CCS/TMS320C6657: TMDSEVM6657LS: IBL EEPROM programming/ SPI NOR

Part Number: TMS320C6657

Tool/software: Code Composer Studio

Dear Sirs,

I using TMDSEVM6657LS and try to booting from SPI NOR. Firstly I have tried to program NOR and have successful result in NORWriter, but EEPROM IBL writes continuously:

"IBL: Booting from NOR" without real booting"

Then I have reprogram EEPROM with "i2crom_0x51_c6657_be.bin (pdk_c665x_2_0_5)" 

[C66xx_0] EEPROM Writer Utility Version 01.00.00.05

Writing 47888 bytes from DSP memory address 0x0c000000 to EEPROM bus address 0x0051 starting from device address 0x0000 ...
Reading 47888 bytes from EEPROM bus address 0x0051 to DSP memory address 0x0c010000 starting from device address 0x0000 ...
Verifying data read ...
EEPROM programming completed successfully

Badly, after reprogramming IBL writes nothing.. (Also I have reprogram EEPROM with mcsdk_2_01_02_06 IBL image eeprom51.bin. It's the same result.) 

Will you help me to restore IBL?!

 

POST codes are working correctly..
