I managed to do it with some copies & adapts. Compile is ok and the stick is mounted (see log below).
My problem is that it cannot see channels. I think it comes from the fact that bandwidth=0, but channel is ok when I check logs in debug mode.
I've tried tvheadend, but it sees nothing. w-scan idem. Kaffeine cannot see the stick.

If I could force default bandwidth to 8Mhz I think it would solve the problem. How can I do that ?

+rtl2832_set_parameters frequency = 482000000 , bandwidth = 0

Tuning parameters are OK. bandwidth=0 means 8MHz in the DVBv3 API, so that's fine with kernels older than 3.3.
The problem is that, for some reason, the driver can't get a lock on the given frequency.

Thank you !

In fact it came from the fact that the RPi doesn't give enough power. I have to use a powered usb hub.
I also have to double check if it works on both usb ports because I've just finished my test and on one port it didn't work.

Thank you again.

Hello,

Thank you for letting me post in your forum. I'm a linux newbie so please forgive me if i make mistakes.

I'm an happy owner of a Raspberry Pi, and I would like to try my DVB-T usb stick.
I've tried to compile Ambrosa's drivers but unfortunatly we don't have kernel headers package yet for the Debian RPI, so I had to compile the whole kernel (though for a first try).
I've tried this one https://github.com/t...ernel-3.0.0.git and it's the same.
My kernel is 3.1.9 so I took 3.0.0 library. Same if I try 3.2.0.

I managed to do it with some copies & adapts. Compile is ok and the stick is mounted (see log below).
My problem is that it cannot see channels. I think it comes from the fact that bandwidth=0, but channel is ok when I check logs in debug mode.

Thanks in advance and thank you for your drivers.

Kind regards
