Fixed Issues

ID Description Module Affected Versions Affected Platforms
TIDL-1891 J721S2: Batch processing with a batch greater than four leads to crashes on EVM TOOL 08.04.00, 08.02.00 J721S2
TIDL-2888 Network with more than 16 subgraphs cannot be run using ONNX runtime OSRT 08.04.00 J721S2
TIDL-2899 Model compilation results in crash if 1x1 resize layer is the only layer in the network or subgraph OSRT 08.04.00 J721S2
TIDL-2910 On-the-fly padding might result in a crash for certain resize layer combinations TOOL 08.05.00 J721S2
TIDL-2943 Tflite runtime : Channel padding layer gets delegated to C7x when not supported OSRT 08.05.00 J721S2

Known Issues

ID Description Module Reported in Release Affected Platforms Occurrence Workaround in this release
TIDL-1872 Import failure for deeplabv3 (mobilenetv2 backbone) based OD+SEG Model COMPUTE 08.02.00 J721S2 Rare
TIDL-2593 OSRT : Softmax layer with non-flattened input gets delegated to C7X-MMA instead of ARM OSRT 08.02.00 J721S2 Rare Introduce a flatten layer before softmax or set softmax layer in deny_list runtime option
TIDL-2602 TF-Lite style asymmetric quantization has partial support COMPUTE 08.04.00 J721S2 Rare Reimport the model with a symmetric quantizationStyle
TIDL-2604 DRU Based weight compression results in hangs for certain weight buffer dimensions COMPUTE 08.04.00 J721S2 Rare Reimport the model with weight compression disabled

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
