2. SOFTWARE UPDATE DESCRIPTION
1.1. 17MB38 Analog Part Software Update With Bootloader Procedure
1.1 The File Types Used By The Bootloader
All file types that used by the bootloader software are listed below:
1. The Binary File : It has “.bin” extension and it is the tv application. Its size is 1920 Kb.
2. The Config Binary File : It has “.cin extension and it is the config of the tv application.
Its size may be 64 Kb or a few times 64 Kb.
3. The Test Script File : It has “.txt” extension and it is the test script that is parsed and
executed by the bootloader. It don’t have to be any times of 64 Kb.
4. The Test Binary File : It has “.tin” extension and it is used and written by the test
groups. It is run to understand the problem part of the hardware.
Alltough a file that is used by the bootloader can be had any one of these extensions, its
name has to be “VESTEL_S” and it has to be located in the root directory of the usb
device.
1.2 Usage of The Bootloader
1. The starting to pass through : The chassis is only powered up.
2. The starting to download something : When chassis is powered up the menu key has to
be pushed.Before the chassis is powered up and if any usb device is plugged to the usb
port, the programme is downloaded from usb firstly.
Any usb device is plugged to usb port , user must open hyperterminal in the pc and
connect pc to chassis via Mstar debug tool and any one of scart,dsub9 or I2c connectors.
Serial connection settings are listed below:
- Bit per second: 115200
- Data bits: 8
- Parity: None
- Stop bits: 1
- Flow control: None
In this case the bootloader sofware puts “C” character to uart. After repeating “C”
characters are seen in the hyperterminal user can send any file to chassis by selecting
Transfer -> Send File menu item and choosing “1K Xmodem” from protocol section.

Figure 1. The Sample Output Before Sending The File
2. EEProm update
To Update eeprom content via uart scart,dsub9 or i2c with Mstar tool can used.
Serial connection settings are listed below:
- Bit per second: 9600
- Data bits: 8
- Parity: None
- Stop bits: 1
- Flow control: None
Programming menu item is choosed in the service menu and switch “HDCP Key Update
Mode” from off to on.

Figure 2. The Programming Service Menu
After then you must see Xmodem menu in the hyperterminal.To download hdcp key press
k or to download eeprom content press w.
Figure 3. Xmodem Menu
