nRF 52810 reset with PA

Question

Hi,

I'm sorry to borther you in your holiday.I got a issuse about 52810 (s112) with PA.I found my device would reset when I call ble_advertising_start() after calling pa_lna_init().The device work fine without calling pa_lna_init().There are 3 ports that I need to use them with interruption,the interruption of ports will affect the PA?What do I miss?There are my code below.

#include <stdint.h>
#include <string.h>

#include "ble.h"
#include "app_error.h"
#include "nrf_drv_gpiote.h"
#include "nrf_drv_ppi.h"
#include "nrfx_ppi.h"

#include "pa_lna.h"

void pa_lna_init(uint32_t gpio_pa_pin, uint32_t gpio_lna_pin)
{
    ble_opt_t opt;
    uint32_t gpiote_ch = NULL;
    ret_code_t err_code;        

    memset(&opt, 0, sizeof(ble_opt_t));
    
    err_code = nrf_drv_gpiote_init( );
    if(err_code != NRF_ERROR_INVALID_STATE)
        APP_ERROR_CHECK(err_code);
    
    err_code = nrf_drv_ppi_init( );
    if(err_code != NRF_ERROR_MODULE_ALREADY_INITIALIZED)
        APP_ERROR_CHECK(err_code);
    
    nrf_ppi_channel_t ppi_set_ch;
    nrf_ppi_channel_t ppi_clr_ch;
    
    err_code = nrf_drv_ppi_channel_alloc(&ppi_set_ch);
    APP_ERROR_CHECK(err_code);
    
    err_code = nrf_drv_ppi_channel_alloc(&ppi_clr_ch);
    APP_ERROR_CHECK(err_code);

        }
        
        // PA config
        opt.common_opt.pa_lna.pa_cfg.active_high = 1;   // Set the pin to be active high
        opt.common_opt.pa_lna.pa_cfg.enable      = 1;   // Enable toggling
        opt.common_opt.pa_lna.pa_cfg.gpio_pin    = gpio_pa_pin; // The GPIO pin to toggle tx  
    }
    
    if(gpio_lna_pin != NULL)
    {
        if(gpiote_ch == NULL)
        {
            err_code = nrf_drv_gpiote_out_init(gpio_lna_pin, &config);

    }

    // Common PA/LNA config
    opt.common_opt.pa_lna.gpiote_ch_id  = (gpiote_ch - NRF_GPIOTE_BASE) >> 2;   // GPIOTE channel used for radio pin toggling
