A Question about SPI boot

patrick NA

I am a new starter with 6678 cores. As you know one of the most important project is boot programming. In my custom board I used SPI nor flash but unfortunately I didn't consider EEPROM. So I should boot SPI directly and I have some question about it:

1) Is DDR necessary for boot NOR flash?

2) How can I build bin file for programming NOR flash?

3) It seems a dat file is provided for making bin file for EEPROM("post_romparse.bat"), Is there any similar dat file for making NOR bin file?

Thanks a lot.

Hi Patrick,

1) Is DDR necessary for boot NOR flash?

No.

2) How can I build bin file for programming NOR flash?

3) It seems a dat file is provided for making bin file for EEPROM("post_romparse.bat"), Is there any similar dat file for making NOR bin file?

Please refer the attached keystone I boot loader workshop for direct SPI boot example.
