Simplifying Zynq Boot
Creating a Zynq boot.bin has been a source of headaches for quite some time. It requires a toolchain different from the one in NDK build and also seems to have some dependences on variations of other common Unix tools.
The only reason anyone has to build a boot.bin themselves is because it contains the MAC address for the ethernet. On the zedboard, at least, there is not a better place to store it. Zybo does have an eeprom for this purpose, but we do not have that working yet.
I’m working on a web-hosted development environment, and as part of that took a step towards packaging zynq-boot in an easier to use way.
I packaged the stable, board-independent pieces into sdcard-zynq.zip and the faster changing or board-dependent components into bootbin-$(BOARD)-$(MACADDR).zip. If you only have one board of a particular type, you can use a prebuilt bootbin.zip. Otherwise, you’ll still need to be able to build boot.bin or to use the web-hosted boot.bin creation service when it’s available.
The current prebuilt images for zedboard, zc702, and zc706 are here:

From that link, download:
- https://github.com/cambridgehackers/zynq-boot-filesystems/blob/v15.02.1/sdcard-zynq.zip
also download a bootbin*.zip for your board:
- zedboard: https://github.com/cambridgehackers/zynq-boot-filesystems/blob/v15.02.1/bootbin-zedboard-00e00c009603.zip
- zc702: https://github.com/cambridgehackers/zynq-boot-filesystems/blob/v15.02.1/bootbin-zc702-00e00c005603.zip
- zc706: https://github.com/cambridgehackers/zynq-boot-filesystems/blob/v15.02.1/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.
