When yu do bootm u-boot will relocate the content to the given load address in the uimage
<Gottox>
ah, there comes the loadaddress from.
<sjoerd>
yes
<javier__>
Gottox: that's why you need to use a different (u-boot) load address than the kernel load address / entry point
<javier__>
Gottox: I use 0x42000000 for example
<Gottox>
aaaah.
<Gottox>
but the build progress itself is okay?
<javier__>
Gottox: it depends, I use an appended DTB while you are creating an uImage with no appended DTB
<javier__>
so you need to also load the DT and pass it to bootm
<javier__>
I didn't see that in the u-boot command that you shared
<Gottox>
aah, so that's my mistake.
<javier__>
Gottox: as I said, I would just use a zImage instead of a uImage
<javier__>
but that is a separate thing
<Gottox>
yea, but for tinkering around uImage is enough for now. Will change that later.
<Gottox>
thanks guys, that was really helpful!
<javier__>
Gottox: yw
<javier__>
Gottox: btw, I see you are building a mainline 4.0.5 but you should really use 4.1
<javier__>
Gottox: with 4.0.5 you won't have display and wifi working
<Gottox>
javier__: yea, I already did that after reading the backlog, thanks :)
<javier__>
nor Suspend-to-RAM, HDMI and there are several important bugs that were fixed too
<javier__>
Gottox: great
<Gottox>
kindof success: the device resets, but the screen flickers so I suspect the fb drivers get loaded.
<javier__>
Gottox: which kernel version? 4.1?
<Gottox>
4.1
<Gottox>
yes
<javier__>
Gottox: and you are using a mainline u-boot?
<Gottox>
both vanilla, uboot and kernel.
<javier__>
and exynos_defconfi... mmm that should really work
<Gottox>
yea, I suspect I made a mistake somewhere, will retry later.
<javier__>
Gottox: ok

any ideas on why sound doesn't work on snow? I get a too fast playback rate and can only hear the headphone amplifier turning on/off when mixer levels are high.
<john_f>
using linus 4.1 kernel
<javier__>
john_f: sound is the only peripheral that is not working correctly. I took a look a couple of times but didn't figure out what's missing
<javier__>
john_f: there are reports of audio not working correctly on other Exynos machines due a bug in the pl330 dma driver
<si1v3r>
javier__: Is the sound system the same for snow and peachpit? My sound works fine.
<si1v3r>
I did have to do the whole right mixer speaker right on madness...
<javier__>
si1v3r: same codec chip but different wiring at the board level
<si1v3r>
Oh so I just lucked out then. :)
<javier__>
si1v3r: yeah, I have some patches to add UCM profiles for Snow and Peach Pit/Pi but never posted...
<si1v3r>
was the sleep resume patch merged in time for 4.1?
<si1v3r>
if so I may build it.
<javier__>
si1v3r: no it wasn't... unfortunately it was too late for the 4.1 -rc cycle
<si1v3r>
too bad. Well 4.2 is looking hopeful then.
<si1v3r>
I've got a exynos laptop with sound, sleep, wifi... life is good. :)
<javier__>
si1v3r: about sound, I'm not completely sure what's missing. I had audio working on peach and snow at some point with some patches from Samsung that I re-posted
<javier__>
but many people says that it does not work on Snow and I was able to reproduce one time but don't remember with what u-boot version, etc
<javier__>
si1v3r: hehe, yeah is good that the exynos chromebooks work much better now with mainline
<si1v3r>
Really wonderful. It's a real option for a non-x86 workstation now.
<si1v3r>
You've preserved the hardware too, since upstream support from goosung is no longer required.
<si1v3r>
Better than wintel was, but still... :)
<javier__>
I still have ChromeOS on my emmc though
<javier__>
I'll leave it until I have mali and proper 3d hw acceleration working :)
<si1v3r>
fbdev is fine for me. I mostly text edit.
<javier__>
es, fbdev works well indeed for that
<javier__>
*yes
<javier__>
si1v3r: IOMMU and CPUFreq are the two big things that are still missing
<javier__>
probably the former is not too important for your use case but certainly the later is
<javier__>
hopefully both could make it for 4.3 though since the patches have been in the list for months
