[SOLVED] Regression

Unread postby facotl » Wed Jul 18, 2018 5:00 am

Hello,

If you look at the end of this post, there is a regression with display on C2 with VU7+ for the Ubuntu 18 minimal image.
viewtopic.php?f=141&t=29262

Colors on startup that were fixed are again a problem.


Thank you for your help.

Hi facotl,
Sorry for making this inconvenience.
To remove the color issue, you need to update u-boot.

I need to make a common approach to cover all of resolutions and dvi/hdmi switching logic for logo display mechanism,
but still it's not applied yet on released u-boot version.

So could you update the attached u-boot again?
Please find "c2_vu7+splash_20180720.tar.gz".

Copy the file in FAT file system of your C2 emmc card,
then extract items and write them using sd_fusing.sh
Code: Select all
(copy the tar.gz file in /media/boot and boot the C2 system)
# cd /media/boot
# tar xvfz c2_vu7+splash_20180720.tar.gz
# cd ./sd_fuse
# ./sd_fusing.sh /dev/mmcblk0
( and reboot )

The u-boot version is
Code: Select all
odroidc2#ver

U-Boot 2015.01-dirty (Jul 20 2018 - 14:14:43)
aarch64-linux-gnu-gcc (crosstool-NG linaro-1.13.1-4.9-2014.09 - Linaro GCC 4.9-2014.09) 4.9.2 20140904 (prerelease)
GNU ld (crosstool-NG linaro-1.13.1-4.9-2014.09 - Linaro GCC 4.9-2014.09) 2.24.0.20140829 Linaro 2014.09


And also you can find an example of boot.ini to fit in VU7+ display.
attachment : "boot.ini.zip"
Here are modification points I've adjusted.
Code: Select all
# Auto Detection of Monitor settings based on your Screen information
# See: http://odroid.com/dokuwiki/doku.php?id=en:c2_auto_detect_display
setenv display_autodetect "false"

# setenv m "1080p60hz" # Progressive 60Hz
setenv m "1024x600p60hz"

# HDMI DVI/VGA modes
# By default its set to HDMI, if needed change below.
# Uncomment only a single Line.
setenv vout "dvi"
# setenv vout "vga"

setenv logoopt "osd1,loaded,0x3f800000,${m}"

setenv bootargs "root=UUID=e139ce78-9841-40fe-8823-96a304a09859 rootwait ro ${condev} no_console_suspend logo=${logoopt} hdmimode=${m} ${cmode} m_bpp=${m_bpp} vout=${vout} fsck.repair=yes net.ifnames=0 elevator=noop disablehpd=${hpd} max_freq=${max_freq} maxcpus=${maxcpus} monitor_onoff=${monitor_onoff} disableuhs=${disableuhs} mmc_removable=${mmc_removable} usbmulticam=${usbmulticam} ${hid_quirks}"


Could you try it?
And if you have any other problem, please let me know.

For the future, I have to build-up a new logic for logo display and including it in released u-boot version,
so that you don't need to do this troublesome work.
I will do that and once I'm done, I will share the status here.

@facotl,
Thank you for your feedback.

And sorry for this inconvenience.
I will try to make a common interface soon to support various resolutions without this kind of additional build/fusing process.
