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.
