S32K142 boot/bootloader from CAN

[Dani_mj]

Hello

In my project we've prepared a PCB where the S32K142 is connected via CAN to a master uC.

My problem is that I've trying to find how to load the initial bootloader + firmware using the master uC.

Is there any kind of pinout sequence + CAN communication that allows this first load of firmware?

Or is mandatory to preload the bootloader before soldering the S32K142 to the board?

Thanks in advance

Hello,

Unfortunately, flash is in an erased state on the brand new S32K device. The bootloader must be programmed to the flash by JTAG/SWD.

Best regards,
