[SOLVED][Odroid-U3] How-to modify kernel parameters

[AlexisTM]

Dear sirs,

$this->bbcode_second_pass_quote('', 'E')DIT: for a perfectly clean boot with NO messages, use loglevel=-1
Working but I don't know if it is good to do

[mikmakmuk]

Create a boot.txt in /boot with the following content
$this->bbcode_second_pass_code('', '
setenv fdt_high "0xffffffff"
setenv drm_video_mode "HDMI-A-1:1920x1080M@60"
setenv bootcmd "fatload mmc 0:1 0x40008000 zImage; bootm 0x40008000"
setenv bootargs "video=${drm_video_mode} console=tty1 console=ttySAC1,115200 mem=2047M fbcon=map:1111111111111111111111111111 root=/dev/mmcblk0p2 rootwait rw quiet loglevel=0"
boot
')

Then create a boot.scr with
$this->bbcode_second_pass_code('', '
mkimage -A arm -C none -T script -n 'Boot script for quiet ODROID-U3' -d boot.txt boot.scr
')

That *should* work, is however untested.

Thanks a lot, it is working!
(For next users who have same questions)

boot.txt
$this->bbcode_second_pass_code('', 'setenv fdt_high "0xffffffff"
setenv hdtv_type "dvi"
setenv hdtv_format "1080p60hz"
setenv bootcmd "fatload mmc 0:1 0x40008000 zImage; bootm 0x40008000"
setenv bootargs "console=tty1 console=ttySAC1,115200n8 hdtv_type=${hdtv_type} hdtv_format=${hdtv_format} root=/dev/mmcblk0p2 rootwait rw mem=2047M quiet loglevel=0"
boot')

$this->bbcode_second_pass_code('', 'mkimage -A arm -C none -T script -n 'Archie quiet OdroidU3' -d boot.txt boot.scr')

Now, I have still a problem to hide the [ OK ] messages. I tried to use Plymouth (like one the RasPi) but it didn't worked.
Nothing happens even when I do
$this->bbcode_second_pass_code('', 'plymouthd; plymouth --show-splash; sleep 10; plymouth --quit')
But It will be another subject!

Thanks again mikmakmuk!

[OK] comes from console=tty1 (which I personally like)

[AlexisTM]

I also like it! For personal usage...

But on a KIOSK, this frighten the client...

[WarheadsSE]

OMG it said OK!

(just remove the 'console=tty1' bit)

[AlexisTM]

Dear,

I tried without the console=tty1 in boot.scr and by adding initrd=initrd.img but [ OK ] messages are still showed and Plymouth is not showing even if we can read " [ OK ]Started Show Plymouth Boot Screen."
I will create a new subject, it is a bit far of the initial title!

setenv bootargs "console=ttySAC1,115200n8 hdtv_type=${hdtv_type} hdtv_format=${hdtv_format} initrd=initrd.img root=/dev/mmcblk0p2 rootwait rw mem=2047M splash quiet loglevel=0"
