10:27 vpeter> What a nice looking: https://www.solid-run.com/wp-content/uploads/2018/02/CuBox-Pulse-1024x683.png
10:31 Ke> sure
10:31 Ke> how many cores?
10:31 Ke> also, what peripherals
10:37 topi`> jnettlet[m]: while you're close to the Arrow booth, try to get a Dragonboard 820 ;)
10:37 topi`> I tried to buy from arrow's website, but nothing but a query form
10:38 topi`> vaporware sucks
10:51 jnettlet[m]> I have one already
10:52 topi`> I want it for its pretty decent floating point perf
10:52 topi`> unmatched by any other ARM boards
10:53 topi`> well maybe the new Exynos chip will be better ;)
10:53 topi`> Exynos hasn't actually been very linux-friendy
10:53 topi`> even Hardkernel seems to have gone over to other vendors, like Amlogic
10:54 topi`> Ke: the i.mx 8M parts are all quad core a53's
10:54 topi`> which is just fine as long as the other parts are improved (i.e. bus bandwidth, DRAM, especially gigabit ethernet ;)
10:55 topi`> also the GC2000 graphics is pretty long in the tooth
10:56 Ke> I don't know that expression
10:56 Ke> but I know people have been developing open source drivers here
11:02 topi`> Lucas from Pengutronix is already working on GC7000 drm
11:04 Ke> also, I'll be moving in 30.4. so mcbin should go to production before that
11:04 topi`> are you moving abroad?
11:05 Ke> no to lauttasaari
11:05 topi`> short distance then :)
11:05 Ke> yup
11:05 topi`> my mcbin is situated in Nebula's server room
11:05 topi`> but it needs a new kernel, badly
11:05 Ke> heh, actually very close to that
11:05 Ke> I can go poke it locally, if you want
11:05 topi`> thanks :)
11:06 topi`> yeah, sometimes it needs a reboot if a kernel update is botched
11:06 topi`> I'd like to implement an altbootcmd mechamnism for uboot so that it can try to load the older kernel if watchdog bites
11:06 topi`> otherwise I'll be blindly testing a new kernel ;)
11:06 topi`> since I don't have another mcbin at my disposal :(
11:07 topi`> SR should make an el-cheapo version of mcbin by changing to the 7040 SOC which has less interfaces, but similar characteristics overall and possibly the same motherboard layout
11:08 Ke> I would just hope the default uart would be available as a ttl header
11:08 Ke> though outside of the very early boot, you can modify the booloader
11:13 topi`> the default uart comes via a usb bridge chip, which is nice. I can then hook a Raspberrypi to control mcbin's console
11:14 topi`> add magic sysrq to the kernel and you can even boot mcbin via the uart
11:14 topi`> I installed a Rpi next to mcbin, gave it a static IP, but now it no longer responds to that IP so I assume it is dead. I should have shipped an old Hummingboard instead.
11:15 topi`> "hummingboards live forever"
11:38 wumpus> yes :)
11:45 suihkulokki> whee, i.mx8 materializing
11:47 Ke> does it come with unsigned bootloader and moderately free ATF?
11:48 wumpus> ATF?
11:49 suihkulokki> arm-trusted-firmware
12:03 wumpus> oh, wouldn't know about that one
