|
||||||
|
Uboot is installed in a wrapper file called BOOT.BIN located on the root of
|
||||||
|
the SD card. To create the BOOT.BIN file do the following.
|
||||||
|
|
||||||
|
source <path/to/xilinx/settings.sh>
|
||||||
|
cat <<EOF > boot.bif
|
||||||
|
{
|
||||||
|
[bootloader]<path/to/fsbl.elf>
|
||||||
|
<path/to/system.bit>
|
||||||
|
<path/to/uboot.elf>
|
||||||
|
}
|
||||||
|

|
||||||

bootgen -image boot.bif -o i BOOT.BIN
