Resolving "No EtherCAT Slaves Found" Error on BeagleBone AI with Embedded Linux

hey guys, am developing a real-time industrial control system using a BeagleBone AI with Embedded Linux. The system should read data from an EtherCAT torque sensor. I have verified the EtherCAT slave connection and settings, checked the network interface and cable connections, made sure the EtherCAT library is correctly installed and configured. But am getting the error No EtherCAT slaves found.

this is my code
#include <stdio.h>
#include <ethercat.h>

int main() {
    if (ec_init("eth0") <= 0) {
        fprintf(stderr, "Failed to initialize EtherCAT\n");
        return 1;
    }

    if (ec_config_init(FALSE) <= 0) {
        fprintf(stderr, "No EtherCAT slaves found\n");
        ec_close();
        return 1;
    }

    ec_config_map(&IOmap);
    ec_configdc();

    while (1) {
        ec_send_processdata();
        ec_receive_processdata(EC_TIMEOUTRET);

        int torque = ec_slave[1].inputs[0];
        printf("Torque: %d\n", torque);
        usleep(500000);
    }

    ec_close();
    return 0;
}
