hello,

 

May be widely discussed this theme here, anyway I didn't find exactly for my case

 

I have this cheap dongle tuner, recognized by box zgemma star s with openpli 7.3:

but as dvb-t/2, and I, desperately, need a dvb-c.

It, clearly, registers one frontend only. Refering to: https://linuxtv.org/...strometa_DVB-T2, I think that is model TVR801/R820T, where is specified, also, that may be not support dvb-c. I downloaded a latest kernel source and while browsing menuconfig, found at 'device drivers' - 'multimedia support' - 'Media ancillary drivers' - 'customize dvb frontends' where driver rtl2832 is exclusively under dvb-t section.

 

Saying these, I used this tuner as dvb-c in windows with altdvb working ok, in HD too:

USB\VID_15F4&PID_0131&MI_00\6&12B1B47A&0&0000

with drivers got at manufacturer website: http://www.astrometa...egrated_en.html.

There are separated windows drivers for dvb-t and dvb-c, not both, no support for linux, briefly mentioning that drivers are integrated in kernel.

 

Is there a happy end for using this tuner as dvb-c?

thanks in advance

I attached tuner on pc debian64 with a custom kernel 5.9.1 and it was fully recognized and connected:

Then I made a openembedded environment and build image for zgemma h7. I applied the patch here: https://patchwork.ke...445.GA1344@NMT/, then changed original cxd2841.c, cxd2841.h and cxd2841_priv.h of original kernel(4.10.12) with the same of kernel 5,9,1, after eleminating some errors, I can obtain cxd2841.ko, put it in the box, but it cannot boot if tuner is attached with kernel panic:
