Hi, I am currently looking at S32K116 series MCU, would like to know the firmware upgrade via UART.
So for the UART, do I need to connect two lines (Rx,Tx) only or 4 lines with flow control?
I would like to recommend you AN12218 S32K1xx Serial Bootloader with SW located on this link in the Application note section 32-bit Automotive General Purpose MCUs | NXP
Hardware flow control is supported but it depends on your application requirements. You do not have to use it.
I hope it helps.
