YTM32B1MD2_SafLib_3_0_0 Release Notes

Frankie

1. Overview

YUNTU SafLib (Safety Library) provides peripheral self-tests and software safety mechanisms for AUTOSAR application integration. This document describes SafLib 3.0.0 for YTM32B1MD2.

Required dependency: MCAL 3.0.0. SafLib 3.0.0 must be integrated with MCAL 3.0.0.

1.1 Release Type

Initial Release — SafLib 3.0.0. This is the first SafLib release for YTM32B1MD2; there is no previous release.

Status: Internal Release Notes | Release Date: TBC | Issue Snapshot: 2026-10-28

1.2 Release Highlights

MD2 Module Support — Added ClkTst, CrcTst, DmaTst, EccTst, EfmTst, FlsTst, RamTst, StkTst and WdgTst adaptations with related tests.
DmaTst Configuration — Improved startup-test defaults, runtime-test configuration and DMA channel validation.
Stack Overflow Details — Added StkTst_GetDetailsResult() and its YCT switch to distinguish MSP and PSP overflow.
EccTst Interrupt Handling — Fixed application hangs when ECC flags are already pending before the test; the ISR is installed before interrupts are enabled.

[New]-[StkTst]-[0] Add StkTst_GetDetailsResult() and its YCT switch to distinguish MSP and PSP overflow
[Fix]-[EccTst]-[3] Fix EccTst application hangs caused by pending ECC flags by installing the ISR before enabling interrupts and clearing interrupts after the test

DmaTst-ISSUE-170 does not specify an effect level; it is marked TBC.

Type labels for StkTst-ISSUE-177, EccTst-ISSUE-189 are classified from the issue content because the source Type field is empty.

4. Known Issues / Limitation

4.1 Integration Notes

EccTst (EL3): Update EccTst wherever the module is used. Install the ISR before enabling ECC interrupts, then execute the test and clear interrupts. Revalidate startup and boot-to-application paths with ECC flags already pending.
DmaTst: Regenerate and review configuration for startup-test defaults, the minimum hardware-channel count, the single runtime container and channel-link constraints.
MD2 Coverage: The nine module adaptations in Section 3 do not establish support for unlisted modules. Confirm the complete module and device-variant support matrix.
Release Baseline: Confirm the 3.0.0 version record, package identifier, delivery contents and regression reports. Issue closure does not replace release-package qualification evidence.
