5 Using the Flash File System
The Flash File System of the C6713CPU consists of three parts:
• A target-resident boot loader which initializes the C6713CPU at startup, looks for
commands on the RS-232 interface and then either loads auto-boot FPGA(s) / application
or loads a Flash File System command executable over RS-232.
• DSP-side executables which perform the desired function
• PC-side utilities that connect to the C6713CPU, upload the DSP-side executables and
perform the desired function.
The Flash File System supports storage and boot sequence management for both, FPGA code
and DSP applications.
For correct operation of the Flash File System, it is recommended that the CTS-reset feature is
enabled in the PLD, see chapter 3.10.4 for details. This allows the Flash File System to interrupt
the currently running program and to connect to the C6713CPU. If the CTS-reset feature is
disabled, the C6713CPU must be reset manually.
A detailed description of the Flash File System is given in [24]
