I am a beginner in libreelec and Rock 4 SE and have a problem installing a Sundtek driver.
I got LibreELEC-RK3399.arm-10.0.2-rock-pi-4 to work with Kodi and Tvheadend on a Rock 4 SE. However, the driver installation of the Sundtek SkyTV Ultimate Dual (2x DVB-S/S2/S2X) didn't seem to work. The drivers do not appear in the Tvheadend overview.
Has anyone experience with this hardware and software installation and could help me?
This issue is fixed with the latest update.
regarding the rk3399t and the: LibreELEC-RK3399.arm-10.0.2-rock-pi-4 image found here:
did your device work, by just flashing that particular image, besides the sundtek driver? (out of the box, so to speak)
I´ m asking , because i´´ m considering the rock 4SE , but one other user in here , had issues with a pi 4 release (maybe newer)
As I understand it, the 3399t soc is a bit slower than the previous 3399, yes?
kind regards
The screenshot shows the T version to be slower than earlier versions; which means it will need a dedicated device-tree file that as a minimum defines the correct CPU opp-points and voltages to be used. If the T version is just a way to recycle low-yield chip that don't clock high enough to be sold as regular non-T chips that'll be the sole difference, although the voltages needed for stable ops might be difference from the regular chips. If it's a deliberate "low power" variant there are likely other minor silicon differences that need to be accounted for. Radxa probably have RK vendor kernels with device-trees that contain that information. I'd argue it's also their responsibility to submit support for the board to the upstream kernel. You might want to have a dig around in the Armbian forum to see if there's any prior-art there as Radxa often target Armbian support for their boards.
HP did the same a while back with its 6500 chip on the Elite Desk and Pro Desk range The 6500T was definitely a scaled back version so you may well be right https://www.notebookcheck.net/6500-vs-6500T_…5.247596.0.html
Thanks for the detailed explanation
Finnaly got my rock4se , and I can confirm that the LibreELEC-RK3399.arm-10.0.2-rock-pi-4 works fine with the RK3399-T SOC
Immediately got an update for 10.0.0.4 and the only difference was a slightly increase in the cpu load from 7% on 10.0.0.2 to 9-11% on 10.0.0.4 . The temperature was 60 degress celcius w/o fan, dropped to 40 degress with heatsinks and 40mm fan
After some time, it seems the slightly increased cpu load on 10.0.0.4 settled for the same as on 10.0.0.2 , so it was nothing to worry about, it seems.
The ram load is also 7-9% which is insane compared to my Nvidia Shield, that on Android uses it´´ s max capacity of 3gb ram on load
(I´´ m aware of Kodi on android is another talk)
I did get in contact with Adxa customer service , who told me that all rock4 - 3399 images , should work on the 4se without any issues, including Libreelec. But I must admit, that I didn´´ t trust this to be the case , because of the weaker SOC
Kodi is not a heavy-CPU application unless you're software decoding lots of media, but using the non-T device-tree means you are over-clocking the board, so you need to ensure it's properly cooled via fan or case.
I understand. Although I´´ m not sure where to find the T-device-tree (if any) ?
Sorry but I´ m fairly new to Libreelec
This is the CPU opp-table: https://github.com/torvalds/linux…3399-t-opp.dtsi
It looks like support for the 4SE board has been submitted and merged upstream: https://patchwork.kernel.org/project/linux-…@collabora.com/ .. although I don't see that in torvalds/master (will become Linux 6.6) yet, bu you should be able to pick/backport those patches onto the Linux 6.5 kernel we use in LE master easily.
Thanks for the informations regarding this particular board/cpu
Very helpfull indeed
