Abstract
The development port or Debug port of a microprocessor on an intelligent daughterboard is used for downloading code or configuration information from a motherboard for use in boot-up. In various aspects, the code or configuration information can include information used for configuring a port, other than the development port, and/or for configuring a memory controller, such as for a daughterboard DRAM. Use of the Debug port makes it possible to reduce or eliminate the need for storing boot-up code or configuration information on a daughterboard ROM, or other non-volatile memory, thus reducing cost and space requirements, power consumption and the like.
