BORA Lite SOM/BORA Lite Evaluation Kit/pdf

Getting started

Kit Identification Codes

The development kits (DESK, XELK, XUELK, BELK, etc.) are identified by a couple of codes:

1. P/N Part Number identification code
2. S/N Serial Number identification code

These codes are printed on a label sticked to the box containing the kit.

For example, the following picture shows such a label of an AXEL Ultra XELK (XELK-H-S) with Serial Number 0CFA

Label of AXEL Ultra XELK (XELK-H-S)

These codes are required to complete the registration process of the kit.

Unboxing

Once you've received the kit, please open the box and check the kit contents with the packing list included in the box, using the table on this chapter as a reference.

The hardware components (SOM, carrier boards and display) are pre-assembled, as shown in the picture below:

microSD Layout

The microSD provided with the kit is used to store:

• a bootable partition (mmcblk0p1, vfat) containing:
  • binary images (u-boot and kernel images)
• root file system partition (mmcblk0p2, ext4)

Target setup and first boot

This section describes how to quickly start Bora/BoraEVB and BoraX/BoraXEVB systems included in the BELK/BXELK:

• on target side, connect a null-modem cable on J17 DB9 connector, denoted also as UART1
• on host side, connect the other end of the null-modem cable to a COM port and start your favorite terminal software that will be used to interact with the target's serial console; communication parameters are 115200-8-N-1
• optionally connect the BoraEVB/BoraXEVB board to an Ethernet LAN by plugging cable into connector J8, also denoted as ETH0 on BoraEVB and BORAX ETHERNET on BoraXEVB
• connect 12V power supply to JP2 or J7 connector, also denoted as PSU 12V
• insert the microSD card in the slot J21, also denoted as MICROSD.

Once power has been applied to the target, FSBL or U-boot SPL and U-Boot bootloaders will be fetched from the SPI NOR flash that equips Bora/BoraX/BORA Lite SOM and executed. Boot messages will be printed out to the serial console. Redundant U-Boot environment is stored in the NOR flash as well, as depicted in the following image.

NOR flash default partitioning (BELK 3.0.2 or older and BXELK 1.0.1 or older)

NOR flash default partitioning (BELK 4.0.0 or newer and BXELK 2.0.0 or newer)

By default, U-Boot is configured to retrieve Linux kernel image stored in the microSD card [1]. In turn, Linux kernel shall mount root file system from the mmcblk0p2 partition of the microSD card itself [2], [3]. At the end of boot process, Linux shell shall be available on the serial console. Default boot process does not download any bitstream to the Programmable Logic.

The following dump shows the typical messages printed out to the console during bootstrap process. This log refers to Belk-4.0.0 running on BORA SOM. For BORAX SOM similar messages are printed out to the console.

bora login:

[1] bootscript is used to do this task.

[2] This root file system has been generated by Yocto build system.

[3] The microSD card is bootable itself, as explained here.

microSD layout

The microSD card provided with BELK/BXELK is partitioned as shown in the following image:

microSD card partitioning

Most of storage space is occupied by two partitions:

• a FAT32 partition (mmcblk0p1) containing:
  • For BELK <= 3.0.2 and BXELK <= 1.0.1 :
    • boot.bin boot image (containing FSBL, FPGA Bitstream an U-boot binaries)
    • U-Boot boot.scr bootscript
    • Linux kernel and DTB binary images
  • For BELK 4.0.0 or newer and BXELK 2.0.0 or newer:
    • boot.bin u-boot SPL image
    • fpga.bit optional FPGA bitstream
    • u-boot.img u-boot image
    • U-Boot boot.scr bootscript
    • Linux kernel and DTB binary images
    • MVM image in OVA format
• an ext3 partition (mmcblk0p2) containing the root file system for the target.

bootscript and root file system are used to boot the target as described in this section.

It is worth remembering that the microSD card is bootable and U-Boot environment is retrieved from (and stored to with saveenv) into the FAT partition as bora.env

Boot mode selection - S5

S5 is a dip-switch for the boot mode selection. The following table reports the available options and the related configurations:

	S5.1	S5.2	S5.3	S5.4	S5.5	S5.6	S5.7	S5.8
SPI-NOR	OFF	ON	OFF	ON	ON	ON	ON	OFF
SD-card	OFF	ON	OFF	ON	ON	OFF	ON	OFF
NAND (*)	OFF	ON	OFF	ON	ON	OFF	ON	ON
JTAG	OFF	ON	OFF	ON	ON	ON	ON	ON

(*) Boot mode from NAND in supported ONLY on BORA Lite SOM module

Reset button - S6

S6 is the hardware reset button connected to the MRSTn signal (J2.16 SOM connector)

Power supply - JP2

Power is provided through the JP2 connector.

JP2 connector is a standard 2.1mm/5.5mm DC power jack with positive center pin

SoM's signals mapping

Bora Lite

As known, Bora Lite requires an adapter to be mounted on the BoraXEVB carrier board. The adapter swap some signals to allow to use some carrier board peripherals routed on unavailable pins of the SoM. For this reason, it can be tricky to find out where the SoM's signals are routed at the carrier board level. The following table details such routing for PL banks. Here it is assumed to use an adapter with default mounting options.

JTAG

JTAG

JTAG port is available as two different mechanical connectors:

• 2.00mm-pitch 7x2 header (Xilinx standard)
• 2.54mm-pitch 10x2 header (ARM standard): http://www2.lauterbach.com/pdf/arm_app_jtag.pdf
• This port is connected to Zynq's native JTAG signals. Please note that Zynq's internal JTAG chain supports differents configurations, depending on bootstrap signals. In case split mode is selected, CPU JTAG can be routed separately via PL. For more details please refer to Zynq Technical Reference Manual.
• JTAG on BORA Xpress EVB is also connected to the FMC connector. For more details on how to connect JTAG on a custom FMC card please refer to ANSI/VITA FPGA Mezzanine Card (FMC) Standard.
