U-Boot – Bootloader for IoT Platform? – Alexey Brodkin, Synopsys
Typical IoT devices have a limited amount of memory: both ROM and RAM sizes are usually measured in kilobytes as opposed to megabytes on Linux boxes.
This presentation demonstrates how to squeeze U-Boot with required functionality into a board with 256kB or less of ROM and RAM.
We’ll start from an overview of U-Boot features that could be useful on IoT device and then we’ll see what could be done to reduce U-Boot memory footprint with existing configuration options, which changes to generic or platform code might be done to shave off more extra space and finally how can we keep all the code in ROM preserving precious RAM for a payload.
