[linux-dvb] Help with Skystar HD2 (Twinhan VP-1041/Azurewave AD SP400 rebadge)

[-- Attachment #1.1: Type: text/plain, Size: 3294 bytes --]

I'm trying to get a new Technisat Skystar HD2 working. It looks like  
it is a Twinhan VP-1041/Azurewave AD SP400 rebadge.

The card hardware and satellite feed has been confirmed to work ok  
under Windows using Technisat's software.

I am using the current multiproto DVB drivers, downloaded today. These  
were patched, built and installed successfully as described for the  
Azurewave AD SP400 in the linuxdvb wiki, but the card was not  
recognised on bootup even though it was allocated a DVB adaptor  
number. This appeared in dmesg:

[   57.359723] found a UNKNOWN PCI UNKNOWN device on (01:06.0),

This is the output of lspci -vvn:

This is the output of lsusb -vv:

Note that subsystem IDs 1ae4:0001 are different to those listed in the  
wiki for the Azurewave (1822:0031).

I changed #define MANTIS_VP_1041_DVB_S2	in linux/drivers/media/dvb/ 
mantis/mantis_vp1041.h from 0x0031 to 0x0001, which changed the dmesg  
output on reboot to this:

[   60.168021] DVB: registering frontend 3 (STB0899 Multistandard)...

So that change seemed to cause the card to be recognised.

Then I tried the replacement scan and szap as suggested by the  
Azurewave wiki, but the card will not tune.

So it appears to be almost working, but I'm not sure what tests to try  
or changes to make to see if it will work.

hy,

the wiki is not up2date. 

Twinhan VP-1041 support is now in the mantis tree (inkl. multiproto)

hg clone http://jusst.de/hg/mantis

but for me, the old initialization parameters works much better. with the new 
ones i get only a destructed picture (unwatchable).

[linux-dvb] Help with Skystar HD2 (Twinhan VP-1041/Azurewave AD SP400 rebadge)

[Tim Hewett]

[-- Attachment #1.1: Type: text/plain, Size: 10504 bytes --]

Gernot,

I have now tried the mantis tree. It also needed the  
MANTIS_VP_1041_DVB_S2 #define to be changed to 0x0001 for this card,  
but after doing that it was recognised:

However it still doesn't tune. e.g.:

root@kubuntu7:~/linuxtv-dvb-apps-1.1.1/util/szap# ./szap -r -p -l  
UNIVERSAL -t 0 -a 1 BBC1West
reading channels from file '/root/.szap/channels.conf'
zapping to 1 'BBC1West':
sat 0, frequency = 10818 MHz V, symbolrate 22000000, vpid = 0x0901,  
apid = 0x0904 sid = 0x0002
Querying info .. Delivery system=DVB-S
using '/dev/dvb/adapter1/frontend0' and '/dev/dvb/adapter1/demux0'
----------------------------------> Using 'STB0899 DVB-S' DVB-S

do_tune: Frequency = 1068000, Srate = 22000000
do_tune: Frequency = 1068000, Srate = 22000000


Whereas this is the result when using an ordinary Skystar 2 card  
(which works fine):

root@kubuntu7:~/linuxtv-dvb-apps-1.1.1/util/szap# ./szap -r -p -l

Those logs don't look too bad superficially, but it's still not working.

Re: [linux-dvb] Help with Skystar HD2 (Twinhan VP-1041/Azurewave AD SP400 rebadge)

[Gernot Pansy]

hy,

have you tried some other channel on a diffrent multiplex?

i have also troubles on 2 multiplexes, but i believe that's trough my bad 
signal strength (it's the same on windows).

otherwise there have to be some initialization registers configured 
differently. manu is the only guy, how knows about that and can help you.

Re: [linux-dvb] Help with Skystar HD2 (Twinhan VP-1041/Azurewave AD SP400 rebadge)

[Simeon Simeonov]

Hi Gernot,

I can confirm that I have similar experience to yours.
By the way do you know if one can control from the soft side (register or some other means)
the max current output for the card. I am having a problem when trying to tune with a rotor.
On the Linux side the current seems to be capped at 300 mA as on the XP I see it goes to
about 440 mA. I was still surprised that this card can supply less current than the 102g but
we take what we get ...

