All file types that used by the bootloader software are listed below:
- The Binary File :It has “.bin” extension and it is the TV application. Its size is 1920 Kb.
- 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.
- The Test Script File :It has “.txt” extension and it is the test script that is parsed and executed by the bootloader. It doesn’t have to be any times of 64 Kb.
- 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.
USAGE OF THE BOOTLOADER
- The starting to pass through : The chassis is only powered up.
- 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.
Bit per second: 115200
Data bits: 8
Parity: None
Stop bits: 1
Flow control: NoneIn this case the bootloader sofware puts “C” character to uart. After repeating “C” characters are seen in the hyper terminal user can send any file to chassis by selecting Transfer => Send File menu item and choosing “1K Xmodem” from protocol section.
The Sample Output Before Sending The File
EEProm update. To Update eeprom content via uart scart,dsub9 or i2c with Mstar tool can used.

In the Software updating Procedure section, when the first “C” character is seen, the filename selection process must be finished before 10 seconds. If the process cannot be finished, the file sending operation will be cancelled.
The following figure shows this situation.
Capture of Receiving Data Failing
- When sending the file the following window must be seen.
- After the sending process the following HyperTerminal window must be seen.
Capture of End of The Sending Process.
- For sending second program file, the Software Updating Procedure must be repeated from the step X. Select the “Filename xxxx_slot2.img” using “Browse”.
- After sending the second program file, the Software Updating Procedure will be successful.

17MB37 - DIGITAL SOFTWARE UPDATE FROM USB
- Copy the bin file, including higher version than the software loaded in flash, into the USB flash memory root directory. This file should be named up.bin.
- Insert the USB disk.
- Digital module performs version and CRC check. If version and CRC check is successful, then a message prompt appears to notify user about new version. If the user confirms loading of new version, upgrade.bin file is written into flash unused slot.
- Digital module disables the previous software in the flash and then a system reset is performed.
- After the reset, digital module starts with new software.
REVERT OPERATION
With revert operation, it is possible to downgrade the software.Revert operation is very similar to upgrade process. In the revert operation, file name should be f_up.bin. Also user confirmation is not asked.
- Copy the bin file into the USB flash memory root directory. This file should be named force_upgrade.bin.
- Insert the USB disk.
- A lower version than the software in flash can be loaded with revert operation. Digital module performs only CRC check. If CRC check is successful, then force_upgrade.bin file is written into flash unused slot.
- Digital module disables the previous software in the flash.
- A message prompt is displayed to notify user about end of revert process.
- Power off/on is required to start digital module with the new software.
