I have tried two boards and multiple blinky examples. There is a problem shown below that dissapears when I click blinky_pwm under the build.

&lt;p&gt;Building blinky_pwm&lt;br /&gt;west build --build-dir c:/MJ/NCSv3.4.0/blinky_pwm/build c:/MJ/NCSv3.4.0/blinky_pwm --pristine --board nrf5340dk/nrf5340/cpuapp -- -DDEBUG_THREAD_INFO=On -DCONFIG_DEBUG_THREAD_INFO=y -Dblinky_pwm_DEBUG_THREAD_INFO=On&lt;/p&gt;
&lt;p&gt;&lt;/p&gt;
&lt;p&gt;This works for me and LED1 is blinking on the nRF5340 DK.&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
