Program a S32K from a 820A via SWD?

Question asked by Perig Vennetier on Dec 4, 2018



I'd like to setup an embedded system to be able to have a Snapdragon 820A program a S32K144 via SWD but it seems that 820A does not support SWD natively.


Anybody would have seen a solution to do the above?


Would there be a chip that can be the bridge between SPI and SWD for example?


Could any GPIO be used on the 820A to become a SWD channel by creating custom timing?
