What's New
Here is a list of the new feature(s) supported in this release:
- VPAC and DMPAC supports software monitoring for error events
- Watchdog timer enabled at line/block level for VPAC and DMPAC
- Raw-Histogram read out support for VPAC3 and VPAC3L devices
- YUV420 and YUV422 simultaneous output is supported on dual FCP for VPAC3 devices
Known Issues
ID | Summary |
---|---|
PDK-12683 | Chroma only output is not correct from Human Vision Pipeline when machine vision is enabled. |
PDK-12681 | Incorrect access of luma and chroma channel in luma only and chroma only mode causes corruption. |
PDK-13230 | Edge-enhancement mode not supported for HV-MV dual pipeline. |
PDK-13229 | CAC input for MV is not enabled in VHWA |
PDK-13247 | AEWB output incorrect for VISS for Three Frame Merge with two YUV420, saturation and AEWB output |
PDK-12860 | [VHWA-VISS]: Error check missing while setting VISS module specific configuration |
- | [VHWA]: DPC stats enable MMR is not configurable from VHWA VPAC3L. |
- | [VHWA]: DCC live tuning for AWB is not working properly on AM62A |
- | [VHWA]: GLBCE context save and restore requires validation using low level driver test case for J722S and AM62A |
PDK-16713 | [VHWA]: DOF on J784s4 platform is not meeting the expected performance |

Steps to run VHWA test applications:
cd pdk/packages/ti/drv/vhwa/
make help
VHWA example build
make vhwa_msc_baremetal_testapp BOARD=j721s2_evm SOC=j721s2 CORE=mcu2_0 BUILD_PROFILE=debug
Please note: AM62A and J722S does not support VHWA standalone test applications.

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 |
