Unboxing

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 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.)
