NXP IMX DDR Tool MX8ULP issues

ksingh — Tue, 29 Jul 2025 15:37:45 GMT

I am working with the i.MX8ULP processor (MIMX8UD3CVP08SC, revision A2) on my custom PCB. I am working with (effectively) the same DDR as the EVK (MT53E512M32D1ZW-046AUT:B), however I am using the LPDDR4x mode.

I am having trouble with running the NXP IMX DDR Tool, receiving chopped off debug, and hanging at the log pasted below.

[RESULT] Download is complete Waiting for the target board boot... ===================hardware_init===================== OCK Set BUCK3 to 0.9v hardware_init exit ************************************************************************* ************************************************************************* ************************************************************************* NXP DDR Tool V1.00 Built on Apr 28 2023 11:20:51 ************************************************************************* Waiting for board configuration from PC-end...

The NXP IMX DDR Tool only accommodates for revisions A0 and A1. Is there an updated IMX DDR Tool for the A2 revision?

I have successfully set up my COM communication for the A-Core LPUART7. Does this look right?

Hello,

There is not an updated DDR Tool version for i.MX8ULP and you customization to use LPUART 7 is correct.

I suggest you check the connection between your board and the PC (data and debug cables).

Best regards.
