Our custom board MLO can't boot correct , hang in first stage.

I know maybe is hardware issue , but i don't have any idea to check what happen.

Hi,

Have you tuned your DDR memory? Here are the relevant links:

Thanks for your reply

I have tested DDR memory below is the result what I examined.

Enter the PHY_INVERT_CLKOUT value (0 or 1) from the spreadsheet
0

Enter the Seed RD_DQS_SLAVE_RATIO Value in Hex to search the RD DQS Ratio Window
40

Enter the Seed FIFO_WE_SLAVE_RATIO Value in Hex to search the RD DQS Gate Window
70

Enter the Seed WR_DQS_SLAVE_RATIO Write DQS Ratio Value in Hex to search the Write DQS Ratio Window
01

I don't know what type of memory you are using, so I cannot comment. You should also fill in the timing spreadsheet and adjust the timing registers appropriately. Just follow the step-by-step guide that I posted above.
