Overview

Version 2.0.1 of the V6M6 software and FPGA and CPLD configurations includes the following changes:

• Updates for V6M6HS embedded code and hardware configurations.

• Bug fix in VME interface logic for V6M6 boards.

• Timing improvements for DM4C51 DSP module.

• New configuration file format for IMHC4 module.

• Source files for RC32364 support on V6M6HS boards.

• Software fix for IM2E1 and IM2T1 TDM clock generation.

• Modifications to host device drivers.

• Software modification for DM2C31 DSP modules.

• Software modifications for V6M6HS operations.

• Modifications to host support programs.

• Modifications to diagnostic programs.

Note: This release includes new flash files for FPGA and CPLD configurations and for V6M6HS embedded code. Be sure to run pciflashup after installing the software.

Updates for V6M6HS Embedded Code and Hardware Configurations

This release includes new versions of the V6M6HS boot loader code and RTEMS operating system. These are distributed in the $CAC/pci/flash directory in the files, v6m6hsb511.s3, v6m6hss511.s3 and hsrtems002.bin.

The VME bridge FPGA configuration (vmebrg17.mcs) now includes support for VME Master mode.

The P2 PCI bridge (P2CI) FPGA configuration now supports local PCI to P2CI and P2CI to SDRAM transfers. The SDRAM logic in this device is improved to operate at 2 times the PCI clock frequency.

Bug Fix in VME Interface Logic for V6M6 Boards

A bug in the logic for handling VME Bus Grant on V6M6 boards allowed two boards to become VME bus master at the same time (depending on the timing of events). This has been fixed in vmepci116.mcs for Rev-3 boards, vmepcib116.mcs for Rev-2 boards and vmepcia44.mcs for Rev-1 boards.

Timing Improvements for DM4C51 DSP Module

The PCI interface logic for the DM4C51 DSP module (dm4c5130.mcs) is modified to allow PCI bus clock rates up to 25 MHz.

New Configuration File Format for IMHC4 Module

The configuration data file for IMHC4 codec module (imhc48.mcs) is now in a format compatible with the V6M6HS base board.

Support Files for RC32364 on V6M6HS Boards

The software distribution now includes source code and other support files for the software that runs on the IDT RC32364 MIPS Processor integrated on V6M6HS boards.

The files are located in $CAC/pci/modsupport/p364.

Software Fix for IM2E1 and IM2T1 TDM Clock Generation

The host library functions that control the TDM clock generation mode for IM2E1 and IM2T1 modules had a bug that caused them to not properly set the TDM clock generation mode. The mode in which those modules generate TDM clock at 3.8 PPM faster than the faster of their two incoming derived clocks was not being set.

The host library functions, im2e1_rcvclk, im2t1_rcvclk and pci_tdm_timing in this version are fixed to perform this operation correctly.

Note: this is the same fix that is included in version 1.8.4a of the V6M6 software.

Host Device Driver Modifications

A new ioctl request is added to the V6M6/HS device drivers for SunOS, Solaris and VxWorks that allows the Address Modifier used for VME Bus Master mode to be changed. The request macro is PCI_VMEADRMOD.

The SunOS (4.1.x) device driver is fixed to properly return an EINVAL error when an unknown ioctl command is specified.

Software Modification for DM2C31 DSP Modules

The dm2c31_clock function is fixed to properly compute the DSP clock frequency on V6M6HS boards.

Software Modifications for V6M6HS Operations

Several host library functions for control operations on V6M6HS boards are modified to support new features and for consistency.

Modifications to Host Support Programs

The pciinit program has a new -H option which has it ignore certain errors when initializing V6M6HS configurations. Ignoring these errors allows the program to continue initializing the board so that flash updates may be applied.

The pciinfo program and pciserial utility support writing and displaying EEROM data to identify certain V6M6HS board configurations.

The pciflashup program now disables its byte-count pacifier for CPLD programming when its output is not going to the console or terminal window.

The pcihsmode program now invokes pciinit without the option to zero memory and with the option to not initialize multiple boards in parallel. This program is also now supported for VxWorks.

Modifications to Diagnostic Programs

The pcichip diagnostic includes testing of VME Master mode for V6M6HS boards. A new -V option may be used to disable this test. A new -m option is added to the pciburn diagnostic to disable VME master testing.

A new diagnostic, pcip2slice, tests transfers across to P2CI interface. It invokes the pcimemlsice diagnostic which is modified to support this functionality.

Minor changes to the pcifft and pciscp diagnostics allow it to run on V6M6HS boards.
