Compatibility issue between S32K344 and S32K324

Hi，I have encountered the following problems recently, please help to answer , thanks.

1、Can S32K324 and S32K344 be obtained from each other by decoupling and locking steps?（mass production phase）

At present, P32K344 and P32K324（sample stage） of my test are able to free to decouple and lock step.

2、Can S32K324's project be downloaded to S32K344? If so，what needs to be changed?

Expecting a reply. TKS.

Hi @Chenxu1

1. Can S32K324 and S32K344 be obtained from each other by decoupling and locking steps? (mass production phase)
It is not possible because the production MCU comes with this feature locked.

2. Can the project be downloaded from S32K324 to S32K344?
It is not possible because there are several settings made in the project that will cause failures on other devices different than the version for which the project was created. I am afraid that the most viable option is to generate a new project with the corresponding MCU and then copy the application source files from your pre-existing project as well as any customizations you made to the project properties.

After the decoupling process, the S32K344 effectively becomes the S32K324. This point has already been clarified in the discussion at https://community.nxp.com/t5/S32K/How-do-I-configure-SMP-FreeRTOS-on-the-S32K344/m-p/2295127#M56161, and I would like to verify it with you once more.
