Re: [Gumstix-users] Updated x-load on nand flash

Do you use the non-signed version for convenience, or a specific reason.
I was using x-load-overo.bin.ift...

It requires hardware ECC mode and several copies should (must?) be
written.  I 
happened to have my init document open when I saw your e-mail.

mw.l $loadaddr ffffffff 2000
if fatload mmc 0 $loadaddr x-load.bin; then
   echo "Replacing X-Loader"
   nandecc hw
   nand erase 0 80000
   nand write $loadaddr 0 20000
   nand write $loadaddr 20000 20000
   nand write $loadaddr 40000 20000
   nand write $loadaddr 60000 20000
else
   echo "MISSING X-LOADER"
fi
