S32k148 - Firmware update methods

sathish_sekar — Tue, 28 May 2019 12:13:19 GMT

I am working on firmware update methods for s32k148.

I have seen a/b swap firmware update mechanism in https://www.nxp.com/products/processors-and-microcontrollers/arm-based-processors-and-mcus/s32-automotive-platform/32-bit-automotive-general-purpose-microcontrollers:S32K?&tab=Documentation_Tab&linkline=Application-Note

for s32k146.

i.e Referring the application note https://www.nxp.com/docs/en/application-note/AN12323.pdf.

It contains information for s32k144/146.

I looking the same for s32k148.

Is this already available in nxp forum or I should create for myself??

Could anyone provide details for firmware updates in s32k148(evb)?

Hi Sathish,

there's version only for S32K144 and S32K146. It's supposed to be sample code only, so if you need to port it to S32K148, it's necessary to do that by yourself. S32K148 is superset of S32K146, so it should be quite easy to port it.

If you need just simple bootloader (no A/B swap), there's also AN12218:

Hello Lukas,

Thanks for the response.

Porting the project form s32k146(https://www.nxp.com/docs/en/application-note-software/AN12218SW.zip) to s32k148 is the best option, and current i am trying this.

Thanks an Regards

Hello Lukas,

Source code to build file .bin (blink led) any special things? It is built by S32Ds or other IDE?

If you have this source, please send to me.

Thanks and Regards
