Is there any driver available for serial EEPROM or flash devices like the AT24Cxxx (I2C) or AT25Fxxx (SPI) series parts? In particular, I want to use such a part with Redboot, so that I can store a boot script and other configuration data in it.
This is for an AT91RM9200 system, which has an on-board boot ROM that can boot a 16KB program from serial EEPROM. I figure I'll write a small bit of code that sits in the beginning of the EEPROM; it will enable SDRAM, and load Redboot from the next piece of the EEPROM; the tail end of the EEPROM will hold the boot script and the configuration data. The application will boot from a much larger SD card. Do I need to write my own driver, or has anyone already done this? Or is there some reason it can't be done? The v2 flash docs imply that there's no requirement that the device actually be memory-mapped flash. -- Ciao, Paul D.
