Hello Alejandro,
You got the point! I can not used that because there is a CPLD between
my FPGA and Flash memory. In the future i probably will writhe some
OPB for that.
May romfs is already build and linked withe the kernel image, but I
will disable the MTD and see what I got.
As soon i got the result I`ll post here!
Tanks
