DDR3 Connecting issue

Sudheer Ravula

Dear All,

In Dm8168 we are using only one DDR3 controller and other one is not used. In our board we are able to connect JTAG and UART but we are not able to access DDR3. Can we use only one DDR3 controller because In EVM we saw that 2 controllers are used. If we can use can send me how to terminate second controller.

Sedheer,

Yes, you can use only one EMIF. See the below e2e threads for more info.

Do you mean you can not access your custom board from JTAG? Which CCS version you are using? Which JTAG emulator you are using?
