Hello Wolfgang, thank you so much. I have got another question :-) If I see under the fs/ the yaffs2/ and the ubifs/ folders I can assume that I can read and write them from uboot or there are some limitations like I can read but I can't write ? In the U-Boot website I was not able to find a list of filesystem supported, my fault I guess. Best Regards, Pietro. _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
