you keep the server you'll pay the same price and it won't increase
<Xogium>
also the ipmi is usually some kind of java crap, like a kvm
<Xogium>
but since I mentioned that I was blind they put it in serial mode, no question asked. That's the only provider who did that for me so far
<Xogium>
cause really, the java stuff sucks for usability with a screen reader
<Xogium>
I checked at things like digital ocean too, before, but well, their largest vps is 80 usd a month, and it's at least 3 times less powerful than this dedicated one that I pay $65 for
<Xogium>
there's a bit of latency and stuff since I'm in france and they are in arizona, but if latency over ssh is the price to pay to keep this neat machine, then I can't complain too much about it :D
<chewitt>
we host most of our stuff at DO, but performance is only one of our requirements
<chewitt>
it's easy to beat them on that
<chewitt>
but overall it's one of the better build platforms, and simple to manage
<Xogium>
yeah, that's a bit meh since they cost quite a lot
<chewitt>
as long as $donations > $expenses I'm not fussed :)
<Xogium>
hah yeah
<Xogium>
I've been thinking about making something to sell actually, but its still very vague in my mind at this point
<Xogium>
but I want to make some kind of music player that is fully vocalized via tts, that can also read text files via tts and some other things, and sell them
<Xogium>
there is already one such thing, but they sell it for $900

I always had this idea that somehow if I could produce one that does as well at this job, or possibly even better, for a lower price, then I'd end up selling more of them, and getting more in return. Seems logical to me, but what do I know really
<Xogium>
also because I'm a bit tired of always having to pay tons of money for things made for the blind
<chewitt>
i'll be honest, I'm very ignorant about visually impaired access on Linux things
<chewitt>
I suspect LE/Kodi could be improved
<Xogium>
I honestly don't know
<Xogium>
I know there's a screen reader for kodi
<mace>
chewitt: fip sources for boot firmware?
<Xogium>
but its one thing I never actually used
<Xogium>
but I was more thinking of a small embeded device that could fit in your pocket