Thanks for the help,
Simeon

hy,

the wiki is not up2date. 

Twinhan VP-1041 support is now in the mantis tree (inkl. multiproto)

hg clone http://jusst.de/hg/mantis

but for me, the old initialization parameters works much better. with the new 
ones i get only a destructed picture (unwatchable).

The card has an auxiliary power supply i/p, which should be connected, 
if you are using a larger load.
With a higher load and if you draw power from the PCI bus, it could be 
bad, as there are some
limitations to the current drawn from a PCI slot. Also, you can set the 
SEC chip for a different current
limitation.

Manu

It is a 1:1 clone of the 1040/1. Will add in the id's to the mantis tree.

Applied the ID's to the mantis tree alongwith some other

Please do test the updated mantis tree.

Manu,

I tried the changes, the card is now recognised at boot time without  
needing any manual changes to the code.

However it now no longer tunes:

Sigh! missed out something while i carried forward something. I have
applied the fix to the tree just now. Please try again.

[Tim Hewett]

Manu,

Thanks, it now tunes to horizontal transponders though not vertical  
ones. I think others have been having similar symptoms with the mantis/ 
multiproto trees.

It won't tune to any DVB-S2 transponder, but that has not changed  
since previously.

Can someone replicate this behaviour: not tuning to vertical transponders ?
Do you have any switches or a rotor in the SEC chain ?

Hmm .. Are you really sure ?

I will need the stb0899 and stb6100 modules to be loaded with verbose=5
parameter, for understanding what's happening.

I have a Diseqc 1.0 switch on this card.

I just retested using Technisat's Windows software and the vertical  
transponders still don't work, same for DVB-S2 transponders. Strange,  
they worked perfectly every time previously, e.g. BBCHD on 10847/v on  
Astra 2D. But not today. For now, my system is the problem.

Definitely still no tuning to DVB-S2 transponders under Linux,  
horizontal or vertical. Horizontal ones work ok with Technisat's  
Windows software.

Tim.

Manu,

The Diseqc switch has been removed and now all polarities tune, and  
DVB-S2 works as well.

Thanks!

Re: [linux-dvb] Help with Skystar HD2 (Twinhan VP-1041/Azurewave AD SP400 rebadge)

[Tim Hewett]

I have three diseqc switches, all different models, they all behave in  
this way. The PC also has three Skystar 2 (non HD) card and they all  
have trouble with these switches. I had hoped that because the Skystar  
HD2 has its own power supply separate from the PCI bus, that might  
help, but no.

My Technomate TM1000 receiver has no problems with any of the switches.

Different subject: I want to modify dvbstream to be able to tune the  
SkyStar HD2, is there any information on the changes to the API? I  
have tried to follow the changes made to szap.c, but so far without  
any success in terms of getting dvbstream to tune.

Tim.

Can you please try this change, whether it helps in your case ?

In mantis_dvb.c

line #251

if (!lnbp21_attach(mantis->fe, &mantis->adapter, 0, 0)) {

change it to

if (!lnbp21_attach(mantis->fe, &mantis->adapter, 0x80, 0x40)) {

and see whether it helps in improving your current limited situation.
according to the specification it should yield 500 - 650mA

A word of caution, make sure that the auxilliary power connector is
connected. Current drawn will be a bit much higher in this case,
additionally Static Current Limiting is used, hence additional dissipation,
which means more current drawn which might overload the PCI bus, hence
  it would be nice to use the auxilliary power connector.

Manu

Re: [linux-dvb] Help with Skystar HD2 (Twinhan VP-1041/Azurewave AD SP400 rebadge)

[Simeon Simeonov]

Hi Manu,

Thanks for the reply
Yes, indeed I tried over the weekend and by selecting the higher limitation by ISEL register:

if (!lnbp21_attach(mantis->fe, &mantis->adapter, 0, 0x40)) {

My rotor now moves. Do you think it is better to use static current protection?

