S32K344 Bootloader

DM123 — Thu, 21 Aug 2025 15:34:32 GMT

Hi,

I am intending to develop a bootloader for the S32k344 micro which supports XCP over CAN.

I already have a CAN driver for this MCU?

Questions:

1. Any idea where i can get an XCP stack?

2. Have you got a base bootloader with sufficient Flash handler/driver that I use as a base line?

Hi,

there is unified bootloader which can be downloaded here:

Notice that it’s demo software only with no guarantees and no support.

If production code is required then check third parties like Vector, which can offer XCP stack as well as NXP does not provide any:
