Hi,

I want to write bootloader for S32K144 using CAN protocol but not getting any reference code.

I'm using S32DS v 3.4 and SDK v 4.0.1.

Can I get example code of CAN bootloader?

We provide application note “S32K1xx Firmware updates” discussing A/B swap and using CAN interface:

There are SW examples for S32K144 and S32K146.

S32K144 has one read partition on program flash, so it is not possible to update the application while the old application is still running.

S32K146 has more read partitions on program flash, so old application can run during the update.

Regards,

Lukas
