IMX8MM DDR Stress Tool test stuck

crcn — Mon, 06 Feb 2023 14:40:54 GMT

Hello.

I have a custom imx8mm board with a 512MB DDR4 (K4A4G165WE-BCTD).

I want to do the DDR stress test (following the User guide). For that, I configured the DDR4 parameters in the MX8M_Mini_DDR4_RPA_v20.xls

I did the calibration with these parameters in the Mscale DDR Tool:

But whhen I tried to do the Stress Test, it stuck's here:

Can you help me? What I'm doing wrong?

Thanks.

Could you share us the DDR datasheet to us?

Your configuration is right, how about your status in your side?

Did someone find a solution to this behaviour? I got the same problem, but with LPDDR4 and with the imx8-config tool? @Rita_Wang
