Upgrade and Compatibility Information

Modules/Topic	Compatibility	Remarks
TI Arm Clang Compiler	V3.2.0	NA
EB Tresos Studio	V24.0.0	NA
Build	gmake	NA
MCU+ SDK	mcu_plus_sdk_09_01_00_39	The MCAL examples are built and validated on mcu_plus_sdk_09_01_00_39 version. Refer to respective version of MCU+SDK User Guide to setup the EVM.

Compatibility

Please note that the MCAL Release Versioning has changed and now is in accordance with AUTOSAR requirement SRS_BSW_00321. The MCAL Module Version number (Major.Minor.Patch) is updated only during release cycle based on the change in source/compatibility with previous release. MCAL Modules will not have a common version number. MCAL Package release version and the Bundle Version of the configurator plugins will be updated for each new release.

Details based on SRS_BSW_00321. The Version numbers of MCAL AUTOSAR Basic SW Modules shall be enumerated according to the below rules:

Increasing the more significant digit of a version number resets all less significant digits.
PATCH_VERSION is incremented if the module is still upwards and downwards compatible (ex. Bug fixes).
MINOR_VERSION is incremented if the module is still downwards compatible (ex. valid functionality added).
MAJOR_VERSION is incremented if the module is not compatible any more (ex. existing API valid).

IMPORTANT NOTE: User should ensure to use below modules version for MCAL_SitaraMPU_09.01.00 release. User should take care to not mis-match or mix-and-match the versions with various MCUSW releases. Bundle Version of all plugins is 9.1.0.

Fixed Issues

ID	Issue Summary
MCAL-19768	MCU - Incorrect configuration symbolic name is used for POR. Now Updated to “McuConf_McuResetReasonConf_MCU_POWER_ON_RESET” for respective parameters.
MCAL-19777	CDD_IPC-Unused Memory Mapping sections are included.
MCAL-11010	SW dependency of mcusw on MCU+SDK to be highlighted in Documentation.
MCAL-15638	Size attribute defined twice for MPU regions in startup file.
MCAL-21039	Old checksum information maybe still existed and if not clear can corrupt non IP packet
MCAL-15806	MDIO requires 32-bit preamble (all ones) to be sent before any register operation
MCAL-13836	Register readback feature for Eth is missing
MCAL-8550, MCAL-16042	MDIO errata i2329 access need to be optimized to reduce the number of MDIO register access
MCAL-10658	Custome tistdtypes inside Eth driver cuase compiler errors
MCAL-16258	User needs a bigger number of user data buffer(at least 1024)
MCAL-16259	Zero-copy and standard packet transmission cannot coexist, zero-copy API always returns fail

Open Defects

ID	Variant	Severity	Summary	Comments
MCAL-10425	AM62Ax AM62Px	S2-Major	IPC-CDD: Validation of DM R5 is pending due to issue in core communication.	Recommended to use A53 to R5 communication.
MCAL-17617	AM62Px	S3-Minor	FLS: Blank Check and Compare API is not fully functional.	Recommend user to use Fls_Read in their application to implement blank check and compare until the bug is fixed in future release.
MCAL-19356	AM62Px AM62Ax AM62x	S3-Minor	Compiler Warnings are suppressed using the CFLAGS such as -Wno-extra, -Wno-exceptions, -Wno-unused-function.	This shall be revised in the future release.
MCAL-22427	AM62Px AM62Ax AM62x	S3-Minor	Mcu_GetResetReason for POR is not supported because the recommended Reset sequence is not followed.	Mcu_GetResetReason currently does support warm reset. This will be fixed in future release.

Known Limitations or Open Points

ID	Description	Workaround	Comments

NA	AM62x: CAN: MCU_MCAN0 and MCU_MCAN1 Does Not Support Interrupt Mode. Only Main MCAN0 Shall Support Interrupt	Polling mode should be used.	User shall Configure MCU domain CAN instances with polling mode and MAIN domain CAN instance with INTERRUPT/POLLING as per requirement.
NA	AM62x/AM62Ax: ETH : Ethernet Driver has SDK dependency for SciClient	NA	NA
MCAL-9620	AM62x/AM62Ax: Spi_AsyncTransmit cannot transmit more than 32 bytes	NA	NA
NA	FLS driver only validated on AM62x/AM62Px EVM due to HW limitations on AM62Ax.	FLS driver supports OSPI NOR.	OSPI NAND is not supported.
MCAL-12891	FLS Interrupt mode is not working.	User Shall configure Flash driver in polling mode.	NA
MCAL-10425	CDD IPC supported between MCU R5 and A53 core only.	None	MCU R5 to DM R5 communication is a limitation. Applicable only for AM62Ax/AM62Px.
NA	Compliance Support Package: Please note that some safety documentation will be in Draft state as third-party certification is pending.	NA	The final certified version of these documents will be updated along with the Safety Certificate and Audit Reports in future release.
