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-5174 | ICU: Timestamp API results in Incorrect Values |
MCAL-5163 | Eth MCAL: mcusw eth_app polling mode error |

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 |
