Thanks Jon, I have cleared my sdcard and setup tftp/nfs etc.
The exercise has shown I have a uboot/hardware problem in that the network
is not working
If I build uboot using "cubieboard2" .... I don't even get a "link up"
If I build uboot using "A20-OLinuXino_MICRO" ... I at least get link
up...but I can't ping not can I tftp
Then I tried setting "cubietruck"
BR2_TARGET_UBOOT_BOARDNAME="Cubietruck"
and bingo.....network started working and I can at least load my kernel and
dtb blob.....unfortunately I don't see anything after "Starting kernel.... "
but at least I know which board to select when compiling uboot.
