Signal: FE_READ_* failed

Post by minius3r » Sun Feb 10, 2019 11:47 am

Hi!

I get the following erros while playing a stream for the first time:

Code: Select all

[10/02 12:21:10.620 signal]: ad 0 ioctl fd 8, FE_READ_BER failed, error 524 (Unknown error 524)
[10/02 12:21:10.620 signal]: ad 0 ioctl fd 8 FE_READ_SIGNAL_STRENGTH failed, error 524 (Unknown error 524)
[10/02 12:21:10.620 signal]: ad 0 ioctl fd 8 FE_READ_SNR failed, error 524 (Unknown error 524)
When I stop an restart the stream, the error is gone:

Code: Select all

Yes I think there were similar reports and seems to be related to the answer from the driver. I did not see anything wrong in the log. If it bothers you, try using a different version.

Hi,

as you use media_build drivers you may have to make sure that the dvb header includes get used from media_build and not from your kernel.

Hi,

thank you for your answers.

I reinstalled the linux-*-4.15.0-45-generic packages to go back to the "standard" drivers and recompiled minisatip with ddci support.

Now minisatip does not detect the CI interface. It's working fine with tvheadend.

Code: Select all

find /dev/dvb
/dev/dvb
/dev/dvb/adapter3
/dev/dvb/adapter3/ci0
/dev/dvb/adapter3/ca0
/dev/dvb/adapter2
/dev/dvb/adapter2/ci0
/dev/dvb/adapter2/ca0
/dev/dvb/adapter1
/dev/dvb/adapter1/frontend0
/dev/dvb/adapter1/net0
/dev/dvb/adapter1/dvr0
/dev/dvb/adapter1/demux0
/dev/dvb/adapter0
/dev/dvb/adapter0/frontend0
/dev/dvb/adapter0/net0
/dev/dvb/adapter0/dvr0
/dev/dvb/adapter0/demux0

Sorry,

removing /lib/modules/4.15.0-45-generic and reinstalling the packages again fixed the problem with the CI interface.

What is the recommended ddbrdige driver, git://linuxtv.org/media_build.git or https://github.com/DigitalDevices/dddvb?

Thanks!

Hi,

for me the kernel ddbridge drivers have still some issues with my DVB-S2 6.5 where I somteimes get not lock. There are also missing IOCTL's for the DD flash tools. So my suggestion is: If you do not need other DVB hardware as DD cards then go with the dddvb.
When you install a dddvb dkms then you do not need to take care if a kernel upgrade comes up it will build automatically for your new kernel.

Hi!

I compiled and installed dddvb-0.9.36. As you noted I also included the headers in the minisatip build:

Code: Select all

CFLAGS?=-Wall -Wno-switch -ggdb -fPIC -I/path/to/dddvb-0.9.36/include $(EXTRA_CFLAGS)
Unfortunately, minisatip only detects adapter0 and 1 but not the CI, while tvheadend does.

Anything else I could do worng?

Hi,
as you do have a single DD CI you have to compile minisatip with "make DDCI=1".

Hi 9000h,

that's what I did.

With the "stock" kernel drivers, the CI is recognized.

Hi,

can you upload a short log minisatip with start option -ladapter,ca and a "ls -R /dev/dvb".
