sjoerd: Hi!
<ezequielg>
I'm trying to get u-boot mainline to work on rk3288
<ezequielg>
is it possible to prepare an sdcard and be able to boot the soc?
<ezequielg>
or do i need to run the rkflashtool step each time?
<sjoerd>
hey
<sjoerd>
no you can prep an SD card and boot from that
<sjoerd>
but it will always first try the eMMC
<sjoerd>
This is assume you have a board with eMMC
<sjoerd>
which board is it ? :)
<ezequielg>
good ol firefly
<sjoerd>
I don't know if that has poitns or a jumper to disable eMMC
<ezequielg>
so... i'll just wipe emmc and the bootrom is smart enough to try sd card?
<sjoerd>
but you can do rkflashtool b 3 in recovery mode to maek it skip the eMMC
<sjoerd>
indeed
* ezequielg
tries that
<ezequielg>
btw, the README.rockchip is confusing me: the u-boot-spl-dtb.bin is 36 KiB, but supposedly the bootROM can't load more than 32 KiB... how come?
<sjoerd>
there is a 4k header iirc
<sjoerd>
oh wait
<sjoerd>
you mean before or *after* you ran mkimage ?
<sjoerd>
the SPL is very very much on the edge
<sjoerd>
it's too big if i build it with gcc 4.x and just the right size with gcc 5.x for me
<sjoerd>
mkimage will complain if it's too big
<ezequielg>
afaiu, before
<ezequielg>
i'm just doing make something_defconfig && make
<ezequielg>
and u-boot-spl-dtb.bin is 33037 bytes
<ezequielg>
maybe i need a better toolchain then?
<sjoerd>
well try mkimage and see if it complains :P
<sjoerd>
I actually have a todo item to see if i can cut something out because ti's causing problems for me as well :/
<sjoerd>
ezequielg: on my gcc 5 build it's 32657 bytes
<ezequielg>
what toolchain are you using?
<sjoerd>
so yeah it's rather cutting it close
<sjoerd>
ezequielg: cross-compliers from debian unstable
<ezequielg>
ok
<sjoerd>
iirc sjg mentioned he had a hacked up gcc
<ezequielg>
yeah, mkimage is complaining
<ezequielg>
:/

I bet ther eis something in the SPL that can still be turned of
<naobsd>
let's follow rk3036 way...
<naobsd>
btw my spl bin is 28708 bytes
<naobsd>
oh strange
<naobsd>
ah
<naobsd>
spl-dtb.bin is 32513
<ezequielg>
sjoerd: i'm trying to remove some stuff, but i'm unable to get anything quick and dirty to work... guess it needs some closer inspection
<sjoerd>
naobsd: yeah i think sjg might have been overly keen in going for the full fdt usage in the SPL :)

mmind00: quick question - nothing in the kernel should have changed sound, should it? (trying to get audio to work, and not having much luck getting it to go, so just checking this before I go try to figure out these UCM files)
<mmind00>
pulser: right, but I also don't know if anyone got that working on mainline at all yet
<pulser>
ah OK - good point
<mmind00>
pulser: last time I tried, my speakers smelled awful after that
<pulser>
I didn't see any device nodes, so that may well be something not yet working
<pulser>
there is also powerdomain stuff set for it, which could potentially be relevant (audio-supply appears to be set)
<mmind00>
io-domains != power-domains :-)
<pulser>
ofc; what I was thinking was we could have a repeat of mali, where it was there, and "off" or something :)
<pulser>
I see caesar has a few things about I2S on the list - so it looks like it's still wip

mmind00: can the rockchip chromebooks overpower their speakers again?
<mmind00>
sjoerd: it looks like it .... when I tried to play with alsa-options the last time, it started to smell at some point
<mmind00>
sjoerd: again? ... did earlies Chromebooks do that as well?
<sjoerd>
yeah it's a known issue on the snow (first arm chromebook) that it can fry its speakers
<mmind00>
a least now it stopped to actually smell up my flat ;-)
