Channel sounding not enough memory to store step data (530 > 512)

[Triscuit]

Hi, 

I am currently working with the channel_sounding/connected_cs sample for nrf54l15 and I keep getting the error: Not enough memory to store step data (530 > 512). I tried increasing CONFIG_MAIN_STACK_SIZE but the same error still showed up. Do you have any advice on how to resolve this issue?

Hi,

Is this the default (ie. completely unmodified) version of the sample? Are you using nrf54l15 DKs? What NCS version are you using?

Hi, 

Yes, this is completely unmodified. I am using nrf54l15-dk with NCS version 3.0.0, thank you so much for your response.

Ah I see, these are the samples that comes directly from Zephyr. I guess those should work as well though I am not too familiar with them myself, could you try the ones from Nordic (these two here and here) or did you want to go for those from Zephyr? We recommend using the ones that comes directly from us.

Hi, Elfving, I started using the version you suggested, however, every time I try to build the project it says that RAS_FEAT_REALTIME_RD is not recognized. I updated to the newest sdk and everything but nothing seems to work. Thank you for your time.

Could you expand a bit on this? Are you seeing this in a build log error? Or where are you seeing this? And how is this not working?

I: Distance estimates on antenna path 3: ifft: 1.366653, phase_slope: 2.516566, rtt: 2.259156, best: 1.641056
I: AP3: best=1.64
I: Average best distance is 1.560800 meter(s)
I: Sleeping for a few seconds...
I: Ranging data overwritten 814
I: Ranging data overwritten 815
I: Ranging data overwritten 816

This is the output in the terminal when I run the code. Sometimes it spits out the distance and the other times it says ranging data overwritten.

I see. And was this with the default configuration of the sample, or with parhaps lowered the procedure_interval parameters?
