493642-2736369334 | DDR IO Margin\Training Iterator: Training failure not indicated. | When checking for the `CTRLR_READY` signal and flagging it as error if it is not HIGH, the training Iterator stage shows as failed and the tooltip reads Controller Ready Not High.
493642-2736850582 | `PF_SOC`: MSS: Option to disable SD card pins `SD_WP` and `SD_POW` in the PolarFire SoC MSS configurator. | Added the Boolean parameter `Disable SD_WP` and `SD_POW` ports below the SD usage combo box. If this parameter is enabled, ports usage is disabled. Default is false.
493642-2740070097 | The Tcl script does not have a command to import memory files. | Users can specify imported memory file information when configuring IGLOO2 TPSRAM, DPSRAM, and URAM through Tcl using the parameter `IMPORT_FILE`. This parameter accepts absolute and relative paths as inputs.

Table 13-4.Customer-reported Defects and Enhancement Requests (No Case Numbers)
Description | Resolution
--- | ---
PolarFire -1 speed-grade devices limit the maximum DDR3 GPIO rate to 800 Mbps. | The maximum rate for GPIO DDR3 for PolarFire -1 devices is 1067 Mbps
PolarFire SoC Icicle embedded programmer had a longer programming time in Linux than in Windows. | PolarFire SoC Icicle embedded programmer no longer has a longer programming time in Linux than in Windows.
The PF_IOD GUI does not allow non-integer frequencies. | The Validate rules on `DATA_RATE` for both RX and TX IOD GENERIC cores have been changed to accept floating values for `DATA_RATE`.
Instantiating a tamper macro to reset a device by asserting its `RESET` input without configuring or enabling its features causes Libero to generate an error when the `.spi` file from this image is used to configure design initialization. The error message says that the golden image cannot contain security. The tamper macro has no security feature enabled (only reset input/functionality is used) and no silicon signature and customer security is enabled. Although the SPI bitstream should not contain any security components, it does. | Users can now load an SPI file as a Recovery/Golden client in the configure design initialization tool when exported from a Libero design that instantiates the tamper macro without enabling any features.
Runtime issue for RTG4: Compile takes approximately 2 hours to complete. | Fixed algorithm to reduce runtime for this corner case.
SPI Flash init configuration and golden image with tamper macro. | The security component is not added to the bitstream if no tamper macro settings are selected. This allows the bitstream to load as a golden client.
RTG4 Global net report fanout is incorrect. | The value of the Fanout column has been corrected to show the real fanout of the net.
Construct does not allow loading of SPI Flash file automatically. | In FlashPro Express, users can now load a SPI Flash file for PolarFire and PolarFire SoC devices after creating a new job project by constructing a JTAG chain automatically.
The `PF_XCVR_REF_CLK GLOBAL` path to Fabric logic is missing. | Libero now enables the path from the XCVR Ref Clk to the Fabric.
`PF_DDR_OCTAL`: Add individual tap adjustments for multiple memory chips. | See New Post-layout Editing of I/O Attributes and Delay Parameters.
I/O registers assigned with PF_IO macro are not reported. | Compile, Pin, and IOFF reports for G5 have been updated to display I/O registers assigned with the PF_IO macro.
The SmartPower VCD + Vectorless: large frequency value is annotated after import. | The SmartPower code now annotates pin toggle rates using the correct clock domain for this corner case.
Clock and logic frequency are limited to 300 MHz. | Power estimator has been revised to allow frequencies up to 425 MHz to be specified in the Clock and Logic tabs.
Although `PCIE K_BRIDGE_SPEED` is not locked, if it had a value of 1 for `PCIE#_CONFIG_PCIE_#_K_BRIDGE_SPEED_LOCK`, it was reported as an error. | This issue has been resolved and is no longer reported as an error.
Internal Error/RTG4:Libero crashes when trying to modify Op Cond on 3.3v.. assertion at OperatingCondition.cpp", line 458. | Changing the temperature range, core voltage range, or default I/O voltage range (for all voltages) from MIL to Custom or Custom to MIL in the Project Settings UI and saving the changes no longer causes Libero to crash.
Data exported using the Record Action function is incorrect. | Record Actions now reports the proper values.
Load probe feature always opens to the default location. | SmartDebug now opens the last opened directory instead of the default location.
Charts do not show whether training fails in DDR Debug mode. | SmartDebug now displays training charts even if training fails.
A training iteration counter has been added to the SmartDebug GUI. | The SmartDebug GUI now displays an iteration counter and reports a warning when the reset counter value exceeds 10.
Incorrect result on write calibration in DDR Debug function. | SmartDebug includes additional checks to identify write-calibration failures.
`SD_WRITER`: Missing connection for bus slice. | Libero now detects missing slice nets and write assignments on component generation.
PF_IO: Complete matrix of registered versus non-registered BIDIR I/O. | Libero configurator now allows Input IOFF, Output IOFF, or Enable IOFF for bidirectional I/Os to be selected individually.
`PF_IOD_OCTAL_DDR` configuration issues. | Libero IO configurator now allows single-ended DQS to be selected for AP SRAM memory.
`PF_IOD` GUI does not allow non-integer frequencies. | The PF IOD configurator now accepts non-integer frequencies.
