@phh : i'm stuck with that image. tried a lot of things and i can't get it to boot. i folowed the full procedure that's on the rk repos ... but it won't boot. just get a black screen
<wzyy2>
So it looks like your system is up, just hdmi have been broken.
<phh>
LongChair: your plugging it to a tv or a pc monitor?
<phh>
you're
<wzyy2>
The image created from build script also have a FAT partition and then an ext4 partition, but the boot partition is marked as EFI, so it won't be shown
<LongChair>
@phh : it's a tv
<LongChair>
@wzyy2 : any idea of what could break hdmi ?
<LongChair>
@wzyy2 : if i flash the system.image that comes out of build script ... it doesn't even start to boot
<LongChair>
hehe yeah that looks like what it's complaining about :)
<LongChair>
i'll try that on the ASUS image
<wzyy2>
It seems your screen require a 4k-60hz display mode which is not yet supported in linux.
<LongChair>
i see
<LongChair>
@wzyy2 : works ! awesome thanks ! :)

hi does mmc works in your uboot tree?
<mrjay>
i can't get it up on rk3066
<mrjay>
sorry wrong window
<mrjay>
mmind00: ^
<mmind00>
mrjay: never tried so far ... I've only used tftp so far ... but keep in mind, the mmc handling is also different in the kernel between rk3066/rk3188 and the newer socs
<mrjay>
ahh ... i didn't know that
<mrjay>
mmind00: i need to investigate more ... but usb works out of the box
<mrjay>
mmind00: when you'll have time ... please test mmc and post here if it works

earlyprintk is enabled. is there way to debug boot process?
<Myy>
AFAIK, the other way is to connect an UART<->USB cable and use minicom, in order to see any string that will output by the kernel (given the current kernel's loglevel).
<Myy>
There might be other ways involving TCP/IP debuggers, but I have no idea how to use them.
<Myy>
Anyway, I'll have to go. If nothing work, but you have the DTB of your board, you can give https://github.com/Miouyouyou/MyyQi a try. You might have kernel panics about the root partition mmc0blkX becoming mmc1blkX though.
<Myy>
However, a few extlinux.conf changes should solve the problem, if that's the case.
<Myy>
See you everyone !

I already use serial console, but last message is "Starting kernel ..." from u-boot
<mmind00>
k_: I guess at first making sure that it's the correct debug_ll settings in the config?
<k_>
earlyprintk should use u-boot's console
<mmind00>
k_: while somewhat true, you still need to tell the kernel where to put stuff and thus need to enable a correct DEBUG_LL setting
<mmind00>
k_: DEBUG_LL for 32bit of course, 64bit requires an earlycon as base
