The BORA Xpress SOM product is based on the recent Xilinx Zyng XC7Z015/XC7Z030 application processor.
The use of this processor enables extensive system-level differentiation of new applications in many industry fields, where high-perfomance and extremely compact form factor (85mm x 50mm) are key factors. Smarter system designs are made possible, following the trends in functionalities and interfaces of the new, state-of-the-art embedded products.
The Zynq™-7000 family is based on the Xilinx Extensible Processing Platform (EPP) architecture. These products integrate a feature-rich dual-core ARM® Cortex™-A9 based processing system (PS) and 28 nm Xilinx programmable logic (PL) in a single device. The ARM Cortex-A9 CPUs are the heart of the PS and also include on-chip memory, external memory interfaces, and a rich set of peripheral connectivity interfaces. The Zynq-7000 family offers the flexibility and scalability of an FPGA, while providing performance, power, and ease of use typically associated with ASIC and ASSPs. The range of devices in the Zynq-7000 AP SoC family enables designers to target cost-sensitive as well as high-performance applications from a single platform using industry-standard tools. While each device in the Zynq-7000 family contains the same PS, the PL and I/O resources vary between the devices. As a result, the Zynq-7000 AP SoC devices are able to serve a wide range of applications including:
The processors in the PS always boot first, allowing a software centric approach for PL system boot and PL configuration. The PL can be configured as part of the boot process or configured at some point in the future. Additionally, the PL can be completely reconfigured or used with partial, dynamic reconfiguration (PR). PR allows configuration of a portion of the PL. This enables optional design changes such as updating coefficients or time-multiplexing of the PL resources by swapping in new algorithms as needed.
BORA Xpress can mount two versions of the Zynq processor. On this page you can find a table that shows a comparison between the processor models, highlighting the differences.

The boot process begins at Power On Reset (POR) where the hardware reset logic forces the ARM core to begin execution starting from the on-chip boot ROM. The boot process is multi-stage and minimally includes the Boot ROM and the first-stage boot loader (FSBL).
The Zynq-7000 AP SoC includes a factory-programmed Boot ROM that is not useraccessible.
The boot ROM:
After a system reset, the system automatically sequences to initialize the system and process the first stage boot loader from the selected external boot device. The process enables the user to configure the AP SoC platform as needed, including the PS and the PL. Optionally, the JTAG interface can be enabled to give the design engineer access to the PS and the PL for test and debug purposes.

Yes. ConfigID is a new feature of DAVE Embedded Systems products. Its main purpose is providing an automatic mechanism for the identification of the product model and configuration.
With ConfigID, we aim at completing the hardware configuration information that the software can't normally auto-detect (i.e. RAM chip version,...), implementing a dedicated reliable detect procedure and, when required, overriding the auto-detected hardware configuration information.
An additional attribute is UniqueID, which is a read-only code which univocally identifies a single product and is used for traceability.
For further information, see this page.
BXELK (software development kit for BORA Xpress) introduce introduce some significant differences with respect to the previous versions. The characterizing items are:
The typical Linux-based Zynq design is composed of the following parts:
For further information, see this page.
It is assumed that the development environment has been set up properly as described here.
Assuming that:
the system can boot using the net_nfs[a] configuration, as described here.
[a] The net_nfs configuration, besides setting the system for booting from the network, triggers a command (program_fpga) which loads the FPGA binary from TFTP and programs the bitstream.
The software development environment for Processing Subsystem (PS) is quite complex because it is based on several tools. This page collects the resources, available in this wiki, which are related to these tools, in order to illustrate how to install and set up them.
Here you can find an introduction to development environment.
A build system is a set of tools, source trees, Makefiles, patches, configuration files and scripts that make it easy to generate all the components of a complete embedded Linux system. A build system, once properly set up, automates the configuration and cross-compilation processes, generating all the required targets (userspace packages such as libraries and programs, the o.s. kernel, the bootloader and root filesystem images) depending on the configuration. In particular, using an integrated build system prevents from problems caused by misaligned toolchains, since a unique toolchain is used to build all the software components, including the customer application.
On this page you can find an in-depth explanation about how to generate all the components of a complete embedded Linux system. We will refer to the system running the Xilinx tools (that can be either a Microsoft Windows machine or a GNU/Linux machine) as the "Zynq development server", and to the machine running the GNU/Linux tools as the "Linux development server".
As described here, the structure of the BELK/BXELK has changed over the years. That's why the instructions indicated may differ according to the kit version.
See this page for further information on how to keep the source trees in sync and up to date with DAVE Embedded Systems’ git repositories.
See this page for further information on how to build the U-Boot bootloader on BXELK.

See this page for in-depth information on how to build the project.
BXELK provides one (or more) pre-built root file system, that can be used during the evaluation/development/deployment cycle. To generate the supported root file systems, the build of the Yocto BSP has to be run.
See this page for in-depth information on how to build the Yocto BSP (initializing the build environment, running the build, generating the SDKs and building additional packages).
BXELK provides a bootable microSD that can be used not only to quickly start the system, but also as a recovery method in case the primary boot device (eg. QSPI NOR flash) gets erased or corrupted.
This page describes how to create a bootable SD card and how to configure the system for booting from SD.
This page describes how to restore U-Boot on SPI NOR flash in case it gets corrupted or it is deleted accidentally.
On this page you can find how to configure Bora/BoraX/BoraLite for standalone operativity.
The page explains how to program and configure a BORA Xpress-based system to boot in standalone mode, without the need of a system microSD card or an NFS server. Only the flash memories available on the SoM itself will be used to store persistently all the software required.
For deploying an Embedded System, one of the most important configuration is the Network Interface configuration.
Once the Embedded Device is finally configured for stand-alone bootstrap, the network interface should be configured for reaching the device remotely via network connections like ssh, telnet, ftp, http, etc.
This page explains how to simply configure the network interfaces on SystemV or systemd.
