Meaning
Legal permissions governing the use and modification of the software layer that links an operating system to specific silicon. This board support package licensing usually involves a bundle of drivers, bootloaders, firmware and configuration files provided by a chip manufacturer to an original equipment manufacturer. The license defines whether the code is for internal development only or if it can be redistributed in commercial hardware products.
It sets the boundary between proprietary vendor code and the open source kernel.
System Architecture
Hardware vendors provide these software blocks to ensure that high level operating systems can communicate with specific registers and peripherals on a custom circuit board. Because board support package licensing often carries restrictions on reverse engineering, the purchaser must verify that the provided binaries do not prevent security audits. Access to source code remains a point of negotiation during the procurement of system on chip components.
Commercial Restriction
Software rights in this domain frequently limit the use of the drivers to a specific serial number or processor model. A company using board support package licensing must ensure the terms allow for the sale of the business and the transfer of software rights to an acquirer. Failure to secure these rights can block a company exit or necessitate expensive royalty renegotiations that jeopardize the deal value.
This risk is most acute when the hardware depends on proprietary silicon from a single source vendor.
Quality Standard
Testing the stability of the software bundle is required before the hardware reaches volume production to ensure that no memory leaks or driver conflicts disrupt the user experience. Performance depends on the board support package licensing.
