This file describes how to reprogram the content of the 128Mb
|
|
QSPI boot flash on the Parallella board.
|
|
|
|
-------------------------------------------------------------------------
|
|
Directory Content:
|
|
|
|
parallella.bin (bootable flash image)
|
|
parallella.bit.bin (u-boot loadable bitstream)
|
|
fsbl.elf (First Stage Boot Loader)
|
|
uboot.elf (U-Boot application)
|
|
stub.tcl (tcl script for putting the CPU in debug mode)
|
|
ps7_init.tcl (FSBL settings as tcl script for JTAG operation)
|
|
|
|
The u-boot.elf is compiled from the parallella-uboot repository using the arm
|
|
gcc compiler.
|
|
|
|
The fsbl.elf is generated from the Xilinx tool chain
|
|
|
|
The parallella fpga bit files are generated by the Xilinx tool chain.

|
|
|
Pre-requisites:
|
|
-Xilinx Platform USB Cable II
|
|
-Serial port console cable
|
|
-Xilinx tools installed
|
|
|
|
--------------------------------------------------------------------------
|
|
|
|
1. Make sure you have xilinx tools installed and you have the
|
|
correct path set. For example:
|
|
|
|
my-machine:~> source /opt/Xilinx/14.4/ISE_DS/settings64.csh
|
|
my-machine:~> set path = (/opt/Xilinx/14.4/ISE_DS/PlanAhead/bin $path)
|
|
|
|
2. Connect a console cable to the three pin serial port header and a computer.
|
|
running a console application such as putty or tera term.
|
|
|
|
3. Connect the Xilinx Platform USB II cable to the JTAG PEC_POWER pins. (Note
|
|
that you will need a PEC_POWER breakout board for this). Connect the
|
|
JTAG cable to the Linux based computer running the Xilinx software. There
|
|
may be a driver conflict between the Xilinx cable and the serial cable so
|
|
the safe bet is to connect the cables in step 2 and 3 to separate computers.
|
|
|
|
4. Power on the board
|
|
|
|
5. Start the JTAG debugger on machine connected to JTAG cable:
|
|
|
|
my-machine:~>XMD
|
|
|
|
6. Enter the following command sequence in XMD to run the u-boot application
|
|
through the JTAG loader:
|
|
|
|
XMD% connect arm hw
|
|
XMD% source ./ps7_init.tcl
|
|
XMD% ps7_init
|
|
XMD% init_user
|
|
XMD% source ./stub.tcl
|
|
XMD% target 64
|
|
XMD% dow u-boot.elf
|
|
XMD% con
|
|
|
|
7. Insert an SD card with a file called "parallella.bin" on boot partition.
|
|
|
|
8. In the serial port console program enter the following sequence:
|
|
(Note: Takes several minutes, be patient)
|
|
|
|
mmc info
|
|
fatload mmc 0 0x4000000 parallella.bin
|
|
sf probe 0 0 0
|
|
sf erase 0 0x1000000
|
|
sf write 0x4000000 0 0x$filesize
|
|
|
|
9. Power off board and take out the SD card.
|
|
|
|
9. Set the ethernet address
|
|
zynq-uboot> set ethaddr 04 4F 8B 00 00 66
|
|
zynq-uboot> saveenv
|
|
|
|
10. Power down board
|
|
|
|
11. At this point the board is ready for general use.
