BoraX Embedded Linux Kit (BXELK for short) provides all the necessary components required to set up the developing environment to:
* build the first-stage bootloader (FSBL)for BELK <= 3.0.2 and BXELK <= 1.0.1* build U-boot SPL for BELK-4.0.0 and BXELK-2.0.0
* build the 2nd-stage bootloader (U-Boot)
* build and run Linux operating system on [[:Category:BoraX|BoraX system-on-module (SOM)]]
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 BoraX 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.
