Could have sworn I had this working a year or 2 ago but it's stumped me today...
I have an SPI EEPROM device on my board, and use "ee25xx_initialize" to register it as /dev/at25. That works fine. But I can't do anything with it. Unlike at25_initialize, the ee25xx_initialize doesn't return mtd_dev_s, just a success/fail, so I can't then use an FTL etc to allow me to mount it in anyway. How can I get this device mounted with some form of FS on it so I can read/write config data to it? Perhaps FTL isn't the way to go; if so, I've forgotten what is!
