17MB38 Analog Part Software Update With Bootloader Procedure.
- The File Types Used By The Bootloader. 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 don’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. 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.
USAGE OF BOOT-LOADER
- 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.
