Let's have the discussion here about the issues to bring up Vybrid with the DDR3 memory.

Current open questions are:

-Can you test what tests pass during a cold boot? What is the general behavior during a cold boot of the memory data (while running on iram)

-Can you test how stable is data during a cold boot? (is all dead? Like zeroes? Or you data is partially stable where some writes and reads pass and others not, you can open the memory location ax 0x80000000 to take a look) -Can you test if at cold boot lower frequencies pass?

-Can you test if at cold boot lower frequencies pass?

The DDR Stress Test will need some updates based on the memory you are using and the working configuration you have.

-Another thing I am wondering if if this cold boot issue is related to the memory controller or some wait times required to the memory to stabilize after a reset?
