SamyGo virtual drive MOD
Posted: Mon Sep 24, 2012 2:26 pm
I do not take any responsibility if TV bricks, hack is available "as is".
Tested on:
- UE40D6750
- UE32C6000
Now available for D-series and C-series TVs
FOR ARM PROCESSORS ONLY!
It took me months to figure out that you may create more than one SamyGO virtual drive. However every one of them has the same name and handling them wasn't "user friendly". So, I decided to change it and I hacked a little bit g_file_storage driver.
How to install hack (adjust paths to your environment):
- Download and unpack attached file
- backup /mtd_rwcommon/widgets/user/SamyGO/SamyGO/lib/modules/2.6.30.9/kernel/drivers/usb/gadget/g_file_storage.ko
- overwrite g_file_storage.ko with unpacked version
- go into /mtd_rwcommon/widgets/user/SamyGO/SamyGO/etc/init.d/
- find 02_04_vusb.init and rename it to 02_04_vusb.init.dis
- Edit 02_04_vusb.init from unpacked file and set your drives (separated by semicolon), eg
DRIVES="Movies;Laptop;Phone;QNAP"
You may create max 8 drives, and drive name may contain max 16 characters (driver restrictions)
- copy 02_04_vusb.init to your TV to /mtd_rwcommon/widgets/user/SamyGO/SamyGO/etc/init.d/
DONE! Patch has been applied. Reboot your TV. You should see 4 SamyGo virtual drives (if you haven't change 02_04_vusb.init).
What next?
Check your /dtv/SGO.env file. You should see MOUNTH_PATH* variables:
MOUNT_PATH1="/dtv/usb/sda"
MOUNT_PATH2="/dtv/usb/sdb"
MOUNT_PATH3="/dtv/usb/sdc"
MOUNT_PATH4="/dtv/usb/sdd"
This are root folders of your virtual drives. You may mount there whatever you want. In my case I have mounted movies from my PC, few folders from laptop (few shared folder mounted to one virtual drive - in subfolders), phone's SD card (to watch photos directly on tv without DLNA) and my network storage (QNAP).
You may check it on photo:
All 4 USB drives are SamyGO virtual drives.
To developers:
Right now additional parameter is required during insmod of g_file_storage.ko: "model". It should contain array of models of drives separated by comma. It should contain at least one model.
Example
insmod $MOD_DIR/kernel/drivers/usb/gadget/g_file_storage.ko file="/dtv/vusb1,/dtv/vusb2,/dtv/vusb3" model="Movies,Laptop" <= third model is omited so default will be used (SamyGo Virt)
Take look on my mount file:
@SamyGo developers
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? I dont have experience with "Make" files and C compilers - I am Java developer and I've started learning C because of SamyGo MODS
