TDA4VM: Memory Leak Tool for RTOS and LINUX

Santhiya R1

Part Number: TDA4VM

Tool/software:

Hello,

I am currently working on the TI TDA4VM platform, specifically developing and testing applications that run on both RTOS (FreeRTOS) and Linux environments.

As part of my development process, I need to ensure memory integrity and identify any potential memory leaks that could impact performance and reliability. Could you please provide recommendations on tools or methodologies commonly used for memory leak detection on both the RTOS and Linux sides of the TDA4VM

Any RTOS-specific tools or practices TI recommends for memory leak analysis.
Linux-compatible memory profiling tools that work well on the TDA4VM platform.

Thanks

Hi,

https://www.kernel.org/doc/html/v4.18/dev-tools/kmemleak.html

From Linux side the above could be used. Note that this config is not enabled by default in the SDK.

I looked into possible workarounds, but it seems like no tool is available for RTOS.

Hi,

Could u please guide me on the profiling that is available for FreeRTOS

Could you possibly be more specific about what you require from the profiling?

we are developing an application where it runs on multiple core in TI TDA4VM. We needed profiling for each TI API s.
For ex, we need to profile how much alloc(), dealloc() takes w.r.t memory management.

Would you please confirm whether any relevant discussions are started on this https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1446816/tda4vm-optimization-of-shared-memory-allocation-in-ddr-for-a72-core-on-tda4vm thread?
