P1.00 with CONFIG_BT in NCS2.0

[yoyou]

Hello

NCS2.0.2, nRF5340, VScode

i can't read button P1.00.

#include <zephyr.h>
#include <device.h>
#include <drivers/gpio.h>
#include <hal/nrf_gpio.h>
#include <hal/nrf_gpiote.h>
#include <nrfx_gpiote.h>
#include <sys/reboot.h>



void main(void)
{
	printk("Hello World! %s\n", CONFIG_BOARD);
	nrf_gpio_cfg_input(0x20,GPIO_PIN_CNF_PULL_Disabled);

	while(1)
	{
		int vi1=nrf_gpio_pin_read(0x20);
		printk("*button P1.00=   %d  \n",vi1);
		k_msleep(500);
	}
}

prj.conf

CONFIG_BT=y

CONFIG_BT_OBSERVER=y

CONFIG_BT_BROADCASTER=n

CONFIG_BT_EXT_ADV=y

CONFIG_BT_PER_ADV_SYNC=y

CONFIG_BT_DEBUG_LOG=y

 

if remove CONFIG_BT,  button P1.00 will read ok;

how to slove it ?

Hello,

Not sure what board you are using, but typically 1.00 is used by logging (UART) for the netcore:
https://github.com/nrfconnect/sdk-zephyr/blob/main/boards/arm/nrf5340dk_nrf5340/nrf5340dk_nrf5340_cpunet-pinctrl.dtsi

Hi,

thanks for reply,

zephyr/boards/arm/nrf5340dk_nrf5340/nrf5340dk_nrf5340_cpunet-pinctrl.dtsi

Board is  nRF5340DK, P1.00 connect to vdd

i've changed the pin number.

even

then rebuild and reboot 5340 device,  the same can't read P1.00.

  

Best regards

I can see that by default the application core will also forward control over this pin from the application core to the network core in the nrf-gpio-forwarder: https://github.com/nrfconnect/sdk-zephyr/blob/main/boards/arm/nrf5340dk_nrf5340/nrf5340_cpuapp_common.dts#L107 

So you will need to change this also.

have you try it?

Hello,

Looks like you also need to make a <your_project_folder>\hci_rpmsg\prj.conf file, this conf file should contain:

CONFIG_BT_CTLR_DEBUG_PINS_CPUAPP=n
