TBS 6285 not working #168

Closed bpbastos closed 5 years ago

bpbastos commented 5 years ago

I've closed the other issue to elaborate a little more about the problem.

Just to explain my setup, I'm running tvheadend inside a LXC container and passing the dvb cards to it, the driver and firmware are installed on the host machine - Proxmox (Debian), this setup worked as expected using ljalves drivers for a long time. Along this time, I've tried to use the new open source drivers but I've never been able to put it to work, no mattering the kernel or distro, so I always ended up using ljalves drivers.

I was forced to upgrade my distro and therefore the kernel was also upgraded to 5.x. So I have no options besides giving the tbs's open source drives a new try.

I was able to build the latest driver and the modules are loaded correctly acording to dmesg:

HI Because your symbol rate less than 6000000, you can see the si2168.c(drivers/media/dvb-frontends/). the function of "si2168_set_frontend", when the symbol rate less than 6M, it will be set to DVBC_ANNEX_B mode,(line333~337) if (c->symbol_rate < 6000000) { delivery_system = 0x10; c->delivery_system = SYS_DVBC_ANNEX_B; c->bandwidth_hz = 6000000; } so, you just disable them. now it was fixed . you just need update the drivers, then re-make and install. thanks

Hi @Davin622 both TBS 6285 and 6205 are working beautifully now. Thank you!
