I use a CM-X255 with a NAND Flash of 512 Mo where roughly 250 Mo are used (90 Mo for the native distribution provided by Compulab and 160 Mo for specific applications). At the boot, there's a scanning of the MTD1 (4096 blocks) corresponding to the NAND Flash. This scanning takes 1mn20s. The full boot time, from a reset to the login prompt, takes 4mn. I hope that these precisions can be useful. Thanks for any help or suggestion.
