boot from SPI on 6678 custom board without DDR

armin neamati

I want use spi nor flash boot mode on my 6678 custom board. In this board, I don’t use DDR memory and I’ll face some problem because of ignoring this memory. In the evaluation board I programmed spi nor flash successfully through using “eeprom51.bin” and now I want load my bin file on spi nor flash. As I know, I must load “eeprom51.bin” on eeprom and my bin file on nor flash. I changed the following line in source file “eepromwriter.c” for using MSMCSRAM memory instead of DDR.

#define WRITE_DATA_ADDRESS 0x0c000000

After that I load “eeprom51.bin” on my board’s eeprom but I faced the following error and I don’t know how can I fix this. Do you know??

[C66xx_0] EEPROM Writer Utility Version 01.00.00.05

Writing 52072 bytes from DSP memory address 0x0c000000 to EEPROM bus address 0x0051 starting from device address 0x0000 ...

Hi Raja

Thanks for your reply and forgive me for many question that I ask but I can't find true source which solve my problem except you. Really I can not detect why the problem happens. I used the same project for both board, evaluation and custom. In custom board ,which hasn't DDR3, not work and I don't know why?
