Hi @inahike

Thank you for your report.

This is good enough to proceed with things; as it shows that the module and firmware are in place.

I will update this post when the IOCTL fix is ready.

Thanks for your feedback

Hi,

Please see this post:

[TESTING] Support for DVB adapters

Hi, For some time we’ve been struggling to get DVB support to work properly on the Vero 4K. Fortunately, we’ve now made some progress. Further, there’s no longer any need to patch TVHeadend or any userspace application; as the ioctl compatibility support is wholely in kernel. This means you can use any tools like w_scan etc without having to recompile them for the Vero 4K. It seems that the media_build backports from 4.4 wasn’t reliable. Instead, we’ve chosen to get most adapters working, ra…

To early overjoyed one dvb adapter working but most important adapter (dvbt2 HD)now osmc dont see anymore ! On vero 1 still working this adapter

[grahamh]

Try copying the fw files which work on the vero1 across to the vero4k. In lib/firmware IIRC. There are a few versions of them. Going to try my 0572:c688 later.

All working fine with my August T210, which is basically a badged Mygica T230. These are the firmware versions:

[sam_nazarko]

Can you show me the logs from Vero 1?
Also make sure you select the right apdater in TVH. Some devices have multiple adapters, of which only some support DVB-T2.

Cheers

full log

[sam_nazarko]

The formatting of the Vero 4K dmesg is very hard to read.

[grahamh]

The driver doesn’t seem to be loading at all. Can you post full logs grab-logs -A please?

[inahike]

@grahamh
