Do the basic R/W operations works? Here is the first test I do on my platforms. After I passed this, everything else seems to worked pretty good (writing large files). $ flash_eraseall -j /dev/mtd4 $ mount -t jffs2 /dev/mtdblock4 /mnt $ echo "hello" > /mnt/hello.txt $ sync If the Flash was recognized at boot, then we know that the ID command (0x9F) at least worked. Meaning read commands were at least working (which is the difficult one for this HW...writing is easier) Chris
