 1. Since I need to use PWM DMA to transfer 320 bytes of data to the PWM for sequential playback. 2. I wrote the following test example to test the nrfx pwm driver, but I haven&amp;#39;t captured the waveform of the PWM IO port.

&lt;p&gt;I built and ran your sample with SDK v3.2.4 and it seems to work fine here:&lt;/p&gt;
&lt;p&gt;&lt;img style="max-height:240px;max-width:320px;" src="https://devzone.nordicsemi.com/resized-image/__size/640x480/__key/communityserver-discussions-components-files/4/pastedimage1775823231740v1.png" alt=" " /&gt;&lt;/p&gt;
&lt;p&gt;The only change I made was to update the error check here to check for 0 instead NRFX_SUCCESS as the nrfx has been updated to use the posix error codes in this SDK release.&lt;/p&gt;
&lt;p&gt;&lt;img style="max-height:240px;max-width:320px;" src="https://devzone.nordicsemi.com/resized-image/__size/640x480/__key/communityserver-discussions-components-files/4/pastedimage1775823523331v2.png" alt=" " /&gt;&lt;/p&gt;
&lt;p&gt;Also,&amp;nbsp;if you are testing on the nrf54l DK, please note that P1.07 and P1.06 are both routed to&amp;nbsp;interface MCU by default. You can change this through the board configurator app:&lt;/p&gt;
&lt;p&gt;&lt;img style="max-height:240px;max-width:320px;" src="https://devzone.nordicsemi.com/resized-image/__size/640x480/__key/communityserver-discussions-components-files/4/pastedimage1775823718403v3.png" alt=" " /&gt;&lt;/p&gt;
&lt;p&gt;Best regards,&lt;/p&gt;
&lt;p&gt;Vidar&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
