i mx8 [DDR4] draining failed /using nxp config tool

Hello Community,

we are facing the issue with DDR4 failed while draining process. This is related with i.MX8[MIMX8ML8DVNKZAB] processor with micron memory LPDDR4 [MT53E512M32D1ZW-046BIT:B] While doing functional test itself it shows failed. Could please someone tell us why it got failed. We have 4 other similar boards working fine , but we got one board failure during ddr4 testing. We tried with different clock frequency as well in the configuration setup. Attached screenshot for reference. Please help us to solve the issue.

Hello,

Since other boards with the same layout are passing the DDR training and one is failing, I suggest you check in Hardware side, DDR, USB debug and data USB layout issues.

Best regards.
