latest SDK version & MCUXpresso IDE version

[ping1]

Dear all

I have not been here for a while, I am still using MIMXRT1024-EVK, and planning a new project based on that again, and just try to update my SDK, and just noticed it is suddenly jumped form v2.15.0 to v24.12.0, same with the IDE, jumped from v11.8.x to v24.x, just wonder what is the big change and compatibility issues, i.e. do I have to use both v24?

Thanks!

Hi @ping1 

Apologies for this big and tough update. 

Compared with the previous software architecture, SW24 has indeed made great changes, but it also brings many problems for new starter. From my side, if the project time and resources are tight, it is not particularly recommended to use the latest SDK completely.

Please see the release note about SDK SW24.12, it will depend on the below developement tools if you have to use SDK SW24.xx

• MCUXpresso IDE, Rev. 24.12
• Keil MDK, version is 5.41
• GCC Arm Embedded Toolchain 13.2.1
• IAR Embedded Workbench for Arm, version is 9.60.3
• Xtensa C Compiler, version is RI-2023.11
• Xtensa Xplorer, version is 10.1.11
• CodeWarrior Development Studio v11.2
• RISCV LLVM 14.0.0
• MCUXpresso for VS Code v24.12

Hi @ping1 

Here I would like to clarify the releationship between MCUXpresso SDK and MCUXpresso IDE version as follows:

• IDE v24.x supports all previous SDK versions, reflecting downward compatibility.
• SDK v24.x requires a higher version of IDE, which is a change in version dependency rather than a compatibility issue.

You can keep different IDE versions(e.g IDE v24, v11.xx) and different SW SDK versions(e.g SDK v2.15/16, v24.12).

• If you want to use the latest SDK v24.12, you have to use IDE v24.
• If you want to use previous SDK, v2.15, v2.16 for example, you may use latest IDE v24 or previous IDE v11.xx.
