The RT600 does not come with internal flash but with external flash connected to the FlexSPI bus, only. The external FlexSPI controller allows to connect several different flash types like QSPI, HyperFlash and Octaflash. Furthermore, the external flash can be connected to different pin / ports of the FlexSPI controller which makes a auto-detection kind of difficult thus a out-of-the-box solution which works for all setups is kind of impossible. For that reason, the J-Link software supports the evaluation board setup, only. Other setups may follow. If you are working with a different setup and looking for support for this setup, please get in touch with the J-Link team.
