Program S32K142 Over CAN

Hi,

I am trying to find a can bus supporting bootloader for the S32K142 (I'm currently working on the eval kit however this will soon be a custom solution). The application is automotive and the requirement is to be able to update the firmware remotely via can once the device is fitted and not easily accessible.

The application code is built using the model based design toolbox and the ideal solution to update the firmware is to have a (windows) gui in which to load the .elf file and set the application code start address and code size range, then program from the PC over can. For initial bootloader programming, programming over JTAG or by using the OpenSDA is acceptable.

It looks like the RAppID BL Tool is the best option, however the latest version (1.6.7.35) only supports the S32K144 under the MCU drop down menu. Is there an available bootloader for the S32K142 which would enable this use case?

Thanks

Jonny

Hi Jonny,

You can use the Unified Bootloader, it is ported to S32K142.

Thanks Daniel,

Thanks, based on other posts in the community forums, I have now also raised a support ticket (00414468), requesting the NXP OpenBus software tool used to flash the chips as there's no download available.

Thanks

Jonny
