I want to use the rappid BL tool to program the s32k144 MCU. What kind of physical interface should I use? Can a USB/Serial converter like a FTDI be? Is there any MCU specific UART for this connection?
if you are using EVB - you can use OpenSDA interface which is acting as COM port. The boodloader firmware is using LPUART1.
I tried this but the below error occurs:
did you successfully upload the bootloader firmware itself into EVB? (the .rbf file). You can copy it into openSDA mass storage or upload it as normal .srec file.
