A flash loader is an agent that is downloaded to the target. It fetches your application from the debugger and programs it into flash memory. The flash loader uses the file I/O mechanism to read the application program from the host. You can select one or several flash loaders, where each flash loader loads a selected part of your application. This means that you can use different flash loaders for loading different parts of your application.

Flash loaders for various microcontrollers are provided with IAR Embedded Workbench for RISC-V. In addition to these, more flash loaders are provided by chip manufacturers and third-party vendors. The flash loader API, documentation, and several implementation examples are available to make it possible for you to implement your own flash loader.
