Hi Jinlong

for custom board it may be necessary to port (change) SCU Firmware binaries:

“mx8qx_scfw_download.bin” as described in sect.2.2.1 MX8QM/QX SCU Firmware Requirement

MX8_DDR_Tool_User_Guide.pdf, use SCFW Porting Kit

and instructions provided in MX8X_DDR_Tools_quickstart_guide.pdf

Best regards
igor

We will be the latest SCFW source code ------imx-scfw-porting-kit-1.2 next week, and compile and replace the bin sdm file mx8qxb0_scfw_download.bin under the Stress DDR test tool, but click on the download will cause the above problem (card live)

this part is not fully supported and it is "PREPRODUCTION" state as shown below

i.MX 8X Applications Processors| Arm® Cortex®-A35, Cortex-M4 | NXP

so may be suggested to proceed with help of NXP Professional Services | NXP

I have a custom imx8qxp board. I want to do DDR stress test. I am not finding the DDR test tool for imx8qxp. Can I have the download link for the stress tool.

Hello Igor,
Could you please provide a download link for the "MX8X_DDR_Tools_quickstart_guide.pdf" mentioned earlier?
Also, could you possibly clarify what type of stress tool is meant to be used for the iMX8QXP? The stress tool I can find seems related to the iMX8QM series. Could this also possibly be used for the iMX8QXP? mscale_ddr_tool_v310_setup.exe.zip

Thanks
