Is "DSP System Toolbox Support Package for ARM Cortex-M Processors" available for Matlab R2022a?

On trying to install DSP System Toolbox Support Package for ARM Cortex-M Processors, Matlab reporting that it is incompatible

Thanks very much,

John

[Steven Lord]

Can you show us the full and exact text of the error message you receive? The full message may include information about the root cause that is not available in the paraphrase "it is incompatible". Also, can you tell us on what OS you're trying to install this support package?

[John Edwards]

Windows.

The error message doesn't say any more than my message:

The support package is not compatible with your version of MATLAB or operating system

[Walter Roberson]

Which Windows version are you using?

[John Edwards]

Windows 11

If anyone is interested, in this, in the future then "DSP System Toolbox Support Package for ARM Cortex-M Processors" is not required with R2022a.

A working example, using DSP.fft() is included here:

The Release Compatibility information for that support package states that it is compatible with release R2014a through R2018b.

I do see what I believe is a related support package, Embedded Coder Support Package for ARM Cortex-M Processors. I'm not really familiar with these support packages, but the overview sections sound like the Embedded Coder support package may be the successor for the DSP System Toolbox support package. Its Release Compatibility information states that it's compatible with releases R2014a through R2022a.

[John Edwards]

The URL for the support package says "This support package is functional for R2013b and beyond."

[Walter Roberson]

The Embedded Coder Support Package is

Created with R2014a

Compatible with R2014a to R2022a

but the DSP support package is

Created with R2014a

Compatible with R2014a to R2018b

Look at the "MATLAB Release Compatibility" information on the right.

If you look at the System Requirements table,

https://www.mathworks.com/hardware-support/system-requirements.html

notice that there are no entries for DSP System Toolbox Support Package for ARM Cortex-M Processors after R2018b.

Thanks Walter,

My understanding (maybe wrong) is that the DSP System Toolbox Support Package is required for executing functions such as DSP.fft() on Arm Cortex-M series, using the CMSIS-DSP functions.

Can you tell me if there is another way to achieve this?

FYI, I've tried the same using the Embedded Coder Support Package but this only seems to support the standard Matlab fft() functions, not the DSP functions.

@Walter Roberson, @Steven Lord,

Just wondering if either of you know how to get DSP.fft() running on the Arm Cortex-M series?

The "DSP System Toolbox Support Package for ARM Cortex-M Processors" seems to be the way but if it doesn't work with R2022a then is there an alternative?

Thanks very much,

John

@John Edwards

Sorry, I have never used DSP.fft() or Cortex-M

[John Edwards]

No worries, thanks @Walter Roberson
