Nevertheless it would be great if the experts who set up those samples would show/use the minimum required resourcesen-USTelligent Community 13Tue, 16 Jul 2024 19:39:45 GMThttps://devzone.nordicsemi.com/thread/494240?ContentTypeID=1Tue, 16 Jul 2024 19:39:45 GMT137ad170-7792-4731-bb38-c0d22fbe4515:f9da6662-4e17-4add-a03c-5886107ec59fAmanda Hsieh<p>Hi,&nbsp;</p> <p>The secure partition size is affected by the features that you have enabled. Especially crypto features have high requirements on both flash and RAM usage. The psa_tls sample enables a big list of crypto algorithms, so you will have to disable the features that you don&#39;t need based on your requirements. When you build the sample the percentage of flash usage is presented to them from the build system like this:</p> <p><span><img style="max-height:240px;max-width:320px;" src="https://devzone.nordicsemi.com/resized-image/__size/640x480/__key/communityserver-discussions-components-files/4/pastedimage1721158517519v1.jpeg" alt=" " /></span></p> <p>When you see that the flash usage is reduced as you want, you can then configure the flash partition for TF-M by setting the Kconfig configuration CONFIG_PM_PARTITION_SIZE_TFM.</p> <p>-Amanda H.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/494220?ContentTypeID=1Tue, 16 Jul 2024 16:08:24 GMT137ad170-7792-4731-bb38-c0d22fbe4515:025f4376-5bf1-48ca-81ba-66098a6e9826Amanda Hsieh<p>Hi,&nbsp;</p> <p>Thanks for the feedback.
