https://devzone.nordicsemi.com/f/nordic-q-a/114814/disabling-printkHello, After migrating from NCS 1.8.0 to the latest NCS 2.7.0 version, I am no longer able to disable PRINTK , which we previously did to reduce flash memory usage, as we were critically close to the limit. Currently, I am unable to achieve this.en-USTelligent Community 13Wed, 18 Sep 2024 12:36:53 GMThttps://devzone.nordicsemi.com/thread/502939?ContentTypeID=1Wed, 18 Sep 2024 12:36:53 GMT137ad170-7792-4731-bb38-c0d22fbe4515:bdf70fa1-fd70-4233-8f29-f050264e8ed7Vidar Berg<p>Hello,</p> <p>PRINTK and EARLY_CONSOLE are selected by&nbsp;CONFIG_NCS_BOOT_BANNER and&nbsp;CONFIG_BOOT_BANNER, so these need to be disabled as well. If you want to disable the console and logger output, you can add the following lines to your project configuration file:</p> <p><pre class="ui-code" data-mode="text">CONFIG_LOG=n CONFIG_CONSOLE=n CONFIG_PRINTK=n CONFIG_UART_CONSOLE=n CONFIG_NCS_BOOT_BANNER=n CONFIG_BOOT_BANNER=n</pre></p> <p>Best regards,</p> <p>Vidar</p><div style="clear:both;"></div>
