Unboxing[edit | edit source]


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 BORA Xpress 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 BORA Xpress SOM and BORA Xpress Evalutation kit
  • source code of target software
  • technical documentation (hardware manuals, mechanical drawings, reference schematics, application notes etc.)

  • 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 BORA Xpress 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.
