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 <interface> <dev[:part]>"
Interface is important for common/cmd_fat.c function get_dev() where it calls a different function for each name. It passes the device number to a function mmc_get_dev which is probably in your cpu-specific files unless something has changed since 1.1.5. My at91 mmc/sd implementation is quite simple because I only support one device. I completely ignore the dev parameter and return a pointer for the only device available on my system.
