Hi everyone I was implementing RL Flash_FS for my Nand Flash(k9F2G...)in lpc1788 Board. I wrote a Driver and Write functions name in const NAND_DRV nand0_drv . Configure my Settings in File_config.c . In my initialization I Setup Page layout too. Write ,Read , erase all works. But when I call finit("N0;") it always return 2 . I am sure that in its process it calls Init and Read functions , and in both it gets RTV_NOERR . So My question is :Is there any other thing I should do?! I will appreciate your helps or any sample could help in this project