But unfortunately that is not the end of the story. The problem that I am
having now is that patched mythtv rewrites the limits in my rotor?! And the weird thing is 
it does in such a way that I had to take the motor apart to recalibrate it. It looks like there are
hard limits in the rotor (Aston 1.2) firmware which are not the software limits because trying to reset 
them either from Linux side or from Windoz did not help. So I actually had to take it apart to recalibrate
the motor inside the rotor. I do not think there is a problem with the rotor itself because I have been using it for over 2 years with my other Twinhah 102g card without any problems.
I also wrote a small command line program (using libsec) that will do only rotor commands. With that
program I can do goto n, store, reset, soft limits. All there operations work fine. Goto nn steps also
works somewhat even though it is not taking the specified number of steps precisely. I am not sure why.

Getting back to my mythtv setup - I have a committed switch behind the rotor. So the rotor command is followed by (with 15ms delay) the switch, tone burst and then tunning commands. I turned on the verbose in mantis module and looked what i2c reports. The diseqc sequence looks correct. The only thing I see is that the fifo gets filled up by the end of the sequence so we have to wait for a few cycles before sending the next byte. So now I am thinking could there be any problems if the pause between writing the diseqc bytes is a bit longer since we write byte, check if fifo is full and then write the next byte. What do you think about that? I was thinking of trying to write the whole diseqc command and then check fifo or even better first check fifo and then write the command since we have 15ms between commands anyway.
On the side - switch works 50% of the times so I should look into that too. It is a really good Spaun switch and even with 102g works flawlessly.


Thanks for the help!
Simeon

It is similar to an Auto transmission car in comparison to a manual 
transmission one.
It depends how well you can handle it. Dynamic limitation is done by 
using PWM. The
advantage of using static limiting is a slightly higher dissipation but 
you see in some
practical cases that it can provide more current or maybe that it 
behaves a bit more
better in comparison. When you have more dissipation, the device draws a 
larger
current from the bus, but that's all about it. (Normally many people 
don't like Static
limitation due to the additional dissipation and current drawn, since it 
is not advisable
to sink large currents from the PCI bus and hence an additional 
auxiliary power connector
is provided on the card. Most cards generally draw power from the PCI 
bus alone)

I turned on the verbose in mantis module and looked what i2c reports. The diseqc sequence looks correct. The only thing I see is that the fifo gets filled up by the end of the sequence so we have to wait for a few cycles before sending the next byte. So now I am thinking could there be any problems if the pause between writing the diseqc bytes is a bit longer since we write byte, check if fifo is full and then write the next byte. What do you think about that? I was thinking of trying to write the whole diseqc command and then check fifo or even better first check fifo and then write the command since we have 15ms between commands anyway.

Ok, does sending the commands as it is on the fly help for you, rather 
than storing
all of them in the FIFO and whack them out in a disciplined way ?

If it looks working better that way, will try that and ask others as 
well whether they
see similar benefits ?

Manu

Hi Manu,

Here is some more info about my diseqc problem:

The short answer is no,  I do not see any benefits of sending the whole
diseqc command.

Unfortunately I still do not have a good idea what exactly the problem is.
Here is what I tried:
1. Bypass the rotor and connect directly to the switch: in that case switch
works 100% of the times even though I am first sending a rotor switch command
and then switch command and no repeats. This I checked with both mythtv
and szap.
2. Connect the rotor and send a rotor, followed by a switch command with no repeats.
In this case rotor works fine but the switch works 1/10 times. But my rotor does not
get reprogrammed
3. Send more than 2 diseqc command - being repeat for either switch or rotor or both.
Well if the rotor does not have to move (I have 2 satellites that I can use for that)
switch works about half of the time but as soon as try to move the rotor it gets all
reprogrammed.

I really have no idea what is happening. Again I looked up the mantis i2c commands
and all diseqc ones that are sent look correct. 
Any hints are welcome.

Thanks for your help,
Simeon
