Programming CPU Board-specific
This chapter provides information about programming DNR-X-1G CPU Core
modules:
• Memory Map Overview (Section 6.2)
• Startup Sequence (Section 6.3)
• Setting and Reading CPU Core Parameters via Serial Port (Section 6.4)
NOTE: This chapter primarily provides descriptions of DNR-X-1G CPU Core
commands that can be issued over a serial terminal.
Example code and additional documentation for programming your
application, (e.g., getting started guides, API reference, synchronization
documentation) are provided with the installation.
This section describes the memory map for the DNR-CPU/NIC core modules
(DNR-CPU-1000/DNR-CPU-1000-XX).
NOTE: DNR-CPU/NIC board revisions align with product versions. For a list of
for DNR-X-1G Series product versions, refer to Section 1.2 on page 3.
