Hi All, I have a media card that has one fat partition with a testfile.gzip (unrelated to the kernel). I would like to read this file and uncompress it to SD memory. Can this be done and if so, how do I achieve this? I've enabled FAT support but fatinfo requires "dev[:part]" and I'm not sure what to specify as my device and partition.
Typically "fatinfo mmc 0". The command is of the format "fatinfo
Thanks, That did it: Partition 1: Filesystem: FAT32 "NO NAME "
But how do I read from this partition then do an uncompress?
Hi Junior,
Your original message says "uncompress it to SD memory." If you are expecting to write the resulting data back to your media card (my interpretation of "SD memory"), I don't think you can get there without a lot of work.
IIRC, the file systems supported by u-boot are read-only. The expectation is that, if you want to write to a file system, you should us an operating system, not a boot loader.
I'm sorry, By SD I really ment SDRAM. Perhaps I shouls simply say "uncompress". I have 32M of ram and I'm trying to read a file into ram and uncompress it. I'm not interested in writing to the media card.
Thanks, --Jr.
