I´m using a S32k14x (or plan to use) in a automotive application.
The only connection to the outside world in a LIN bus. So, a UART port together with a LIN transceiver should be fine.
However, my question concerns the ROM-based bootloader and if it possible to use the in a "LIN setup".
With that I mean that once the host has send the command to reboot and start in bootloader mode (using a LIN 2.0 Protocol), it could start sending commands by the protocol defined by the NXP bootloader implementation.
I´m not too familiar with the LIN interface but would it be possible to use the UART bootloader via a LIN transceiver?
