A number of the community members are paid members of XMOS staff, while many others are simply excellent volunteers who are interested in building quality stuff. Obviously if these kinds of CPUs was still common SDR SDRAM might have been designed differently, but then DRAM is more complex than SRAM. After power-up an SDRAM, the device must be initialized in a predefined manner. This allows, for example, the same software image to be used across multiple builds of a board, each using a different SDRAM chip and/or boot memory configuration; the SDRAM chip and/or boot memory selection, and strap selection would be altered in tandem during the board manufacturing process to select the appropriate data set within the BCT.
