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.
BORA Xpress is designed in order to keep full compatibility with theULTRA Line CPU modules, to guarantee the premium quality and technical value of those customers that require top performances.

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. This page provides useful information and resources to system designers in order to design carrier boards hosting DAVE Embedded Systems system-on-modules (SOM).
These guidelines are provided with the goal to help designers to design compliant systems with DAVE Embedded Systems modules and they cover schematics and PCB aspects.
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. In simple words, model identification means the capability of reading a numerical code, stored in an available device (SOC's OTP , I2C EEPROM, 1-wire memories, protected NOR flash, etc.)
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 more information about DESK-XZ7-L (Software Development Kit for BORA Xpress SOM) ConfigID and UniqueID, see this page.
On this page you can find the links for the BORA Xpress Evaluation Kit schematics and the related documents (BOM and layout).
On this page you can find the mechanical characteristics of the BORA Xpress Evaluation Kit.
BORA family uses the first 32bytes OTP block on NOR SPI to store ConfigID (and its CRC32), UniqueID (and its CRC32). U-Boot integrates the software routines for reading and displaying the ConfigID.
Generally speaking, SOM ConfigID is used to identify the configuration of the basic features of the SOM and CB ConfigID is used to identify the peripherals and the I/O interfaces.
Please visit this page for more detailed information.
Yes, you can. This configuration is very helpful during software development (both for kernel and applications). The kernel image is downloaded via TFTP while the root file system is remotely mounted via NFS from the host. It is assumed that the development host:
is connected with the target host board through an ethernet LAN
exports the directory containing the root file system for the target through the NFS server
runs a TFTP server
has a proper subnet IP address
DESK-XZ7-L Virtual Machine is properly configured for the TFTP and NFS debug.
In any case, some variables have to be configured on the target and the VM itself has to be configured with respect to the network environment.
Please visit this page for more detailed information about the Virtual Machine and target configuration or the booting via NFS with PXE protocol and Petalinux.
In DESK-XZ7-L (Software Development Kit per BORA Xpress SOM) there are two main repositories to:
track and reproduce hardware design with Vivado
track and reproduce Petalinux/Yocto build
Additional repositories will be used to track other piece of software that requires customization (e.g. U-Boot bootloader, Linux kernel, sample application and so on)
Access to DAVE Embedded Systems' git repositories is granted to the development kit's owners only. Please refer to our video tutorial How to access DAVE Embedded Systems' git repositories for detailed instructions on how to get access.
