Hello everybody,
My target is at91rm9200dk with SPI DataFlash only (no Flash). I'd like
to store environment vars in this SPI DataFlash. For Flash and Nand
there are corresponding modules: common/env_flash.c|env_nand.c. But for
Dataflash there is nothing... Should I create the module to store
environment in at91rm9200dk SPI DataFlash?
Best regards
Andrew Zhukov

Hi Andrew Zhukov,
No.
In include/configs/at91rm9200dk.h
#define CFG_ENV_IS_IN_DATAFLASH
and things work automatically. You may need to tune
#define CFG_ENV_ADDR (CFG_DATAFLASH_LOGIC_ADDR_CS0 + CFG_ENV_OFFSET)
but for your case, I think no necessary.
