https://devzone.nordicsemi.com/f/nordic-q-a/42181/gpio-setup-for-custom-board-fanstel-remap-of-ledsI have created a custom board in the boards.h file. I then created the fanstel header file and copied the PCA10056 information accross. Everything is working as it should except im having trouble with P1.00. I looked at this post https://devzone.nordicsemien-USTelligent Community 13Sat, 12 Jan 2019 12:19:57 GMThttps://devzone.nordicsemi.com/thread/165291?ContentTypeID=1Sat, 12 Jan 2019 12:19:57 GMT137ad170-7792-4731-bb38-c0d22fbe4515:bcb8474c-299a-4ce7-b8e1-25d2e84565a2melt<p>Thanks Kenneth,&nbsp; Its only 1 LED I suppose I can address&nbsp;it from the list.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/164365?ContentTypeID=1Mon, 07 Jan 2019 17:18:21 GMT137ad170-7792-4731-bb38-c0d22fbe4515:46049dd6-021b-491a-86c0-acea82b8d682Kenneth<p>Looks like the hal_leds_init() will presume the LEDs are chronologically ordered from LED_START to LED_STOP, in other words it will set pins P0.11, P0.12, P0.13... P0.31, P0.32(!) as output LEDs. It also seems to only support PORT0 (=NRF_GPIO I presume). The implementation of <span>hal_leds_init()&nbsp;</span>doesn&#39;t look as it supports what you want to do. I believe you need to use&nbsp;bsp_board_led_on() or&nbsp;bsp_board_led_off(), which will select a LED from&nbsp;LEDS_LIST, numbered from 0 (=LED_1) to 1(=LED_2) in this case.</p><div style="clear:both;"></div>
