Typical firmware components

Before diving into firmware, it is essential to understand what the BCM63381B0 is. Broadcom is a dominant force in the xDSL and cable modem market. The BCM63381 is part of Broadcom’s BCM6338 family – a highly integrated, single-chip ADSL2+ residential gateway solution.

The Broadcom BCM63381B0 is an ARM-based SoC designed for entry-level DSL residential gateways, supporting VDSL2, G.vector, and Fast Ethernet. While proprietary SDK components hinder access to full source code, open-source alternatives like OpenWrt provide partial support for the chipset.
