LPC2478-STK SDRAM one or two chip support
« on: July 19, 2010, 02:53:52 AM »
Mark-

In the utasker1.4LCD.pdf you mention that one or both SDRAM chips may be installed on the LPC2478-STK.  Does the code use both chips or only one?

One chip is used for D0-15 and the other for D16-D31.

Hi Kevin

The SDRAM configuration (fnInit_SDRAM()) configures to use just one RAM device on D0..D15. I suspect that th boards are generalyl supplied with just one SDRAM chip soldered.
