Hello,

Software/ Hardware details,

L4.14.98 + IMX8QM Custom Board

SCFW 1.2.1

RPA: V17

I got the following response from DDR Stress Test,

If you want to watch DDR script executing process, please open SCU debug uart in other serial tool

Waiting for the target board boot...

Hi Vinothkumar

reason for that behaviour may wrongly configured uart, one can look at below link  "FAQs:"

https://community.nxp.com/t5/i-MX-Processors-Knowledge-Base/i-MX-8-8X-Family-DDR-Tools-Release/ta-p/...

Also recommended to attach another terminal to " SCU debug uart" as suggests ddr test log.

Best regards

Thank you @igorpadykov for the reply.

<Vinoth> Currently there is one debug UART in custom board. Is it enough to do the DDR Stress Test ?

[igorpadykov]

for " SCU debug uart" please refer to documentation included in  SCFW Porting Kit​

I got the following log from DDR Stress Test Tool. But, the hardware is limited to one debug uart (UART1).

Is it possible to enable/route all message through one debug UART ?.

Will you please provide the SCFW board configuration file (with modified debug uart) for UART1 for SCU UART.

or Do I needs to do any hardware modification ?
