IMX8M PLUS LPDDR4 2G compatibility

TMpieye — Tue, 20 Jan 2026 07:41:50 GMT

We try to implement an ISSI IS43LQ32512A-046BLI 2GB RAM. After Calibration the RAM fails during the memcpy SSN armv8_x32 test with 2000MHz configured.

If I configure the RAM to 1500MHz it pass all the tests.

Has anybody implement this LPDDR4 RAM? Is it in general compatible with IMX8M PLUS?

Hello @pengyong_zhang ,

Same result with the config Tool V 13.1. Maybe our configuration is wrong for the IS43LQ32512A-046BLI? Can you provide the correct configuration (*.ds file)? Our hardware desing is a 1:1 copy of the eval board regarding the LPDDR4 interface.

Kind Regards

Tobias

Hi @TMpieye

Did you run the stress test with our DDR Config Tool? From your log file, it seems not from the Config Tool output. Also use out latest tool version v25.12.

Hello @pengyong_zhang ,

I run the tes in the config tool and and its passed. So it seems to be a tool problem with the MSCALER tool. Many thanks for your great support!
