Description

This command is provided to define a user-defined external memory device, outside the hardware system. Such a device would typically be mapped through a bridge component. This command adds an external memory device to the BSP's memory map, allowing the BSP to define memory regions and section mappings for the memory as if it were part of the system. The external memory device parameters are stored in the BSP settings file.
