Hi all,

I have a problem when burning the bin file into 5505 E2PROM.The error is followed:

Choose the device...
0XX - CPLD setup only
1x - NAND Flash [CSx: 2,3,4,5]
2x - NOR Flash [CSx: 2,3,4,5]
3x - SPI EEPROM [x=1: EVM, x=2: USB Stick]
4 - IIC EEPROM
5 - MMC; 6 - SD
4
Operation to perform...
0 - CPLD setup for this device
1<file> - Program device with <file>
2<file> - Read device data to output <file>
1C:\pjt\programtest.bin
IIC EEPROM...
Writing data to device...
Opening C:\pjt\programtest.bin...
Input file opened
WRITE ERROR! at 0x0000
Wrote 0x09aa Read 0x0000

The E2PROM we use is CAT24WC256, I2C Bus. 

The design is referred to the EVM5505,and the programmer is used in the EVM5505 test code.

I wonder what the reason is.

Thanks.
