ADSP-218x DSP Loader Guide
Loader operations depend on loader options, which control how the
loader processes executable files, letting you select features such as loader
kernel, boot type, and output file format. These options appear on the
loader's command line or the Load page of the Project Options dialog box
in the VisualDSP++ environment.

Option setting on the Load page correspond to switches displayed
on the command line.
To generate a boot-loadable file, you can specify the loader options from
within the VisualDSP++ environment. VisualDSP++ invokes the
and builds the output file. To generate a non-bootable PROM

file, you must run the
To ensure correct operation of the loader, familiarize yourself with:
• "Boot Modes" on page 5-2
• "Determining Boot Modes" on page 5-4
• "EPROM Booting (BDMA)" on page 5-6
• "Host Booting (IDMA)" on page 5-11
• "No Booting" on page 5-13

Boot Modes

A fully debugged program can be automatically downloaded to the proces-
sor after power-up or after a software reset. The way the loader creates a
boot-loadable file depends upon how your program is booted into the
