No Flash Algorithms for S32K388 in CMSIS Pack

kscz — Fri, 12 Jun 2026 18:03:52 GMT

I am attempting to use the S32K388 in a number of designs but I see there are no flash algorithms for it in the CMSIS pack - https://www.keil.arm.com/packs/s32k3xx_dfp-keil/devices/

Is there plans to add this? How quickly could I get an updated file for this?

Hi@kscz

This is beyond our support scope. you should seek for help from KEIL support.

Based on current information, KEIL's DFP package hasn't been updated and doesn't support all S32K3 models.

You will need to implement your own S32K388 programming algorithm.

(I have created a KEIL question thread to inquire about future update plans for the S32K3 DFP.)

Bummer - I was hoping I wouldn't need to figure out how to write my own flashing algorithm...

I can translate the rest of the fields based on things like the memories files, but the flashing algorithm is currently a bit beyond my knowledge.

Do you have a link to the Keil thread? Do you happen to have any insight into why the current DFP is deprecated?

Hi@kscz

copy the content for your reference:

The pack S32K3xx.DFP is clearly marked as 'Deprecated'. Please see:
https://www.keil.arm.com/packs/s32k3xx_dfp-keil/devices/

This means that there will be no further updates from our company. We stopped maintaining DFPs for NXP quite some time ago, and NXP created lots of DFPs for other devices, but obviously not for this series. So it's up to NXP to create a new DFP for the S32K3 series.

Meanwhile, I'm trying to confirm with the development team whether NXP will continue to support the DFP package. However, I haven't received any information yet.

Any updates? Will NXP support updating these tools in the Keil toolchain?

Hi@kscz

Sorry, I forgot to forward the message I received to you.

The internal response was very clear.

"So far, NXP have not plan to update the S32K3xx' DFP of KEIL ."
