[PATCH] lib/xtrx: honouring/using the loglevel parameter

by Gwenhael Goavec-Merou

loglevel parameter is never used and let loglevel to DEBUG, with an annoying flood of message in terminal. This patch adds a call to xtrx_log_setlevel() at xtrx constructor level.

Cheap RTL2832U / FC0012 gives "No supported tuner found", but has I2C devices

by Nick Burch

Hi All I bought a cheap DVB-T stick that was supposed to be a RTL2832U with a FC0012 tuner with RTL-SDR support. As might have been expected given the price, it doesn't work. The various rtl_ tools all report "No supported tuner found", eg rtl_eeprom gives: > Found 1 device(s): > 0: Generic RTL2832U OEM > > Using device 0: Generic RTL2832U OEM > No supported tuner found > Enabled direct sampling mode, input 1 > > Current configuration: > __________________________________________ > Vendor ID: 0x0bda > Product ID: 0x2838 > Manufacturer: Realtek > Product: RTL2838UHIDIR > Serial number: 00000001 > Serial number enabled: yes > IR endpoint enabled: yes > Remote wakeup enabled: no > __________________________________________ The vendor did give me a full refund suspiciously quickly, so clearly the lack of advertised RTL-SDR compatibility is well known to them! I then took the cover off, and it does have a chip that's labelled RTL2832U, plus another similar sized one I can't read the label of. After a bit of searching, I found this old post with a patch to list all the I2C devices: https://www.mail-archive.com/osmocom-sdr@lists.osmocom.org/msg00454.html That reports: > I2C devices found: > 20 a0 a2 So there is something working there, but I'm not sure if it's enough... Is there any hope for this stick? And if so, what would my next steps be? Thanks Nick
