<projectgus> is there documentation somewhere on how the bootloader internals with the internal & external SDs?
<projectgus> does it just look @ 1k offset on each for something it can execute, or is it more complex?
<projectgus> or will it only ever boot the internal SD?
<abrasive> it's 1k and internal
<abrasive> no external (it's a strap but i don't think we can access it)
<abrasive> only alternative is usb, which it falls back to.
<abrasive> see tools/imxboot in the u-boot tree
<projectgus> ah i saw your note about that
<projectgus> so a gk802 can act as an OTG device?
<abrasive> yeah
<abrasive> but the host and device ports are wired together
<projectgus> right
<abrasive> and i couldn't convince a kernel to switch between modes either
<projectgus> madox on the sydney hackerspace list mentioned that
<projectgus> he plugged something into the A port while powering it from his computer, and the device enumerated on the PC not the GK802
<projectgus> seemed... risky :)
<projectgus> imxboot must be nice for uboot development though
<abrasive> i didn't spot the gk802 conversation there.
<projectgus> no juggling sd cards -> happy days
<abrasive> is that robodino or another list?
<abrasive> yeah, absolutely
<abrasive> i was so pleased when i wrote imxboot
<projectgus> thread was called "Raspberry Pi Alternative" I think
<abrasive> after getting very grumpy juggling cards
<projectgus> oh you wrote it? nice
<abrasive> the internal slot is a pain
<projectgus> yeah, i didn't realise the internal flash was an sd card
<projectgus> it's kind of neat for my purposes, hoping I can run two SD cards as a raid-1 device
<projectgus> for (hopefully) extra reliability
<abrasive> there's an issue at the moment where heavy load on the MMC starts blocking everything else
<abrasive> i gather it happens on other embedded linux systems too.
<projectgus> all other io operations, or all other anything?
<abrasive> ssh gets laggy.
<abrasive> badly.
<abrasive> i haven't tried in a while, have been working on yocto stuff on my build machine recently
<projectgus> interesting
<projectgus> do you have an opinion on the rubber thermal pad on the cpu, btw?
<projectgus> is it as good as a proper heatsink would be?
<projectgus> i've never seen anything like it
<abrasive> it's a bit odd.
<abrasive> but seems to work fine
<abrasive> mine has a bit of thermal paste on it now
cnxsoft has quit [Quit: cnxsoft]
<abrasive> it gets a bit mangled if you're doing lots of internal dev
<abrasive> the thermal throttling on the cpu means it's stable without (!)
<projectgus> ah cool, i was just about to ask
<abrasive> as long as you have an up-to-date kernel anyway
hste has joined #imx6-dongle
<hste> abrasive: have u tried this temperature patch? https://community.freescale.com/docs/DOC-94582
<abrasive> nope... i don't really care about the temperature tbh :)
<abrasive> (also i'm not currently booting kernels on my dev)
<hste> :)
<projectgus> hi hste
<hste> abrasive: how does it go with the uboot? Are u and jas_hacks ready for relasing a verison on git?
<projectgus> I noticed a typo in your 1204 flashing script btw, the bs= is missing from the 'dd' line for the kernel
<hste> ok
<projectgus> fwiw I really recommend using 'set -e' around any operation that might fail like that
<projectgus> especially if stderr is redirected to null
<abrasive> hste: i'm waiting to hear back about the patch
<abrasive> hometime! bbl.
<hste> projectgus: fixed the dd typo. thanks
<projectgus> hste: :)
<projectgus> off to hopefully give my gk802 it's first boot to ubuntu
<hste> projectgus: a new uboot is soon to come that uses a boot.scr. Makes it easier to switch between sdcards/usb

<projectgus> hste: thanks. is it waiting on actual code changes, or should I be able to build such a repo myself from the uboot git repo?
<projectgus> abrasive: i see what you meant about mmc blocking everything. I ran a dd if=/dev/zero in my home directory, whole thing became unresponsive
<projectgus> ionice made it almost usable but there will still pauses, I think when it was syncing
<projectgus> mmcqd kernel task just owning an entire CPU, seems to lock everything out
<projectgus> I wonder if USB I/O is as bad
<projectgus> hste: i mean "such a uboot myself", obviously :)

<projectgus> abrasive: very nice with the gk802 uboot
<projectgus> so empowering!
hste has quit [Ping timeout: 240 seconds]
<abrasive> yeah, it is pretty solid
<abrasive> i think once mmc is sorted
<abrasive> it'll be pretty usable.
triplelexx has joined #imx6-dongle
<triplelexx> I'm not having much luck running the hste gpu_vpu scripts, I don't get boot of any kind
<triplelexx> file system seems fine, device boots android
<abrasive> serial console connected?
<triplelexx> no
<triplelexx> with a serial cable?
<triplelexx> or over usb you mean?
<triplelexx> don't know how to do debugging
<triplelexx> blue light is on screen is black, as technical as it gets atm..
<triplelexx> ok, made it again without scaling
<abrasive> with a serial cable... you'd have to solder it in
<triplelexx> yeah still nothing
<abrasive> what exactly is your hardware?
<triplelexx> gk802
<triplelexx> blue one
<abrasive> what part of it is blue?
<triplelexx> the whole board
<abrasive> oh right.
<abrasive> where are you sourcing your image (or image parts)?
<triplelexx> hste script
<triplelexx> from jas blog link
<triplelexx> it downloads it all automatically
<abrasive> okay. could try this by hand
<abrasive> might not get anywhere without a console though
<abrasive> what are you using as a display?
<triplelexx> tv
nicksydney has joined #imx6-dongle
<triplelexx> panasonic
<abrasive> er
<triplelexx> and swap with my version?
<abrasive> just put it straight on the card.
<abrasive> dd if=u-boot.imx of=/dev/sdc bs=1k seek=1 - where sdc is your card reader!
<abrasive> i think the script overwrites the files if you run it again.
<abrasive> this u-boot defaults to pop a splash screen.
<triplelexx> ok I'll try that
<triplelexx> black screen
<triplelexx> i got the oneric image to work, but since then nothing
<abrasive> one wonders if your hardware differs.
<abrasive> have you tried the android u-boot with hste's image?
<triplelexx> more likely being a noob
<triplelexx> ohh i have vga images
<triplelexx> !!
<triplelexx> i ran upgradekernel.sh and now at least see something
<triplelexx> think it'd still be using your uboot though
<triplelexx> but has launched into desktop
<abrasive> winner.
<triplelexx> hmm yeah says display is laptop and locked to vga res
<abrasive> then it's not reading the EDID info from your display.
<abrasive> probably - depending on which kernel it is anwyay...
<abrasive> can you find /sys -name *edid* ?
<triplelexx> is that a command?
<triplelexx> you mean
<triplelexx> yeah the kernel i loaded is from march
<triplelexx> so not sure that's right anyway
