i.MX 8M Family DDR Tool Hangs on Waiting for the target board boot

[onurcalili]

Hello everyone,

We have designed a custom board with i.MX 8M Quad CPU. We controlled the voltages and clocks on the board. But when we try DDR Tool, it prints the logs given below Tool does not print anything after "Waiting for the target board boot...". We stuck at this point. What can we try after this point? Any help appreciated.

Hi Igor, 

Thanks for advice. The problem was in our design. We have an usb to uart converter in our board and its rx tx lines are not crossed on the board. When we corrected the rx and tx lines now i can see the output on DDR Tool.

Best regards

Hi Onur

one can check uart, if it is different from reference board add configuration

in script (MX 8M Family DDR Tool link provides examples).
