LE10 & TBS 5520SE on RPi4 // updated drivers [SOLVED]

unkrocks · August 25, 2021 at 11:38 PM

Thanks smp . I followed your instructions to the letter

tbs5520SE not recognised, beyond lsusb seeing it (below)

(pastekodi and other debug info below)

I checked the build logs and it looks like your excellent patch is being applied (54.log excerpt below)

Having followed nvdias above, I wonder if...

- firmware is correctly installed for tbs5520se ?? I haven't tweaked any firmware

Any help anyone can give is much appreciated

For interest - I am actually trying to debug my friends tbs5520SE a few hundred miles away in Scotland so he is not without TV - smile

edit projects/RPi/devices/RPi4/linux/linux.arm.conf, add the line CONFIG_DVB_USB_TBS5520SE=m.

Make the same change to linux.aarch64.conf file.

nvdias · August 26, 2021 at 10:40 AM

yes. changes now go into linux-aarch64.conf.

I'veupdated the compiled drivers and upload them.

Available here:

unkrocks · August 27, 2021 at 1:54 AM

Huge thanks to smp and nvdias for helping

I tweaked the linux.aarch64.conf file as smp suggested, re-compiled and now my scottish friend is up and running with a current matrix LE using tbs5520SE

Next steps...

- I'll go back and explore nvdias kernel overlay so I understand it
- if I get time I'll post up a Noobs guide to compiling LE with what I have learnt (if that is helpful?)

nvdias · February 11, 2022 at 8:09 PM

[FALSE PROBLEM ---- IGNORE THIS POST]

well ... drivers are no working anymore.

I've updated the patch file as the offsets changed (see attach) and it worked for builds compiled with version up to 2nd February 2022.

After that, tvheadend cannot lock signal.

dmesg reports errors:

Code

si2183 22-0067: err restarting dsp
si2183 22-0067: err set agc mode
si2183 22-0067: err set dvb-c mode
si2183 22-0067: err restarting dsp

Any help will be greatly appreciated.

I assume you are using rpi kernel 5.15.18.

Looking at the git commit history it looks like this commit was merged to kernel 5.15.17, so you may want to revert it for testing.

Correct. 5.15.18 it is.

I will then try swapping the initialization bits for si2157 , recompile and report back.

nvdias · February 12, 2022 at 1:27 PM

well ...

reverted the patch .. works.

placed the patch back and it also works !!!

if ..... "make clean" and recompile everything

So, after the changes for 5.15.17 / 5.15.18 I should have rebuild everything.

my bad.

sorry.

everything is working ok.

smp , thank you for your suggestion it sent me in the correct path.

TBS 5520SE drivers for LIBREELEC 10 on Raspberry pi 4:
(updated for kernel 5.10.52)
Just download the zip file from this mega shared folder:
https://mega.nz/folder/cbwCARoR#jPgzah63psSCOtrwbt9gnQ
Unzip it to your Rpi4, make the install script executable and execute-it:
chmod a+x install-tbs.sh
./install-tbs.sh

NOTES:
How it was done ?
Compiled tbs 5520se drivers for libreelec 10.
to be mapped as kernel-overlays.
a) firmwares (*.fw) files in --> /storage/firmwares
These firmware files will be loaded as new firmwares.
b) driver (*.ko) files in --> /storage/.cache/http://driver.dvb.tbs/lib/modules/5.…/driver.dvb.tbs
These are the new drivers to be mapped over kernel-overlays directory.
c) 99-driver.dvb.tbs.conf --> /storage/.cache/kernel-overlays
Will instruct libreelec to map these *.ko files at boot time.

- To stop loading the drivers, delete the file:
/storage/.cache/kernel-overlays/99-driver.dvb.tbs.conf

Can you update this for the current kernel please?

nvdias · June 30, 2022 at 6:06 PM

I'm now with LE11 form quite some time.

not using LE10 anymore.

I have the drivers compiled for LE11 kernel 5.15.45. It should be compatible with LE10 if you are in the same kernel version:

(confirm with "uname -a")

Available in the same folder:

LibreELEC-Generic.x86_64-10.0.2 (Linux Kernel 5.10.76), could you help to compile drivers for this? Thank you!

Hi. Sorry. But at the moment I can only maintain compilations for RPi4.

If you want to yourself for x86_64, just create the compilation environment and toolchain. following official instructions:

https://wiki.libreelec.tv/development-1/build-basics

Once you are able to create a LE image, came back here. I will help inject the patches for x86_64.

molive · September 26, 2022 at 6:47 PM

Hi,

Trying to replicate for RPi2. Its building ok, but TBS5520 is not installing. Shows on lsusb, but not on lsmod.

Any help appreciated.

Thanks in advance.

Have you adjusted the tbs5520se patches to be applied into rpi2 project / device ?

Hi,

Placed the patch found in post #23 of this thread (dropbox file is offline) in /projects/RPi/patches/linux and /projects/RPi/devices/RPi2/patches/linux.

Have to edit the patch file for RPi2?

Thanks.

nvdias · September 27, 2022 at 8:47 PM

The patch was updated for One of the latest kernel versions.

Please try one of the last links some posts above.

If not, I will re-upload the patch later.

Can´'t find any working link for the patch except the one in post #23.

Would really appreciate if you could re-upload it.

Thanks in advance.

The link in post #28 it is working fine:
https://mega.nz/folder/cbwCARoR#jPgzah63psSCOtrwbt9gnQ

It points to a folder with compiled drivers for Rpi4.

I've added the patches files into a zip file and uploaded it into that same folder.

le-tbs5520se-patches-220927.zip

The patches are generic for the drivers compilation.

You need to edit the module activation patch to you project (RPi2 ?) as it expects the RPi4 project.

Good luck.

And post your results here.
