MPC8323 application support

Hi,

I am using MPC8323E-RDB Board. I am using LTIB for building file system and kernel images I want to store some parameters regarding to my application by using files. But total flash is using for booting. Can you suggest where i can store these files into ROM memory for retaining the parameters? Is that board can retain any parameters after resetting?

Looking to board schematic, I see only two memories (see page 4) - flash memory and small eeprom "M24256" connected to I2C interface. So, if your flash in totally used, than the only option is this eeprom. Yes, eeproms retain data after resetting.

Have a great day,
Alexander

Sorry, what do you exactly mean by "able to write into flash but not able to read" - how exactly you come to the conclusion that you are able to write, if you do not have a possibility to read and, therefore, verify that write operation is successful?
