I worked that out by using the eCos-1.3.1 distribution (adding vrc4375 package) to build a working stub and then using the CVS tree for applicition library building. I didn't changed much from vrc4373, but since I can not get PMON source code from NEC after several times asking, I have to find out the differences from 4375's datasheet. The major difference is the SDRAM power-up sequence. Regards, -Ling
