Currently, 50 boards have been produced. 45 boards can be burned and written. 5 boards cannot be burned and written. When using a memory testing tool to calibrate a board that cannot be burned, the following error appears in the attachment. May I ask which part of the error this error is and how to resolve it. In addition, when running 5 chips to uboot, the following errors often occur。</P><P>&nbsp;</P> Mon, 26 Jun 2023 05:48:14 GMT https://community.nxp.com/t5/i-MX-Processors/MX8MP-DDR-Training-Tool/m-p/1675623#M208110 vachlan 2023-06-26T05:48:14Z https://community.nxp.com/t5/i-MX-Processors/MX8MP-DDR-Training-Tool/m-p/1676524#M208182 <P>Hello&nbsp;<a href="https://community.nxp.com/t5/user/viewprofilepage/user-id/145768">@vachlan</a>&nbsp;</P> <P>Please provide your RPA file, <SPAN>&nbsp;calibrate log and uboot log file .</SPAN></P> Tue, 27 Jun 2023 02:50:01 GMT https://community.nxp.com/t5/i-MX-Processors/MX8MP-DDR-Training-Tool/m-p/1676524#M208182 Zhiming_Liu 2023-06-27T02:50:01Z
