Boot Modes
Boot Modes
Once an executable file is fully debugged, the loader utility is ready to
convert the executable file into a processor-loadable (boot-loadable) file.
The loadable file can be automatically downloaded (booted) to the processor
after power-up or after a software reset. The way the loader utility
creates a boot-loadable file depends upon how the loadable file is booted
into the processor.
The boot mode of the processor is determined by sampling one or more of
the input flag pins. Booting sequences, highly processor-specific, are
detailed in the following chapters.
Analog Devices processors support different boot mechanisms. In general,
the following schemes can be used to provide program instructions to the
processors after reset.
“No-Boot Mode”
“PROM Boot Mode”
“Host Boot Mode”
No-Boot Mode
After reset, the processor starts fetching and executing instructions from
EPROM/flash memory devices directly. This scheme does not require any
loader mechanism. It is up to the user program to initialize volatile
memories.
The splitter utility generates a file that can be burned into the PROM
memory.
