The memory question of the nrf5340 audio application

Hello again and sorry about the wait, I was OOO for a while and assumed some of my coworkers would take this case in the meantime.

Yes, I need to add some audio algorithms that require memory to store and process the audio data. When I allocated the memory like this, I encountered these strange problems.

Could you check the CPU usage number to make sure the issue is not from allocated RAM but because your own code is consuming CPU? This is worth checking.

Enabling the thread analyzer might also make it easier to see:

CONFIG_THREAD_ANALYZER=y

CONFIG_THREAD_ANALYZER_USE_PRINTK=y

CONFIG_THREAD_ANALYZER_AUTO=y

CONFIG_THREAD_ANALYZER_AUTO_INTERVAL=5

And how is the RAM allocated?

Regards,

Elfving

Hello,

I'm looking into it.

During my test of the nrf5340 audio application which in the V2.6.0 SDK, Because of that i need to implement some algorithms in it, i use the ld file to allocated a segment of RAM space and init the heap as following images and added it to the CMakeList.txt.

Any particular reason that you'd want to use ld files for this? The partition manager is typically the way to go for this.
