How to read and write GPIO pins on nRF5340
#gpio
Hello, Can someone please tell how to read/write to GPIO pins (ports P0 and P1)? I am using zephyr and NRF Connect v1.30 Thank you. Kind regards Mohamed Belaroussi

Ok, found the issue: It was do to pin mapping naming. I was assuming that the pinmaps in Arduino D5, D6, and so on, corresponded to a direct GPIO map, so D5->GPIO_5 and so on... and that's not true. A

Have you done the initialization by running gpio_pin_configure with GPIO_OUTPUT_ACTIVE as third argument ? Just to be clear, you´re trying to set pin p0.05 ? That´s located on chip pin7 (QFN48 pkg) ?

Hi, No MCUBoot. And yes, the board boots correctly and I can use GDB to debug. I can see the GPIO driver calls, the values that are set and so on. My prj.conf file is as simple as it can get: CONFIG_G

Are you sure that your board boots correctly? ( debug through gdb or just simple serial output ) What version of the SDK are you using? Is MCUBoot activated in your prj.conf?
