1. General
*************************************************************************

This Patch can be installed only to update an existing SystemDesk 25.1
installation.


2. Improvements and Fixed Problems
*************************************************************************

SystemDesk 25.1 Patch 2: 

Modeling
- Fixed an issue where an InvalidValue of an ApplicationPrimitiveDataType was
  resolved incorrectly if the CompuMethod was a type of any TEXTABLE.
- Fixed an issue where a ServiceSwComponent was incorrectly removed from the
  EcuFlatView during synchronization when its ServiceSwComponentType was not located
  under the EcuConfiguration node.

V-ECU Generation
- The default value for the BusNotifications parameter has been updated to match
  the standard.
- The EcuMFixedUserConfig symbolic names are generated in a deterministic
  alphabetical order.
- Fixed an issue where RTE interventions could cause an exception when more than
  65535 intervention IDs were used.
- Increased RxOperationBufferElementSize to 1536.
- The basic module structure for the LS-BUS LIN driver is supported.
- Fixed an issue where BSW module scripts for certain modules would fail when the
  VECU_GENERATION_PYTHON_EXECUTABLE environment variable was set.
- Fixed Sfc, Cdd, and PduR EPD files to support 3rd-party EcuC module configuration.
- Correct target configuration file is now used for A2L update.
- Fixed an issue where the Platform_Types.h file was not AUTOSAR-compliant.
- Fixed RTE read intervention points for degradated delegation ports.
- A warning message is given instead of an error message if the generated A2L
  element name exceeds 128 Char.
- Adjusted the Sab reset message to a more meaningful message when successive reset
  signals are detected.
- Fixed OsCounterMaxAllowedValue with MaxAllowedValue as uint32.
- Fixed an issue that set the EXECUTION-CONTEXT of an BswModuleEntry for a
  PROVIDED-CLIENT-SERVER-ENTRY to UNSPECIFIED instead of TASK.
- Validation of the XCP module in the FMU is now executed before XCP code
  generation.
- Adapted CAN module to support AR4.3.1 CanIfARVersion.
- The watchdog is now re-armed on each valid call to Wdg_SetTriggerCondition().

Security
- This patch contains various security fixes for dSPACE and third-party components.

2.1 Improvements and Fixed Problems by Previous Patches
*************************************************************************

SystemDesk 25.1 Patch 1: 

Modeling
- Improved rounding of scaled limit value for the A2L export.

V-ECU Generation
- This patch for SystemDesk 2025-B contains a preview version of the Ethernet
  Driver for FMI 3.0 with the Layered Standard for Network Communication
  1.2.0-alpha.2 for use with dSPACE VEOS 2025-B or other simulators compliant with
  this pre-release of the layered standard.

  The preview version of the driver implements AUTOSAR 4.1/4.2/4.3 and supports 
  basic operations such as transmission, reception and mode management.
  Limitations are that the following features are not yet supported:
  - Priorization/Filtering with multiple transmission/reception queues (All queues
    are treated equal)
  - Transmission/Reception statistics and counters
  - Time synchronization

- Improved RTE generation performance for software components with a large number
  of parameter accesses.
- Fixed the generation of invalid A2L ECU_ADDRESS values for data elements with an
  "SCALE_LINEAR_AND_TEXTTABLE" compu method.
- Reverted the change of A2L variable naming for data elements using compu methods
  with multiple compu scales (e.g., Var_1, Var_2, ... instead of Var, Var_1, ...).
- Fixed an error in the array layout of reversed application data types during A2L
  import.
- Fixed a problem where the Update COM Configuration incorrectly reported an error
  for IDTs of the TYPE_REFERENCE category.


3. Limitations
*************************************************************************

SystemDesk projects saved by this Patch cannot be opened with
previous versions of SystemDesk.


4. Installing the Patch
*************************************************************************

To install the Patch, you must be logged on with administrator rights
