TI experts-
We need to run 64-bit vs. 32-bit DDR3 mem tests on the 8681 (quad C6678) PCIe card. The card has 64-bit DDR3 mem installed (4x 16-bit devices). Our question: is it do-able and if so what is the best way to configure the card for 32-bit mem width (i.e. not use 1/2 the memory) ?
If we set the narrowMode bits in DDR3Init(), rebuild platform lib, and then download and run init.out normally, before any application code runs, will that work? What other registers have to be changed? If so, what is a good way to know that our change is "sticking" ?
