Hi,
I am working in redboot configuration for adder board. I configured
it successfully. Now I want to access the redboot configuration
information(mainly network configuration information) in the application
..I accessed this in the RAM mode through virtual vectors.
But in the ROM mode I am unable to access .Can any one knows how to access
the redboot configuration information in the ROM mode.
You mean you ran a ROM application from RedBoot using the go command and
the start address? It would happen if your application configuration in
your ROM program reinitializes the virtual vector table. Have a look at
the configuration options in the HAL, particularly
CYGSEM_HAL_VIRTUAL_VECTOR_INIT_WHOLE_TABLE
