Re: DVBSky T980C CI issues (kernel 4.0.x)
i think i need to revive this very old thread. i ran into some problems with my new dvb box after the old one gave up permanently (probably due to worn out flash) and then learned a few things. apparently i need to use PLP=1 for the dvb-t2 channels to get a lock. if i use my dvb box and uses plp=0 as is the default it never locks on to the t2 frequencies and never finds any of the dvb-t2 channels (= all the hd channels) so as was discussed earlier i think my issue with the new version of ct2-4650 is related to plp. when this thread was going last year i ran into issues i could not solve and then gave up since it wasn't too important to have the ct2-4650 working. but maybe it is time to give this another try. also last year i had issues loading the media build modules due to an extra kernel module that was built that i just had to delete (didn't know it back then) so, two main questions: how is plp supposed to work? is the drivers supposed to auto detect this? if so, how do i convince the drivers to use plp=1 when i use for example w_scan ? and secondly, if drivers is supposed to auto detect plp, it clearly doesn't happen for me. since this works on windows, is it possible that the windows driver is using a newer firmware for the si6168-b40 than 4.0.25? (latest one i found on: http://palosaari.fi/linux/v4l-dvb/firmware/Si2168/Si2168-B40/) any advice on how to check or capture what the windows driver uses? thanks.

Success! both t2 muxes was found and w_scan showed what looked like the complete channel list. forth test: now that it is working, reinsert CA module and retest. problem is back. same error as previous tests with CA module inserted "no data from PAT after 2 seconds" on each locked on frequency. a comment regarding the CA module. no matter what driver i have used, the dvbsky binary blob driver or linux-media driver or kernels built in driver all of them have had minor CA issues. at every boot i need to first tune to a dvb channel then unplug the CA module and reinsert it, when this is done the channel starts working. if i don't do this manually i will never get a picture. i guess this could be an application issue too since sending a CA_RESET also seems to fix it, but because of how the program i use work doing a good test is a bit hard.

Re: DVBSky T980C CI issues (kernel 4.0.x)
Hi Jurgen, Ah, that's interesting. My T980C (and based on printout from Torbjörn his as well) have Si2168-A20 chips. Some things I'd like to understand: - is there a difference if the CI slot is populated or not? - is there any difference between the different firmwares? - does it work with the DVBSky provided driver? - when you say it doesn't work, is the issue that the demodulator does not lock on the DVB-T2 muxes? Two different firmwares for A30 chip: https://github.com/OpenELEC/dvb-firmware/blob/18b12de1f57b3c70a681983638989f94590b19f1/firmware/dvb-demod-si2168-a30-01.fw?raw=true https://github.com/OpenELEC/dvb-firmware/raw/dc7cf270e328de144e75a30d970b6e147e8bcb6e/firmware/dvb-demod-si2168-a30-01.fw I think the second one is newer, but don't have the means to verify right now...

Re: DVBSky T980C CI issues (kernel 4.0.x)
i was about to ask how to easiest see what firmware i was running without rebooting when i realized i already have it in this mail thread ;) all of the firmware i'm running is the ones that came from dvbsky directly in this file: http://www.dvbsky.net/download/linux/dvbsky-firmware.tar.gz i suspect i should go thru all of the firmware files i use since if one is bad the other ones is probably also bad. i assume i also should also check: dvb-tuner-si2158-a20-01.fw what version is a good one? i have found 2 different files: the one i current usefrom dvbsky, also same as OpenELEC fw repo uses with md5sum: 8e98d25d6219e235b519a3c47dbfa856 dvb-tuner-si2158-a20-01.fw and then i found another one at http://palosaari.fi/linux/v4l-dvb/firmware/Si2158/Si2158-A20/ 0cba7ce61c1411cbe7f22c0746e24e33 dvb-tuner-si2158-a20-01.fw this file is a bit smaller. i will retest with the new firmware you suggested and see what happens.

