Calculating Memory available in DWM3001CDK

Wireless Connectivity Ultra-Wideband

Hi Qorvo Team,

I have a list to queries regarding memory usage in DWM3001CDK:

  1. Is it possible to calculate the available memory (ROM) using thread command in the CLI or by using any other method?

This is the output of thread command.

heap

Here we have observed total heap as 51200, Can we consider it as 51kb or 51mb.

  1. How to identify the RAM availability in DWM3001CDK using any FreeRTOS command?

Hi,

The THREAD command provides you only RAM memory consumption. All figures are given in Bytes.This command provides you the size of the heap and its current usage for each thread. The 3 last lines provides statistics on the heap (total available, currently used, max used).

To see values moving, you can issue this THREAD command while the device is ranging.

To see how are retrieved these statistics take a look at Libs\uwb-stack\libs\qosal\src\freertos\qprofiling.c:

  • qstackstat_get for stack statistics
  • qmemstat_get for heap statistics

For ROM consumption, the easiest is to recompile the application and get the statistics at the end of the build.
