Test Reports Conformance test reports, TI platform test reports [FOLDER]
Software Manifest Licenses, terms of use [HTML]

What's New

ID Summary
TIOVX-1137 TIOVX shall support multiple C7X tasks running at different priorities
TIOVX-1135 Support for a way to identify if node is replicated or not on target side
TIOVX-1089 TIOVX shall support migration to LLVM/TI CLANG
TIOVX-1088 TIOVX shall support Free RTOS as a platform layer for C66/C7 DSP's

Upgrade and Compatibility Information

File Change description User application change required User application recompile required
include\TI\tivx.h Includes tivx_soc.h, which includes soc specific header file based on SOC_(soc_name) #define. For any application that includes tivx.h, it will now need to define one of (SOC_J721E or SOC_J721S2). YES YES
kernels_j7\include\TI\j7.h This file is deprecated and will be removed in PSDK 8.2 ... please remove its inclusion and just include TI/tivx.h. YES YES
include\TI\tivx_target_kernel.h Additional function declaration added: tivxIsTargetKernelInstanceReplicated NO YES
include/TI/tivx_config.h Changed #if defined(J6_VSDK) to #if defined(SOC_J6) NO YES

Device Support

Package 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
