The board is getting successfully calibrated with 800MHz and 1200MHz DDR4 clock frequency. I am trying to calibrate it with 2000MHz but while DDR stress test it is failing as data mis-match between read and write.</P><P>I have updated the DDR Stress test tab in the RPA as below:</P><TABLE width="382"><TBODY><TR><TD width="127">memory set</TD><TD width="114">0x30360054</TD><TD width="44">32</TD><TD width="97">0xFA031</TD></TR></TBODY></TABLE><P>&nbsp;</P><P>Still it is not working. Can you please let me know how to resolve this issue?</P> Tue, 12 Jul 2022 11:26:38 GMT https://community.nxp.com/t5/i-MX-Processors/How-to-calibrate-IMX8MP-with-2000MHz-clock-frequency/m-p/1488098#M192430 abhiroopnray 2022-07-12T11:26:38Z https://community.nxp.com/t5/i-MX-Processors/How-to-calibrate-IMX8MP-with-2000MHz-clock-frequency/m-p/1488431#M192452 <P>DDR4 couldn't support 2000Mhz, only lpddr4 does</P> <P>&nbsp;</P> Wed, 13 Jul 2022 03:23:21 GMT https://community.nxp.com/t5/i-MX-Processors/How-to-calibrate-IMX8MP-with-2000MHz-clock-frequency/m-p/1488431#M192452 joanxie 2022-07-13T03:23:21Z https://community.nxp.com/t5/i-MX-Processors/How-to-calibrate-IMX8MP-with-2000MHz-clock-frequency/m-p/1488490#M192457 <P>Hi Joanxie,</P><P>&nbsp;</P><P>I am sorry for the typo, but we are using lpddr4.</P> Wed, 13 Jul 2022 05:52:09 GMT https://community.nxp.com/t5/i-MX-Processors/How-to-calibrate-IMX8MP-with-2000MHz-clock-frequency/m-p/1488490#M192457 abhiroopnray 2022-07-13T05:52:09Z
