BoraX Embedded Linux Kit (BXELK)

Info Box Applies to BORA Xpress

For BXELK 1.0.1 or older, the boot process was based on the FSBL+second-stage bootloader (U-Boot) combination. From BXELK 2.0.0 on, the boot process is based on the first-stage bootloader (U-Boot SPL)+second-stage bootloader (U-Boot) combination.

Introduction

BoraX SOM

BoraX Embedded Linux Kit (BXELK for short) provides all the necessary components required to set up the developing environment for:

• building the first-stage bootloader:
  • FSBL for BXELK 1.0.1 or older
  • U-boot SPL for BXELK 2.0.0 or newer
• building the second-stage bootloader (U-Boot)
• building and running Linux operating system on BoraX system-on-module (SOM)
• building and debugging applications that will be executed on top of Yocto-based Linux distribution running on the target.

The main kit components are:

• hardware platform, composed by BoraX SOM and BoraXEVB
• source code of target software
• technical documentation (hardware manuals, mechanical drawings, reference schematics, application notes etc.)

Kit content

Component	Description	Notes
	BoraX SOM (p/n DBXF4110D2R) SoC: Xilinx XC7Z030 (866Mhz, Speed "-3", Tj 0-100°C) SDRAM: 1 GB DDR3 NOR: bootable SPI flash 16 MB NAND: 1GB (SLC)	For more details, please refer to the BoraX Hardware Manual By default, ARM cores frequency is set to 667 MHz and the example Vivado project is implemented for a "-1" device. This choice makes the software released with the kit compatible with possible variants based on different SoM models. In this regard, see also the order codes section.
