Hi Guys,

 

I am using twr - k70f120m board. The IDE I am using is keil uvision v5.28.0.0. I wanted to test the DDR in the twr board. How do I test it ? Is there any example or document which tells how to write and read from DDR ? I need to know the steps and initialization required to write and read from DDR.

 

In keil for projects there are four options,

I thought if we select the Int Flash DDRData the code will be written to DDR, But DDR is said to be volatile, So on power cycle the code should not run. But it is still running.

 

Can anyone please help me with the concept of the DDR.

 

Regards,

Vibhu.
