17.1.5 Downloading modules
17.1.5.1
Setting the downloading a program
Once you have made sure that there is memory in your system in which to download your code, you can then proceed
to download a program to debug. The initial selection of download module is automatic with regard to an application
generator, as it is the output from the linker. However, with regard to the debug-only project generator, it is possible for
you to browse to the module that you wish to download. This is outlined in the section 17.1.2, Selecting a debugging
platform.
