Nice, but the download link for 19.5-Matrix_rc2 takes you to 20.0-Nexus_alpha2 (Stable).

Looks like the script on the server is too smart :
Please use this until it’s fixed:

Why remove the auto color detection? It sounded useful…

Portisch · 28 July 2022 17:00

Please read the news again…

nd299 · 28 July 2022 17:14

Oh “reworked”, weird i was sure it said “removed”

Just installed on an old X96 S905x, so far no issues.

ceemmc won’t work on the > Android 11 firmware found on these s905x4 boxes for now, on which the system(super) and storage (userdata) partitions are newer ext4 fs either created from underlying device-mapper or stored directly on these partitions yet not readable for the 4.9 kernel CE is currectly using.

Also, to keep the new partitoon table from being reverted back, ceemmc has to remove the partitions node from dtb so the u-boot won’t “helpfully fix” the partition table, which is also not doable for these S905X4 boxes which must read the partition node in dtb instead of the partitoon table to get the location for several partitions, so removing the node will brick the box…

You could find some other ways to install to internal for these boxes not supported by anyone especially teamCE, but I don’t recommend even trying to install to emmc on S005X4 boxes for now.

As per documentation:

After the upgrade to 19.5-Matrix_rc2 on Odroid-N2 two lines on boot screen:
[INFO] Skipped Optee TEE-Suplicant
[DEPEND] Dependency failed for Amlogic OPTEE Video Firmware Preload Service.

Is it possible to get it rid?
And what does it means?

7Ji · 1 August 2022 13:37

“Optee TEE-Suplicant” service (opentee_linuxdriver.service) is skipped since the condition is not met:

github.com

CoreELEC/CoreELEC/blob/2e0198edcb26a68274b813debdb7573dcfacfa67/projects/Amlogic-ce/packages/linux-drivers/amlogic/opentee_linuxdriver/system.d/opentee_linuxdriver.service#L10


      
          [Unit]
          # load optee_linuxdriver if SoC is minimum SC2 (0x32) architecture

          ConditionPathExists=/usr/sbin/tee-supplicant
          Before=video-firmware-preload.service
          Wants=video-firmware-preload.service
          DefaultDependencies=no
          
          
[Service]
          ExecCondition=/bin/sh -c '[ $(awk \'/^Serial/ {printf "%%d", "0x" substr($3,0,2)}\' /proc/cpuinfo) -lt $(printf "%%d" "0x32") ] && echo 1 > $(realpath /sys/module/*tee/parameters/disable_flag) && exit 1 || exit 0'
          ExecStartPre=/sbin/modprobe -q optee_armtz
          ExecStart=/usr/sbin/tee-supplicant
          ExecStop=/bin/kill -KILL $MAINPID
          ExecStopPost=/sbin/modprobe -r optee_armtz
          
          
[Install]
          WantedBy=video-firmware-preload.service
          RequiredBy=video-firmware-preload.service

And “Amlogic OPTEE Video Firmware Preload Service” (video-firmware-preload.service) failed to start since it requires opentee_linuxdriver.service:

github.com

CoreELEC/CoreELEC/blob/2e0198edcb26a68274b813debdb7573dcfacfa67/projects/Amlogic-ce/packages/sysutils/tee_preload_fw/system.d/video-firmware-preload.service#L4


      
          [Unit]
          Description=Amlogic OPTEE Video Firmware Preload Service
          After=opentee_linuxdriver.service
          Requires=opentee_linuxdriver.service
          Before=kodi.service
          
          
[Service]
          Type=oneshot
          RemainAfterExit=yes
          ExecCondition=/bin/sh -c 'systemctl is-active --quiet opentee_linuxdriver.service && exit 0 || exit 1'
          ExecStartPre=/usr/sbin/trusted-application-setup
          ExecStart=/usr/sbin/tee_preload_fw /lib/firmware/video/video_ucode.bin
          
          
[Install]

Since these two services are only used for S905X4 for now you can simply disable these services if you’re not using a S905X4 device:

systemctl disable opentee_linuxdriver.service
systemctl disable video-firmware-preload.service

Ops… it doesn’t work on my N2:

CoreELEC (official): 19.5-Matrix_rc2 (Amlogic-ng.arm)
MyN2:~ # systemctl disable optee_linuxdriver.service
Failed to disable unit: Unit file optee_linuxdriver.service does not exist.

Sorry I’ve mistyped the service names, they should be opentee_linuxdriver.service and video-firmware-preload.service, I’ve editted my original post

rabaraf · 1 August 2022 19:16

nope, it doesn’t work, I mean: commands executed without any output so probably successfully but after N2 reboot still those two lines are on TV screen.

vpeter · 1 August 2022 19:22

If you really need to hide messages then mask both services:

systemctl mask opentee_linuxdriver.service
systemctl mask video-firmware-preload.service

And looks like we could improve this two scripts to not show anything in any case.

I’m getting HDMI sync issues on my Odroid N2+ with RC2.
As soon as anything is displayed at 2160p (even the UI) my projector will lose signal and resync every ~10 seconds.

I downgraded to RC1 and the issue is gone. Any ideas?
