According to the protocol tftp the device loads ("mag200/ STB-bootlogo.bmp.gz
") from the server specified in the next-server located on the route filename, performs
check, displays the logo on the screen and saves the logo.
Besides, it is possible to set the coordinates of the left upper corner of the logo.
These are dhcp options: TeleTec.logo_x – x axial coordinate, TeleTec.logo_y – y axial
coordinate. If these options are not specified or if they are reset, the picture shall be
automatically centered.
The options dhcp TeleTec. bg_color and TeleTec.fg_color allow specifying
correspondingly the colour of the background and the colour of the type in the format
“XRGB” for displaying information messages in the process of loading.
If the process was successfully completed, the variables of the bootloader
“logo_x”, “logo_y”, “bg_color”, “fg_color” are set to the corresponding values and the
variable “showlogo” is set to “yes”.
This process also sets the signed and prepared operator key. If the dhcp answer
has the option TeleTec.oppubfile set, the attempt to read from the server the indicated
file according to the protocol tftp is performed, and in case of success the bootloader
variable “oppubKEY” is assigned with the contents of the loaded file.
Hereinafter it shall be used as the operator key.
Steps after switching on the device
When the system is started, the bootloader analyses the loading mode set. If the mode
“NAND” is specified, the basic program is started from nand-flash, if “DHCP” is
specified, the start is performed using dhcp protocol.
