Operating Systems Design and Implementation Stanford Winter 2019. So long as your board design is such that the boot pins needed and the interface is left available this option is always there, but the moving of the data to be programmed is done by an external master, the actual programming of the flash from that data is done by the bootloader. Experimental results show that the Bootloader boots the application accurately and implements application’s downloading and upgrading exactly and easily. The current design is based on a specialized kernel called the "prekern", which operates between the bootloader and the kernel itself.
