samyGo use on LN52A850 (T-SPHAUSC v.1004)

[tskitishvili]

Hi,

I have tested SamyGO extension pack on my device and here is the list of suggestions to consider for future releases of the software pack.

1. There is no 'cut' utility implemented in busybox of <subject> device. As a result rcSGO script (any many others) of SamyGO Extension pack fails. Please consider replacing it with something working or add it into release notes on wiki page. Here is the list of command line tools available in the firmware:

2. Although executables included with extension pack seem working, running insmod on .ko modules produce errors. Example:
insmod: cannot insert `cifs.ko': Invalid module format (-1): Exec format error

The <subject> device linux and busybox seem compatible with the system listed on the SamyGO Home page:

The reason why modules do not load is that they wre compiled for version 2.6.18_SELP-ARM while the <subject> version is 2.6.18_SELP-ARM_V403_V6K

After I replaced string "vermagic: 2.6.18_SELP-ARM preempt mod_unload ARMv6 gcc-4.2" with "
vermagic: 2.6.18_SELP-ARM_V403_V6K preempt mod_unload ARMv6 gcc-4.2" inside cifs.ko I was able to load the cifs.ko module but 'mount' produces segmentation fault while using cifs. I guess since new string is longer I might have erased some import variables after that string. So it is better if someone who has working toolchain makes another set of all modules with versions string: 2.6.18_SELP-ARM_V403_V6K. For that you need to modify config variable "CONFIG_LOCALVERSION".

3. Please also consider adding these lines into rcSGO because games had to be placed in SEC_GAME folder on <subject> device:
..
elif [ -x /dtv/usb/sda1/SEC_GAME/SamyGO/etc/rc.sysinit ] ; then
S_SCRIPT="cd /dtv/usb/sda1/SEC_GAME/SamyGO ; ./etc/rc.sysinit 2>&1 &"
..

4. Please consider adding alternative SamyGO.dat file compatible with <subject> device.

5. Please also consider that there is no reference to shared library from the above .dat file. That's because <subject> device is looking for .dat and .so by name. The .dat file name should match folder name. The .so file name should have 'lib' prefix followed by name matching folder name. So .so file name should be libSamyGO.so

6. Please include into wiki description that SamyGO extension files have to be placed into SEC_GAME\SamyGO folder on USB device.

Thank you for great product.

5. Please also consider that there is no reference to shared library from the above .dat file. That's because <subject> device is looking for .dat and .so by name. The .dat file name should match folder name. The .so file name should have 'lib' prefix followed by name matching folder name. So .so file name should be libSamyGO.so

6. Please include into wiki description that SamyGO extension files have to be placed into SEC_GAME\SamyGO folder on USB device.

Thank you for great product.

good job,

I was wondering why it was not needed for me, but turns out that is needed for older series tv.
I have question for you, do you have file libGPlayerPorting.so in /mtd_exe/GAME_LIB ? and libYahooSDLHWAcceleration.so in /mtd_exe/YWidget_LIB ?

[tskitishvili]

libGPlayerPorting.so exists, however it is in slightly different place.
libYahooSDLHWAcceleration.so is missing. Actually my TV model does have just three simple widgets: weather, stocks, news.

It took me a while to get back to this but today I confirmed your findings regarding LNxxAxxx extension layout on my LN46A750. I was also able to confirm the cut problem you indicated as item #1 in this post. Have you found a workaround?

...

If you have any additional information about getting the extensions to work I would really love to hear it.

Thanks!

the init scripts are rewritten, and no more use cut. but it will be released if the starter lib is fixed to work and UE & LN devices and the build of working kernel modules is fixed.

so pls test applications/scripts/modules you find in software forum (with testing or tester needed...) and report fail/success or what you don't like or what you like to have in extensions.

Thanks for informations.
I don't know "2.6.18_SELP-ARM_V403_V6K" issue and the "no cut" issues.
I think NFS work right?

Telnet enabling require manual Bussybox injection or only Firmware patcher?
How do you make telnet enabled? (I forgot how could we that )

[erdem_ua]

What about "Telnetd Application"
I think it's not required such modifications and could enable telnet automatically. Right? Could you please test this?

Compiling kernel is not big problem. I think Aquadran could prepare new cifs.ko for your TV.
You can use some NFS server utility to test your TV's NFS connection. I think you can view your movies with it.
