MCXN947 Coolflux BSP32 Use?

[Radar12345]

The datasheet and reference manual for the MCXN947 mention the coolflux BSP32 processor. This processor appears to be suitable for DSP processing. However, I can find no documentation or examples on how to program this processor. Do any exist?

Hello

I hope you are well. You can find some examples on how to use this co-accelerator in the SDK. Welcome | MCUXpresso SDK Builder (nxp.com)

Best regards,

The link you have provided only links to a welcome page for the MCUexpresso SDK builder and has no mention of coolflux or BSP32. I have looked at the examples in MCUexpresso and can not identify any which include the coolflux processor. Is it possible for you to give the name of the example projects that include the coolflux processor or provide a link to webpage that describes how to use it within the MCUexpresso IDE.

When building the SDK make sure that all middleware is selected. Please follow this video to import the SDK to the IDE: MCU Tech Minutes | NXP Semiconductors
Examples are found under the prefix powerquad.

PowerQuad itself cannot execute programmable programs independently, so it is not a processor, it is just a co-acceleration module that can be accessed through the co-processing interface, and can only accelerate specific math-related functions.

My question was not about the powerquad processor which is documented in chapter 18 of the MCXN947 reference manual. My question is about the coolflux processor which is documented in chapter 21 of the same reference manual. I have used the powerquad to perform FFTs of various sizes using the example code. I know the powerquad can not be programmed as such. I want to know about programming the coolflux processor whos block diagram from the MCXN947 reference manual I show below.

From your response it appears the MCUexpresso IDE does not support use of or programming of the coolflux processor on the MCXN947, is that correct?

I have now been in contact with a NXP rep and they have informed me that there are no public tools available for compiling CoolFlux software. Therefore it is safe to say MCUxpresso IDE does not at present support the use of the Coolflux processor on the MCXN947.
