We have Intel's board (i7) with Linux, and we need to save some data between power off/on. I thought of using the spi flash for this (there is also eeprom, but for some reason it is read-only!).
But I am not sure what is stored in spi flash. Is it that the BIOS is saved in eeprom, and the spi flash can be used by application for any general purpose ? How can I know where is the bios saved ?
On using flashrom it seems that I can write to the flashrom, yet I am afraid that something important is already stored in the flash.
Does anyone knows what is stored in spi flash ?
