Hello All.

A simple question. Is it posible read a file on fat32 USB memory
device from barebox?

If not, is it posible write some code to do this? What steps will be necessary?
- port from linux kernel usb-storage support.?
- port form linux kernel fat 32 support?

My final objetive is firmwarize the board from a USB fat32 USB memory
device with a new barebox "firmwarize" command because I am surprised
that there is not on barebox?

Thanks in avance

No, currently not.

This is surely possible, though you might be better off with the U-Boot
code as a template for porting. You'll probably also need dos
partitioning support.

I think you don't need an extra command to do this once all necessary
code is in place. It's more a matter of a script like 'usb; mount -tfat
/dev/xxx /mnt; cp /mnt/xy /dev/nor0.kernel;'
We don't have this at the moment because nobody needed it yet. We mostly
use networking or dfu (device firmware update) for updating purposes.
That said patches are very welcome ;)

Thanks Sascha. But cp command didn't run on NOR flash . unprotect and
erase run ok so I thought cp command is not a good command to write on
NOR flash. I must revise NOR device code when I have time.


Thanks again.

It's supposed to run, otherwise it's a bug.

That is (atleast in part, no extended partitions) already there. The x86 
target has DOS partition support. And i have EFI GUID partition support 
here, that should be merged as soon as i have time to clean it up.


Both things probably should than be moved out of the x86 target and 
moved to a more generic place.
