My GPIO lines look like this : gpiocustomen-USTelligent Community 13Wed, 27 Apr 2022 13:02:56 GMThttps://devzone.nordicsemi.com/thread/365207?ContentTypeID=1Wed, 27 Apr 2022 13:02:56 GMT137ad170-7792-4731-bb38-c0d22fbe4515:c6cddfd9-5295-4384-95b6-28f80e9137bbAlister<p>My theory is that all 4 pins are used by the pwm2 in the dts:</p> <div><br /> <div><span>/* PWM2 is intended for NMOS transistor control */</span></div> <div><span>&amp;</span><span>pwm2</span><span> {</span></div> <div><span>&nbsp; &nbsp; </span><span>status</span><span> = </span><span>&quot;okay&quot;</span><span>;</span></div> <div><span>&nbsp; &nbsp; </span><span>ch0-pin</span><span> = &lt;</span><span>13</span><span>&gt;;</span></div> <div><span>&nbsp; &nbsp; </span><span>ch1-pin</span><span> = &lt;</span><span>14</span><span>&gt;;</span></div> <div><span>&nbsp; &nbsp; </span><span>ch2-pin</span><span> = &lt;</span><span>15</span><span>&gt;;</span></div> <div><span>&nbsp; &nbsp; </span><span>ch3-pin</span><span> = &lt;</span><span>16</span><span>&gt;;</span></div> <div><span>};</span></div> <div><span></span></div> <div><span>and I guess these over-ride any attempt to use the pin as GPIO.</span></div> </div><div style="clear:both;"></div>
