CYPRESS FM4 BOARD AND FM4 STARTER KIT error in program

Akhtar

Hello there,

I am a newbie in embedded systems, Currently I am using ARM-based Digital Signal Processing Lab-in-a-Box with Cypress FM4 board (FME-176L-S6E2CC-ETH Starter Kit) . Program is -

// loop_intr.c

#include "audio.h"

volatile int16_t audio_chR=0; //16 bits audio data channel right
volatile int16_t audio_chL=0; //16 bits audio data channel left

void I2S_HANDLER(void) { /****** I2S Interruption Handler *****/

gpio_toggle(TEST_PIN);

audio_IN = i2s_rx();
audio_chL = (audio_IN & 0x0000FFFF); //Separate 16 bits channel left
audio_chR = ((audio_IN >>16)& 0x0000FFFF); //Separate 16 bits channel right

//Process

audio_OUT = ((audio_chR<<16 & 0xFFFF0000)) + (audio_chL & 0x0000FFFF); //Put the two channels toguether again
i2s_tx(audio_OUT);

}

int main(void)
{
gpio_set_mode(TEST_PIN,Output);
audio_init ( hz48000, mic_in, intr, I2S_HANDLER);

while(1){}
}

When I try to built the target  It shows following output in Build out put window

Build started: Project: DSP_LiB
