We are generating code for arm cortex m using embedded coder and arm cmsis.According to documentation

In the setup for code replacement the libary can be changed.

Question

1. Is it possible to uses later version of cmsis and cmsis-dsp for example 1.16.2 of cmsis-dsp?

Hi Sebastian,

I understand you are trying to use a specific version of CMSIS library. You can very well do that using the CMSIS package window that pops up after running the following command:

launch(cmsisToolsObj)

Just make sure to uncheck “Use CMSIS package downloaded and installed with support package” on the 2nd window. When you press next, it will let you browse a specific CMSIS folder, which could be any downloaded version you choose. If in case you face error due to version compatibility, you can always move to a latest version of MATLAB (R2025b).

Regarding your second question, yes, the code is affected by the version due to some functionality not being available in the older versions. Make sure to go through the library functions within the folder to understand which version works best for you.

Hope this helps!
