The boot.bin file is board specific and contains the MAC address for the ethernet, so you need a unique one for each type of board you use on a network. If you only have one board, you can use prebuilt images from the versioned branch of zynq-boot-filesystems:

• https://github.com/cambridgehackers/zynq-boot-filesystems/tree/v15.08.1

From that link, download:

• https://github.com/cambridgehackers/zynq-boot-filesystems/blob/v15.08.1/sdcard-zynq.zip

also download a bootbin*.zip for your board:

• zedboard: https://github.com/cambridgehackers/zynq-boot-filesystems/blob/v15.08.1/bootbin-zedboard-00e00c009603.zip
• zc702: https://github.com/cambridgehackers/zynq-boot-filesystems/blob/v15.08.1/bootbin-zc702-00e00c005603.zip
• zc706: https://github.com/cambridgehackers/zynq-boot-filesystems/blob/v15.08.1/bootbin-zc706-00e00c004f03.zip

My SD card is labeled "ZYNQ" and under Ubuntu mounts as /media/jamey/ZYNQ. On OS X it mounts as /Volumes/ZYNQ. Update the following with the path to your SD card:

unzip sdcard-zynq.zip cp sdcard-zynq/* /media/jamey/ZYNQ unzip bootbin*.zip cp bootbin03/ /media/jamey/ZYNQ

Now eject your SD card, plug it into the Zynq board, and turn it on.

Scripts to create a boot.bin file for linux on Xilinx Zync

The boot.bin file contains 4 components:

1. First Stage Boot Loader (fsbl).

This file does limited initialization of the ARM processor and also initializes the DRAM controller, giving access to RAM. Note that the attached DRAM is different between zedboard/zc702. This is a binary file imported from a Xilinx tool release. If you wish to build a new one for some reason, directions are at:

• http://www.wiki.xilinx.com/Build+FSBL

(you need to use the Xilinx IDE to create a project and then use their Codesourcery gcc toolchain to compile).

2. zImage.

This is the linux kernel, compiled from:

• github.com:cambridgehackers/linux-xlnx.git

3. ramdisk.

This is created from the files in the 'data/' directory of this git repo.

4. devicetree.dtb.

This is the devicetree specification of peripherial addresses, to avoid wiring them down in the source code of the device driver. (Needed since most peripherials are not discoverable through runtime probing). Note that the peripherials are different between the zedboard and the zc702 board.

The boot.bin is board-specific, because the first stage boot loader (fsbl) and the devicetree are both board-specific.

To see all possible make targets, please just type:

make

To build a everything for a zedboard:

make all.zedboard

To build just a boot.bin for a zedboard:

make bootbin.zedboard

To build a everything for a zc702:

make all.zc702

To build a everything for a zc706:

make all.zc706

If you would like to use a different kernel, you can make it from source.

# step 1: get the linux kernel source
git clone git@github.com:cambridgehackers/linux-xlnx.git

# step 2:
cd linux-xlnx/

# step 3: check out the xbsv-2014.04 branch
git checkout remotes/origin/xbsv-2014.04 -b xbsv-2014.04

# step 4: configure the kernel. We use CodeSourcery 2009q1. The NDK toolchain does not work for this.
make ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabi- xilinx_zynq_portal_defconfig  

# step 5: make the kernel
make ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabi-   

# step 6: copy the new kernel into zynq-boot
cp arch/arm/boot/zImage ../zynq-boot/imagefiles/zImage  

Compiling the xbsv device drivers on linux:

1. clone linux-xlnx.git

2. clone cambridgehackers/mac_linux_headers.git

3. use mac_linux_headers/compile.sh for running 'make' on linux-xlnx

(this will create a usable dts executable for creating boot.bin from this repo)

The devicetree compiler source code is part of the Linux kernel source code. Here is how to build the devicetree compiler without building the entire kernel:

git clone https://github.com/cambridgehackers/linux-xlnx.git
cd linux-xlnx/
git checkout origin/xbsv-2014.04 -b xbsv-2014.04
make ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabi- xilinx_zynq_portal_defconfig
make ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabi- M=scripts/dtc

Even though the build complains about a missing arm-none-linux-gnueabi-gcc, it still builds the executable scripts/dtc/dtc correctly.

Support has been added for the Avnet 7Z100 Mini-ITX development kit:

http://www.zedboard.org/product/mini-itx

The ethernet MAC address is derived from your $(USER) name.
To make boot.bin files for multiple devices that are attached to the network at the same time:

make bootbin.zedboard USER=uniquetringforboard

The webserver in zynq-boot/imagefiles/webserver is from the webui repo. It provides a websocket server so that a browser can communicate with the zedboard to download and run applications.

https://github.com/cambridgehackers/webui/blob/master/src/zedboard-server.c

You can build it using ndk-build:

git clone git://github.com/cambridgehackers/webui
cd webui
ndk-build

There is a target to build it in zynq-boot: cd zynq-boot; make webserver

To add a new board:

1) Add the boardname to Makefile

2) add zynq-<boardname>-portal.dts zynq_<boardname>_fsbl.elf to imagefiles/

3) make sure that bootargs in the dts file is updated to reflect the boot ramdisk and /dev/fpgaXXX devices

 1) touch data/init.debug  (create the empty file init.debug in the zynq-boot/data directory)
 2) make bootbin.xxx       (where xxx is your target machine, e.g., zedboard)

This creates a file /init.debug on the target device. When the Android system/core/init/init.c command runs, if this file exists stdio devices are not closed.
