PWM FSP code not working in ARDUINO UNO R4 WIFI

Question

I decided to program a PWM using an ARDUINO UNO R4 WIFI. I tried to configure the RENESAS RA4M1 microcontroller with the FSP libraries through the Arduino IDE. What I want to do is generate a PWM and commute a LED connected to the pin 107 of the RENESAS (ARDUINO D5~), but the code doesn't work. Here is my code:

#include "common_data.h"
#include "hal_data.h"
#include "vector_data.h"
void setup() {
 clock_cfg();
 gpio_cfg();
 pwm_cfg();
}
void loop() {
}
 // Clock configuration function (user defined)
void clock_cfg() {
 static cgc_instance_ctrl_t cgc_instance_ctrl;
 static cgc_cfg_t cgc_cfg;
 static cgc_clocks_cfg_t cgc_clocks_cfg;
 static cgc_divider_cfg_t cgc_divider_cfg;
 cgc_divider_cfg.sckdivcr_b.pclkb_div = CGC_SYS_CLOCK_DIV_1;
 cgc_divider_cfg.sckdivcr_b.pclkd_div = CGC_SYS_CLOCK_DIV_1;
 cgc_divider_cfg.sckdivcr_b.iclk_div = CGC_SYS_CLOCK_DIV_1;
 cgc_divider_cfg.sckdivcr_b.pclka_div = CGC_SYS_CLOCK_DIV_1;
 cgc_divider_cfg.sckdivcr_b.pclkc_div = CGC_SYS_CLOCK_DIV_1;
 cgc_divider_cfg.sckdivcr_b.fclk_div = CGC_SYS_CLOCK_DIV_1;
 cgc_divider_cfg.sckdivcr_b.bclk_div = CGC_SYS_CLOCK_DIV_1;
 cgc_clocks_cfg.system_clock = CGC_CLOCK_HOCO;
 cgc_clocks_cfg.divider_cfg = cgc_divider_cfg;
 cgc_clocks_cfg.loco_state = CGC_CLOCK_CHANGE_STOP;
 cgc_clocks_cfg.moco_state = CGC_CLOCK_CHANGE_STOP;
 cgc_clocks_cfg.hoco_state = CGC_CLOCK_CHANGE_START;
 cgc_clocks_cfg.mainosc_state = CGC_CLOCK_CHANGE_STOP;
 cgc_clocks_cfg.pll_state = CGC_CLOCK_CHANGE_STOP;
 cgc_clocks_cfg.pll2_state = CGC_CLOCK_CHANGE_STOP;
 R_CGC_Open(&cgc_instance_ctrl, &cgc_cfg);
 R_CGC_ClocksCfg(&cgc_instance_ctrl, &cgc_clocks_cfg);
}
 // PWM configuration function (user defined)
void pwm_cfg() {
 static gpt_instance_ctrl_t gpt_instance_ctrl;
 static timer_cfg_t gpt_cfg;
 static gpt_extended_cfg_t gpt_extended_cfg;
 static uint32_t period = 48000000;
 static uint32_t duty = 24000000;
 static uint8_t channel = 0;
 gpt_extended_cfg.gtioca.output_enabled = true;
 gpt_extended_cfg.gtioca.stop_level = GPT_PIN_LEVEL_LOW;
 gpt_extended_cfg.gtiocb.output_enabled = false;
 gpt_extended_cfg.gtiocb.stop_level = GPT_PIN_LEVEL_LOW;
 gpt_extended_cfg.start_source = GPT_SOURCE_NONE;
 gpt_extended_cfg.stop_source = GPT_SOURCE_NONE;
 gpt_extended_cfg.clear_source = GPT_SOURCE_NONE;
 gpt_extended_cfg.capture_a_source = GPT_SOURCE_NONE;
 gpt_extended_cfg.capture_b_source = GPT_SOURCE_NONE;
 gpt_extended_cfg.count_up_source = GPT_SOURCE_NONE;
 gpt_extended_cfg.count_down_source = GPT_SOURCE_NONE;
 gpt_extended_cfg.capture_filter_gtioca = GPT_CAPTURE_FILTER_NONE;
 gpt_extended_cfg.capture_filter_gtiocb = GPT_CAPTURE_FILTER_NONE;
 gpt_cfg.mode = TIMER_MODE_PWM;
 gpt_cfg.source_div = TIMER_SOURCE_DIV_1;
 gpt_cfg.period_counts = period;
 gpt_cfg.duty_cycle_counts = duty;
 gpt_cfg.channel = channel;
 gpt_cfg.p_callback = NULL;
 gpt_cfg.p_context = NULL;
 gpt_cfg.p_extend = &gpt_extended_cfg;
 R_GPT_Open(&gpt_instance_ctrl, &gpt_cfg);
 R_GPT_Start(&gpt_instance_ctrl);
}
void gpio_cfg() {
 static ioport_instance_ctrl_t ioport_instance_ctrl;
 static ioport_cfg_t ioport_cfg;
 R_IOPORT_Open(&ioport_instance_ctrl, &ioport_cfg);
 R_IOPORT_PinCfg(&ioport_instance_ctrl, BSP_IO_PORT_01_PIN_07, IOPORT_CFG_PERIPHERAL_PIN | IOPORT_PERIPHERAL_GPT0);
}

I have checked that the clocks are being configured since the "delay()" prebuild function is being affected when commuting the LED when I change the system clock divider. Also the GPIO can be configured if activated manually by setting the pin in output direction:

R_IOPORT_PinCfg(&ioport_instance_ctrl, BSP_IO_PORT_01_PIN_07, IOPORT_CFG_PORT_DIRECTION_OUTPUT);

And writting to it with the function:

R_IOPORT_PinWrite(&g_ioport_ctrl, BSP_IO_PORT_01_PIN_07, BSP_IO_LEVEL_HIGH);

Mysteriously for me, the pin is not outputting the PWM I want to commute the LED as described in the code above. Anyone can tell me what I am doing wrong please?
