Initiate a read buffer job.

spi_read_buffer_job(&spi_slave_instance, buffer_rx, BUF_LENGTH, 0x00);

Wait for the transfer to be complete.

while(!transfer_complete_spi_slave) {
    /* Wait for transfer from master */
}

Compare the received data with the transmitted data from SPI master.

for (uint8_t i = 0; i < BUF_LENGTH; i++) {
    if(buffer_rx[i] != buffer_expect[i]) {
        result++;
    }
}

Infinite loop. If the data is matched, LED0 will flash slowly. Otherwise, LED will flash quickly.

while (true) {
    /* Infinite loop */
    if (result) {
        port_pin_toggle_output_level(LED_0_PIN);
        /* Add a short delay to see LED toggle */
        volatile uint32_t delay = 30000;
        while(delay--) {
        }
    } else {
        port_pin_toggle_output_level(LED_0_PIN);
        /* Add a short delay to see LED toggle */
        volatile uint32_t delay = 600000;
        while(delay--) {
        }
    }
