mmind00: do you test if sound works?
<mmind00>
macc24: not really ... my boardfarm doesn't have any sound-specific setup ... so in terms of multimedia the core display is the one thing I do test regularly
<macc24>
mmind00: i hear sound's broken on veyron... need to bisect
<mmind00>
macc24: also, the speakers on my veyron test-device gave up their magic smoke years ago [it even smelled aweful], when some sound thingy went haywire
<macc24>
mmind00: what if u hook up an led into those speakers
<macc24>
and put that alongside screen so u can see if speakers are working
<mmind00>
macc24: too complex ... my boardfarm is actually a separate entity, where the display for example goes to a hdmi muxer device which in turn runs to an external monitor and the serial console comes through a web-interface ... I don't physically touch / see devices when doing tests
<macc24>
guess i'll solder new clip onto old cables lol
<macc24>
i've got to build a proper programming board for stm32 bluepill...
<macc24>
alpernebbi: full rom image booted up \o/
<alpernebbi>
it doesn't boot a kernel for me tho
<macc24>
what are you trying to boot that kernel with?
<alpernebbi>
extlinux.conf from u-boot-menu debian package
<macc24>
odd
<alpernebbi>
I mean it works from U-Boot in RW_LEGACY and U-Boot in the kernel partition, but not as full rom, it just gets stuck at "Starting kernel..."
<alpernebbi>
did it boot into an OS for you
<macc24>
i'll experiment around
<alpernebbi>
thanks
<macc24>
did you compile in support for chromeos kernel partitions?
<alpernebbi>
not into u-boot, no
<macc24>
._.
<macc24>
uh, i think i left stove on at home
<alpernebbi>
But I'm not trying to boot from chromeos kernel partitions anyway?
macc24 has left #linux-rockchip [WeeChat 2.8]
<alpernebbi>
It's meant to be an ordinary distro boot
<alpernebbi>
I mean it does load kernel/initramfs/dtb just fine, I think I'm getting a early kernel panic
macc24 has joined #linux-rockchip
<macc24>
jokes aside i'll try booting something linux on it
<macc24>
hmmm early kernel panic
<macc24>
alpernebbi: do you know if u-boot adds simplefb node into device tree?
<alpernebbi>
I think there's a config for it that I did not enable
<macc24>
...
<macc24>
alright i'll compile u-boot for kevin myself
<alpernebbi>
configs/chromebook_kevin_defconfig to be precise, I do commit whatever I need into it
<macc24>
okay
<macc24>
alpernebbi: bootefi doesn't work too
<macc24>
`bootefi hello`
<alpernebbi>
would be easier to debug with a servo :p
<macc24>
or at least with uart....
<alpernebbi>
yeah
<alpernebbi>
macc24: CONFIG_CMD_BOOTEFI_HELLO is not set btw
<alpernebbi>
unless you set it yourself
<macc24>
alpernebbi: i compiled my own build
<alpernebbi>
I had tried `bootefi selftest` and remember it showing only a network error
<alpernebbi>
do tell if you see any good options I should have enabled
<macc24>
alpernebbi: fyi veyron kpart boots with no display
<alpernebbi>
which veyron was it
<macc24>
minnie
<alpernebbi>
great, thanks for testing :D
<alpernebbi>
I'm assuming the display is something with u-boot and not about how I put it into the kpart :P
<macc24>
theoretically yes
<macc24>
depthcharge might be leaving display controller in weird state
<macc24>
with u-boot not kicking it into whatever it expects
<alpernebbi>
understandable

<macc24>
alpernebbi: so far i can say "i have no idea"
<alpernebbi>
same
<macc24>
mmind00: ???
<macc24>
any ideas why u-boot can't boot anything on a rk3399 device?
<alpernebbi>
macc24: also, not urgent but I'd be glad if you can test minnie.cbfs as RW_LEGACY
<alpernebbi>
(I'll go sleep soon)
<macc24>
good night
<alpernebbi>
thanks again
<mmind00>
macc24: that would need more information ... i.e. my rk3399-puma board has an uboot 2021.10 I think ... so uboot works ;-) ... and my Gru-Kevin does use Coreboot reflashed to do only netboot - so no uboot there
<macc24>
mmind00: that puma board, what config does it have?
