TMDXEVM5515: Spirom example code doesn't work

hello,

I am using EVM TMS320C5515 REVD. I am running both example code as below from ccsv4 and ccsv6. But both of them don't work. The errors are the same. The reading content doesn't match the write(spi_eeprom_test failed: Buffers not Matching). I checked the CS pin and CLK pin. CS pin is high which is supposed to be low and CLK pin is high which supposed to have clk signal. Could you help to make this demo code working? Thanks in advanced.
