How to jump to c_int00

will Resnick

Hi, I am creating a secondary bootloader for the 6748. The first loader reads the application out of memory and once loaded jumps to _c_int00. I have been able to correctly decode the AISGEN file but I don't know how to jump to _c_int00 to start the application. Thanks, Will

Will Resnick,

Booting:
The control passes from the ROM bootloader to the StarterWare bootloader as per the following steps.

Configures the system
Loads the application
The bootloader jumps to the application entrypoint

If external memory used in "Memory Sections"(Linker file),

Verify the DDR configuration settings used in AISgen and check with the GEL file.
The bootloader must configure the controller settings before the code is copied.
