Re: PCTV Triplestick and Raspberry Pi B+
Patrick has suggested many things here worth trying. In addition, you can load the modules with more debugging enabled: unload the modules first modprobe si2168 dyndbg==pmf modprobe si2157 dyndbg==pmf modprobe em28xx debug=1 If you are willing to try, TechnoTrend CT2-4400 has the same si2168 and si2157 chips, but instead of the EM28xx it uses another USB bridge. There are at least a few reports of people having a working CT2-4400 with RPi2 here: http://openelec.tv/forum/71-pvr-live-tv/72071-experimental-support-for-tt-ct2-4400-dvb-t2-c?start=30 Furthermore, kernel 3.16 was the first one to support the TripleStick and the Si2168/si2157 chips. The drivers for those SiLabs devices have improved quite significantly since that. Also, be extra careful with the firmwares - I remember there was something different in the way kernel 3.16 handled the Si2168 firmware compared to anything newer than that. If you could try to upgrade the intel devices to 3.17 at least (or with the latest media-build), download the firmware from http://palosaari.fi/linux/v4l-dvb/firmware/Si2168/Si2168-B40/4.0.11/ and place it in /lib/firmware and then redo your test, it would be helpful.

Yes, it was an assumption - not a right one as it turned out. I didn't find any obvious 32/64-problem in the si*-drivers you are using. I'm too afraid to look into the em*-drivers and I doubt that there is any obvious 32/64-bit-problem. If I were you, I would try to compare the usb-traffic (using usbmon with wireshark) between a working tune on one frequency with one standard on each of the 3 scenarios (maybe starting with the intel 32 and 64 platform). For example on each platform: 1) start wireshark-capture on the right USB-port, 2) plug the device, 3) tune (tzap) a valid DVB-T frequency 4) stop capturing Then compare the traffic log. Most outgoing data should be identical. Incoming data (except monitoring values and TS) should be equal as well. If you see differences in data-buffer-sizes or during the firmware-download-phase or anywhere else, we can try to find the code which corresponds and place debug messages. You are lucky, your drivers are using embedded firmwares which simplifies the communication between the driver and the device. regards, -- Patrick. -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

Yes, I also tested that. The firmware is identical and the LNA as well. It do work 100% of the times I scan on the Intel platform. OK - strange, is the issue reproducable with the current version of w_scan? -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

Maybe that could be the difference - unlike the 290 the 292e won't tune with apps that are not dvb-t2 "aware" eg. dvbv5-zap will work but not tzap. The current version of w_scan and eg. tvheadend will work, but older versions may not. -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
