All right, maybe you should fix your method of pasting u-boot output, you have 
every second line blank and a few linebreaks here and there, randomly. It'd be 
cool to fix it, it'd make it much easier to read. Can you do something about it 
please?

You mean with the keyboard? Because "setenv stdin usbkbd" tells the system to 
read input from the USB keyboard.

Ah ... so you got no console output. Try typing on the usb keyboard. If you 
change stdin to usbkbd, you'd only be able to type with the USB keyboard, it 
won't pick input from the UART/serial port or whatever other source you use.

Pri?

btw it's a good practice in the mailing list to not top-post (aka reply under 
the email you're replying to). But if you comment on stuff, you can do it in the 
middle of the email (just like I did with this one) to better identify what 
you're replying to.
