Overview

Version 2.2.4 of the V6M6 software and FPGA and CPLD configurations includes the following changes:

• New FPGA configurations for DM4C6202, DM4C6203 and PM5000 smPCI modules.

• Changes to the DM4C6202 and DM4C6203 host API.

• Changes to files used for building DM4C6202 and DM4C6203 programs.

• Changes to diagnostic programs.

New FPGA Configurations for DM4C6202, DM4C6203 and PM5000 smPCI Modules

The timeout interval for PCI master transactions on DM4C6202 and DM4C6203 modules is increased from approximately 3 milliseconds to approximately 48 milliseconds.

The timeout interval for PCI master transactions on PM5000 modules is increased from approximately 4 milliseconds to approximately 64 milliseconds. In addition, bugs are fixed to avoid premature timeouts and to make sure that the PCI master access is actually terminated when a timeout occurs.

These changes resolve problems that can occur during diagnostic tests that generate an unusually high amount of PCI bus activity.

Changes to the DM4C6202 and DM4C6203 Host API

The dm4c62x_run library function is changed to fix a bug in the initialization of the DSP ID variables for the broadcast resource.

Changes to the Utility and Support Programs Changes to Files Used for Building DM4C6202 and DM4C6203 Programs

The makefile file found in the pci/modsupport/dm4c6202 directory are updated to allow the DSP code to be compiled with the new version of the DSP compiler from TI. The change requires that certain header files from the old version of the compiler be made available for the new compiler. These header files are used by the CAC programs but are no longer included with the new version of TI's compiler.

The dm4c6202.h file in the pci/modsupport/dm4c6202 directory has a new PCI_BURST_CTRL macro used for control the burst/no-burst mode for PCI accesses from the modules.

Changes to the Diagnostic Programs

The pciburn program is fixed to properly count the number of test cycles and quit after reaching the number specified with the -P option for systems without IMATM modules.

The DSP portion of the pcimemslice program for DM4C6202 and DM4C6203 modules, c62xslice.c, is modified to write the address and the compliment of the address for external memory tests and to NOT stop testing memory when a memory error is detected.

The c62xslice.c is also modified to allow the host application to control the setting of the BURST_CTRL register on the module. However, host programs that use this DSP program have not yet been updated to utilize this capability.
