Hi NXP Team,
I am working on updating the S32K14x MCU Software from USB device. Is there any possible way or example project to understand how to implement it.
Best Reagds,

Hi @baseerahmadpiracha
S32K14x does not have USB module, so an option is to use USB-to-UART interface and then use serial bootloader.
We have this application note discussing serial bootloader. Sample code is included:

And regarding USB-to-UART interface, I can recall that FTDI chip FT2232D was used on one of our EVBs.

Hi @lukaszadrapa
Thank you for your reply. I have successfully updated the SREC file through Java application but I am not able to run the application. I don't know whether the code is jumping to application after update or not.
Please guide me. Thanks
Which debugger do you use? If you use S32 Design Studio, you can attach to a running target and then you can check the current state:
