SamyGo virtual drive MOD

[pohybel]

Silly question: have you put modified g_file_starage.ko in /dtv/usb/sda1/SamyGO/lib/modules/2.6.24_SELP.4.3.x-Cortex-A8/kernel/drivers/usb/gadget/?
or maybe: /mtd_rwcommon/widgets/user/SamyGO/SamyGO/lib/modules/2.6.30.9/kernel/drivers/usb/gadget?

Your logs looks like you have loaded some g_file_storage but not mine g_file_storage

Code: Select all

/dtv/usb/sda1/SamyGO/etc/init.d # ./02_04_vusb.init start
insmod: cannot insert '/dtv/usb/sda1/SamyGO/lib/modules/2.6.24_SELP.4.3.x-Cortex-A8/kernel/drivers/usb/gadget/dummy_hcd.ko': File exists (-1): File exists
insmod: cannot insert '/dtv/usb/sda1/SamyGO/lib/modules/2.6.24_SELP.4.3.x-Cortex-A8/kernel/drivers/usb/gadget/g_file_storage.ko': Invalid module format (-1): Exec format error

even if g_file_storage and dummy_hcd haven't been loaded at this point next log lines indicated that some version of g_file_storage and dummy_hcd have been loaded

Code: Select all

dummy_hcd dummy_hcd: USB Host+Gadget Emulator, driver 02 May 2005
...
g_file_storage: Unknown parameter 'model'
...

as you see g_file_storage has been loaded and is trying to read 'model' parameter which has been added to driver by me. It's really strange because if insmod failed so why g_file_storage is trying to read 'model'? This parameter is passed to g_file_storage in the same line as insmod so if insmod failed all command should failed

Your driver is smaller than mine why? mine is 34kb yours is 21kb ( i don't know if matter)

I don't know why by I dont think it's the problem.

one qestion i have to modify the SGO.env?

No. It should be updated by 02_04_vusb.init enclosed in first post.

It is strange but in dtv root i have 5 Vusb

Code: Select all

/ # cd dtv
/dtv # ls -a

event2                messages.tdb          www
event3                mutex.tdb

but in mediaplayer i can see only the real usb device

It means that 02_04_vusb.init has been executed and create 5 drive image files but crush at insmod of g_file_storage so images haven't been mounted into virtual drives.

Please check if you put my g_file_storage.ko in proper place and also ensure that you don't have other version of this file somewhere in your tv. As far as I know Samsung is not providing g_file_storage in firmware by default.
Check also your /dtv/usb/sda1/SamyGO/samygo.log

I have downloaded sources for C600 but this is the same sources as for C6900 and toolchaine is also the same so there is no sense to build the file once more

At the end I found this wiki page http://wiki.samygo.tv/index.php5/SamyGO ... th_your_tv with note:

Code: Select all

T-VAL* -> binaries may work, kernel modules rather not (ARMv7) (defined as T-CSERIES.. in OE barnch, you have to implement the toolchain and kernel-build for your self) 

you have mentioned that your tv has T-VALDEUC firmware. g_file_storage is the kernel module so probably this is the problem. I didn't find separate toolchain for "T-*" at samsung site and I have no idea how to build it by myself. I have found only T-VALDEUC_3011_0.zip but id doesn't contain any sources or toolchain.

Sorry but I don't know what can I do more in this matter

Hi pohybel and thanks
i have put modified g_file_storage.ko in

Code: Select all

/dtv/usb/sda1/SamyGO/lib/modules/2.6.24_SELP.4.3.x-Cortex-A8/kernel/drivers/usb/gadget/

i have only your modified g_file_storage.ko on my system (i've checked)
Maybe the problem is wrong init.d script? I also try yours original vusb init script and i disabled all others init script
So why this not work? it create 4 vusb but on dtv/usb/dev i can only see sda1 that is the real storage and samygovirt that is an hidden dir that on mediaplayer is not show.
@juuso @Arris69 we need your helps here.
Are there other way to have 4 vusb created and mounted so we can use them as mountpoint?

[arris69]

check the output of dmesg after you load the module, if it has some errors then you will se here the reason. the error message on console is nonsense....

all roads lead to rome, play around with module parameter and with scripts etc...

Skip
g_file_storage: module has no symbols (stripped?))

So maybe is because the file is stripped?

you added option -g to strip? and used the strip of your cross compiler?

[pohybel]

So why this not work? it create 4 vusb but on dtv/usb/dev i can only see sda1 that is the real storage and samygovirt that is an hidden dir that on mediaplayer is not show.

As I wrote before: It means that 02_04_vusb.init has been executed and create 5 drive image files (just files - as all others) but crushed at insmod of g_file_storage so images haven't been mounted into virtual drives.

Ok. Last chance. I have recompiled it once more on fresh and clean environment. This time I didn't strip symbols so don't be surprised that file size > 300KB. Try file in attachment and use my 02_04_vusb.init script.
If this does not help then I'm giving up.

[pohybel]

you added option -g to strip?

No. Should I?

and used the strip of your cross compiler?

yes

Hi my tv is ue32c6000 but fortunately has a valdeuc fw and valencia board so now is turned into a c6900

I'm not sure which source code should I use. I took the one for c6900. I recompile g_file_storage for it. Check it and give us your feedback. If it not work, I will try source code for c6000

i've samygoextension for t-valdeuc and when i try to start your scripts i got these message from shell on telnet connection.

Aaaahhhhhh yes...That's why I could not find it. Telnet is not available on D-series

It works now, very well
Thanks a lot
Thanks

[pohybel]

Realy? Do all your virtual drives appear in TV? Cool!
I will add this file to package in first post so other C-series user can use it.

[juusso]

I've noticed that oryginal g_file_storage.ko has ~35Kb and the one compiled by me ~200Kb. Could you please write how can I make this file smaller?

Compiled from your source and attaching stripped version of module for D series.
somewhy still get some errors with c series compiler...
