We, have an Intel starta NOR flash which uses cfi command set driver, which basically i guess takes care of the erase operation too. I have accessed the target through minicom tool, is this where i have to set up an additional partition?, can you suggest any site or procedure by which I can acheive setting up an additional partition. Yes, Thomas has suggested that i indeed use a filesystem, but how can I best achieve it! I mean the procedure to store data in a file.
