I2C EEPROM writer error!!!!!!!!!

Hi,geys

I just want to enumerate the PCIE.As I follow the evmc66xx-instructions.txt.

But I met a problem.I can't use the eeprom writer to write the i2crom_0x51_c6678_le.bin to the eeprom.

[C66xx_0] EEPROM Writer Utility Version 01.00.00.04
[C66xx_0]
[C66xx_0] Writing 51932 bytes from DSP memory address 0x80000000 to EEPROM bus address 0x0051 starting from device address 0x0000 ...
[C66xx_0] Returned platform error number is 4
[C66xx_0] EEPROM write failed

And I config the SW  with 

Set EVM card to PCIE boot via following switch setting
SW3(pin1, 2, 3, 4)SW4(pin1, 2, 3, 4)SW5(pin1, 2, 3, 4)SW6(pin1, 2, 3, 4)SW9(pin1)

(off, on, on, off) (on, on, on, on) (on, on, on, off) (off, on, on, on) (on)

Plz tell what's wrong with it.

Thanks
