Re: [Gumstix-users] VFS not finding a valid FAT FS ???

[Sean S. <sst...@se...>]

Ors,

Thank you for the idea, I wish I could say that it worked :(  I ran dd as
you suggested, redid the formatting, etc and still got the invalid media
type.  Trying to sort out this problem has lead me to
http://www.xora.org.uk/2009/08/14/omap3-sd-booting/ and tried the script on
the page.  It is a great script and now I am getting a different error that
I am hopping that someone might be able to shed some light on, the new
errors are:

FAT: bogus number of reserved sectors.
VFS: Can't find a valid FAT filesystem on dev mmcblk0

Again, thank you again any hints / suggestions!

Respectfully,

Sean Stallbaum
