Loading U-Boot via JTAG
=======================

Note: This boot flow requires access to Xilinx tools (for JTAG programming).

Download the bitstream for the target machine using JTAG (The pre-built
bitstream provided in the reference design files should be used).

(MicroBlaze) Download the 'u-boot.elf' to the target CPU via the use of XMD.
	$ xmd
	XMD% connect mb mdm
	XMD% rst
	XMD% dow u-boot.elf
	XMD% con

(Zynq) Download the 'u-boot.elf' to the target CPU via the use of XMD.
(Note: Ensure to have the boot mode pins/switches configured in JTAG mode)
	$ xmd
	XMD% connect arm hw
	XMD% rst
	XMD% dow zynq_fsbl_0.elf
	XMD% con; sleep 1; stop
	XMD% dow u-boot.elf
	XMD% con

U-Boot will load and the console will be avaliable on the UART interface.
