I have managed to flashed a 36-bits u-boot to my p4080 board.

I have put in two 4Gb dimm into the board but it doesn't work.

I got the following from u-boot.

 

""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""

""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""

It seams that it is something wrong with the DDR initiation.

Do I have a too old u-boot?

Do you think that a newer u-boot should work?
