iMX DDR Config Tool Code Generation Error || iMX95

Sudharsun — Tue, 15 Sep 2026 06:23:13 GMT

Hi Team,
We are currently working with the NXP Config Tools for i.MX95 DDR configuration and are facing an issue while generating the DDR initialization/timing code.
We created/opened the DDR configuration for the following target:

Processor: MIMX9596xxxxN
Core: Cortex-M33
Memory Type: LPDDR5 - Ryzen RS2G32LO5D4FDB-23BT
DDR Data Rate: 6400 MT/s
Number of Ranks: 2
Number of 16-bit Channels: 2
DRAM Configuration: 16Gb:2Gb x8
Total DRAM Density shown by the tool: 16384 MB

Initially, we are trying to validate the DDR configuration using the NXP i.MX95 19x19 EVK default LPDDR5 configuration before applying our custom board DDR settings.
However, when we try to generate/update the DDR code, the Config Tools reports an error in the Problems window:

“Failed to generate code…”

and the Code Preview window shows:

“Code generation failed.”

The screenshot of the issue is attached for reference:

1. I downloaded and installed Config_Tools_for_i.MX_26.06_x64.

2. I created a new configuration, select "IMX95LPD5EVK-19" under "Boards". Enable DDR tool and select it.

3. Click "File->Save" to save this project to the disk. Then "Update Code" is avaiable.

4. Click "Update Code" button, there is no error on my side.

Hi,

The issue still persists. Even after saving the .mex file to the local disk, the code is not being generated. When I click Update Code, the tool throws the error “Code generation failed.”

Did you install Config_Tools_for_i.MX_26.06_x64? The latest version 26.06?

Did you using the Linux version? I am using the Windows version.

Would you please send your IMX95LPD5EVK-19.mex to me to do verification?

Hi,

Yes, we have downloaded and installed the same version that you mentioned. We are currently using the Linux version of the tool. I have attached a screenshot for your reference.

Hi,

I have attached the .mex file for your reference but we are going to use 8GB LPDDR5 Rayson RS2G32LO5D4FDB-23BT.

Hi,

Could you please check and provide an update on this issue at the earliest? We are currently running short on the project timeline, so your prompt support would be greatly appreciated.

It is mandatory to install this version configs tool on Ubuntu 24.04.

I can reproduce your problem on Ubuntu 22.04.

Then I install configs tool 26.06 on Ubuntu 24.04 OS, it worked normally.
