multiproto and tt3200: don't get a lock

Hi all,

I am already a few weeks experimenting to get my tt3200 with the multiproto driver to work. Still no lock on a channel. May be someone can give me good suggestion?

Henk Schaap

Here is some data:

Distribution: Suse 10.3
TT-budget S2-3200
Multiproto driver from Manu
Instruction to install the driver: from
http://www.vdr-wiki.de/wiki/index.php/OpenSUSE_VDR_DVB-S2_-_Teil2:_DVB_Treiber
szap patch from Manu

DMESG looks nice to me, only the failing probe of rtc_cmos is suspicious!

And zapping to a channel with szap gives the following result:

try please witch patched szap2

http://abraham.manu.googlepages.com/szap.c

==========================================
Make sure you have the updated headers (frontend.h, version.h in your include path)
(You need the same headers from the multiproto tree)

wget http://abraham.manu.googlepages.com/szap.c
copy lnb.c and lnb.h from dvb-apps to the same folder where you downloaded szap.c
cc -c lnb.c
cc -c szap.c
cc -o szap szap.o lnb.o
That's it

Igor,

Thank you for pointing me in the good direction. I checked the szap.c from Manu again and noticed that I had to change the declarations of the include files frontend.h and lnb.h (I copied them from the multiproto-tree to the same directory as szap.c). It seems to be that _#include <frontend.h>_ has a different meaning than _#include "frontend.h"_ (I am not familiair with C).

This means for szap.c:
#include "frontend.h"
#include "version.h"
#include "lnb.h"
And for lnb.c:
#include "lnb.h"

This is it. After compiling szap works good and I get a lock for any channel!

Thanks!

Henk
