The BORA Lite SOM product is the updated version of BORA SOM and it is based on the Xilinx Zynq XC7Z007S/XC7Z014S or XC7Z010/XC7Z020 application processor. BORA Lite is compact solution that includes both a CPU and an FPGA, avoiding complexities on the carrier PCB and thanks to SODIMM form factor is the cheapest solution to integrate a Zynq SOC in an embedded design.

The Zynq™-7000 family is based on the Xilinx Extensible Processing Platform (EPP) architecture. These products integrate a feature-rich single/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.

Implementing correct power-up sequence for Zynq-based system is not a trivial task because several power rails are involved. BORA Lite SOM simplifies this task by embedding all the needed circuitry. Here you can find a simplified block diagram of PSU/voltage monitoring circuitry.

The recommended power-up sequence is:

1. main power supply rail (3.3VIN) ramps up
2. carrier board circuitry raises CB_PWR_GOOD; this indicates 3.3VIN rail is stable (1)
3. Bora's PSU enables and sequences DC/DC regulators to turn circuitry on
4. BOARD_PGOOD signal is raised; this active-high signal indicates that SoM's I/O is powered. This signal can be used to manage carrier board power up sequence in order to prevent back powering (from SoM to carrier board or vice versa).

For further information, see this page.

Here you can find information about the Programmable Logic (PL) initialization signals: PROGRAM_B, INIT_B, and DONE.

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:

• determines whether the boot is secure or non-secure
• performs some initialization of the system and cleanups
• reads the mode pins to determine the primary boot device
• once it is satisfied, it executes the FSBL

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.

JTAG signals are routed to a dedicated connector (J2) on the BORA Lite PCB. The connector is placed on the top side of the PCB, at the upper-right corner.
Here you can find the table that reports the connector’s pinout.

For further information on how to use the JTAG interface, please contact the Technical Support Team.

Here you can find Axel ULite SOM’s maximum ratings, recommended ratings and power consumption.

Providing maximum power consumption of a system-on-module (SOM for short) is virtually impossible because it is extremely hard to define the worst case. This is even more true in case of BORA Lite, where this is affected by the software running on Processing System (PS) side and the Programmable Logic (PL) configuration.

For this reason, several real use cases have been considered rather than indicating a theoretical maximum power consumption value that would be useless for the majority of system integrators, because it likely would lead to an oversized power supply unit.

Here we describe in detail the testbeds that have been used.