Re: DVBSky T980C CI issues (kernel 4.0.x)
Hi Jurgen, Torbjörn, I've noticed that there is currently a small confusion about the firmware versions for the Si2168-A20 demodulator. This is used in the older versions of DVBSky T680C (TechnoTrend CT2-4650 CI) and DVBSky T980C (TechnoTrend CT2-4500 CI). The version 2.0.5 does not support PLP handling and seems to work very badly with the Linux driver - at least for me. Version 2.0.35 on the other hand seems to find all DVB-T/T2 channels for me just fine with both dvbv5-scan and w_scan (devices used for this test: TechnoTrend CT2-4650 CI and TechnoTrend CT2-4500 CI new version). Versions used: dvbv5-scan version 1.7.0 w_scan version 20150111 (compiled for DVB API 5.10) So if you are running these Si2168-A20 based devices, make sure you've got the firmware 2.0.35 that can be downloaded for example here: http://palosaari.fi/linux/v4l-dvb/firmware/Si2168/Si2168-A20/32e06713b33915f674bfb2c209beaea5/ Cheers, -olli On 20 February 2016 at 19:20, Jurgen Kramer wrote: > Hi, > > On Sat, 2016-02-20 at 16:57 +0100, Torbjorn Jansson wrote: >> i have tested your patch with my dvbsky dvb-t2 card. >> testing was done by compiling a custom kernel with your patch >> included. >> test was done against fedora 22 4.3.4-200 kernel >> >> with the patch included the CI slot is found. >> so there is some progress for sure >> - >> [ 10.189408] cx25840 11-0044: loaded v4l-cx23885-avcore-01.fw >> firmware >> (16382 bytes) >> [ 10.206683] cx23885_dvb_register() allocating 1 frontend(s) >> [ 10.207968] cx23885[0]: cx23885 based dvb card >> [ 10.224306] i2c i2c-10: Added multiplexed i2c bus 12 >> [ 10.225633] si2168 10-0064: Silicon Labs Si2168 successfully >> attached >> [ 10.243310] si2157 12-0060: Silicon Labs Si2147/2148/2157/2158 >> successfully attached >> [ 10.244560] DVB: registering new adapter (cx23885[0]) >> [ 10.245807] cx23885 :07:00.0: DVB: registering adapter 0 >> frontend >> 0 (Silicon Labs Si2168)... >> [ 10.417402] sp2 9-0040: CIMaX SP2 successfully attached >> [ 10.447120] DVBSky T980C MAC address: 00:17:42:54:09:85 >> [ 10.448844] cx23885_dev_checkrevision() Hardware revision = 0xa5 >> [ 10.450550] cx23885[0]/0: found at :07:00.0, rev: 4, irq: 19, >> latency: 0, mmio: 0xf6e0 >> >> later when tuning: >> >> [ 67.728109] si2168 10-0064: found a 'Silicon Labs Si2168-A20' >> [ 67.802203] si2168 10-0064: downloading firmware from file >> 'dvb-demod-si2168-a20-01.fw' >> [ 68.968336] si2168 10-0064: firmware version: 2.0.5 >> [ 68.977071] si2157 12-0060: found a 'Silicon Labs Si2158-A20' >> [ 69.961057] si2157 12-0060: downloading firmware from file >> 'dvb-tuner-si2158-a20-01.fw' >> [ 70.969094] si2157 12-0060: firmware version: 2.1.9 >> >> >> but using dvbv5-scan to scan it doesn't find any channel. >> all i get is this: >> >> Scanning frequency #1 77000 >> (0x00) Signal= -114.00dBm >> Scanning frequency #2 75400 >> (0x00) Signal= -27.00dBm C/N= 32.50dB >> Scanning frequency #3 54600 >> (0x00) Signal= -25.00dBm C/N= 33.75dB >> Scanning frequency #4 65000 >> (0x00) Signal= -18.00dBm C/N= 36.00dB >> Scanning frequency #5 52200 >> (0x00) Signal= -28.00dBm C/N= 33.00dB >> >> >> so something else is broken too. >> > I have been using the patches for a few days.

You could patch the Makefile with a patch from Oliver Endriss (attached). This way all modules get installed in /lib/modules/`uname -r`/updates/media If your kernel needs it, you can compress them afterwards. -- 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 --- v4l/Makefile 2013-11-27 16:15:21.528260850 +0100 +++ v4l/Makefile 2013-11-27 16:24:37.171815316 +0100 @@ -154,6 +154,7 @@ PWD := $(shell pwd) DEST := /lib/modules/$(KERNELRELEASE)/v4l2 KDIR26 := /lib/modules/$(KERNELRELEASE)/kernel/drivers/media +INSTDIR := $(DESTDIR)/lib/modules/$(KERNELRELEASE)/updates/media # # Compiler fixup rules @@ -202,9 +203,18 @@ # # installation invocation rules -modules_install install:: media-install firmware_install - -remove rminstall:: media-rminstall +modules_install install:: rminstall firmware_install + install -d -v $(INSTDIR) + @for i in *.ko; do\ + echo "install $$i -> $(INSTDIR)/"; \ + install -p -m 644 $$i $(INSTDIR); \ + done; + strip --strip-debug $(INSTDIR)/*.ko + /sbin/depmod -a $(KERNELRELEASE) $(if $(DESTDIR),-b $(DESTDIR)) + +remove rminstall:: + @rm -Rfv $(INSTDIR) + /sbin/depmod -a $(KERNELRELEASE) $(if $(DESTDIR),-b $(DESTDIR)) firmware_install:: make -C firmware install

I thought lets try a current 4.0 kernel to see if I no longer need to be
running a custom kernel. Everything works just fine except the CAM
module. I am seeing these:
[ 456.574969] dvb_ca adapter 0: Invalid PC card inserted :(
[ 456.626943] dvb_ca adapter 1: Invalid PC card inserted :(
[ 456.666932] dvb_ca adapter 2: Invalid PC card inserted :(
The normal 'CAM detected and initialised' messages to do show up with
4.0.8
I am not sure what changed in the recent kernels, what is needed to
debug this?

Retest. I've isolated one T980C on another PC with kernel 4.1.5, still the same
'Invalid PC card inserted :(' message.
Even after installed today's media_build from git no improvement.
Any hints where to start looking would be appreciated!
cimax2.c|h do not seem to have changed. There are changes to
dvb_ca_en50221.c

did you get it to work?
i got a dvbsky T980C too for dvb-t2 reception and so far the only
drivers that have worked at all is the ones from dvbsky directly.
i was very happy when i noticed that recent kernels have support for it
built in but unfortunately only the modules and firmware loads but then
nothing actually works.
i use mythtv and it complains a lot about the signal, running femon also
produces lots of errors.
so i had to switch back to kernel 4.0.4 with mediabuild from dvbsky.
if there were any other dvb-t2 card with ci support that had better
drivers i would change right away.
one problem i have with the mediabuilt from dvbsky is that at boot the
cam never works and i have to first tune a channel, then remove and
reinstert the cam to get it to work.
without that nothing works.
and finally a problem i ran into when i tried mediabuilt from linuxtv.org.
fedora uses kernel modules with .ko.xz extension so when you install the
mediabuilt modulels you get one modulename.ko and one modulename.ko.xz
before a make install from mediabuild overwrote the needed modules.
