UnboxingEdit

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

• building the first-stage bootloader:
  • FSBL for BELK 3.0.2 or older
  • U-boot SPL for BELK 4.0.0 or newer
• building the second-stage bootloader (U-Boot)
• building and running Linux operating system on Bora-based systems
• building Linux applications that will run on the target.

DAVE Embedded Systems provides all the customization required (in particular at bootloader and Linux kernel levels) to enable customers to use the standard Zynq-7000 development tools for building all the firmware/software components that will run on the target system.
