DDR Tool UART Usage

simonlocke — Thu, 24 Jan 2019 14:47:44 GMT

I found the latest DDR Tool very helpful: https://community.nxp.com/docs/DOC-340179

I am preparing for the arrival of a custom board and I have been reading the MSCALE DDR Tool User Guide V1.1 document. In there I note the statement to "reserve UART1" for use by the DDR tool code.

On our board, we have not connected UART1 but UART2 for debug.

I'm OK making the necessary changes to the uBoot src itself, but I'm trying to figure out what my options are for getting DDR tool going.

Is is possible to get the a different version of the DDR test binaries? Can we get the src for the DDR test binaries, so I can rebuild it with a different UART? Is there some other way to switch it over? Any suggestions?

Hello,

The mentioned DDR tool does not initialize UART directly. It uses UART,

that already is initialized by the (DDR) script. Examples how to do it

are provided in https://community.nxp.com/docs/DOC-340179

In this sense tool sources codes are not needed (and are not provided).

Have a great day,
Yuri

Hi Yuri,

Thanks for getting your colleague Oliver Chen to update the page (I note that DOC-340179 has been updated over-night).

Looks like I now have the info I need.

Thanks
