Dear Wolfgang Denk, Sorry for the simple question, but I can't find the document to guide me to read file from FAT file system in NOR FLASH.

For example, I set env to: mtdids=nor0=smt300-nor mtdparts=mtdparts=smt300-nor:46...@0x00080000(sys)ro And then I can use mtdparts command to list the partition info: device nor0 <smt300-nor>, # parts = 1 #: name size offset mask_flags 0: sys 0x00480000 0x00080000 1 But I still don't know the way how to read file inside this FAT filesystem. * Which command can do this? (fatload seems can not because the interface is not known) * From which verion u-boot supports this feature? Our u-boot is based v2009.08. Do we need to update to latest one? (v2009.11-rc1) Any document you suggest me to read? u-boot/README is not enough. Thank you very much. -- Best Regards Xianwei ZENG ----Linux Fans
