Hi, does anyone know ADC demo on Activity Board?

Hello there, I recently tried an ADC demo (jm_adc124s021_demo - Archive) on Activity Board. The ADC uses DIN = 18, DOUT = 19, SCLK = 20, /CS = 21 and BAUD RATE = 115200. After I downloaded and ran from EEPROM, the serial terminal does not seem to display anything, and P30 LED isn't blinking to transmit data to PST. Does anyone know what is going on?
