TDA4VM: TDA4VM chip DSP resource exception

xueming tian
Intellectual 631 points
Part Number: TDA4VM

Problem phenomenon: When the application runs on the A-core, it will call the resources of the DSP. After the A-core program exits abnormally, it cannot provide information to the DSP, resulting in abnormal application functionality after the application restarts due to the unreleased DSP resources.

TI support is required:

1. Please confirm with TI whether this issue is a known issue.

2. Do TI have any relevant mechanisms to avoid such issues.

3. Do TI have relevant log records, storage locations, etc. for this type of problem

    Hi Xueming,

    What OS are you using on the A72 core? And what SDKs are you using?

    Please also share some details about the application. Is this an application coming from TI SDK, or is this your custom application.

    regards
