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.

Yes. I didn't enable the mtdparts support. I will try it.
Do I need to write extra driver, for example something I was doing, writing FAT + MTD support?
No, you don't need any special drivers.
After I enbale CONFIG_CMD_MTDPARTS, I can get MTD partition information. For example, I set env to:
mtdids=nor0=smt300-nor mtdparts=mtdparts=smt300-nor:4608k@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.
