Open Defects

ID Summary
MCAL-7960 The FLS example for J7200 mcu2_1 uses a different interrupt that J721E.
MCAL-7933 ICU for mcu2_1 on J721e gets stuck
MCAL-7906 SPI test for mcu2_1 core does not finish
MCAL-7893 Timed waits in module init shall not use GetCounterValue
MCAL-5415 Issue with Tresos plugins from MCUSW_01_03_02_04_CONFIG in ETH
MCAL-5205 can_profile_app not giving CAN TX signal output on J721E HS device
MCAL-5185 MCUSW: SPI MCAL: DMA Mode is not working if length is not FIFO aligned
MCAL-5174 ICU: Timestamp API results in Incorrect Values
MCAL-5163 Eth MCAL: mcusw eth_app polling mode error
MCAL-5107 TimingValues parameter wrongly populated in Can_BaudConfigStruct and Can_FdBaudConfigStruct
MCAL-5068 [XIP]Can Profile XIP on J721E performance degradation
MCAL-5062 FLS MCAL: Code being written at two locations

Known Limitations

ID Description Workaround Comments
MCAL-5174 [ICU] Icu module TimeStamp API returns incorrect counter values. None Usage of this API will result in delta counter values, instead of absolute counter values. Please note that only preliminary testing has been performed for this module. Extensive validation is planned for future release.
MCAL-5185 [SPI] DMA mode is not working if lenght is not FIFO aligned. None Please note that only preliminary testing as been performed for this SPI DMA feature. Extensive validation is planned for future release.
MCAL-7906 [Mcal Example: Spi Example App Reports performance degradation None When testing for the Spi example on the 2_1 core for j721e/j7200 the application freezes towards the end.
MCAL-7933 Mcal Example: Icu Example App Reports performance degradation None When testing for the ICU example on the 2_1 core for j721e the application freezes towards the end.
MCAL-7960 Mcal Example: FLS Example App Reports performance degradation None The FLS example for J700 mcu2_1 uses a different interrupt that J721E. This causes the appplication to not finish when ran.

Versioning

Each package version is composed of 4 period-delimited numbers - represented here by the letters M, m, p and b [M.m.p.b]. The table below provides a descriptive reference regarding package version numbering.

Digit Meaning Description
1 (M=Major) Major revision Incremented when the new version is substantially different from the previous For example, a new module added or an existing module’s algorithm significantly altered.
2 (m=minor) Minor revision Incremented when the new version has changed but not in a major way. For example, some minor changes in the API or feature set.
3 (p=patch) Patch number Incremented for all other source code changes. This include any packaging support code.
4 (b=build) Build number Incremented for each release delivery to CM. Reset for any change to M, m or p
