[U-Boot-Users] tftpboot of multi image

Bob,

I tried this and it worked:

=> setenv bootcmd tftp 01000000 uImage.multi\; setenv bootargs root=/dev/r
am rw console=ttyS0,38400\; bootm 01000000
=> boot

(adapt it for your board... remember to saveenv before boot if you want it
to persist)

I actually wished there was a way to obtain IP etc. config from dhcp
server without booting. That way I could have more control the image to
boot from u-boot environment. It could also allow me to quickly enable
network access when dhcp server is available on the network for testing
etc.

Best regards,
Tolunay
