It's not happy with your USB stick. Try reformatting it & load the files again
You can also do, from the Marvell prompt
fatls usb 0
And see what is on the stick
Gosh this is getting to be so annoying
Trying it again now thanks for bearing with me!
Fatls USB 0
Taking an age to do anything but I live in hope , thanks for the advice will report if it finds anything with this command.
Has finally came back with the following
device NOT ready
Request sense returned 00 00 00
** can't read from device 0 **
** unable to use USB 0:1 for fatis **
Can I ask the relevance of the 0:1 please?, and thanks for your help on this great of you.
